Description

BACKGROUND OF THE INVENTIONField of the invention

[0001] The present invention relates to a vehicle control system and a wiring harness. Description of related prior art

[0002] Generally, in a vehicle, electrical components such as various loads, switches, sensors, electronic control units (ECUs), and the like are arranged in various areas such as a door, a roof, a floor, and a seat. Furthermore, electrical components of the respective areas are connected to each other via a wiring harness, so that necessary electrical power is supplied to each of these electrical components from the vehicle side, a plurality of electrical components can communicate with each other, and necessary signals can be input and output.

[0003] When a control function such as a microcomputer is arranged for each area, it is possible to cope with the difference in the electrical components in each area due to, for example, the difference in vehicle type or change in specification only by changing the software of the microcomputer or the like. However, when the microcomputers in the respective areas are commonly connected to the same network on the vehicle, it is necessary to assign identification information such as a unique ID or the like to the microcomputer of each area and perform appropriate control for each ID.

[0004] Meanwhile, in a vehicle, various pieces of equipment can be added as optional equipment in addition to the basic equipment, with specification changes or according to a user's requirements. Therefore, it is necessary to supply electrical power to additional equipment, generate a signal to control the equipment, and enable communication.

[0005] For example, JP 2014-166019 A relates to a wiring harness and an electronic control device and discloses a technique for easily adding an electronic device. Additionally, a vehicle harness structure according to JP 2014-166019 A discloses a technique for achieving commonality of wiring harness part numbers and eliminating the need to attach a wiring harness.

[0006] According to the prior art, in a vehicle control system including a wire harness, when designing a power supply box that supplies electric power to a downstream side or a subordinate cable, it is necessary to preliminarily determine the number of circuits in each part, the function to be installed, the connection form, and the like, assuming various pieces of equipment that may be added.

[0007] Therefore, as in the Fig. In the configuration illustrated in JP 2014-166019 A, for example, a plurality of connectors are provided in a power supply box, and a plurality of ECUs are respectively connected to the connectors via electrical wires with different wire harnesses. Then, auxiliary devices such as various electronic devices are connected to the downstream side of each ECU.

[0008] In other words, the total number of connectors that need to be installed in a power supply box, the number of electrical wires in a wiring harness, and the like must be predetermined based on the additional equipment assumed at the time of design. Therefore, if the assumed equipment is too large, unused, unnecessary connectors and electrical wires will proliferate, thus increasing the system cost. In addition, if the assumed equipment is insufficient, the equipment that can be added is limited, making it difficult to respond to specification changes and user requirements.

[0009] Additionally, as in Fig. 1 in JP 2014-166019 A, for example, when a control function is installed in a junction box, it is necessary to install a standard control unit and an extended control unit, respectively. Here, the design of the extended control unit must be made, pre-considering various pieces of equipment that can be added. Alternatively, if there is a need for a specification change or the like, it is necessary to decide on the function and configuration of a new extended control unit as a design change.

[0010] In other words, it is difficult to optimize the configuration when designing a power supply box or sub-cable, and requires redesigning power supply boxes and cables of different configurations, as well as increasing the types of parts associated with a vehicle's specification change, the addition of connecting equipment, and the like. Therefore, there is a concern that the development man-hours associated with reserving the design of additional equipment will increase, or that the management costs or parts costs will increase with the increase in the number of parts types.

[0011] JP 2016-60432 A discloses an electrical connection system for vehicles that electrically connects a power supply unit on a vehicle and a plurality of electrical components mounted on the vehicle. In order to make a part constituting a wire harness or the like common to a plurality of vehicles and to reduce overall costs by reducing the number of parts that become giveaways, the electrical connection system includes a base wire harness part connected to a power source at its upstream side and including an electrical power supply wire and an electrical communication wire, and in which a specification is predetermined.Further, the connection system includes a plurality of types of terminal-side harness parts arranged between a downstream side of the base harness part and a plurality of types of electrical components, allowing a change in a condition according to the connection number and specifications of a plurality of electrical components that are objects to be connected, and an intelligent control part that changes a control content in response to a difference in the conditions of a plurality of terminal-side harness parts connected to the harness part. Since the base harness part is common in use, a change in the condition of the terminal-side harness parts is made to cope with a change or the like in the specifications. The change in condition is handled by the intelligent control part.

