Abstract

Standby current of an arithmetic control unit configured to perform a control operation based on an activation signal generated by an unspecified manual operation is prevented. A power supply relay configured to supply power to an arithmetic unit is operated such that it is closed by a power supply switch, thereby applying operational control to a main electrical device and operational control to an auxiliary electrical device, according to a composite activation signal generated by an activation signal processing unit, in response to closing operations of activation command elements, even when the power supply switch is open.As a result, the standby current generated in the activation signal processing unit is significantly reduced compared to a case where the arithmetic unit is activated in the meantime.

Description

Background of the invention 1. Field of the invention

[0001] The present invention relates to an improvement of an on-board vehicle electrical control device, comprising an activation signal processing unit configured to supply energy from an on-board vehicle battery for control in order to perform drive control of a main electrical device during a period in which a power supply switch for a vehicle drive is closed to be in a conductive state, and is suitable for performing drive control for an auxiliary electrical control device even when the power supply switch is open to be in a disconnected state.In particular, the present invention relates to an improvement of an activation signal processing unit of an on-board vehicle electrical control device, which is suitable for a case in which the main electrical device is a motor control unit which is suitable for supplying energy from an on-board vehicle main battery to operate a motor for driving an electric vehicle, and the auxiliary electrical device is a charging control unit which is configured to charge the main battery and an auxiliary battery for control, from a ground power supply. 2. Description of the state of the art

[0002] With reference to Fig. 1 in JP 2015-089 152 A entitled "Energy Storage System", which is a configuration example of an on-board vehicle device configured to charge an on-board vehicle main battery configured to supply energy to a motor for propulsion of an electric vehicle from a ground power supply, a mounted battery configured to supply energy to a motor-generator connected to a main relay is charged from a ground DC power supply via a first charging relay or from a ground AC power supply via a second charging relay. Furthermore, the main relay and the first and second charging relays are selectively closed by an on-board vehicle control unit.

[0003] A standard commercial household AC power supply is used for low-current, long-period overnight charging. A key characteristic of AC power supplies is that they do not require a ground auxiliary device; simply connect a charging cable to the AC power supply. This type of power supply is generally referred to as "normal charging." Meanwhile, a DC power supply is installed in a charging station and enables high-current, short-period charging. DC power supplies are therefore used for temporarily topping up an insufficient amount of remaining charge in a short period away from home or the office and are generally referred to as "fast charging."

[0004] With reference to Fig. Section 1 of Japanese patent publication number 2011-114962, entitled "Charging system, charging unit, motor-driven vehicle and method for charging a battery for the motor-driven vehicle (hereinafter referred to as "charging system")", is an example of a DC power supply system suitable for fast charging as a ground-based device. The charging cable for connecting a ground-based charging unit and an electric vehicle comprises a charging line for supplying power, a combination line using a digital signal, and a control line using an analog signal. Furthermore, signals for initiating and terminating a charging control sequence between the charging unit and the electric vehicle are communicated, and a communication method for this is described in accordance with the CHAdeMO (trademark) standard.

[0005] Furthermore, with regard to Fig. 2 and Fig. 4 in JP 2014-030 283 A entitled "External Power Supply Unit for Electric Vehicles", designed to perform normal charging from a commercial AC power supply and also to supply power to domestic electrical appliances, comprises a charging gun for battery charging, which is to be connected to a normal charging port or an adapter for a domestic electrical appliance power supply, a second resistor connected in series with a first resistor in parallel, and a switch connected in parallel with the second resistor. Furthermore, a third resistor is connected in parallel to a series circuit of the first and second resistors on one side of the vehicle, and a fourth resistor is connected in series with the third resistor such that a reference voltage is applied to it.Furthermore, the values ​​of the first and second resistors are different from each other, between the charging gun and the adapter, and a vehicle control unit receives a voltage between both ends of the third resistor as a link signal to detect which is connected to the charging gun or to the adapter in order to perform charging control or discharging control.

[0006] With reference to Fig. 3 in WO 2013 / 054 387 A1 entitled “Charging control devices for a vehicle and vehicle equipped therewith”, which is designed to prevent a reduction in battery voltage due to a standby current (dark current) consumed when a vehicle system is stopped, in the normal charging system and the fast charging system: (1) until an initial signal (connection of a charging cable) indicating an intention to make a charging request from a user is detected, a main clock is stopped, and a mode is set to an initial rest mode (sleep mode) in which the initial signal is received as a device interruption; (2) when the initial signal is detected, the main clock is operated, and the mode continues with a normal mode (wake-up mode);(3) when charging is complete, the mode continues with an intermediate activation mode, alternating between a second sleep mode (wait mode) in which the main clock operates and the normal mode (wake-up mode); and (4) when a second signal (disconnection of the charging cable) indicating the user's intention to stop charging is detected, the mode continues with the first sleep mode.

[0007] DE 10 2009 017 501 A1 describes in connection with the there Fig. Figures 1 and 6 describe a vehicle electronic control device comprising a main CPU (MCPU) and a secondary CPU (SCPU), wherein a power supply relay 102 is activated in response to the closing of a power supply switch 103. The main CPU is powered by electrical energy from a vehicle battery via a power switching element and a main power supply circuit to control a variety of electrical loads according to the operating states of a variety of input sensors. The secondary CPU is powered by electrical energy from the vehicle battery via a secondary power supply circuit to monitor the operation of the main CPU and input signals. The secondary CPU has a low speed and small memory capacity to operate with lower power consumption compared to the main CPU. (1) Description of problems from the state of the art

[0008] In the systems of normal charging using commercial AC power supply and fast charging using the floor charger, described in JP 2015-089 152 A, in JP 2011-114 962 A and in JP 2014-030 283 A, certain roles of the on-board vehicle electrical control device are not described, however, WO 2013 / 054 387 A1 addresses the following problem, which proposes measures to prevent standby current (dark current), that is a problem for the on-board vehicle electrical control device for these charging systems.The on-board electrical control device, which is included in an electric vehicle, integrally controls a motor control unit, configured to operate when a power supply switch is closed, thereby controlling a power conversion unit for the motor during operation, and a charging control unit, configured to operate primarily when the power supply switch is open, thereby controlling a power conversion unit for a main battery for motor propulsion. Thus, the program memory capacity of a main CPU, which is a microprocessor that forms the on-board electrical control device, is substantial, and the start-up delay period required for its initial inspection and the run-on period required for processing and saving the current state before stopping operation are also increased.As a result, for example, 1 second of an inactive period occurs once during activation and once during a stop.

[0009] However, connecting and disconnecting the charging cable and switching the ground power supply switch on and off are manual operations, and therefore the period from connecting the charging cable to switching on the ground power supply switch can be of an indefinite length. Similarly, the period from the completion of battery charging until the disconnection of the charging cable can also be of an indefinite length.

[0010] Accordingly, the total period between activations, which occurs from connecting to disconnecting the charging cable, can be of indefinite length. Furthermore, while an intermediate activation interval must be short to quickly detect the times of connecting and disconnecting the charging cable, a power supply is required for the inactive period of the microprocessor described above (e.g., 1 second) or more for a single intermediate activation.

[0011] As a result, if the on-board vehicle's main battery for motor propulsion is being charged from the ground power supply in an unattended state, it is difficult to prevent standby current from being applied to the electric vehicle by using the intermediate activation of the on-board vehicle's electrical control device, and a more effective measure must therefore be used. Summary of the invention (2) Description of the problem of the invention

[0012] The present invention provides an activation signal processing unit equipped with a plurality of activation command elements to prevent the generation of standby current in an entire arithmetic control unit. The arithmetic control unit, which is powered by an on-board vehicle battery via a power supply relay configured to respond to a closing operation of a power supply switch in order to perform operational control of a main electrical device, is configured to be activated to apply operational control to an auxiliary electrical device in response to closing operations of the plurality of activation command elements, even when the power supply switch is open.In particular, the present invention provides an on-board vehicle electrical control device comprising an activation signal processing unit suitable for charging control to be applied to an electric vehicle.

[0013] According to at least one embodiment of the present invention, an on-board vehicle electrical control device is provided, comprising an activation signal processing unit. The on-board vehicle electrical control device comprises an arithmetic control unit configured to execute a control program, which acts as a main control operation means to initiate a control operation by applying a stabilized voltage Vcc from an on-board vehicle battery, through a power supply relay configured to respond to a closing operation of a power supply switch and supply stabilized power, thus generating a normal operating signal RUN, maintaining a closing operation of the power supply relay, and monitoring the operating control for a main electrical device and the response state to the operating control.The arithmetic control unit is configured to transfer and store at least a portion of the latest current information (current information) in a non-volatile memory when the power supply switch is opened, then to suspend the normal operating signal RUN and discharge (disengage) the power supply relay, thus stopping it. The arithmetic control unit is also configured to execute a control program that serves as an auxiliary control means for activating the arithmetic control unit in response to closing operations of a variety of activation command elements, even when the power supply switch is open, and to monitor the operating control of an auxiliary electrical device and the response state to that operating control.The activation signal processing unit comprises a plurality of individual activation processing units into which corresponding activation command signals are input, each responding to an open and a closed state of the activation command element. Some of the plurality of activation command elements are configured to generate the activation command signal, which has an indefinite and short period and is represented by push-button switches, while others are configured to generate the activation command signal, which has an indefinite and long period and is represented by toggle switches or push / pull plugs, to be changed to a closed and / or an open state by a manual operation.

[0014] Furthermore, each of the multiple individual activation processing units comprises an activation interlock unit configured to store a generation of one of the activation command signals, coupling composition of the activation signal STn to each other, each of which is an output signal from the activation interlock unit to form a logical OR in order to thereby generate a composite activation signal, and to generate a single activation signal SIG3n for the single input of a generation state of one of the activation command signals into the arithmetic control unit.The arithmetic control unit is configured to: initiate control operations when the stabilized voltage Vcc is applied across the power supply relay to operate in response to the composite activation signal, and to maintain the operating state of the power supply relay; and to read the individual activation signal SIG3n to perform the operational control for the auxiliary electrical device, and to generate an activation signal disconnect command CNT3n2 to halt the output of the activation interlock unit until the generation of the normal operating signal RUN is halted, either as a result of an operation confirmation associated with the operational control or upon the determination of the elapsed time of a predetermined period. The individual activation processing unit further comprises a disconnect interlock unit and a restore determination unit.The separation interlock unit is configured to be operated by the activation signal separation command CNT3n2 and to stop the generation of the composite activation signal STn when the plurality of activation command elements are in a normally closed or an irregularly closed state. The reset determination unit is configured to reset the separation of the interlock unit when the plurality of activation command elements are in a normally open or a return-to-open state and to allow the generation of the composite activation signals STn when the plurality of activation command elements is closed.

[0015] As described above, the on-board vehicle electrical control device, which includes the activation signal processing unit according to at least one embodiment of the present invention, comprises the arithmetic control unit configured to supply energy from the stabilized power supply during an operating period in which the power supply switch is closed, in order to perform the operational control of the main electrical device, for example, to transfer and store learned information or an irregularity occurrence frequency information that has occurred during the operating period from a volatile working memory to a non-volatile data memory or a program memory, while the power supply state is maintained according to the normal operating signals RUN, even when the power supply switch is open and brought into a state in which the power supply is stopped.When the normal operating signal RUN is suspended, as a result of memory processing completion, the on-board vehicle electrical control unit includes a single activation processing unit configured to respond to the open / closed states of the activation command signals S31, S32, and S3n generated by the plurality of activation command elements. The single activation processing unit comprises the activation interlock unit, configured to individually store the generation of the activation command signal S3n (n = 1, 2, ..., N) and to generate the composite activation signals STA through STC, obtained by coupling the output signals of the activation interlock units together to form the logical OR gate.and for generating the individual activation signal SIG3n for individually inputting the generation state of the activation command signal S3n into the control input terminal of the arithmetic control unit.

[0016] Furthermore, the arithmetic control unit is configured to apply the stabilized voltage in response to the composite activation signal, thereby initiating the control operation and maintaining it in the power supply state corresponding to the normal operating signal RUN. The arithmetic control unit is also configured to read the individual activation signal SIG3n, to apply the operating control to a part of the auxiliary electrical device, and to stop the generation of the normal operating signal RUN in response to a reply signal or an excessively long elapsed period.

[0017] Thus, if the activation command of the element is, for example, a push-button switch, and a push-button operation is performed for a relatively short period—even if the push-button period is shorter than the voltage rise period of the stabilized power supply and the inactive period of the arithmetic control unit required for a necessary self-diagnostic period—the composite activation signal can be safely generated by the activation interlock unit to activate the arithmetic control unit. Before the arithmetic control unit stops operating, the composite activation signal can be released by the disconnect interlock unit. Therefore, the following effect is provided: various types of auxiliary control can be performed by the arithmetic control units, even when the power supply switch is not closed.This also provides an effect that prevents the creation of an unnecessary energy supply state, thus preventing wasteful discharge of the on-board vehicle battery, by releasing the composite activation signal at a time when the auxiliary control by the arithmetic control unit is completed, even if a short-circuit irregularity occurs in the push-button switch, or the activation command element performs an indefinitely long period that completes an operation.

[0018] Furthermore, once the closed activation command element is opened, the recovery determination unit releases the separation operation through the separation interlock unit. Thus, when the activation command element executes the indefinitely long period that completes an operation, the auxiliary control is released again by the activation command element closing once more, and the separation interlock unit is activated to perform a power-saving operation during the closing operation for a long period. Therefore, the following effect is provided. The common single activation processing units can be applied even if the activation command elements differ from each other in operation properties.

Description of embodimentsFirst embodiment[Detailed description of the first embodiment](1) Detailed description of the configuration

[0019] A detailed description will now be provided from a configuration. Fig. 1 given, which is an overall circuit block diagram of an on-board vehicle electrical control device comprising an activation signal processing unit, according to a first embodiment of the present invention.

[0020] In Fig. 1. An on-board vehicle battery voltage Vbs is applied from an on-board vehicle battery 101, for example, a 12 V DC system, to the on-board vehicle electrical control device 100A. An operating power supply voltage Vbb is applied via a power supply relay 103A, which is charged (energized) when a power supply switch 102 is closed. Furthermore, a main electrical device 104, which is controlled to operate when the power supply switch 102 is closed, is connected to the on-board vehicle electrical control device 100A. The main electrical device 104 consists of an electrical load group 1 and a sensor group 1.

[0021] An auxiliary electrical device 105, which is controlled to operate when the power supply switch 102 is open, is further connected to the on-board vehicle electrical control device 100A. The auxiliary electrical device 105 consists of an electrical load group 2 and a sensor group 2.

