Description

Technical Field

[0001] This invention relates to a vehicle control device. Background Technology

[0002] In recent years, from the perspective of SDGs (Sustainable Development Goals), electric vehicles that use electricity supplied from rechargeable batteries to power their motors have received much attention worldwide.

[0003] In such electric vehicles, onboard equipment such as air conditioning units that regulate the air inside the vehicle are electric, and driving power is supplied to the onboard equipment from the same battery that supplies power to the motor for driving.

[0004] Therefore, when multiple high-power in-vehicle devices such as air conditioning units are used during driving, the driving distance of electric vehicles may be shortened.

[0005] Therefore, there are disclosures of pre-heating and cooling of the vehicle interior by using the residual output of the charger to activate the air conditioning unit during the battery charging process when the electric vehicle is stopped (for example, see Patent Document 1).

[0006] If the temperature inside the car is adjusted in advance by pre-conditioning the air conditioning before starting the journey, the power consumed by the air conditioning system will be reduced after the journey begins. This not only increases the driving range of the electric vehicle, but also allows the driver to ride in the car after the cabin space has been made comfortable.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2001-63347 Summary of the Invention

[0008] The amount of power a battery can supply varies depending on temperature conditions. Supplying the battery with more power than it is allowed may cause damage to components.

[0009] As a representative example of the uncertainties in power consumption mentioned above, vehicle-mounted equipment such as air conditioning units, which consume a lot of power, can be cited.

[0010] For example, if occupants repeatedly turn on or off in-vehicle devices such as the air conditioner while the battery is charging, the energy consumption may change significantly sooner than if the ECU were to handle the process.

[0011] Assuming the battery can be supplied with 10kW of power and the power consumption of onboard equipment such as air conditioning is 1.5kW, from the perspective of charging efficiency, the preferred method is to supply 11.5kW of power to the battery from an external power source using a charger.

[0012] However, if passengers turn on or off vehicle equipment such as the air conditioning unit during battery charging, the supply of power may exceed the battery's allowable amount (11.5kW), potentially causing component damage.

[0013] To address the above situation, the following methods can be used: reduce the amount of electricity supplied to the battery, that is, set the amount of electricity supplied to the battery to the amount that can be supplied to the battery. For example, even if the occupants repeatedly turn on or off vehicle equipment such as air conditioning, no more than the amount of electricity that can be supplied will be supplied to the battery.

[0014] However, this method results in longer charging times due to reduced battery charging efficiency.

[0015] Therefore, the present invention was made in view of the above-mentioned problems, and its object is to provide a vehicle control device that supplies the battery with the maximum available power even when the power consumption of the on-board equipment varies.

[0016] Method 1: One or more embodiments of the present invention provide a vehicle control device, the vehicle including a first battery, a second battery, a switching unit for switching between the first battery and the second battery as a supply target of external power, and a control unit, characterized in that the control unit includes: a power demand calculation unit, which calculates the power demand obtained by adding the power that can be supplied to the first battery to the power required for the operation of the vehicle-mounted device when receiving external power; an operating state determination unit, which determines the operating state of the vehicle-mounted device; and a switching control unit, which executes the switching control of the switching unit, wherein when the external power is supplied to the first battery based on the power demand, and the vehicle-mounted device is operating, and the first battery receives the external power supply, and the vehicle-mounted device changes from an operating state to a non-operating state, the control unit controls the switching unit to supply the second battery with the power demand equal to the power required for the operation of the vehicle-mounted device.

[0017] Method 2: One or more embodiments of the present invention provide a vehicle control device, the vehicle including a first battery, a second battery, a switching unit for switching the supply target of external power supply, and a control unit, characterized in that the control unit has one or more processors and one or more memories communicatively connected to the one or more processors, the one or more processors performing the following control: when receiving external power supply, calculating the required power by adding the power that can be supplied to the first battery to the power required for the operation of the vehicle equipment; when the external power is supplied to the first battery based on the required power and the vehicle equipment is operating, during the period when the first battery receives the external power supply, and the vehicle equipment changes from an operating state to a non-operating state, causing the external power to supply the second battery with the power required for the operation of the vehicle equipment.

[0018] According to one or more embodiments of the present invention, the battery can be supplied with the maximum available power even if the power consumption of the vehicle equipment varies. Attached Figure Description

[0042] The first battery 110 is a rechargeable secondary battery.

[0043] The first battery 110 is, for example, a lithium-ion battery or other rechargeable battery, which supplies power to the vehicle's main drive system.

[0044] The first BMS111 monitors and controls the state of the cells constituting the first battery 110 on a per-unit basis, thereby enabling safe and long-term use of the first battery 110.