[0012] DE 10 2015 216 310 A1 discloses a vehicle power control system for supplying electrical power from a power source of a vehicle to respective ones of a plurality of loads or electronic control units. The vehicle power control system includes a power distribution unit, a special information storage unit, and a power control unit. The power distribution unit receives the electrical power and distributes the electrical power to a plurality of systems. The special information storage unit stores special information in which operating specifications of the plurality of loads or electronic control units are determined. The power control unit controls the distribution of electrical power to the respective ones of the plurality of loads or electronic control units by the power distribution unit based on the operating specifications determined in the special information.

[0013] JP 2016-15809 A discloses a vehicle wiring harness structure having a common wiring harness article number capable of eliminating an unused portion of an attached wiring harness.The vehicle wiring harness structure includes a junction box containing a standard control unit for controlling standard electrical equipment and an extension control unit for controlling extension electrical equipment, a standard connection part arranged on the junction box for connecting one end of a standard wiring harness connected to the standard electrical equipment, and an extension connection part arranged on the junction box for connecting an extension wiring harness including at least one of a power supply line and a communication line to which one end of an additional connection member whose other end is connected to the extension electrical equipment is branched in an additional manner.

Therefore, it is possible to reduce the development man-hours associated with reserving the design of additional equipment. Additionally, since there is no need to preliminarily incorporate parts that are less likely to be used in the power distribution box, the cost of parts can be reduced.

[0022] In Fig. In the example illustrated in FIG. 1, a main line 51 of the wiring harness extends in a right-left direction in the vicinity of the front side of a passenger compartment of the vehicle body 50. Further, the main line 51 branches from the vicinity of a left end and a right end and extends in a front-rear direction of the vehicle compartment, so that the main line 51 is arranged to form an "H" shape. The main line 51 is used for electric power transmission and communication. Further, a plurality of power distribution boxes 52-1, 52-2, 52-3, 52-4, and 52-5 are connected in a distributed state at main locations of the main line 51.

Each of the connection portions 53-1 to 53-4 is a connection cable that includes a connector.

[0027] Therefore, the electrical power required by the electrical components of the respective equipment modules MO1 to MO4 can be supplied via one of the power distribution boxes 52-1 to 52-5 and the connection areas 53-1 to 53-4. In the following description, when it is not necessary to distinguish between the power distribution boxes 52-1 to 52-5, this will be referred to as the power distribution box 52. [Vehicle control system configuration example]

[0028] A configuration example of a vehicle control system according to the embodiment is shown in Fig. 2 illustrated.

[0029] The Fig. The vehicle control system illustrated in Figure 2 includes a power distribution box 52, downstream load modules 20-1 and 20-2, and a connecting cable C1. Here, the power distribution box 52, the downstream load modules 20-1 and 20-2, and the connecting cable C1 may be arranged on the vehicle body 50 as the power distribution box 52-1, the equipment modules MO1 and MO2, and the connecting area 53-1 (or 53-2), for example, in Fig. 1. Of course, similar vehicle control systems may be configured for the other power distribution boxes 52-2 through 52-5.

[0030] The Fig. The power distribution box 52 illustrated in FIG. 2 includes an electronic power distribution unit 11, a communication unit 12, a host ECU (electronic control unit) 13, and a standard interface (I / F) 14. The electronic power distribution unit 11 has a function of distributing the power supplied from the downstream side via the main line 51 and supplying it to the load on the downstream side. The host ECU 13 has a function of controlling the downstream load modules 20-1 and 20-2 and the like via the connection cable C1. The communication unit 12 provides a function for the host ECU 13 to communicate with a device on the downstream side via the connection cable C1. Also, there is a case where a function for the host ECU 13 to communicate with another power distribution box 52 via the main line 51 is mounted on the communication unit 12.