[0022] An auxiliary activation signal group 106A, connected inwards or outwards from the on-board vehicle electrical control device 100A, is formed from auxiliary activation command circuits 21 to 28 (hereinafter sometimes referred to as “2n” and the same applies below), which are formed by mutually connecting, in series, activation command elements 21a to 28a (hereinafter sometimes referred to as “2na”) and short-circuit-to-energy current limiting value resistors 21b to 28b (hereinafter sometimes referred to as “2nb”), and each configured to generate an activation command signal S3n.

[0023] Part of the activation command elements 2na is configured to generate the activation command signal S3n, which is indefinite and short, and is represented by push-button switches. The other part is configured to generate the activation command signal S3n, which is indefinite and long, and is represented by toggle switches or push / pull plugs that are to be changed to a closed or open state by manual operation. The short-to-energy current-limiting resistor 2nb is intended to protect against a short circuit if the activation command element 2na is in contact with a power line on its positive side.

[0024] Furthermore, the number of auxiliary activation command circuits 2n is not limited to 8 and is increased or decreased according to an order of magnitude of the overall system.

[0025] The on-board vehicle electrical control device 100A mainly comprises an arithmetic control unit 120A, which includes a main CPU, which is a microprocessor, and an activation signal processing unit 130A.

[0026] A stabilized power supply 110, configured to generate a stabilized voltage Vcc, for example a DC voltage of 5 V, from the operating power supply voltage Vbb, is connected to the arithmetic control unit 120A. The arithmetic control unit 120A comprises a main CPU, a non-volatile program memory PMEM, a data memory DMEM, a volatile working memory RMEM, and a multi-channel analog-to-digital converter (ADC). The main CPU is powered when the power supply relay 103A is charged. The arithmetic control unit 120A is configured to work in conjunction with a runtime monitor (monitoring timer) WDT to generate a normal operating signal RUN during normal operation.

[0027] Furthermore, when the power supply switch 102 is closed, the power supply relay 103A is charged via an operating signal assembly circuit 113 and a power supply relay operating element 112. Finally, when the main CPU is activated and the normal operating signal RUN is generated, the main CPU operation continues through the operating signal assembly circuit 113 and the power supply relay operating element 112 when the power supply switch 102 is opened. The control operation is completed by executing a predetermined halt processing to stop the normal operating signal RUN.

[0028] A backup power supply 114, configured to generate a backup voltage Va, for example a DC voltage of 5 V, from the vehicle's on-board battery voltage Vbs, is connected to the arithmetic control unit 120A. However, important information, such as learned data and irregularity occurrence frequency information, stored in the RAM memory RMEM during main CPU operation, is transferred to the non-volatile data memory DMEM during a delay period immediately after the power supply switch 102 opens. Then, the normal operating signal RUN is stopped, and the power supply relay 103A is discharged.

[0029] Meanwhile, when the power supply switch 102 is closed and a power supply switching signal PWS is thus generated, an operation start signal SIG0 is input into the main CPU via an operation start instruction element 111s, which is, for example, an NPN transistor, to perform an operating control for the main electrical device 104.

[0030] However, even if the power supply switch 102 is open when the activation signal processing unit 130A generates a composite activation signal STA, the power supply relay is charged by the operating signal composite circuit 113 and the power supply relay operating element 112. Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal composite circuit 113 and the power supply relay operating element 112, even if the composite activation signal STA is stopped. When the operating circuit of the auxiliary electrical device 105 is completed as a result, the auxiliary control operation is completed by performing a predetermined stop processing to stop the normal operating signal RUN.

[0031] A plurality of individual activation processing units 13n (n = 1 to 8), forming the activation signal processing unit 130A, are configured to generate the composite activation signal STA by individual activation elements 13nd, in response to the activation command signals S3n generated by the activation command elements 2na, and to generate individual activation signals SIG3n, directed to the main CPU, by individual buffer elements 13ns, which are, for example, NPN transistors. The main CPU is configured to perform operational control for the auxiliary electrical device 105 according to the activation command elements 2na, which are provided for corresponding activation factors.

[0032] The main CPU is configured to generate a lock-out command CNT3n1, an activation signal from command CNT3n2, a separation state release command CNT3n3, and an irregularity diagnostic command CNT3n4 to the individual activation processing units 13n, either individually or simultaneously. A detailed description of this will follow later with reference to Fig. 2A and Fig. 2B given.

[0033] A detailed description of configurations is now given, which are in Fig. Figure 2A shows a detailed circuit diagram of a general example, which is the single activation processing unit. Fig. 1 concerns, and Fig. 2B, which is a detailed circuit diagram of a specific example, that is the single activation processing unit from Fig. 1 concerns.

[0034] Fig. 2A is a configuration diagram of the single activation processing unit (Single Activation Processing Unit) 13n, which is applicable, for example, to a case where the activation command element 2na is, for example, a push button switch to perform an indefinite short period closing operation, and / or to a case where the activation command element 2na is, for example, a toggle switch to perform an indefinite long period opening / closing operation. Fig. 2B is a configuration diagram of the single activation processing unit 13n, which is suitable for the case where the indefinite long period opening / closing operation is performed.

[0035] First, in Fig. 2A, the single activation processing unit 13n, is designed to be operated using the vehicle's on-board battery voltage Vbs and the backup voltage Va. Currents flowing through four transistors, represented as PNP transistors, and one field-effect transistor (FIT) from a variety of transistors used in this case, are standby currents that also flow when the vehicle is parked.

[0036] An input element 61, which is to be supplied with energy from the vehicle's on-board battery voltage Vbs, is the PNP transistor to be operated in a conducting state by means of a base resistor 61a when a logic level of the activation command signal S3n is "L", thereby operating a first activation element 61e by means of a filter circuit 61C and a second activation element 61f by means of a series resistor 61b. An on-state stabilization resistor 61b is connected between an emitter terminal and a base terminal of the transistor.

[0037] Even if the logic level of the activation command signal S3n is "H", the input element 61 can be operated in such a way as to be closed by a forced closing element 68. The forced closing element 68 is configured to tend to be open / closed by an irregularity diagnostic command CNT3n4, which is generated by the main CPU included in the arithmetic control unit 120A.

[0038] In addition, the filter circuit 61c, which consists of a resistor and a capacitor, is used to prevent noise malfunctions of the first activation element 61e and the second activation element 61f.

[0039] A first cooperation element 62a, which is supplied with energy from the vehicle's on-board battery voltage Vbs, is operated in such a way that it is closed by the second activation element 61f, thereby causing a second cooperation element 62b to close via a cooperation resistor 62C. The second cooperation element 62b then closes the first cooperation element 62a. The result is an activation interlock unit 62 as a whole.

[0040] Furthermore, an output voltage from the first cooperation element 62A forms a composite activation signal STn and is coupled to form a logic OR via a diode, which serves as the single activation element 13n, to generate the composite activation signal STA. The output voltage is then fed to the main CPU as a single activation signal SIG3n via a single buffer element 13ns, which is an NPN transistor. The single activation signal SIG3n is connected to the stabilized voltage Vcc via a parallel resistor.

[0041] While a clear command element 63, connected between a base terminal and an emitter terminal of the second cooperation element 62b to disconnect it, is controlled to be in a conducting state by the interlock clear command CNT3n1, generated by the main CPU, thus clearing a stored state of the activation interlock unit 62. However, if the second activation element 61f is closed, the activation interlock unit 62 is configured as a set preferred type such that the closed state of the first cooperation element 62a is maintained even if the clear command element 63 is closed.

[0042] The first cooperation element 64a, which is supplied with energy from the vehicle's on-board battery voltage Vbs, is operated in such a way that it is closed by the second cooperation element 64b, thereby generating a continuous locking release signal S64. The closed state of the second cooperation element 64b is maintained via a cooperation resistor 64C. As a result, a complete locking release unit 64 is formed.

[0043] Furthermore, a pre-stage signal separation element 65a, which is to be operated in such a way that it is closed by the first cooperation element 64A, separates the second activation element 61f. A post-stage signal connection element 6b, which is to be operated in such a way that it is closed by the first cooperation element 64A, separates the second cooperation element 62b. As a result, the first cooperation element 62A is opened.

[0044] The second cooperation element 64b is configured to be powered by an activation signal isolation resistor 66A, by an activation signal isolation command CNT3n2 generated by the main CPU, and to be disconnected from the power supply by an isolation state release element 66b, by an isolation state release command CNT3n3 generated by the main CPU.

[0045] Meanwhile, an opening-determining element 67a, which is a field-effect transistor connected in parallel to the separation-state release element 66b, forms a recovery-determining unit 67. When the activation command signal S3m is generated (its logic level is L), such that the input element 61 and the first activation element 61b are closed, an electrical gate potential of the opening-determining element 67a is reduced by a closing-time separation resistor 67b, so that the opening-determining element 67a maintains the open state.

[0046] However, when the activation command signal S3n is stopped (its logic level is H), and the input element 61 and the first activation element 61e are open, the opening determination element 67a is operated in such a way that it is closed by the backup voltage Va through an opening-time operating resistor 67C. Consequently, the separation interlock unit 64 is opened and, as a result, the separation state of the activation interlock unit 62 is released.

[0047] A capacitor 67b to prevent a malfunction due to a noise voltage is connected to a gate terminal of the opening time operating resistor 67C.

[0048] A description is now given of the configuration of the single activation processing unit 138 (example n = 8), which is in Fig. 2B is shown, with a focus on differences to Fig. 2A is laid.

[0049] In Fig. 2B is a single activation signal SIG38 from an output section of the filter circuit 61C to the main CPU through a single buffer element 138s at the position of the dashed line. Fig. 2A is entered, whereas a connection position of the post-stage signal separation element 65b is connected to a connection point between a series resistor 65c added to an output circuit of the first cooperation element 62A and a single activation command element 138b.

[0050] As a result, the main CPU can always monitor the logic state of the activation command signal S38 independently of the operating state of the activation command locking unit 62.

[0051] If, for example, the activation command element 68A is a push button switch and its operating period is equal to or shorter than the period required to activate the main CPU (e.g., 0.5 seconds), the main CPU cannot determine which of the multiple activation command elements 2na has been closed, and the circuit configuration will be incorrect. Fig. 2B is suitable for a case where the activation command elements 2na perform closing and opening operations for relatively long periods.

[0052] Furthermore, the activation signal separation instruction CNT382, generated by the main CPU, is designed to operate the quenching instruction element 63 through a cooperation diode 66C.

[0053] Thus, when the upstream stage signal isolating element 65a and the downstream stage signal isolating element 65b are closed by the activation signal isolating command CNT382, the activation interlocking unit 62 is reset by the deletion command element 63 in order to open the first cooperation element 62A.

[0054] If the main CPU generates the interlock erase instruction 381 simultaneously with the generation of the activation signal disconnect instruction 382 by the main CPU, the operating circuit formed by the cooperation diode 66c is not necessary for the erase instruction element 63. (2) Detailed description of actions and operations

[0055] A detailed description will now be given of the actions and operations of the on-board vehicle electrical control device 100A, which comprises the activation signal processing unit 130A according to the first embodiment of the present invention, configured as shown in Fig. 1, Fig. 2A and Fig. 2B is shown.

[0056] First, in Fig. 1. When the power supply switch 102 is closed for vehicle operation, the power supply relay 103A is charged by the operating signal composition circuit 113 and the power supply relay operating element 112. The operating power supply voltage Vbb is thus applied by the vehicle battery 101 to the vehicle electrical control unit 100A via an output contact of the power supply relay 103A, and the stabilized voltage Vcc is applied to the main CPU forming the arithmetic control unit 120A by the stabilized power supply 110.

[0057] The vehicle battery voltage Vbs, which is the output voltage of the vehicle battery 101 itself, is also fed to the vehicle electrical control unit 100AA. The backup voltage Va is always generated by the backup power supply 114 in order to retain information stored in the RAM memory RMEM, which is the volatile memory included in the main CPU.

[0058] The main CPU, to which the stabilized voltage Vcc is applied, is configured to perform an internal inspection, which includes the non-volatile program memory PMEM and data memory DMEM, and then to cooperate with the monitoring timer WDT to generate the normal operating signal RUN, thereby performing a self-holding operation for the power supply relay 103A through the operating signal composition circuit 113 and to perform the operating control for the main electrical device 104, which is a main electrical consumer, while monitoring an operating start signal SIG0.

[0059] Furthermore, when the power supply switch 102 is opened, and thus the operating start signal SIG0 is stopped, a run-on sequence is executed, which includes memory processing to transfer information about main current values ​​contained in the RAM to the non-volatile data storage DMEM, and a runtime monitoring signal is then stopped. Consequently, the normal operating signal RUN is stopped and the power supply relay 103A is discharged to open.

[0060] However, as described above, even if the power supply switch 102 is open, when the activation signal processing unit 130A generates the composite activation signal STA, the power supply relay 103A is charged by the operating signal composite circuit 103 and the power supply relay operating element 112. Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal composite circuit 113 and the power supply relay operating element 112, even if the composite activation signal STA is stopped. When the operating control for the auxiliary electrical device 105 is completed, the auxiliary control operation is terminated by executing the predetermined stop processing to stop the normal operating signal RUN.The detailed configuration of the single activation processing unit 13n, which forms the activation signal processing unit 130A, is as above with reference to . Fig. 2A and Fig. 2B described.

[0061] A detailed description will now be provided by Fig. 3. A first example diagram of a time-flow diagram to represent an operation is given. Fig. 2A is, and Fig. 3B, which is a second example diagram of the time sequence diagram.

[0062] In Fig. 3A shows a timing diagram in row “a” in an upper section, indicating the open (off) and closed (on) states of the activation command of element 2na in the auxiliary activation command circuit 2n (n = 1 to 8). A timing diagram in row “b” in a middle section shows a waveform of a phase-smoothed input signal S61f, which is an output signal of the filter circuit 61C. A timing diagram in row “c” in the middle section shows a waveform of an activation interlock signal, indicating an operating state of the composite activation signal STA, in response to the output signal of the activation interlock unit 62, and the single activation signal SIG3n, which is a logically inverted signal thereof.

[0063] Thus, it is specified that the activation command control waveform is generated at a time delayed from an operating waveform of the activation command element 2na by a delay response period td (e.g., 5 ms), which is determined by a filter constant of the filter circuit 61C, and that the activation interlock unit 62 detects that the activation command element 2na is closed, based on the fact that a one-period width of the activation command element 2na is equal to or greater than the delay response period td. Meanwhile, a timing diagram in a row "b" in a lower section indicates a pulse signal by the interlock clear command CNT3n1, which is periodically generated by the main CPU at a predetermined clear pulse generation cycle Tb (e.g., 100 ms).

[0064] Furthermore, in the first example from Fig. Figure 3A illustrates a case where the one-period width of the activation command element 2na is equal to or longer than td + Td and shorter than td + 2Td. As a result, the composite activation signal STA is stopped at the time when the second interlock clear command CNT3n1 is generated.