[0045] Specifically, the first BMS111 has the function of measuring the voltage of each battery cell or the battery pack as a whole constituting the first battery 110, and preventing overcharging or over-discharging.

[0046] In addition, the first BMS111 has the following functions: it measures the discharge current from each battery cell constituting the first battery 110 or the charging current to charge the battery, confirms the battery's usage status or charging status, and performs appropriate control.

[0047] Furthermore, the first BMS111 has the following function: it continuously monitors the temperature of each battery cell constituting the first battery 110 through temperature sensors, etc., and uses the battery within an appropriate temperature range, thereby ensuring the safety of the first battery 110 and extending the life of the first battery 110.

[0048] The second battery 120 is a rechargeable secondary battery.

[0049] The second battery 120 is, for example, a lithium-ion battery or other rechargeable battery, which supplies power to onboard equipment 150 and other devices mounted on the vehicle.

[0050] The second BMS121 monitors and controls the state of the second battery 120 on a unit basis, thereby enabling safe and long-term use of the second battery 120.

[0051] Furthermore, regarding the second BMS121, since it has the same functions as the first BMS111, detailed descriptions are omitted.

[0052] In order to charge the first battery 110 or the second battery 120, the charger 140 converts the AC power input from the fast charger into DC power and supplies it to the first battery 110 or the second battery 120.

[0053] In this embodiment, the charger 140 is connected to the first battery 110 via the first switching unit 160 described later, and is also connected to the first DC / DC converter 210 described later.

[0054] The vehicle-mounted equipment 150 is a device that operates by means of electricity and is mounted on a vehicle.

[0055] In this embodiment, the vehicle-mounted device 150 is a power-consuming device, such as an air conditioning unit.

[0056] Furthermore, in this embodiment, the vehicle-mounted device 150 will be described using an air conditioning unit as an example, but the vehicle-mounted device 150 may also be a power-consuming device such as a heater.

[0057] The first switching unit 160 is a component that switches the first battery 110 and the charger 140 to a connected state or a disconnected state, and a high-voltage relay can be exemplified as such.

[0058] The operating state of the first switching unit 160 is controlled based on the control signal from the control unit 500, which will be described later.

[0059] In this embodiment, as the charging of the first battery 110 begins, the first switching unit 160 switches from a disconnected, non-contact state to a closed, contact state.

[0060] The second switching unit 180 is a component that switches the second battery 120 and the charger 140 to a connected state or a disconnected state, and can be exemplified by a high-voltage relay.

[0061] The operating state of the second switching unit 180 is controlled based on the control signal from the control unit 500, which will be described later.

[0062] In this embodiment, in response to the moment when the charger 140 changes from an operating state to a non-operating state, the second switching unit 180 switches from a disconnected non-contact state to a closed contact state.

[0063] The first DC / DC converter 210 is, for example, a non-isolated bidirectional DC-DC converter.

[0064] The first DC / DC converter 210 includes multiple switching elements.

[0065] The reference circuit of the first DC / DC converter 210 is connected to the negative side of the first battery 110 and the negative side of the INV230 (described later). The high-voltage circuit is connected to the positive side of the INV230, and the low-voltage circuit is connected to the positive side of the first battery 110.

[0066] The reference circuit of the second DC / DC converter 220 is connected to the negative side of the second battery 120 and the negative side of the INV230 described later. The high voltage circuit is connected to the positive side of the INV230, and the low voltage circuit is connected to the positive side of the second battery 120.

[0067] In addition, the vehicle-mounted device 150 is connected between the second DC / DC converter 220 and the second switching unit 180. The negative side of the vehicle-mounted device 150 is connected to the reference circuit, and the positive side of the vehicle-mounted device 150 is connected to the low-voltage circuit.

[0068] INV230 converts the DC power supplied from the first DC / DC converter 210 or the second DC / DC converter 220 into AC power, and supplies the AC power with varying frequency and voltage to the first electric generator 240 and the second electric generator 250, which are described later, based on control signals from the control unit 500.

[0069] In addition, in this embodiment, when the second switching unit 180 is in the connected state, the AC power supplied from the charger 140 is supplied to the second battery 120 via the first DC / DC converter 210 and the second DC / DC converter 220 and INV 230, and the second battery 120 is charged.

[0070] The first electric generator 240 integrates the starting function of a starter and the power generation function of an alternator.

[0071] The first electric generator 240 incorporates a wide range of technologies, including idle stop, engine assistance during driving, and energy regeneration during deceleration, which helps improve fuel efficiency.