[0031] As in Fig. As illustrated in Figure 6, the power distribution box 52 includes a main line connection portion 57 to which the main line 51 is connected and which functions as a connector, and a connector 58 to which a connector CN11 of the connecting cable C1 connected to each of the downstream load modules 20-1 and 20-2 is fitted. The connector 58 has a plurality of insertion passages 14a and 14b formed therein.

[0032] The standard interface 14 has an insertion port 14a in a standardized form, which can be provided with a CN11 connector. Furthermore, it is also possible to prepare a plurality of similar insertion ports 14a in the standard interface 14. In addition, the insertion port 14a has terminals for connecting a power supply line, a ground line, and two communication lines, respectively.

[0033] Each of the downstream load modules 20-1 and 20-2, which are in Fig. 2, incorporates a connector 21, a switch 22, a sensor 23, a load 24, and a relay 25. Although not illustrated, the driver circuit for processing the signal input from the switch 22 and the sensor 23 and controlling the energization of the load 24 and the relay 25 is actually connected to the interior and exterior of each of the downstream load modules 20-1 and 20-2.

[0034] A configuration diagram of the connection cable C1 shown in Fig. 2 is illustrated in Fig. 5A and Fig. 5B. The connecting cable C1 consists of a power supply line 31, a ground wire 32 and a communication line 33 (for example, a twisted pair cable). Fig. The cable illustrated in Figure 5A is used to connect the power distribution box 52 and the downstream load module 20 on a one-to-one basis. In addition, the connecting cable C1 branches into Fig. 5B into a plurality of paths at a branching portion along its length. Connector CN11 is connected to an end portion C1b on the upstream side, and connectors CN21 and CN22 are connected to end portions C1c and C1d on the downstream side, respectively.

[0035] The connector 21 of each of the downstream load modules 20-1 and 20-2 has an insertion passage in a shape that can fit the connector CN21 or CN22 of the connecting cable C1. As shown in Fig. 2, Fig. 5A and Fig. 5B, circuit boards of connector control units EC21 and EC22 are provided in the housings of the connector control units EC21 and EC22, respectively.

[0036] Each of the connector control units EC21 and EC22 maintains information of a unique connector ID pre-assigned to each of the connector control units EC21 and EC22, and has a function of communicating with the host ECU 13 of the power distribution box 52 and a function of inputting / outputting necessary signals to / from the connector 21. Each of the connector control units EC21 and EC22 consists of a microcomputer or a dedicated electronic circuit. The specific operation of each of the connector control units EC21 and EC22 is described below.

[0037] The information about the connector ID held by each of the connector control units EC21 and EC22 is predetermined in advance so as to reflect the difference in configuration, type, specification, and the like of the downstream load modules 20-1 and 20-2 connected to its downstream side.

[0038] In the example of Fig. 2, the connector control units EC21 and EC22 are arranged in the connectors CN21 and CN22 of the connecting cable C1, respectively. However, the connector control units EC21 and EC22 may be arranged in the connectors 21 of the corresponding downstream load modules 20-1 and 20-2.

[0039] Furthermore, the vehicle control system can be connected in such a way that it Fig. 3 illustrated configuration.

[0040] In the vehicle control system of Fig. 3, a plurality of insertion holes 14a and 14b are pre-prepared in the standard interface 14A of the power distribution box 52A. These insertion holes 14a and 14b have the same shape. The power distribution box 52A and the downstream load module 20A are connected via a connecting cable C2A, and the power distribution box 52A and the downstream load module 20A are connected via a connecting cable C2B.