[0065] Meanwhile, in the second example of Fig. Figure 3B illustrates a case where the activation instruction element 2na is not turned off even after the lock-out instruction CNT3n1 is generated, for example, N = 10 times (1 second) or more. In this case, the main CPU is trained to determine that the activation instruction element 2na has a short-circuit irregularity.

[0066] However, if the activation instruction element 2na is a toggle switch, and a closed state is thus created for a long period, the main CPU determines that the activation instruction element 2na has a contact fault, based on the fact that the activation instruction element 2na changes from On to Off while the latching erase instruction CNT3n1 is generated, for example N = 10 times (1 second) or more.

[0067] The number N described above for the determination can be suitably set to a different value according to a property of the single activation command element 2na, and each set value is held and stored in advance in the non-volatile program memory PMEM or the data memory DMEM.

[0068] A detailed description will now be provided by Fig. 4 is given, which is a third example diagram of the time sequence diagram to represent the operation from Fig. 2A is, and Fig. 4B, which is a fourth example diagram of the time sequence diagram to represent the operation from Fig. 2B is.

[0069] In Fig. 4A, from a row “a” to a row “b” in an upper section, the row “a” indicates the open / closed state of the activation command element 2na, the row “b” indicates a waveform of the dressed input signal S61f, the row “c” indicates the composite activation signal STA, and the row “b” indicates a generating state of the interlock clear command CNT3n1, as in Fig. 3A. A series “j” indicates a generation state of the single activation signal SIG3n that is the logically inverted signal of the composite activation signal STA.

[0070] Furthermore, in this example, at a time when the interlock delete command CNT3n1 has been generated 3 times, the activation signal voltage command CNT3n2, which is specified in a series "small" in a middle section, is generated by pre-stage signal separation element 65a and post-stage signal separation element 65b. Fig. 2A to operate to close, so that the composite activation signal STA in row “c” and the single activation signal SIG3n in row “j” are released, even if the activation command element 2na in row “a” is in the closed state.

[0071] The continuous interlock separation signal S64 in a series “f” in a lower section is an output signal of the separation interlock unit 64. Fig. 2A and its logical level is “H”, as a result of generating the activation signal separation instruction CNT3n2 in the previous row “e”.

[0072] A preamp smoothing input signal S61b in a series “g” in the lower section is a voltage signal immediately after the filter circuit 61C. Fig. 2A, and that the pre-stage smoothing input signal S61b is somewhat attenuated, even when the pre-stage signal separation element 65a is closed, compared to the dressed input signal S61f in series “b” in the upper section, due to a difference depending on whether the series resistor 61d is interposed or not.

[0073] Furthermore, if the activation command element 2na in the row “a” in the upper section is open (Off), the input element 61 and the first activation element 61e are off Fig. 2A are open and the opening determination element 67a of the restoration determination unit 67 changes from the open state to the closed state.

[0074] As a result, when the separation interlock unit 64 is reset to return to the normal state, and the activation command element 2na is closed (On) in a section on the right side of the row “a” in the upper section, the activation command interlock signal SIG3n is generated in the row “c”.

[0075] In Fig. 4B, that the time sequence diagram is that to Fig. 2B includes differences from the case from Fig. 4A, that the time sequence diagram is that to Fig. 2A belongs as follows.

[0076] The single activation signal SIG38 (example of n = 8) from Fig. 2B is a signal obtained by the single buffer element 138s, which logically converts the preamplifier smoothing input signal S61b to the output signal of the filter circuit 61C. An output waveform of this is obtained by taking a waveform delayed by the response delay period td through the filter circuit 61C from the waveform of the activation command element 28A in row "a" in the top section, and logically converting the delayed waveform by the single buffer element 138s, as shown in row "j" of the bottom section. Fig. 4B indicated.

[0077] Thus, the single activation signal SIG38 obtained in this state is not affected by the operating states of the activation interlock unit 62 and the separation interlock unit 64. However, the composite activation signal STA is the same as in the case of Fig. 4A.

[0078] A detailed description will now be provided by Fig. 5 is specified, which is a flowchart to represent an operation that is a main control operation means from Fig. 1 concerns, and Fig. 5B, which is a flowchart to represent an operation that uses an auxiliary control operation tool from Fig. 1. Each resource can be formed by allocated hardware (devices), a central processing unit (unit cells), or modules. The same applies below.

[0079] In Fig. Step 501, a preliminary step, is a step in which the power supply switch 102 is closed to generate the power supply switching signal PWS, or the activation signal processing unit 130A generates the composite activation signal STA. The next step, 502, also a preliminary step, is a step in which the power supply relay 103 is charged by the operating signal composite circuit 113 and the power supply relay operating element 112, the operating voltage Vbb is applied to the on-board vehicle electrical control devices 100A, and the stabilized power supply 110 supplies the stabilized voltage Vcc to the arithmetic control unit 120A.

[0080] The next step 510 is a step in which the main CPU, which forms a main section of the arithmetic control unit 120A, begins generating the runtime monitoring signal and the control operation.

[0081] Next, step 511 is a step in which the generation state of the runtime monitoring signal is monitored by the monitoring timer WDT (not shown) and, if the generation state is normal, the monitoring timer WDT generates the normal operating RUN signal.

[0082] The next step 512 is a determination step that determines whether the power supply switch 102 is closed or not, according to the operation start signal SIG0. If the power supply switch 102 is closed, a determination of "Yes" is made, and operation continues with S513, which is a step to the block. Conversely, if the power supply switch 102 is not closed, a determination of "No" is made, and operation continues with step 531. Fig. 5B continues through a connecting element A.

[0083] Step 513, as the block, is a step in which a sum check or a parity check concerning the program memory PMEM, the data memory DMEM and the RAM memory RMEM for computational processing is performed as an initial inspection, and furthermore, it is checked whether there is an irregularity that makes the vehicle unsuitable for driving.

[0084] Step 514 is a determination step in which, if an irregularity is found in step 513, as the step block, a determination "Yes" is made, and the operation continues with step 515, whereas if no irregularity is present, a determination "No" is made, and the operation continues with step 516, which is a step block.

[0085] The main CPU is configured to repeat the control operation at a cycle of, for example, 5 ms or less, between step 510 (starting the operation) and step 519 (ending the operation), as described later. The initial inspection, first performed in step 513 as the step block, requires a period of, for example, approximately 0.5 seconds.

[0086] Step 515 is a step in which a predetermined procedure, for example an irregularity notification, is performed and the operation continues with step 517 within a predetermined period.

[0087] Step 516, as the step block, is a step in which a driving / operational control for the vehicle is performed, and the operation continues with step 517 within a predetermined period.

[0088] Step 517 is a determination step in which it is determined again whether the power supply switch 102 is closed or not, in the same way as in step 512. If the power supply switch 102 is closed, a determination of "Yes" is made, and the operation proceeds to step 519 to terminate the operation, whereas if the power supply switch 102 is not closed, a determination of "No" is made, and the operation proceeds to step 520.

[0089] In step 519, which terminates the operation, other control programs are executed to return to step 510, the starting step of the operation, so that the calculation cycle is equal to or shorter than, for example, 5 ms. The series of steps from step 510 (starting the operation) to step 519 (terminating the operation) belongs to the main control operation tool 500, and step 511 of this tool belongs to the self-holding tool.

[0090] Step 520 is a step that belongs to a control-stop processing means for performing a functional inspection for the activation signal processing unit 130A, and for transferring and writing learned data written to the RAM memory during the operation of the vehicle, and important data in an irregularity occurrence recording to the non-volatile data storage DMEM or the program storage PMEM.

[0091] For the functional inspection for the activation signal processing unit 130A in step 520, the separation state release command CNT3n3, which is directed to the separation interlock unit 64, and the irregularity diagnostic command CNT3n4, which is directed to the activation command signal S3n, are used to perform a preliminary inspection for the activation signal processing unit 130A, which includes the recovery determination unit 67.

[0092] The next step 521 is a step that leads to a self-holding stopping device for stopping the runtime monitoring signal, so that the monitoring timer stops the normal operating RUN signal.

[0093] The next step, 522, is a step in which the power supply to the main CPU is stopped and the series of control operations is completed.

[0094] In Fig. 5B is step 531, a determination step in which, if the operation is from step 501 as the preliminary step from Fig. If step 5A proceeds to step 510 as the initial step, due to the generation of the composite activation signal STA, a determination "Yes" is made, and the operation continues to step 532, whereas if the operation proceeds from step 501 to step 510, due to the closing of the power supply switch 102, a determination "No" is made, and the operation exits to step 520. Fig. 5A continues. In short, the determination “Yes” step 531 is made in the state where the operating start signal SIG0 is not generated by the power supply switch 102, whereas the determination “No” step 531 is made in the state where the operating start signal SIG0 is generated.

[0095] Step 532 is a step in which the operation to the state of the single activation signal SIG3n is read, and current information on it is written and stored in a predetermined address of the RAM memory.

[0096] The next step 533 is a step that leads to an activation signal, irregularity determination means to generate tendencies, as with reference to Fig. 3B described, the interlock clear command CNT3n1 is heard a multitude of times to determine whether or not there is a short circuit irregularity or a contact fault of the activation command element 2na.

[0097] The next step 534 is a determination step in which, if an irregularity determination result obtained in step 533 is normal, a determination of "Yes" is made, and the operation continues with step 535, whereas, if the irregularity determination result is irregular, a determination of "No" is made, and the operation continues with step 520. Fig. 5A continues via a connecting element B.

[0098] Step 535 is a step that belongs to an output processing means for executing an operating control for the auxiliary electrical device 105, which includes details of the single activation signal SIG3n read out in step 532.

[0099] The next step 536 is a determination step in which an input state of a sensor, which is operated as a result of the output processing in step 535, is monitored, and, if a detection input is received, a determination “Yes” is made, and the operation continues with step 583, whereas, if the detection input cannot be received, a determination “No” is made, and the operation continues with step 537.

[0100] Step 537 is a determination step that includes a determination of whether a predetermined allowable period has elapsed or not, and, if the period has not elapsed, performs a determination of "No" to return to step 535, whereas, if the delay response period exceeds the predetermined value, a determination of "Yes" is made to proceed to step 538.

[0101] Step 538 is a step that belongs to an activation signal separation means to generate the activation signal separation command CNT3n2 to activate the separation determination unit 64 in order to stop the outputs of the activation loss of a 62 to stop the composite activation signal STA.

[0102] The series of steps from step 531 to step 538 belongs to the auxiliary tax measure 530, which leads to step 520. Fig. 5A continues through connecting element B after step 538. (3) Detailed description of a modification example

[0103] A detailed description will now be given from a configuration, an action, and an operation. Fig. Figure 6 is given, which is an overall circuit block diagram of the on-board vehicle electrical control device, which includes the activation signal processing unit, according to a modification example thereof. Fig. 1, with a focus on differences to Fig. 1.

[0104] In Fig. 6. The same reference symbols will be used as those from Fig. 1 for corresponding to Fig. 1 related sections used. In Fig. 6 comprises the on-board vehicle electrical control device 100A, which is designed to supply energy from the on-board vehicle battery 101 through the energy supply relay 103A in order to perform operational control for the main electrical device 104 and the auxiliary electrical device 105, and an activation signal processing unit 130C, which is provided between the arithmetic control unit 120A and the activation auxiliary signal group 106A.

[0105] The activation signal processing unit 130 from Fig. 1 is formed from device logic circuits, which are known as the multitude of single activation processing units 13n in Fig. 2A and Fig. 2B are shown.

[0106] However, the activation signal processing unit 130C is made of Fig. 6 is formed from a sub-CPU, which is an auxiliary microprocessor. The single activation processing unit 13n is an activation signal processing device formed by a control program using the sub-CPU.

[0107] Sections belonging to the filter circuit 61C from Fig. 2 on Fig. 2B belong, are considered an input interface circuit 160 in Fig. 6 are assembled and connected between the activation auxiliary signal group 106A and the activation signal processing unit 130C.

[0108] Furthermore, the activation signal processing unit 130C is supplied with energy from an auxiliary voltage Vc, which is generated by an auxiliary control power supply 115, which is always supplied with energy from the on-board vehicle battery voltage Vbs, and is configured to generate the composite activation signal STA when one of the activation command elements 2na (n = 1 to 8) is closed, in order to charge the power supply relay 103A through the operating signal composite circuit 113 and the power supply relay operating element 112, in order to supply the arithmetic control unit 120A through the stabilized power supply 110.

[0109] As in the case of Fig. 3, the operating signal composition circuit 113 is designed to use the power supply switching signal PWS generated by the power supply switch 102, the composite activation signal STA and the normal operating signal RUN generated by the monitoring timer WDT to charge the power supply relay 103A by the power supply relay operating element 112.

[0110] In this modification example, the sub-CPU forming the activation signal processing unit 130C has a significantly larger program memory capacity and lower overall energy consumption compared to the main CPU forming the arithmetic control unit 120A, and exhibits a short response delay period at the time of activation. The sub-CPU can therefore input directly, even if the closing signal from a push-button switch is a short period that triggers a closing operation.

[0111] As a result, the on-board vehicle electrical control device can be provided, which includes the activation signal processing unit, which has a small standby current even when power is always supplied to the sub-CPU, and is no worse than the 130A device activation signal processing unit. (4) Main point and features of the first embodiment and of the modification example thereof

[0112] As can be seen from the above description, the on-board vehicle electrical control device 100A comprises the activation signal processing unit 130A, 130C according to the first embodiment of the present invention, and the modification example of the first embodiment: An arithmetic control unit 120A, configured to execute the control program, which serves as the main control operational means 500 for starting the control operation by applying the stabilized voltage Vcc from the on-board vehicle battery 101 via the power supply relay 103A, configured to respond to the closing operation of the power supply switch 102 and the stabilized power supply 110, so that the normal operating signal RUN is generated, maintain the closing operation of the power supply relay 103A and monitor an operating control for the main electrical device 104 and the response state to the operating control, wherein the arithmetic control unit is configured to transfer and store at least part of the last current information in the non-volatile memory when the power supply switch 102 is opened, then to stop the normal operating signal RUN,and to discharge and stop the power supply relay 103A; and the activation signal processing unit 130A, 130C, configured to execute the control program serving as the auxiliary control means 530, to activate the arithmetic control unit 120A in response to closing operations of the plurality of activation command elements 21a, 22a, ..., 2na, even when the power supply switch 102 is open, and to monitor an operating control for the auxiliary electrical device 105 and the response state to the operating control.

[0113] The activation signal processing units 130A, 130C comprise the plurality of individual activation processing units 131, 132, ..., 13n, into which the activation command signals S31, S32, ..., S3n are to be entered, which react to the open state and the closed state of the activation command of the element 2na (n = 1, 2, ..., N, the same applies when standing).

[0114] Some of the multiple activation command elements 2na are configured to generate the activation command signal S3n, which is an indefinite short period, and are represented by push-button switches, and another part of them are configured to generate the activation command signal S3n, which is an indefinite long period, and are represented by toggle switches or push / pull plugs, which can be changed to a closed or open state by manual operation.