[0072] In addition, the first electric generator 240 helps to improve vehicle compatibility based on mechatronics, quiet start-up based on drive, rapid restart based on control technology and high engine rotation assist, high-efficiency power generation based on winding technology, and low noise.

[0073] Furthermore, the second electric generator 250 has the same functions and advantages as the first electric generator 240, so detailed descriptions are omitted.

[0074] The transmission mechanism 260 includes a reducer, a gearbox, etc.

[0075] Differential gears 261 and 262 are gears that absorb the speed difference between the inner and outer wheels of the vehicle.

[0076] The output shafts of the first electric generator 240 or the second electric generator 250 are connected to the transmission mechanism 260.

[0077] Additionally, the output shaft of the transmission mechanism 260 is connected to differential gears 261 and 262. Power from the second electric generator 250 is transmitted to the axle via differential gear 261, driving the front wheels 291. Power from the first electric generator 240 is transmitted to the axle via differential gear 262, driving the rear wheels 292.

[0078] The control unit 500 executes the overall processing of the vehicle control device 1 of this embodiment based on the control program stored in a storage unit (not shown) such as ROM (Read Only Memory) or RAM (Random Access Memory).

[0079] For example, when a predetermined condition is met, the control unit 500 activates the first switching unit 160 to switch the first battery 110 and the charger 140 to a connected state or a disconnected state.

[0080] In addition, when a predetermined condition is met, the control unit 500 activates the second switching unit 180 to switch the second battery 120 and the charger 140 to a connected state or a disconnected state.

[0081] <Structure of Control Unit 500>

[0082] like Figure 2 As shown, the control unit 500 of this embodiment includes a processor 510 and a memory 520.

[0083] In this embodiment, when the processor 510 receives external power from the charger 140, it calculates the required power by adding the power that can be supplied to the first battery 110 and the power required for the vehicle device 150 to operate. When the vehicle device 150 changes from an operating state to a non-operating state while the first battery 110 receives external power from the charger 140 based on the required power, the processor 510 supplies the second battery 120 with power equal to the power required for the vehicle device 150 to operate.

[0084] The memory 520 is composed of ROM or RAM, etc., and stores programs and various data.

[0085] The memory 520 is provided with a storage unit 521, which stores information such as the conditions under which the processor 510 supplies the second battery 120 with the same amount of power required for the vehicle equipment 150 to operate.

[0086] <Structure of Processor 510>

[0087] like Figure 2 As shown, the processor 510 of the vehicle control device 1 in this embodiment includes a power demand calculation unit 511, an operating status determination unit 512, and a switching control unit 513.

[0088] In addition, such as Figure 2 As shown, the switching control unit 513, the power demand calculation unit 511, the working status determination unit 512, the memory 520, etc. are connected via the bus BL.

[0089] When receiving external power through charger 140, power demand calculation unit 511 calculates the power demand by adding the power that can be supplied to the first battery 110 and the power required for the operation of vehicle equipment 150.

[0090] The calculation result calculated in the power demand calculation unit 511 is output to the switching control unit 513 via the bus BL.

[0091] The working status determination unit 512 determines the working status of the vehicle-mounted equipment 150.

[0092] The determination result determined in the working status determination unit 512 is output to the switching control unit 513 via the bus BL.

[0093] The switching control unit 513 performs switching control on the first switching unit 160 or the second switching unit 180.

[0094] In particular, the switching control unit 513 in this embodiment is only a switching control unit that performs on / off operation without charging or discharging between the first battery 110 and the second battery 120, and performs control to charge the first battery 110 or the second battery 120 respectively.

[0095] Specifically, for example, as the first battery 110 begins to charge, the temperature of the first battery 110 rises, and the amount of electricity that can be supplied to the system increases over time.

[0096] In addition, Figure 4 In this context, the air conditioning unit 150, being an on-board device, is in the on-board state. Therefore, the amount of electricity that can be supplied to the system is the sum of the electricity required by the system and the electricity required by the air conditioning unit 150 to maintain its operating state (refer to...). Figure 4 (1) in the middle.

[0097] Therefore, the system is supplied with an amount of electricity equal to the power required described above by means of an external power source via charger 140.

[0098] Next, when the air conditioning unit 150, which is a vehicle-mounted device, changes from being turned on to being turned off, there is no longer the power required by the air conditioning unit 150 to maintain its working state. Therefore, the power demand mentioned above is reduced, resulting in the power supplied from the external power source exceeding the power required by the system.

[0099] Therefore, by turning on the second switching unit 180, the remaining power is supplied to the second battery 120, thereby suppressing the supply of excess power to the first battery 110 (see reference). Figure 4 (2) Figure 5 ).