[0041] In the connecting cable C2A, the connector CN11 is provided at one end and the connector CN21 is provided at the other end. The connector CN21 incorporates the circuit board of the connector control unit EC21. In the connecting cable C2B, the connector CN11 is provided at one end and the connector CN22 is provided at the other end. The connector CN22 incorporates the circuit board of the connector control unit EC22.

[0042] In the configuration of Fig. 3, since the two insertion passages 14a and 14b have the same shape, the connector CN11 of the connecting cable C2A can be inserted into one of the plurality of insertion passages 14a and 14b. Also, the connector CN11 of the connecting cable C2B can be inserted into one of the plurality of insertion passages 14a and 14b.

[0043] Similar to the configuration of Fig. 2 also holds in the configuration of Fig. 3, the connector control unit EC21 holds the information of the connector ID according to the configuration, type, specification, or the like of the downstream load module 20-1, and the connector control unit EC22 holds the connector ID according to the configuration, type, specification, and the like of the downstream load module 20-2.

[0044] The plurality of insertion passages 14a and 14b of the standard interface 14a may be assigned to different communication passages independently of each other, or communication lines of a plurality of insertion passages 14a and 14b may be connected in parallel to the same communication passage. [Operation example of vehicle control system]

[0045] An operation example of the vehicle control system according to the embodiment is shown in Fig. 4. That is, when the power distribution box 52 and the downstream load module 20-1 and the like are connected with the connection cable C1, as shown in Fig. 2, a control of the procedure as in Fig. 4, between the host ECU 13 in the power distribution box 52 and the connector control unit EC21 in the connector CN21. The operation of Fig. 4 is described below.

[0046] When power is supplied from the main line 51 to the host ECU 13, the host ECU 13 supplies electric power to the connector control unit EC21 via a power supply line of the connection cable C1 (S11).

[0047] The connector control unit EC21 starts its operation when electric power is supplied from the connecting cable C1 and acquires a connector ID held by itself, for example, from an internal memory (S12). Then, the connector control unit EC21 transmits its own connector ID to the host ECU 13 via a communication line of the connecting cable C1 (S13).

[0048] The host ECU 13 receives the connector ID sent from the connector control unit EC21 and saves the connector ID in a connector ID table 13a in association with a communication passage (S14) that has received the connector ID.

[0049] The connector ID table 13a is located in a non-volatile memory in the host ECU 13 and is used to hold a list of connector IDs of the respective connectors actually connected to the downstream side of the host ECU 13. For example, when the connectors CN21 and CN22 are connected to the power distribution box 52 through the connecting cable C1, as previously illustrated, the connector ID of the connector control unit EC21 in the connector CN21 and the connector ID of the connector control unit EC22 in the connector CN22 are written and held by the connector ID table 13a.

[0050] The host ECU 13 incorporates a control software holding unit 13b. The control software holding unit 13b is a storage area facing the non-volatile memory or the like in the host ECU 13 and holds the control software for each connector ID registered therein in advance.

[0051] The host ECU 13 acquires the connector ID from each connector on the downstream side, and then the host ECU 13 executes control according to the connector ID for each connected connector (S15). That is, the host ECU 13 refers to the connector ID table 13a in such a way as to determine the connector ID of each connected connector. Therefore, the control software corresponding to each of the determined connector IDs is acquired from the control software holding unit 13b and executed.

[0052] For example, if the connectors CN21 and CN22 are connected to the power distribution box 52 by the connecting cable C1, as shown in Fig. As illustrated in Figure 2, the host ECU 13 communicates with the connector control unit EC21 and controls the downstream load module 20-1 using control software corresponding to the connector ID of the connector control unit EC21. Further, the host ECU 13 communicates with the connector control unit EC22 and controls the downstream load module 20-2 using control software corresponding to the connector ID of the connector control unit EC22.

[0053] Here, in the host ECU 13, a transmission destination of a signal for control software can be specified by the corresponding connector ID and communication port. Furthermore, on the connector control unit EC21 side, by referring to the connector ID included as information, such as a destination in the signal transmitted from the host ECU 13, it is possible to distinguish a signal addressed to itself from a signal addressed to another connector control unit EC22.