[0115] Furthermore, each of the multiple individual activation processing units 13n comprises the activation interlock unit 62, which is configured to store a generation of associated activation command signals S3n, to couple the composite activation signals STn, each of which is the output signal of the activation interlock unit, to each other to form a logical OR in order to generate the composite activation signal STA, and to generate the individual activation signal SIG3n for the individual input of a generation state of an associated activation command signal S3 to the arithmetic control unit 120A.

[0116] The arithmetic control unit 120A is configured to: start the control operations when the stabilized voltage Vcc is applied by the power supply relay 103A to be operated, to be fired, in response to the composite activation signal STA, and use the normal operating signal RUN to maintain the operating state of the power supply relay 103A; and read from the single activation signal in S EG 3 n to perform the operating control for the auxiliary electrical device 105, and generate the activation signal separation command CNT3n2 to stop the output of the activation calculation unit 62 until the generation of the normal operating signal RUN is stopped, as a result of the operation confirmation that accompanies the operating control, or the determination of a predetermined period passing.

[0117] The single activation processing unit 13n further includes the application distribution unit 64 and the recovery determination unit 67.

[0118] The separation determination unit 64 is designed to be operated by the activation signal separation command CNT3n2 and to stop the generation of the composite activation signal STn when the plurality of activation command elements 2na are in the normally closed state or the irregularly closed state.

[0119] The recovery determination unit 67 is configured to reset the separation determination unit 64 when the plurality of activation command elements 2na are in the normally open state or in the back-to-open state, and enables the generation of the composite activation signal STn when the plurality of activation command elements 2na are closed.

[0120] The set input signal of the activation locking unit 62 is the post-stage smoothing input signal S61f, which is obtained through the input element 61, to which energy is supplied in order to be operated, by the activation command signal S3n, the filter circuit 61C and the series resistor 61d.

[0121] Regardless of whether the activation instruction element 2na performs the indefinite-short-period operation or the indefinite-long-period operation, the single activation signal SIG3n is obtained by the single buffer element 13ns, which applies a logical conversion to the composite activation signal STn in order to change the system voltage.

[0122] Alternatively, if the activation command element 2na performs the indefinite-long-period operation and is suitable to stably generate the composite activation signal STn without interposing the activation interlock unit 62, the single activation signal SIG3n is obtained by the single buffer element 13ns, which applies a logic conversion to the pre-stage smoothing input signal S61b, which is the output signal of the filter circuit 61C, in order to thereby change the system voltage.

[0123] The arithmetic control unit 120A comprises, as part of the auxiliary control means 530, the activation signal irregularity determiner, which is the control program designed to generate, in a single manner or a simultaneous manner, the interlock delete command CNT3n1, which is directed to the activation command change unit 62, which is arranged for each of the plurality of single activation processing units 13n.

[0124] The activation loss of a 62 is the memory unit of a set preferred type configured to generate and store the composite activation signal STn when the activation command element 2na is closed, and to maintain the generating state of the composite activation signal STn even when the activation command element 2na is consequently open, and wherein the storage of the composite activation signal STn is reset when the interlock clear command CNT3n1 is generated, but the composite activation signal STn retains the generating state when the activation command element 2na remains closed.

[0125] Furthermore, the activation signal irregularity determiner is designed to use the single activation signal SIG3n, which is generated when the interlock delete command CNT3n1, directed to the activation loss of a 62, is generated in the meantime, to monitor the open state and the closed state of the activation command of element 2na.

[0126] If the activation command element 2na generates the indeterminate short-period closing signal and the single activation signal SIGn detects the closed state of the activation command element 2na during the period of a predetermined number of generations of the interlock clearing command CNT3n1, then the activation command element 2na is determined to have a short-circuit irregularity.

[0127] If the activation command element 2na generates an indefinite-long-period closing signal, the single activation signal SIGn detects the closed state of the activation command element 2na once, and the activation command element 2na subsequently changes from the open state during a predetermined period within the period of generating the predetermined number of times the interlocking delete command CNT3n1, the activation command element 2na is determined to have the separation irregularity.

[0128] As described above, according to a second aspect of the present invention, the arithmetic control unit is configured to generate the interlocking erase command directed to the activation loss currency unit, which is the storage unit of a preset preferred type, for a multitude of times, and to detect a short-circuit irregularity or a disconnection irregularity of the activation command element 2na, according to the logic state of the single activation signal SIG3n during the period of generation of the interlocking erase command.

[0129] Thus, the following feature is provided. The composite activation signal STn and the single activation signal SIG3n can share and use the output signal of the same activation interlock unit, and the irregularity determination period can be set according to the number of times the interlock release command is generated.

[0130] Furthermore, the following feature is provided. If the single activation signal SIG3n is received from the evaluated input signal, which is the input signal to the activation interlock unit, the open / closed state of the activation command element 2na can be monitored independently of the action state of the activation interlock unit.

[0131] The separation determination unit 64 is configured to operate, when the activation signal separation command CNT3n2 is generated, to close the pre-stage signal separation element 65A and the post-stage signal separation element 65b, which are configured to disconnect from the set input or the reset input of the activation interlock unit 62, and the composite activation signal STn, in order to thereby stop the composite activation signal STn.

[0132] The recovery determination unit 67 comprises the opening determination element 67a, which is a field-effect transistor for resetting the separation locking unit 64, and the opening determination element 67a is configured to be brought into a conducting state to be separated by the first activation element 61e, which is brought into a conducting state when the activation command signal S3n is generated, and is brought into a conducting state to be closed by applying the gate voltage through the opening-time operating resistor 67C when the activation command signal S3n is stopped, so that the first activation element 61e is opened.

[0133] The gate voltage is the backup voltage Va, which is a stabilized voltage generated by the backup power supply 114, to which energy is always supplied from the on-board vehicle battery 101.

[0134] As described above, according to a third aspect of the present invention, the separation lock state of the separation lock unit, which is configured to reset the activation command change unit that has stored the generation of the activation command signal S3n, is released by the recovery determiner, which comprises the field-effect transistor, when the activation command signal S3n is released. When the activation command signal S3n is regenerated, the activation lock unit, in the reset state, stores and retains the generation. The separation lock unit and the recovery determiner are arranged for each of the plurality of activation signal processing units.

[0135] Thus, the following feature is provided. Once a specific activation command element 2na is closed, the arithmetic control unit executes the activation processing control in response to this closure and then suspends the operation, thereby disconnecting the power supply relay and saving energy. If this specific activation command element 2na is closed intermittently or continuously, reactivation by the disconnection interlock unit is prevented, which consumes little energy. Reactivation can be performed by the specific activation command element 2na that closes again after being opened once, and even if the specific command element 2na is continuously closed, the activation processing control can be performed by another activation command element 2na at any given time.

[0136] The arithmetic control unit 120A includes the stop processing means, which is the control program to be executed when the power supply switch 102 is open, as part of the main control operation means 500, and the control stop processing means is configured to generate the separation state release command CNT3n3 and the irregularity diagnostic command CNT3n4, to perform a diagnosis for the component included in the single activation processing units 13n.

[0137] The irregularity diagnostic command CNT3n4 is designed to apply an opening and closing control, in a single manner or a simultaneous manner, in which the forced closing element 68, which is connected in parallel to the activation command element 2na, in a normal state in which the activation command element 2na does not perform the closing operation, and works together with the locking delete command CNT3n1 to monitor the behavior of the activation loss of a 62 in order to check whether a suitable single activation signal SIG3n is generated or not.

[0138] The separation state release command CNT3n3 is configured to operate, in a single or simultaneous manner, the separation state release element 66b, which is configured to reset the separation release unit 64, which is operated to be set by the activation signal separation command CNT3n2, to check the release state of the separation interlock unit 64 by using the irregularity diagnostic command CNT3n4 and the single activation signal SIG3n, and to check, based on the generation and stopping of the irregularity diagnostic command CNT3n4, whether the separation determination unit 64, which is operated to be set by the activation signal separation command CNT3n2, is to be released by the recovery determination unit 67 or not.

[0139] As described above, according to a fourth aspect of the present invention, the internal verification of the activation signal processing unit is performed immediately after the power supply switch is turned off, following the main control operation in which the power supply switch is closed.

[0140] Thus, the following feature is provided. A verification operation for the activation signal processing unit can be completed with some leeway before the auxiliary control is executed by the activation command element 2na, and an external verification concerning the activation command element 2na itself can be performed accurately, based on the normal activation signal processing unit, once the execution of the auxiliary control has started.

[0141] The activation signal processing unit 130C includes the auxiliary microprocessor SCPU, which receives power from the auxiliary control power supply 115, which is always supplied with power from the on-board vehicle battery 101 to generate the auxiliary voltage Vc.

[0142] The input interface circuit 160, which is a filter circuit, is provided between the activation auxiliary signal group 106A, which includes the plurality of auxiliary activation instruction circuits 2n and the auxiliary microprocessor SCPU.

[0143] The auxiliary microprocessor SCPU forms the plurality of single activation processing units 13n, the single activation processing units 13n contain the control program that forms the activation interlock unit 62, the separation determination unit 64 and the recovery determination unit 67, and each of the plurality of single activation processing units 13n is configured to generate the composite activation signal STn in order to charge the power supply relay 103A by using the composite activation signal STA.

[0144] Each of the multiple single activation processing units 13n is further trained to generate the single activation signal SIG3n, which is directed to each of the arithmetic control units 120A, and receives from the arithmetic control unit 120A the interlock delete command CNT3n1, the separation state release command CNT3n3 and the irregularity diagnostic command CNT3n4, which contains at least the activation signal separation command CNT3n2.

[0145] As described above, according to a fifth aspect of the present invention, the activation signal processing unit, which is placed between the activation auxiliary signal group and the arithmetic control unit, comprises the auxiliary microprocessor, which is always supplied with energy from the on-board vehicle battery.

[0146] The microprocessor that forms the arithmetic control unit has a large program memory, which results in a long activation processing time and high energy consumption. In contrast, the auxiliary microprocessor has a small program memory, which offers the advantage of a short activation processing time and low energy consumption. This also allows the control program to implement various logic circuits without relying on individual circuits.

[0147] Thus, the following feature is provided. While the auxiliary microprocessor itself can directly read a short command signal, the energy consumption does not increase, even when power is constantly supplied from the vehicle's on-board battery. Second embodiment [Detailed description of the second embodiment](1) Detailed description of the configuration

[0148] A detailed description will now be provided from a configuration. Fig. Figure 7, which is a complete circuit block diagram of an on-board vehicle electrical control device comprising an activation signal processing unit, according to a second embodiment of the present invention with a focus on differences to Fig. 1.

[0149] In Fig. 7. An on-board vehicle battery voltage Vbs is applied from the on-board vehicle battery 101 of, for example, a 12 V DC system to an on-board vehicle electrical control device 100B. An operating power supply voltage Vbb is applied by a power supply relay 103B, which is charged when the power supply switch 102 is closed. In addition, the main electrical device 104, which is controlled to operate when the power supply switch 102 is closed, is connected to the on-board vehicle electrical control device 100B.

[0150] The main electrical device 104 comprises a drive control unit, which includes an operating energy conversion circuit 210 and a cooperating motor control unit 122B. The operating energy conversion circuit 210 is a DC / AC converter for the motor 200 of the vehicle, which is supplied with energy from the on-board vehicle main battery 300 for operation. The main battery 300 is designed to generate a main power supply voltage Vbm from, for example, a DC 400V system.

[0151] The auxiliary electrical device 105, which is controlled to be operated when the power supply switch 102 is open, is further connected to the on-board vehicle electrical control device 100B.

[0152] The auxiliary electrical device 105 includes a charging control section comprising a charging energy conversion circuit 310 for the main battery 300 and the on-board vehicle battery 101 and a cooperating charging control unit 121B.

[0153] Furthermore, the on-board vehicle electrical control device 100B, the main electrical device 104, and the auxiliary electrical device 105 are integrated to form a complex electronic control device 107. The main electrical device 104 comprises the driving control unit. The auxiliary electrical device 105 comprises the charging control section.

[0154] The charging control unit 121B and the motor control unit 122B each comprise a microprocessor, each powered by a constant-voltage power supply (not shown). These constant-voltage power supplies are activated by an arithmetic control unit 120B to generate a stabilized voltage. Each microprocessor then supplies a self-holding energy supply. When the activation instruction is released by the arithmetic control unit 120B, each microprocessor performs a follow-up operation to stop the power supply.

[0155] An activation auxiliary signal group 106B, connected to an inner or an outer of the on-board vehicle electrical control device 100B, forms auxiliary activation command circuits 21 to 28 (hereinafter sometimes referred to as “2n”, and the same applies below), which are formed by mutually connecting, in series, activation command elements 21a to 28a (hereinafter sometimes referred to as “2na”) and short-to-energy current limiting resistors 21b to 28b (hereinafter sometimes referred to as “2nb”), and each configured to generate an activation command signal S3n.

[0156] Part of the activation command element 2na is configured to generate the indefinite and short activation command signal S3n and is represented by push-button switches. The other part is configured to generate the indefinite and long activation command signal S3n and is represented by toggle switches or push / pull plugs that can be changed to a closed or open state by manual operation. The short-to-energy current-limiting resistor 2nb is intended to protect against a short circuit if the activation command element 2na is in contact with a power line on its positive side.

[0157] Furthermore, the number of auxiliary activation command circuits 2n is not limited to 8 and is increased or decreased according to the size of the overall system.

[0158] The on-board vehicle electrical control device 100B mainly comprises an arithmetic control unit 120B, which includes a main CPU, which is a microprocessor, and an activation signal processing unit 130B.

[0159] As in the case of Fig. 1, is the stabilized power supply 110, which is configured to generate a stabilized voltage Vcc, for example a DC voltage of 5 V, from the operating power supply voltage Vbb, connected to the arithmetic control unit 120B. The arithmetic control unit 120B comprises a main CPU, a non-volatile program memory PMEM and a data memory DMEM, a volatile RAM RMEM and a multi-channel ADC (see Fig. 8) The main CPU operates when the power supply relay 103B is charged. The arithmetic control unit 120B is configured to work in conjunction with a monitoring timer WDT to generate a normal operating signal RUN during normal operation.

[0160] Furthermore, when the power supply switch 102 is closed, the power supply relay 103A is charged by an operating signal assembly circuit 113 and a power supply relay operating element (not shown). Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal assembly circuit 113 and the power supply relay operating element, even if the power supply switch 102 is opened. The control operation is completed by executing a predetermined halt processing to suspend the normal operating signal RUN.

[0161] The backup power supply 114, configured to generate a backup voltage Va, for example a DC voltage of 5 V from the vehicle's onboard battery voltage Vbs, is connected to the arithmetic control unit 120B. However, important information, such as learned data and irregularity occurrence frequency information, stored in RAM RMEM during main CPU operation, is transferred to and stored in non-volatile data memory PMEM immediately after the power supply switch 102 opens. Then, the normal operating signal RUN is stopped, and the power supply relay 103b is discharged. Meanwhile, when the power supply switch 102 closes, the operating start signal SIG0 is input to the main CPU via an operation start command element (not shown), as in the case of... Fig. 1, in order to execute the operational control for the main electrical device 104.

[0162] However, even if the power supply switch 102 is opened when the activation signal processing unit 130B generates a composite activation signal STB, the power supply relay 103B is charged by the operating signal composite circuit 113 and the power supply operating element (not shown). Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal composite circuit 113, even if the composite activation signal STB is stopped. When the operating control for the auxiliary electrical device 105 is completed as a result, the auxiliary control operation is terminated by performing a predetermined stop processing to stop the normal operating signal RUN.

[0163] A plurality of individual activation processing units 13n (n = 1 to 8), forming the activation signal processing unit 130B, are configured to generate the composite activation signal STB by individual activation elements (not shown) in response to the activation instruction signals S3n generated by the activation instruction elements 2na, and to generate individual activation signals SIG3m directed to the main CPU by the individual buffer elements 13ns, which are, for example, NP transistors. The main CPU is configured to perform operational control for the auxiliary electrical device 105 according to the activation instruction elements 2na, which are provided for corresponding activation factors.

[0164] The main CPU is configured to generate a lock-out command CNT3n1, an activation signal disconnect command CNT3n2, a disconnect state release command CNT3n3, and an irregularity diagnostic command CNT3n4 to the single activation processing unit 13n, either individually or simultaneously. A detailed description of this is provided above with reference to... Fig. 2A and Fig. 2B given.

[0165] A fast-charging connection element 170A and a normal-charging connection element 190 are further provided for the complex electronic control devices 107. The fast-charging connection element 170 is connected to a fast charger 109A, which is a floor-mounted device, via a first charging cable. The normal-charging connection element 190 is connected to a commercial AC power supply 109b, for example with an AC voltage of 100 V, via a second charging cable.

[0166] An auxiliary input / output unit 108, provided outside the complex electronic control devices 107, comprises an open / close command switch and an actuator for opening / closing a cover, which is provided in a window opening for connecting the first and second charging cables. When the opening is closed or opened by an electrical operation, an open / close command signal for this forms one of the activation command elements 2na and is input into the activation signal processing unit 130B.

[0167] Furthermore, a periodic activation signal generated by a battery management unit 321 while the vehicle is parked forms another of the activation command elements 2na and is input into the activation signal processing unit 130B. As a result, the arithmetic control unit 120 is periodically activated to periodically supply energy to a cell management unit 322. The cell management unit 322 transmits monitoring and diagnostic information, including ambient temperature, charging voltage, and state of charge of the main battery 300, which is a lithium-ion battery, to the arithmetic control unit 120B.

[0168] Furthermore, some of the received signals from the fast charger 109a, which are obtained from the fast charging connection element 170, or a connection detection signal of the normal charging connection element 190, a detection signal of an energy reception detection element 191 and something similar will form part of the activation command elements 2na and will be entered into the activation signal processing unit 130B.

[0169] A serial control unit 116, provided in the on-board vehicle electrical control device 100B, is configured to perform communication by using a serial signal between the arithmetic control unit 120B and the charging control unit 121B, the motor control unit 122B, the cell management unit 322 and the fast charger 109A.

[0170] A detailed description will now be provided from a configuration. Fig. Figure 8 is given, which is a detailed circuit diagram to illustrate a specific example of the single activation processing unit. Fig. 7 concerns, and Fig. 9, which is a partial detailed circuit diagram from Fig. 8 is.

[0171] In Fig. 8 is a basic configuration of the single activation processing unit 138 as above with reference to Fig. 2B described. However, a resistance value detection circuit S69 is added, which is suitable to perform a connection detection of the charging cable of the normal charging connection element 190 by the single activation processing unit and 38, and details of this are in Fig. 9 shown.

[0172] Furthermore, it is cited by way of example that the energy supply for the input element 61, the activation command control of a 62 and the separation interlock unit 64, shown in Fig. 2A, Fig. 2B and Fig. 8, the auxiliary voltage Vc can be, for example, a DC voltage of 5 V, instead of the vehicle's on-board battery voltage Vbs, and the voltage Vc is an output voltage of the auxiliary control power supply 115, which is supplied with the vehicle's on-board battery voltage Vbs, as in Fig. 7 shown.

[0173] In Fig. 9 comprises the second charging cable, which is connected to the normal charging connection element 190, a pair of AC power supply lines, a closing switch 28c, a parallel resistor 28p, and a series resistor 28s. The AC power supply lines provide charging energy. The closing switch 28C forms an auxiliary activation command circuit 28 (to which n = 8 is assigned). The parallel resistor 28p is connected in parallel to the closing switch 28C. The series resistor 28s is connected in series to a parallel circuit that forms the closing switch 28C and the parallel resistor 28p.

[0174] Meanwhile, the base resistor 61A of the input element 61 described above is connected to one end of the auxiliary activation command circuit 28 via a first backflow preventer element 69A and a current detection resistor 69b of the detection circuit 69. The other end of the auxiliary activation command circuit 28 is connected to a grounding circuit in the on-board vehicle electrical control device 100B.

[0175] Furthermore, a voltage V1 from the upstream side of the current detection resistor 69b is input as a first analog signal AD1 to a multi-channel DC converter of the arithmetic control unit 120B. A voltage V2 from a downstream side of the current detection resistor 69b is input as a second analog signal AD2 to the ADC converter of the arithmetic control unit 120B. The stabilized voltage Vc is applied to an upstream side of the current detection resistor 69b by a second backflow preventer 69C.

[0176] Furthermore, the value of a series combined resistor R28 = R28s + R28p is the sum of the resistance values ​​of R28s (series resistor 28s) and R28p (parallel resistor 28p). The values ​​of R28s and R28p are set to different values ​​corresponding to the maximum permissible charging current for the second charging cable. Simultaneously, the locking switch 28C acts as a normally closed contact, which is pressed to open when the second charging cable is connected and remains closed after the second charging cable is connected.

[0177] Then, when the input element 61 is operated to be closed as a result of the connection of the second charging cable, the composite activation signal STB is generated by the single activation processing unit and 138, which are located in Fig. Figure 8 is shown. As a result, when the arithmetic control unit 120 is activated, the main CPU calculates the value of the series combined resistor R28 or the values ​​of the individual resistor values ​​R28s and R28p, which are given by the following equations (1), (2) and (3): (V1−V2) / R69b=V2 / (R28 or R28s) Therefore, R28 or R28s=R69b×V2 / (V1−V2) R28p=R28−R28s

[0178] The resistance value R69b is that of the current detection resistor 69b, which is a known reference resistance. When the shutter switch 28C is pressed to open, the value of the series combined resistor R28 is calculated as given by equation (2). When the shutter switch 28C is normally closed, the resistance value R28s of the series resistor 28s is calculated as given by equation (2).

[0179] A combination of series resistance 28s and parallel resistance 28p, which is to be applied, is determined in advance and stored as a data table in the DMEM data memory and the PMEM program memory. When the series combined resistance value R28 or the resistance value R28s is calculated, the other values ​​from the series combined resistance value R28, the resistance value R28s, and the remaining resistance value R28p are detected, and it is possible to determine whether the shut-off switch 28C was open or closed at any given time of measurement.

[0180] If the value of the selected series combined resistor R28 or resistance value R28s of the series resistor 28s is significantly smaller than the resistance value of the base resistor 61A, the applied voltage to the auxiliary activation command circuit 28 can be increased and stabilized by applying the stabilized voltage Vcc using the second backflow preventer element 69c, thereby increasing the calculated accuracy of the resistance value. Furthermore, standby current during parking without charging can be prevented by setting the resistance value of the base resistor 61a to a high value, thus suppressing energy consumption in a state where the second charging cable remains connected. (2) Detailed description of actions and operations

[0181] A detailed description will now be given of the actions and operations of the on-board vehicle electrical control device 100B, which comprises the activation signal processing unit 130B according to the second embodiment of the present invention, as shown in Fig. 7. Pay attention to the figure Fig. 9 is trained, with a focus on differences to Fig. 1.

[0182] First, in Fig. 7. When the power supply switch 102 is closed for vehicle operation, the power supply relay 103B is charged. The operating power supply voltage Vbb from the on-board vehicle battery 101 is thus applied to the on-board vehicle electrical control device 100B via an output contact of the power supply relay 103B, and the stabilized voltage Vcc is applied to the main CPU, which forms the arithmetic control unit 120B, via the stabilized power supply 110.

[0183] The on-board vehicle battery voltage Vbs, which is the output voltage of the on-board vehicle battery 101 itself, is also input into the on-board vehicle electrical control unit 100B. The backup voltage Va is always generated by the backup power supply 114 in order to retain information stored in the RAM memory RMEM, which is the volatile memory included in the main CPU.

[0184] The main CPU, to which the stabilized voltage Vcc is applied, performs an initial inspection that includes the cooperating non-volatile program memory PMEM and data memory DMEM, and then works with the monitoring timer WDT (not shown) to generate the normal operating signal RUN. The main CPU then performs a self-hold operation for the power supply relay 103B through the operating signal composition circuit 113 and the power supply parallel operating element (not shown), and executes the operating control for the main electrical device 104 while monitoring the operation start signal SIG0 (see Fig. 1) that is entered by the power supply switch 102 via the operation start command element (not shown).

[0185] Furthermore, when the power supply switch 102 is opened and the operation start signal SIG0 is thus stopped, a run-on sequence is executed, which includes memory processing to transfer information about main current values ​​contained in the RAM memory to the non-volatile data memory DMEM, and then a runtime monitoring signal is stopped. Consequently, the normal operating signal RUN is stopped and the power supply relay 103B is discharged to open.

[0186] However, as described above, even when the power supply switch 102 is open, when the activation signal processing unit 130B generates the composite activation signal STB, the power supply relay 103B is charged by the operating signal composite circuit 113 and the power supply parallel operating element (not shown). Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal composite circuit 113, even if the composite activation signal STB is stopped. When the operating control for the auxiliary electrical device 105 is completed as a result, the auxiliary control operation is completed by performing the predetermined stop processing to stop the normal operating signal RUN.The detailed configuration of the single activation processing unit 13n, which forms the activation signal processing unit 130B, is as above with reference to . Fig. 2A and Fig. 2B or Fig. 8 described.

[0187] A detailed description will now be provided by Fig. Given 10, which is a flowchart to represent an operation that involves activation processing of Fig. 7 concerns.

[0188] Fig. 10 is a diagram that is created by combining Fig. 5A and Fig. 5B is formed, as described above, which is limited to the state in which the power supply switch 102 is open.

[0189] In Fig. Step 501A, the preparation step, is a step in which the activation signal processing unit 130B generates the composite activation signal STB, and the stabilized voltage Vcc is applied to the main CPU.

[0190] The next step, 510A, is a step where the main CPU begins generating the runtime monitoring signal and performing control operations.

[0191] The next step 511A is a step in which the generation state of the runtime monitoring signal is monitored by the monitoring timer WDT (not shown), and, if the generation state is normal, the monitoring timer WDT generates the normal operating signal RUN.

[0192] The next step 533a is a step that leads to an activation signal, irregularity determination means to generate tendencies, as with reference to Fig. 3B described, the interlock clear command CNT3n1 is heard a multitude of times to determine whether there is a short circuit irregularity or a contact fault of the activation command element 2na.

[0193] The next step 535a is a step that belongs to an output processing means for executing an operating control for the auxiliary electrical device 105, which belongs to details of the single activation signal SIG3n that is read out in step 533a.

[0194] The next step 536a is a step in which an input state of a sensor, which is enabled as a result of the output processing in step 535a, is monitored to receive a detection input, or proceeds to step 538a after a predetermined period has elapsed.

[0195] The next step 538A is a step that belongs to an activation signal linkage, to generate the activation signal disconnect command CNT3n2 to activate the disconnect interlock unit 64, thereby stopping the output of the activation interlock unit 62 to stop the composite activation signal STB.

[0196] The next step 520a is a step that belongs to a control stop processing means, to perform a function check for the activation signal processing unit 130B, and to transfer and write learned data written to RAM memory during operation of the main CPU, and important data in an irregularity occurring recording to the non-volatile data storage DMEM or the program memory PMEM.

[0197] For the functional check for the activation signal processing unit 130B in step 520a, the separation state release command CNT3n3, which is directed to the separation interlock unit 64, and the irregularity diagnostic command CNT3n4, which is directed to the activation command signal S3n, are used to perform a preliminary check for the activation signal processing unit 130B, which includes the recovery determination unit 67.

[0198] The next step 521a is a step that belongs to a self-holding stopping means, to stop the runtime monitoring signal so that the monitoring timer stops the normal operating signal RUN.

[0199] In the next step 522A, the power supply to the main CPU is stopped and the control operation, which belongs to the single activation signal SIG3n (n = 1 to 8) at this time, is terminated.

[0200] A detailed description will now be provided by Fig. 11 given, which is a detailed explanatory diagram of an operational procedure for the normal charge of Fig. 7 is.

[0201] In the later described Fig. Reference numerals are assigned to the single activation processing unit 13n by combining the case of normal charging in the first embodiment and the case of fast charging in the second embodiment, and this is sometimes indicated accordingly in the description below. Fig. 14 referred.

[0202] In Fig. 11. The processing steps in normal operation using the commercial AC power supply 109b can be roughly divided into an initial step, a first step, a second step, a third step, and a final step, in the order listed from the leftmost column. Indeterminate standby periods T1 to T4, which involve manual operation, may occur between the steps. It is therefore essential that the power supply opens relay 103B to thereby halt the main CPU during these indeterminate standby periods T1, T2, T3, and T4.

[0203] Furthermore, in each processing step, activation functions are described in the top row, details of an output processing to be performed according to the activation factors are described in a next row, factors for stopping output processing are clearly described in a lower row, and a core article is described in a bottom row.

[0204] The initial step in the leftmost column concerns the opening control of the lid, which is the opening / closing door for connecting the second charging cable. If the opening / closing operation is performed manually, or if the opening / closing operation is a remote electrical operation but local processing independent of the main CPU, this initial step can be omitted.

[0205] If the opening / closing control of the lid is carried out by the arithmetic control unit 120B, for example, a push button switch 26A is used for the lid opening command, the auxiliary activation command circuit 26 (n = 6) (see Fig. 14) connected and an activation package is only an activation command signal S36 (n = 6) which is generated by the push button switch 26A.

[0206] An output processing function based on the activation factor is used to operate a lid opening motor, in order to open the lid using the main CPU.