[0054] Therefore, the connector control unit EC21 performs control of each load in the downstream load module 20-1 while communicating with the host ECU 13 (S16). That is, a signal generated by the switch 22 or the sensor 23 is input from a predetermined port, the signal is encoded in a format corresponding to its own connector ID, and then the signal is sent to the host ECU 13. Further, a signal received from the host ECU 13 is decoded into a format corresponding to its own connector ID and output to a predetermined port, thereby controlling the load 24 or the relay 25.

[0055] For example, in Fig. In the downstream load module 20-1 illustrated in FIG. 2, when the load 24 is driven in accordance with the operating state of the switch 22, the following operation is performed. The signal output from the switch 22 is sent to the host ECU 13 in the power distribution box 52 via the connector control unit EC21 in the connector CN21, the connecting cable C1, and the connector CN11. By executing control software corresponding to the connector ID of the connector control unit EC21, the host ECU 13 processes an input signal from the switch 22 and generates a control signal for driving the load 24 according to the input signal. The control signal is output from the power distribution box 52 and received by the connector control unit EC21 in the connector CN21 via the connecting cable C1. The connector control unit EC21 decodes the received control signal and outputs it to the downstream side. As a result, the energization of load 24 is controlled.Therefore, the operation of the downstream load module 20-1 can be controlled by the host ECU 13.

[0056] In the operating example of Fig. 4 only illustrates communication between the host ECU 13 and the connector control unit EC21. However, the communication between the host ECU 13 and the connector control unit EC22 is also the same as in Fig. 4. Furthermore, not only the Fig. 2 illustrated vehicle control system, but also the one in Fig. 3 illustrated vehicle control system the same operation as in Fig. 4 carry out.

[0057] In the operating example of Fig. 4, it is assumed that the host ECU 13 acquires the connector ID from each of the downstream connectors CN21 and CN22 when the host ECU 13 is powered on. However, the same processes may be executed periodically, for example. [Advantages of vehicle control system of the embodiment]

[0058] In one case of a Fig. 2, a plurality of downstream load modules 20-1 and 20-2 of different types can be easily connected by connecting the connector CN11 of the connection cable C1, which branches along its length, to the insertion passage 14a of the standard interface 14. Furthermore, even in the case of a configuration of Fig. 3, it is possible to connect a plurality of downstream load modules 20-1 and 20-2 of different types by connecting a plurality of connecting cables C2a and C2b to a standard 14A interface of the power distribution box 52.

[0059] In addition, when the number of downstream load modules 20-1 and the like connected to the power distribution box 52 is increased, it is possible to add the downstream load modules 20-1 and the like without changing the configuration of the power distribution box 52 by adding connectors and electric wires branched in the course of a cable similar to the connecting cable C1.

[0060] For example, even if unexpected changes are made to the configuration and specifications of the downstream load module 20-1 or the like, if the connection cable is replaced with the connection cable C1 including the connector control unit EC21, with which a new connector ID is given, and control software corresponding to the new connector ID is added to the control software holding unit 13b of the host ECU 13, it can be used as it is without changing other configurations.

[0061] Therefore, when the power distribution box 52 is initially designed, there is no need to anticipate the possibility of future changes or additions and perform a reservation design, thus making it possible to greatly reduce development man-hours. However, it is not necessary to pre-incorporate components with low usability into the power distribution box 52, thus making it possible to eliminate waste and reduce parts costs.

[0062] Furthermore, differences in the configuration, type, and the like of the downstream load modules 20-1, 20-2, and the like connected to the downstream side of the connection cable C1 and the like can be distinguished by the connector ID given in advance to each of the connector control units EC21 and EC22, and thus a common standardized interface (14, 14A) can be used as the output of the power distribution box 52. With such commonality, the types of parts and the number of part numbers are reduced, and thus the management costs and the manufacturing costs of parts are reduced.