[0207] A halt factor for output processing is determined by an operation of a lid opening detection sensor provided for the auxiliary input / output unit 108, or by a predetermined constant set in the PMEM program memory of the main CPU.

[0208] It is necessary to consider that the second charging cable is not always immediately connected, even when the lid is open, and the length of any idle time in this case is unknown. Therefore, the main CPU is designed to pause operation when the lid is opened.

[0209] An indefinite standby period T1 between the initial step and the first step is therefore a connection standby period for the connecting element.

[0210] The first step is a processing step after the connection operation of the second charging cable, and an activation function of this is an activation command signal S38, which is generated by the auxiliary activation command circuit 28 (see Fig. 14), which in Fig. 9 is shown.

[0211] An output processing based on the activation function is used to calculate the value of the series combined resistor R8 and 20 or the resistance value R28s in the auxiliary activation instruction circuit 28 and to refer to a data table in order to obtain a limit value of an output current of the charging energy conversion circuit S310.

[0212] A halt factor of output processing is a state in which the main CPU transmits the current limit value to the load control unit 121B to capture a receive response information.

[0213] It is necessary to consider that the power supply switch for the commercial AC power supply 109b is not always on, even when the second charging cable is connected, and the length of any idle time in this case is unknown. Therefore, the main CPU is configured to halt operation when the second charging cable is connected.

[0214] Thus, an indefinite standby period T2 between the first step and the second step is an energy transfer start standby period.

[0215] If the power supply switch for the commercial AC power supply 109b has already been turned on when the second charging cable is connected, the main CPU does not pause temporarily but proceeds immediately to the second step.

[0216] The second step is a processing step in which the charging control unit 121B and the charging energy conversion circuit S310 perform charging operations directed to the main battery 300 and the on-board vehicle battery 101. An activation factor of this is an activation command signal S35, to be generated by an auxiliary activation command circuit 25 (see Fig. 14), who is trained to work in Fig. The energy reception detection element 191 shown in the illustration is to react.

[0217] Output processing based on the activation factor is used to close a charging contact element 190u (see Fig. 14) and to control the output current of the charging energy conversion circuit S310 based on the current limit value calculated in the first step.

[0218] A halt factor for output processing is originally set to occur when a load is near completion; however, in this case, the halt factor is in anticipation of a blackout occurring before the load is complete or an intentional power switch release. If such a specific event occurs, the main CPU halts the operation before the load is complete.

[0219] Thus, an indefinite standby period T3 between the second and third steps constitutes a power supply interruption or blackout period. The operation can proceed from this state to the final step, while the third step is omitted.

[0220] If the power supply is interrupted during charging, the second charging cable can be disconnected by pressing a push button designed to open the locking switch 28C, thus detecting a change in the connection detection resistance and opening the charging contact element 190u. If charging is to be restarted from this state, the operation proceeds from the first step to the third step. If charging is to be stopped, the operation proceeds to the termination step.

[0221] The third step is a processing step in which a remaining charging operation is performed when the charging voltage is detected again, and an activation factor is the activation command signal S35, which is the same as in the second step.

[0222] Output processing based on the activation factor is used to close the charging contact element 190u (see Fig. 14) again, and to control the output current of the charging energy conversion circuit S310 based on the current limit value calculated in the first step.

[0223] A halting factor for output processing is a charge completion signal generated by the charge control unit 121b. The main CPU continues the operation during charging and performs serial communication of charge progress information to / from the charge control unit 121b.

[0224] Thus, an indefinite standby period T4 between the third step and the fourth step is a separation standby period for the second charging cable, and the second charging cable cannot always be disconnected immediately after charging is complete.

[0225] The final step involves controlling the lid closure after the second charging cable is disconnected in a separate step (not shown). If the opening / closing operation is performed manually, or if it is a remote electrical operation but local processing independent of the main CPU, the final step can be omitted.

[0226] If the opening / closing control for the day is carried out by the arithmetic control unit 120B, for example, a push-button switch 27A for the lid closing command is connected to the auxiliary activation command circuit 27 (n = 7) (see Fig. 14) connected and an activation factor is an activation command signal S37 (n = 7) which is generated by the push button switch 27A.

[0227] An output processing function based on the activation factor is used to operate a motor for closing the lid, in order to be closed, by using the main CPU.

[0228] A halt factor for output processing is determined by an operation of a lid closing detection sensor provided in the auxiliary input / output unit 108; however, the disconnection of the second charging cable is checked simultaneously. (3) Key point and features of the second embodiment

[0229] As is evident from the above description, the on-board vehicle electrical control devices 100B, which include the activation signal processing unit 130B, according to the second embodiment of the present invention, comprise: the arithmetic control unit 120B, configured to execute the control program that serves as the main control operating means 500, to start the control operation by applying the stabilized voltage Vcc from the on-board vehicle battery 101 via the power supply control element 103B, which is configured to respond to the closing operation of the power supply switch 102, and the stabilized power supply 110, so that the normal operating signal RUN is generated, maintaining the closing operation of the power supply relay 103B, and monitoring an operating control for the main electrical device 104 and the response state to the operating control, wherein the arithmetic control unit is configuredto transfer and store at least part of the last current information in the non-volatile memory when the power supply switch 102 is opened, then to stop the normal operating signal RUN and to discharge and stop the power supply relay 103B; and wherein the activation signal processing unit 130B is configured to execute that control program which serves as the auxiliary control means 530, to activate the arithmetic control unit 120B, in response to closing operations of the plurality of activation command elements 21a, 22a, ..., 2na, even when the power supply switch 102 is open, and to monitor an operating control for the auxiliary electrical device 105, and the response state to the operating control.

[0230] The activation signal processing unit 130B comprises the plurality of individual activation processing units 131, 132, ..., 13n, into which the activation command signals S31, S32, ..., S3 are to be entered, which react to the open state and the closed state of the activation command elements 2na respectively (n = 1, 2, ..., N, the same applies below).

[0231] Some of the multiple activation command elements 2na are configured to generate the activation command signal S3n, which is an indefinite and short period, and are represented by push-button switches, and other parts are configured to generate the activation command signal S3n, which is an indefinite and long period, and are represented by a toggle switch or push / pull plug, which can be changed to a closed or open state by a manual operation.

[0232] Furthermore, each of the multiple individual activation processing units 13n includes the activation loss unit 62, which is configured to store a generation of an associated activation instruction signal S3n, to couple the composite activation signal STn, each of which is the output signal from the activation interlock unit, together to form a logical OR in order to thereby generate the composite activation signal STB, and to generate the individual activation signal SIG3n, for a single input of a generation state of an associated activation instruction signal S3n to each of the arithmetic control unit 120B.

[0233] The arithmetic control unit 120B is configured to: start the control operation when the stabilized voltage Vcc is applied by the power supply relay 103B to be operated, to be closed, in response to the composite activation signal STB, and to use the normal operating signal RUN to maintain the operating state of the power supply relay 103B; and to read the individual activation signal SIG3n to perform the operating control for the auxiliary electrical device 105, and to generate the activation signal disconnect commands CNT3n2, to stop the output of the activation command interlock unit 62 until the generation of the normal operating signal RUN is stopped, as a result of the operation confirmation that accompanies the operating control, or the determination of a predetermined period passing.

[0234] The single activation processing unit 13n further comprises the separation interlock unit 64 and the recovery determination unit 67.

[0235] The separation interlock unit 64 is configured to be operated by the activation signal separation command CNT3n2 and to stop the generation of the composite activation signal STn when the plurality of activation command elements 2na are in the normally closed state or the irregularly closed state.

[0236] The recovery determination unit 67 is configured to reset the separation determination unit 64 when the plurality of activation command elements 2na are in the normally open state or in the back-to-open state, and to enable the generation of the composite activation signal STn when the plurality of activation command elements 2na are closed.

[0237] In the on-board vehicle electrical control devices 100B, the main electrical device 104, which includes the motor control unit 122 for the motor to drive 200, to which energy is to be supplied in order to be operated by the on-board vehicle main battery 300 and the operating energy conversion circuit 210, and the auxiliary electrical device 105, which includes the charging control unit 121B for the main battery 300 and the on-board vehicle battery 101 and the charging energy conversion circuit 310, are combined in such a way as to form the complex electronic control devices 107 for an electric vehicle.

[0238] The complex electronic control devices 107 include the normal charging connection element 190, in which an alternating current voltage is to be applied from the commercial alternating current power supply 109b of a general household through the second charging cable.

[0239] The eighth activation command signal S38 for detecting the connection state of the normal charging connection element 190 is input to the activation signal processing unit 130B as the activation command signals S3n, and the fifth activation command signal S35 for detecting the energy reception state of the power supply connection of the normal charging connection element 190 is input in order to generate the composite activation signal STB.

[0240] Furthermore, when the eighth activation command signal S38 detects the connection state of the normal charging connection element 190 and the fifth activation command signal S35 detects the energy receiving state of the normal charging connection element 190, the arithmetic control units 120B apply a charging control to the main battery 300 and the vehicle battery 101 by the charging control unit 121B, even if the power supply switch 102 is in the open state.

[0241] The activation signal processing unit 130B is configured to stop the power supply to each of the arithmetic control units 120B when the normal charging connection element 190 is not in the energy receiving state, even if the connection state of the normal charging connection element 190 is detected, and to start the power supply to each arithmetic control unit 120B when the normal charging connection element 190 is determined to be in the energy receiving state.

[0242] As described above, according to a sixth aspect of the present invention, the on-board vehicle electrical control device forms the complex electronic control device configured to perform the operational control of the motor for driving the electric vehicle, and the charging control of the main battery for motor operation and the on-board vehicle battery, which is installed as the auxiliary battery, for control purposes. The functions are distributed such that when the power supply switch is closed, the operational control is performed, and when the power supply switch is open, the charging control is performed.

[0243] Charging the on-board vehicle battery for control purposes from the main battery can be carried out while the power supply switch is closed, as an exception.

[0244] Thus, the following feature is provided. During the indefinite standby period from the connection of the charging cable until the start of the previously established ground power supply, during the indefinite standby period caused by a blackout or a temporary interruption of the power supply that occurs during charging, and during the indefinite standby period from the disconnection of the charging cable until the closing of the cover, the power supply to the arithmetic control unit is stopped in order to prevent the waste of energy consumption in the non-charging state.

[0245] The sixth activation command signal S36, which is the lid opening command for the lid that opens and closes the door to cover the entire normal loading connection element 190, and the seventh activation command signal S37, which is the lid closing command for the lid, are entered into the activation signal processing unit 130B as the activation command signals S3n in order to generate the composite activation signal STB.

[0246] The auxiliary input / output unit 108, which includes the opening / closing operating device for the lid and the detection sensor for the open and closed states of the lid, is connected to the arithmetic control unit 120B.

[0247] The arithmetic control unit 120B is further designed to generate a control output directed to the open / close operating device while maintaining the operational state of the power supply relay 103B, which is activated by the generation of the sixth activation command signal S36 or the seventh activation command signal S37, and to complete the control operation in response to the state of the detection sensor, thereby performing a predetermined stop processing such that each power supply relay 103B is discharged.

[0248] As described above, according to a seventh aspect of the present invention, the activation signal processing unit for the arithmetic control unit is configured to input the sixth activation command signal S36 and the seventh activation command signal S37, which relates to the opening / closing operation of the lid, which is performed in the pre-stage of the charging start and the post-stage of the charging completion of the batteries of the electric vehicle, in order to perform the opening / closing operation for the lid by using the auxiliary input / output unit.

[0249] Thus, the following feature is provided. During the indeterminate standby periods before the connection of the connecting element and the start of the charging operation after the cover is opened, and during the indeterminate standby period after the completion of charging until the disconnection of the connecting element, the power supply to the arithmetic control unit is stopped in order to prevent the occurrence of wasteful energy consumption in the non-charging state.

[0250] The same applies to a third embodiment of the present invention.

[0251] The fourth activation command signal S34, which is a periodic pulse signal generated by the battery management unit 321, is entered into the activation signal processing unit 130B as the activation command signal S3n in order to generate the composite activation signal STB.

[0252] The arithmetic control unit 120B is configured to be periodically activated by the fourth activation command signal S34 in order to periodically supply energy to a cell management unit 322, and the cell management unit 322 is configured to transmit monitoring and diagnostic information, which includes the ambient temperature, the charging voltage and the state of charge of the main battery 300, which is the lithium-ion battery, to the arithmetic control unit 120B.

[0253] As described above, according to an eighth aspect of the present invention, the fourth activation command signal S34, which is the periodically generated pulse signal, is input into the activation signal processing unit for the arithmetic control unit. As a result, energy is periodically supplied to the arithmetic control unit and the cell management unit, and monitoring and diagnostic information about the main battery is transmitted to the arithmetic control unit.

[0254] Thus, the following feature is provided. The arithmetic control unit and the cell management unit are designed to be periodically activated for a short period by the battery management unit, which is a periodic wake-up activation file that consumes little energy, thus preventing continuous energy consumption.

[0255] The same applies to the third embodiment.

[0256] The resistance circuit formed from the locking switch 28C, which is configured to be pressed to open and close when the charging gun is inserted and removed, the parallel resistor 28p connected to the locking switch, and the series resistor 28s connected in series with the parallel circuit comprising the locking switch 28C and the parallel resistor 28p, is connected to the connector provided on the side of the second charging cable for connection to the normal charging connection element 190, thereby forming the auxiliary activation command circuit 28, which is configured to generate the eighth activation command signal S38 directed to the activation signal processing unit 130B.

[0257] The value of the series combined resistor R28 = R28s + R28p, which is the sum of the resistance value R28s of the series resistor 28s and the resistance value R28p of the parallel register 28p and the value of the resistance value R28s, changes according to the value of the maximum charging current allowed for the second charging cable.

[0258] The input element 61, a transistor into which a current is supplied to operate, is driven by the eighth activation command signal S38 to generate the set input signal for the activation interlock unit 62. It is driven into a conducting state by the series circuit comprising the base resistor 61a, the first reverse-fault inhibitor 69a, the current-sensing resistor 69b, and the series combined resistor R28. Furthermore, the voltage V1 of the upstream side and the voltage V2 of the downstream side of the star reference resistor 69b, which is the resistance value of the current-sensing resistor 69b, are each fed as the first analog signal AD1 and the second analog signal AD2 into the multichannel analog-to-digital converter (ADC) arranged for the arithmetic control unit 120B.

[0259] The activation signal processing unit 120B is configured to generate the composite activation signal STB in response to the closing of the input element 61. The arithmetic control unit 120B uses the following equation (1) and equation (2) to calculate the series combined resistance R28 or the resistance value R28s of the series resistor 28s when the arithmetic control unit 130B is activated. The conversion data pre-stored in a conversion data memory is used to set the maximum charging current for the charging control unit 121B, and detected resistance values ​​during a conversion vary according to the open and closed states of the locking switch 28C. (V1−V2) / R69b=V2 / (R28 or R28s) Therefore, R28 or R28s=R69b×V2 / (V1−V2)

[0260] As described above, according to a ninth aspect of the present invention, the resistor circuit, which serves as the auxiliary activation command circuit, is provided for the second charging cable that is connected to the normal charging connection element, and generates the eighth activation command signal S38 when the second charging cable is connected in order to activate the arithmetic control unit by means of the activation signal processing unit.

[0261] Furthermore, the activated arithmetic control unit is designed to calculate the value of the series combined resistor R28 or the resistance value R28s of the series resistor in the second charging cable in order to limit the maximum value of the charging current by the charging control unit.

[0262] Thus, the following feature is provided. The value of the series combined resistor R28 or the resistance value R28s of the series resistor is accurately measured by the multi-channel A / D converter after the arithmetic control unit is activated. Therefore, different values ​​can be set for the resistance values ​​of the series combined resistor R28 or the resistance value R28s, and the set value of the common maximum charging current can be read from the data table, regardless of whether the locking switch is open or closed.

[0263] Furthermore, the following feature is provided. The resistance value of the base resistor, the current detection resistor, or the series / parallel resistor is set high during the indeterminate charging standby periods when the second charging cable is connected and the device is in a non-charging state. As a result, it is possible to prevent current flowing into the input element, thereby preventing current consumption during charging standby periods.

[0264] In a first case, where the parallel resistance in the cable is set high and the parallel resistance is manually closed by the shut-off switch when the charging connection element is attached, the base current of the input element can be secured in the attached state and at the same time the consumed current in the charging standby period can be further prevented.

[0265] Meanwhile, in a second case where the locking switch is designed to open when the charging connection element is attached, the locking switch closes normally, thus providing the advantage of minimizing contact faults. However, the current consumed in the charging standby state increases, and therefore it is preferable to set the resistance value R28s of the series resistor high and the resistance value R28p of the parallel resistor low.

[0266] In any of the cases, the following feature is provided. If the series combined resistance R28 or the individual resistance values ​​R28s and R28p are determined, the remaining resistance values ​​can be determined by appropriately adjusting the combination of the individual resistance value R28s and the resistance value R28p. Third embodiment [Detailed description of the third embodiment](1) Detailed description of the configuration

[0267] A detailed description will now be provided from configurations. Fig. 12, which is an overall circuit block diagram of an on-board vehicle electrical control device comprising an activation signal processing unit, according to the third embodiment of the present invention, and Fig. 13, which is an overall circuit diagram showing the activation signal processing unit from Fig. 12 concerns, with a focus on differences to Fig. 1.

[0268] In Fig. A vehicle battery voltage Vbs is applied from the vehicle battery 101, for example, a 12 V DC system, to a vehicle electrical control device 100C. An operating power supply voltage Vbb is applied via a power supply relay 103C, which is charged when the power supply switch 102 is closed. Furthermore, the main electrical device 104, which is controlled to operate when the power supply switch 102 is closed, is connected to the vehicle electrical control device 100C.

[0269] The main electrical device 104 comprises a drive control unit, including an operating energy conversion circuit 210 and a cooperating motor control unit 122C. The operating energy conversion circuit 210 is a DC / AC converter for the vehicle's drive motor 200, which is supplied with energy from the vehicle's main battery 300. The main battery 300 is designed to generate an energy supply voltage Vbm of, for example, a 400 V DC system.

[0270] The auxiliary electrical device 105, which is controlled to be operated when the power supply switch 102 is open, is further connected to the on-board vehicle electrical control device 100C.

[0271] The auxiliary electrical device 105 includes a charging control section comprising a charging energy conversion circuit 310 for the main battery 300 and the on-board vehicle battery 101, and a cooperating charging control unit 121C.

[0272] Furthermore, the on-board vehicle electrical control device 100 C, the main electrical device 104 (driving control unit) and the auxiliary electrical device 105 (charging control section) are integrated to form the complex electronic control devices 107.

[0273] An activation auxiliary signal group 106C, connected to an inner or an outer of the on-board vehicle electrical control device 100C, is formed from auxiliary activation command circuits 21 to 28 (hereinafter sometimes referred to as “2n”), which are formed by mutually connecting in series activation command elements 21a to 28a (hereinafter sometimes referred to as “2na”) and short-to-energy current limiting resistors 21b to 28b (hereinafter sometimes referred to as “2nb”), and each is configured to generate an activation command signal S3n.

[0274] Part of the activation command elements 2na is configured to generate the indefinite and short activation command signal S3n and is represented by push-button switches. The other part is configured to generate the indefinite and long activation command signal S3n and is represented by toggle switches or push / pull plugs, which can be changed to a closed or open state by manual operation. The short-to-energy current-limiting resistor 2nb is intended to protect against a short circuit if the activation command element 2na is in contact with a power line on its positive side.

[0275] Furthermore, the number of auxiliary activation command circuits 2n is not limited to 8 and is increased or decreased according to the size of the overall system.

[0276] The on-board vehicle electrical control device 100C mainly comprises an arithmetic control unit 120C, which includes a main CPU, which is a microprocessor, and an activation signal processing unit 130C.

[0277] Thus, the activation signal processing unit 130C can be used by employing the methods described above. Fig. The 6 shown sub-CPU is formed in place of the activation signal processing unit 130A, which consists of the device logic circuit. Fig. 1 is formed.

[0278] As in the case of Fig. 1 is the stabilized power supply 110, which is configured to generate a stabilized voltage Vcc, for example DC 5 V, from the operating power supply voltage Vbb, connected to the arithmetic control unit 120C. The arithmetic control unit 120C comprises a main CPU, a non-volatile program memory PMEM and a data memory DMEM, a volatile RAM RMEM and a multi-channel ADC (see Fig. 13) The main CPU operates when the power supply relay 103C is charged. The arithmetic control unit 120C is configured to work in conjunction with a monitoring timer WDT to generate a normal operating signal RUN during normal operation.

[0279] Furthermore, when the power supply switch 102 is closed, the power supply relay 103C is charged by a power supply relay operating element 111 (see Fig. 13) Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal assembly circuit 113 and the power supply relay operating element 111, even if the power supply switch 102 is open. The control operation is completed by executing a predetermined halt processing to stop the normal operating signal RUN.

[0280] The backup power supply 114, configured to generate a backup voltage Va, for example DC 5 V, from the vehicle's onboard battery voltage Vbs, is connected to the arithmetic control unit 120C. However, critical information, such as learned data or information about an irregularity, stored in RAM RM EM during main CPU operation, is transferred and stored in non-volatile data memory DRM EM during a run-up period immediately after the power supply switch 102 opens. Then, the normal operating signal RUN is stopped, and the power supply relay 103C is discharged.

[0281] Meanwhile, when the power supply switch 102 is closed, the operating start signal SIG0 is input into the main CPU by an operation start instruction element 111s, which is later used with reference to Fig. 13 is described in order to carry out the operational control for the main electrical device 104.

[0282] However, even if the power supply switch 102 is open, when the activation signal processing unit 130C generates a composite activation signal STC, the power supply relay 103C is charged by the operating signal composite circuit 113 and the power supply relay operating element 111. Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal composite circuit 113, even if the composite activation signal STC is stopped. When the operating control for the auxiliary electrical device 105 is completed, the auxiliary control operation is terminated by performing a predetermined stop processing to stop the normal operating signal RUN.

[0283] In Fig. 13 comprises the on-board vehicle electrical control device 100 C, which is configured to be supplied with energy from the on-board vehicle battery 101 through the non-contact type power supply relay 103C, formed from a field-effect transistor, and the stabilized power supply 110, in order to perform operational control for the main electrical device 104 and the auxiliary electrical device 105, as shown in Fig. 12, the activation signal processing unit 130C, which is provided between the arithmetic control unit 120C and the activation auxiliary signal group 106C.

[0284] While the activation signal processing unit 130 from Fig. 1 from the in Fig. 2A or Fig. The device logic circuit shown in 2B is formed as the plurality of individual activation processing units 13n, the activation signal processing unit 130C is made up of Fig. 13 formed from a sub-CPU which is an auxiliary microprocessor, and the single activation processing units 13ns are activation signal processing means formed by a control program using the sub-CPU.

[0285] Furthermore, the power supply relay 103C is installed in the on-board vehicle electrical control unit 100C.

[0286] Further sections are those relating to the filter circuit 61C from Fig. 2A and Fig. 2B belong as an input interface circuit 160 in Fig. 13 are mounted and are connected between the activation auxiliary signal group 106C and the activation signal processing unit 130C.

[0287] Furthermore, the activation signal processing unit 130C is supplied with energy from the backup voltage Va, which is generated by the backup power supply 114, which is always supplied with energy from the on-board vehicle battery voltage Vbs, and is configured to generate the composite activation signal STC when one of the activation command elements 2na (on n = 1 to 8) is closed, in order to charge the power supply relay 103C through the operating signal composite circuit 113 and the power supply relay operating element 111, in order to supply energy to the arithmetic control unit 120C through the stabilized power supply 110.

[0288] The backup voltage Va is also supplied to the arithmetic control unit 120C to perform a blackout hold operation for the RAM memory RMEM.

[0289] The power supply relay operating element 111 and the operating signal composition circuit 113 are configured to charge the power supply relay 103C according to the power supply switching signal PWS through the power supply switch 102, the composite activation signal STC and the normal operating signal RUN generated by the monitoring timer WDT.

[0290] In the third embodiment, the sub-CPU, which forms the activation signal processing unit 130C, has a significantly smaller program memory capacity and lower overall power consumption compared to the main CPU, which forms the arithmetic control unit 120C, and exhibits a short response delay at the time of activation. The sub-CPU can thus directly input the closing signal from a push-button switch, executing a closing operation in a short period. As a result, the on-board vehicle electrical control device, which includes the activation signal processing unit, can be provided with low standby current, even when power is continuously supplied to the sub-CPU, and is no less efficient than the device activation signal processing unit 130A in the first embodiment.

[0291] A detailed description will be provided by Fig. 14 are given, which are an overall connection diagram to represent an example of an activation command signal from Fig. 12 in the second embodiment and Fig. 7 in the first embodiment.

[0292] In Fig. 14 is the arithmetic control unit 120C (120B), which is a main element of the complex electronic control devices 107, configured to cooperate with the activation signal processing unit 130C (130B) to monitor and control the auxiliary electrical device 105 (charging control section), which includes a charging control unit 121C (121B) and the charging energy conversion circuit 310, and the main electrical device 104 (driving control unit), which includes a motor control unit 122C (122B) and the operating energy conversion circuit 210. The auxiliary input / output unit 108, which relates to the opening / closing control for the cover, is connected outside of the complex electronic control devices 107.

[0294] In addition, auxiliary activation command circuits 2n (n = 3 for an unused auxiliary circuit from n = 1 to 8), which are assigned as described later, are connected to the activation signal processing unit 130C (130B).

[0295] From the auxiliary activation command circuits 2n, the auxiliary activation command circuit 26 is formed to generate the activation command signal S36, which serves as the lid opening command; the auxiliary activation command circuit 27 is formed to generate the activation command signal S37, which serves as the lid closing command; and the auxiliary activation command circuit 24 is formed to generate the activation command signal S34, which is the periodic command signal generated by the battery management unit 321.

[0307] A detailed description will now be given of the actions and operations of the on-board vehicle electrical control device 100C, which comprises the activation signal processing unit 130C according to the third embodiment of the present invention, as described in Fig. 12 is trained, with a focus on differences of Fig. 1.

[0308] First, in Fig. 12, Fig. 13 and Fig. 14, when the power supply switch 102 is closed for vehicle operation, that the power supply relay 103C is charged by the power supply relay operating element 111 (see Fig. 13) The operating power supply voltage Vbb is thus applied from the on-board vehicle battery 101 to the on-board vehicle electrical control device 100C, and the stabilized voltage Vcc is applied to the main CPU, which forms the arithmetic control unit 120C, through the stabilized power supply 110.

[0309] The 103C power supply relay is a transistor type that is installed in the 100C on-board vehicle electrical control unit.

[0310] Furthermore, the vehicle battery voltage Vbs, which is the output voltage of the vehicle battery 101 itself, is also input into the vehicle electrical control unit 100C. The backup voltage Va is always generated by the backup power supply 114 to retain information stored in the RAM memory, which is the volatile memory of the main CPU, and supplies power to the sub-CPU that forms the activation signal processing unit 130C.

[0311] The main CPU, to which the stabilized voltage Vcc is applied, performs an internal check that includes the interaction of a non-volatile program memory PMEM and data memory DMEM, and then works with the monitoring timer WDT to generate the normal operating signal RUN. The main CPU then performs a self-holding operation for the power supply relay 130C through the operating signal composition circuit 113 and the power supply relay operating element 111 (see Fig. 13) and executes the operational control for the main electrical device 104 while monitoring the operation start signal SIG0 (see Fig. 13), which is entered by the power supply switch 102 through the operation start command element 111s (see Fig. 13).

[0312] Furthermore, when the power supply switch 102 is opened, and thus the operation start signal SIG0 is stopped, a run-on sequence is executed. This sequence includes memory processing to transfer information about main current values ​​stored in the program memory to the non-volatile data memory DMEM, and a runtime monitoring signal is then stopped. Consequently, the normal operating signal RUN is stopped, and the power supply relay 103C is discharged to open.

[0313] However, as described above, even if the power supply switch 102 is opened, when the activation signal processing unit 130C generates the composite activation signal STC, the power supply relay 103C is charged by the operating signal composite circuit 113 and the power supply relay operating element 111 (see Fig. 13) Consequently, when the main CPU is activated and the normal operating signal RUN is generated, the operation of the main CPU continues through the operating signal composition circuit 113, even if the composite activation signal STC is stopped. When the operating control for the auxiliary electrical device 105 is completed as a result, the auxiliary control operation is completed by performing the predetermined stop processing to stop the normal operating signal RUN. The detailed configuration of the single activation processing unit 13n, which forms the activation signal processing unit 130C, is as described above, with reference to Fig. 2A and Fig. 2B or Fig. 8.

[0314] Furthermore, a flowchart is used to represent an operation that involves activation processing. Fig. 12 concerns, as in Fig. 10 shown.

[0315] A detailed description will now be provided by Fig. 15 given, which is a detailed explanatory diagram of an operational procedure for the fast loading of Fig. 12 is.

[0316] In Fig. The processing steps in the fast charging process using the 109A fast charger can be roughly divided into an initial step, a first step, a second step, a third step, and a final step, in the order listed from the leftmost column. Indeterminate standby periods T1 to T4, which involve manual operation, may occur between these steps. It is therefore essential that the power source opens relay 103C to thereby halt the main CPU during these indeterminate standby periods T1, T2, T3, and T4.

[0317] Furthermore, in each processing step, activation factors are described in the top row, details of an output processing to be carried out are described in a next row according to the activation factors, factors for stopping the output processing are clearly described in a lower row, and a relevant main article is described in a bottom row.

[0318] The initial step in the leftmost column concerns the opening control for the lid, specifically the opening / closing door for connecting the first charging cable. If the opening / closing operation is performed manually, or if it is a remote electrical operation but processed locally, independent of the main CPU, this initial step can be omitted.

[0319] If the opening / closing control for the lid is performed by the arithmetic control unit 120C, for example a push-button switch 26A for the lid opening is missing is connected to the auxiliary activation command circuit 26 (n = 6) (see Fig. 14) and is an activation factor an activation command signal S36 (n = 6) which is generated by the push button switch of the sixth 20A.

[0320] Output processing based on the activation time is used to operate a lid opening motor, in order to open the lid, by using the main CPU.

[0321] A halt factor for output processing is determined by an operation of a lid opening detection sensor provided for the auxiliary input / output unit 108, or a predetermined time constant set in the PMEM program memory of the main CPU.

[0322] It is necessary to note that the first charging cable is not always immediately connected, even when the lid is opened, and the length of any idle time that occurs in this case is unknown. Therefore, the main CPU is trained to pause operation when the lid is opened.

[0323] An indefinite standby period T1 between the initial step and the first step is thus a connection standby period for the connecting element, as in the case of Fig. 11.

[0324] The first step is a pre-processing step in which charging control specifications are mutually checked between the 109A fast charger and the 120C arithmetic control unit. One activation factor of this is the activation command signal S31, which is generated by the Fig. The auxiliary activation command circuit 21 shown in Figure 14 is to be generated. The charging start / stop command "f", which is generated by the fast charger 109A, is applied as this signal and is thus accepted as a communication start command "f" to start the serial communication.

[0325] An output processing based on this activation factor is used to serially transmit, for example, the maximum charging current and a required charging period, which is set on a display panel (not shown), if the charging specifications for the main battery 300 are sent to the fast charger 109A by the serial control unit 116 and to use the control output signal CNT40 to generate the charging approval signal “k” in response to the approval by the fast charger 109A.

[0326] A halting factor for output processing is the lapse of a predetermined period after the generation of the charging authorization certificate “k” or the reception of the charging start signal “g” from the fast charger 109A by the auxiliary activation command circuit 22.

[0327] It is necessary to pay attention to the fact that, even if the connection of the first charging cable is completed, the power supply switch of the 109A fast charger is closed, and the predetermined communication is carried out, if the charging specifications are not compatible, the main CPU will stop the operation if such a condition is confirmed.

[0328] Thus, an indefinite standby period T2 between the first step and the second step is an energy transfer start standby period.

[0329] If the loading start signal “g” is received immediately, the main CPU does not pause temporarily and can proceed directly to the second step.

[0330] The second step is a processing step in which the charging control unit 121C and the charging energy conversion circuit 310 perform charging operations directed to the main battery 300 and the on-board vehicle battery 101. One activation factor of this is an activation command signal S32, which is to be generated by the auxiliary activation command circuit 22 (see Fig. 14).

[0331] Output processing based on the activation factor is used to close the charging contact element 170u (see Fig. 14) and to transmit current values ​​of the charging current and charging voltage, measured by the charging energy conversion circuit 310, to the fast charger 109A via the serial signal lines.

[0332] A halt factor for output processing is originally a load completion signal; however, in this case, the halt factor is determined in anticipation of a blackout occurring before load completion or an intended release of the power supply switch. If such a specific case occurs, the main CPU halts the operation before load completion.

[0333] Thus, an indefinite standby period T3 between the second and third steps constitutes a power supply interruption or blackout period. The operation can proceed from this state to the completion state, skipping the third step.

[0334] The third step is a processing step in which a remaining load operation is performed when the activation command signal S32 is detected again, and an activation factor is the activation command signal S32, which is the same as the one in the second step.

[0335] Output processing based on the activation factor is used to close the charging contact element 170u (see Fig. 14) again, and to transmit current values ​​of the charging current and charging voltage, measured by the charging energy conversion circuit 310, to the fast charger 109A via the series signal lines.

[0336] A halt factor for the output processing unit state in which the activation command signals S31 and S32, which serve as the charging start signals “f” and “g” of the fast charger 109A, are halted, and the arithmetic control unit 120C halts the control output signal CNT40, which serves as the charging allow signal “k”.

[0337] Thus, an indefinite standby period T4 between the third step and the final step represents a separation standby period for the first charging cable, and the first charging cable cannot always be disconnected immediately after charging is completed.

[0338] The closing step involves controlling the lid after the first charging cable is disconnected (not shown). If the opening / closing operation is performed manually, or if the opening / closing operation is a remote electrical operation but local processing independent of the main CPU, the closing step can be omitted.

[0339] If the opening / closing control for the lid is performed by the arithmetic control unit 120C, for example a push-button switch 27A for the lid closing command is bound to the auxiliary activation command circuit 27 (n = 7) (see Fig. 14) and an activation factor is an activation command signal S37 (n = 7) generated by the push button switch 27A.

[0340] An output processing function based on the activation factor is used to operate a motor for closing the lid, in order to be closed, by using the main CPU.

[0341] A halting factor for output processing is determined by an operation of a lid closing detection sensor, which is provided in the auxiliary input / output unit 108; however, the disconnection of the first charging cable is checked simultaneously.

[0342] The disconnection confirmation for the first charging cable is checked according to a halt of the connection element connection confirmation signal “h”, which is received by the connection confirmation signal receiver element 41.

[0343] In the description above, the activation signal processing unit 130B in the second embodiment, as in the activation signal processing unit 130A in the first embodiment, consists of the following: Fig. 2A and Fig. 2B or Fig. The device logic shown in Figure 8 is formed. The activation signal processing unit 130C in the third embodiment is formed from the control program that is to be executed by the sub-CPU used in the modification example of the first embodiment.

[0344] However, the activation signal processing unit 130 C, which is implemented by the sub-CPU, can be used in the second embodiment, and the activation signal processing unit 130B, which is implemented by the device logic, can be used in the third embodiment.

[0345] Furthermore, the second embodiment is described in the case of normal charging, and the third embodiment is described in the case of fast charging. Both normal and fast charging can be used in a vehicle, and any device logic type and / or sub-CPU type is used in practice.

[0346] Furthermore, when the power switch is closed, the arithmetic control units 120A, 102B, and 120C primarily perform the operational control for the main electrical device 104. However, the arithmetic control units 120A, 102B, and 120C can freely control the auxiliary electrical device 105 and are only restricted to the program memory to avoid performing unnecessary control operations. (3) Main point and features of the third embodiment

[0347] As is evident from the above description, the on-board vehicle electrical control device 100C, which includes the activation signal processing unit 130C, according to the third embodiment of the present invention, comprises: the arithmetic control unit 120C, which is configured to execute the control program that serves as the main control operating means 500, to start the control operation by applying the stabilized voltage Vcc from the on-board vehicle battery 101 through the power supply relay 103C, which is configured to respond to the closing operation of the power supply switch 102, and the stabilized power supply 110, so that the normal operating signal RUN is generated, maintain the closing operation of the power supply relay 103C and monitor an operating control for the main electrical device 104 and the response state to the operating control, wherein the arithmetic control unit is configuredto transfer and store at least part of the last current information (current information) to the non-volatile memory when the power supply switch 102 is opened, then suspend the normal operating signal RUN and discharge and suspend the power supply relay 103C; and the activation signal processing unit 130C, which is configured to execute the control program that serves as the auxiliary control device 530, to activate the arithmetic control unit 120C in response to the closing operations of the plurality of activation command elements 21a, 22a, ..., 2na, even when the power supply switch 102 is open, and to monitor the operating control for the auxiliary electrical device 105 and the response state to the operating control.

[0351] The arithmetic control unit 120C is configured to: start the control operations when the stabilized voltage Vcc is applied by the power supply relay 103 to be operated, to be closed, in response to the compound activation signal STC, and to use the normal operating signal RUN to maintain the operating state of the power supply relay 103C; and to read the individual activation signals SIG3n to perform the operating control for the auxiliary electrical device 105, and to generate the activation signal disconnect commands CNT3n2 to stop the output of the activation interlock units 62 until the generation of the normal operating signal RUN is stopped, as a result of the operation confirmation that accompanies the operating control, or the determination of a predetermined period passing.

[0352] The single activation processing unit 13n further comprises the separation interlock unit 64 and the recovery determination unit 67.

[0353] The separation interlock unit 64 is configured to be operated, to be set by the activation signal separation command CNT3n2, and to stop the generation of the composite activation signal STn when the plurality of activation command elements 2na are in the normally closed state or the irregularly closed state.

[0354] The recovery determination unit 67 is configured to reset the separation interlock unit 64 when the plurality of activation command elements 2na are in the normally open state or in the return-to-open state, and to enable the generation of the composite activation signal STn when the plurality of activation command elements 2na is closed.

[0355] The activation signal processing unit 130C includes the auxiliary microprocessor es CPU, to which energy is supplied by the backup power supply 114, to which energy is always supplied by the on-board vehicle battery 101 to generate the backup voltage Va.

[0356] The input interface circuit 160, which is a filter circuit, is provided between the activation auxiliary signal group 106C, which includes the multitude of auxiliary activation instruction circuits 2n, and the auxiliary microprocessor CPU.

[0357] The auxiliary microprocessor CPU forms the plurality of individual activation processing units 13n, the individual activation processing units 13n contain the control program that forms the activation instruction control of a 62, the separation interlock unit 64 and the recovery determination unit 67, and each of the plurality of individual activation processing units 13n is configured to generate the compound activation signal STn in order to charge the power supply relay 103C by using the compound activation signal STC.

[0358] Each of the plurality of single activation processing units 13n is further trained to generate the single activation signal SIG3n, which is directed to the arithmetic control unit 120C, and to receive from the arithmetic control unit 120C the interlock delete command CNT3n1, the separation state release command CNT3n3 and the irregularity diagnostic command CNT3n4, comprising at least the activation signal separation command CNT3n2.

[0359] As described above, according to the fifth aspect of the present invention, the activation signal processing unit, which is placed between the activation auxiliary signal group and the arithmetic control unit, comprises the auxiliary microprocessor, which is always supplied with energy from the on-board vehicle battery.

[0360] The main microprocessor, which forms the arithmetic control unit, has a large program memory, but this results in a long activation processing time and high energy consumption. In contrast, the auxiliary microprocessor has a smaller program memory, which offers the advantages of a short activation processing time and low energy consumption. It also allows the control program to implement various logic circuits without relying on individual circuits.

[0361] Thus, the following feature is provided. While the auxiliary microprocessor itself can directly read a short command signal, the energy consumption does not increase, even when power is constantly supplied from the vehicle's onboard battery.

[0362] In the on-board vehicle electrical control device 100C, the main electrical device 104, which includes the motor control unit 122C for the motor for driving 200, to which energy is to be supplied in order to be operated, from the on-board vehicle main battery 300, and the operating energy conversion circuit 210, and the auxiliary electrical device 105, which includes the charging control unit 121C for the main battery 300 and the on-board vehicle battery 101 and the charging energy conversion circuit 310, are combined in such a way as to form the complex electronic control devices 107 for an electric vehicle.

[0363] The complex electronic control devices 107 include the fast charging connection element 170, into which an increased DC voltage from the fast charger 109A is to be applied, which is a ground device, through the first charging cable.

[0364] The first activation command signal S31, which is generated in the connection state of the fast charging connection element 170, is entered into the activation signal processing unit 130C as the activation command signals S3nn, and the second activation command signal S32, which reacts to the energy reception state of the power supply terminal of the fast charging connection element 170, is entered to thereby generate the composite activation signal STC.

[0365] Furthermore, when the first activation command AS31 detects the connection state of the fast charging connection element 170, and the second activation command command signal S32 detects the energy receiving state of the fast charging connection element 170, the arithmetic control unit 120C applies a charging control of the main battery 300 and the on-board vehicle battery 101 by the charging control unit 121C, even if the power supply switch 102 is in the open state.

[0366] The activation signal processing unit 130C is configured to stop the power supply to the arithmetic control unit 120C when the fast charging connection element 170 is not in the power receiving state, even if the connection state of the fast charging connection element 170 is detected, and to start the power supply to each of the arithmetic control units 120C when the fast charging connection element 170 is determined to be in the power receiving state.

[0367] As described above, according to the sixth aspect of the present invention, the on-board vehicle electrical control device comprises the complex electronic control devices configured to perform the operational control of the motor for driving the electric vehicle and the charging control of the main battery for motor operation and the on-board vehicle battery, which is installed as the auxiliary battery for control purposes. The functions are distributed such that when the power supply switch is closed, the operational control is performed, and when the power supply switch is opened, the charging control is performed.

[0368] Charging the on-board vehicle battery to control the main battery can be performed while the power supply switch is closed, as an exception.

[0369] Thus, the following feature is provided.

[0370] During the indefinite standby period, which occurs from the connection of the charging cable until the start of the supply of the error energy supply, during the indefinite standby period caused by a blackout or an empty energy supply stoppage that occurs during charging, and during the indefinite standby period from the disconnection of the charging cable until the closing of the cover, the energy supply to the arithmetic control unit is stopped in order to prevent the occurrence of wasteful energy consumption in the non-charging state.

[0371] This is the same as in the second embodiment.

[0372] The mating connector, which is provided on the side of the first charging cable to be connected to the fast charging connection element 170A, includes the communication line designed to communicate the serial signal between the fast charger 109A and the arithmetic control unit 120C.

[0373] The arithmetic control unit 120C is designed to be powered in order to be operated by the activation signal processing unit 130C, in response to the first activation command signal S31, which serves as the communication start command signal “f” transmitted by the fast charger 109A, in order to transmit the charging specification which concerns the main battery 300, by using the serial signal, and to generate a control output signal CNT40, which serves as the charging authorization signal “k”, based on the confirmation response from the fast charger 109A.

[0374] The fast charger 109A is designed to transmit the charging start signal “g” in response to the received charging authorization signal “k”, so that the second activation command signal S32 is generated, and the charging of the main battery 300 is started by the activation signal processing unit 130C, the arithmetic control unit 120C and the charging control unit 121C.

[0375] The progress status of the charging of the main battery 300 is transmitted to the fast charger 109A using the serial signal and the communication start command signal “f” and the charging permit signal “k” are stopped when the control output signal CNT40 is stopped as a result of the completion of the charging.

[0376] As described above, according to a tenth aspect of the present invention, the first charging cable connected to the fast charging connection element comprises the serial signal line configured to transmit the charging specification for the main battery to the fast charger, to start charging using the communication start command signal “f”, to start charging using the charging start command signal “g”, and to give the progress status thereof to the fast charger.

[0377] Thus, the following feature is provided.