[0100] Then, at the stage where the amount of electricity supplied to the first battery 110 is equal to the amount of electricity required by the system, control is performed to change the second switching unit 180 from on to off (see reference). Figure 4 (3) Figure 5 ).

[0101] In other words, when external power is supplied to the first battery 110 via charger 140 based on the power demand calculated in power demand calculation unit 511 and the vehicle equipment 150 is operating (see reference). Figure 4In (1), during the period when the first battery 110 receives external power supply via the charger 140, the on-board equipment 150 is determined to change from an operating state to a non-operating state based on the determination result of the operating state determination unit 512 (see reference). Figure 4 When (2) etc., the switching control unit 513 performs switching control to set the second switching unit 180 to the off state, so that the second battery 120 is supplied with an amount of electricity equal to the amount of electricity required for the operation of the vehicle equipment 150.

[0102] Furthermore, although the second switching unit 180 turns off when the vehicle-mounted device 150 changes from an operating state to a non-operating state, it still supplies the first battery 110 with the amount of electricity that can be supplied to the first battery 110, so it does not discharge from the first battery 110 to the second battery 120.

[0103] <Processing of vehicle control unit 1>

[0104] use Figure 3 This explains the processing of the vehicle control device 1 in this embodiment.

[0105] The control unit 500 determines whether the charging operation using the charger 140 has started (step S110).

[0106] When the control unit 500 determines that charging operation with the help of the charger 140 has not started (No in step S110), the processing is transferred to standby mode.

[0107] On the other hand, when the control unit 500 determines that charging operation with the help of the charger 140 has started ("Yes" in step S110), the process is transferred to step S120.

[0108] At this time, the control unit 500 sends a control signal to the switching control unit 513 to change the first switching unit 160 from a non-connected state to a connected state.

[0109] If the switching control unit 513 receives a control signal to change the first switching unit 160 from a non-connected state to a connected state, it executes the control to change the first switching unit 160 from a non-connected state to a connected state (step S120).

[0110] Next, the control unit 500 determines whether the vehicle-mounted device 150 has changed to an operating state based on the determination result of the operating state determination unit 512 (step S130).

[0111] When the control unit 500 determines, based on the determination result of the working state determination unit 512, that the vehicle-mounted device 150 has not changed to the working state (No in step S130), the processing is transferred to the standby mode.

[0112] On the other hand, when the control unit 500 determines that the vehicle device 150 has become a working state based on the determination result of the working state determination unit 512 ("Yes" in step S130), it determines whether the vehicle device 150 has become a non-working state (step S140).

[0113] When the control unit 500 determines that the vehicle-mounted device 150 has not changed to a non-working state (No in step S140), it returns the processing to step S130 and switches to standby mode.

[0114] On the other hand, when the control unit 500 determines that the vehicle-mounted device 150 has become non-working ("Yes" in step S140), it sends a control signal to the switching control unit 513 to change the second switching unit 180 from a non-connected state to a connected state.

[0115] If the switching control unit 513 receives a control signal to change the second switching unit 180 from a non-connected state to a connected state, it executes the control to change the second switching unit 180 from a non-connected state to a connected state (step S150).

[0116] Next, the control unit 500 determines the amount of electricity (W) supplied to the first battery 110. B1 Is it related to the system's required power (W)? S Equal (step S160).

[0117] Additionally, when the control unit 500 determines the amount of electricity (W) supplied to the first battery 110... B1 ) and the power required by the system (W) S If the values ​​are not equal (No in step S160), the process will be transferred to standby mode.

[0118] On the other hand, when the control unit 500 determines that the amount of electricity (W) supplied to the first battery 110 is... B1 ) and the power required by the system (W) S When the two states are equal ("Yes" in step S160), a control signal is sent to the switching control unit 513 to change the second switching unit 180 from the connected state to the disconnected state.

[0119] If the switching control unit 513 receives a control signal to change the second switching unit 180 from the connected state to the disconnected state, it executes the control to change the second switching unit 180 from the connected state to the disconnected state (step S170).

[0120] In addition, the control unit 500 terminates the processing.

[0121] <Functions and Effects>

[0122] As explained above, the vehicle control device 1 of this embodiment includes a first battery 110, a second battery 120, a first switching unit 160 and a second switching unit 180 for switching the supply target from external power supply, and a control unit 500. The control unit 500 includes: a power demand calculation unit 511, which calculates the power demand obtained by adding the power that can be supplied to the first battery 110 and the power required for the vehicle equipment 150 to operate when receiving external power supply; an operating state determination unit 512, which determines the operating state of the vehicle equipment 150; and a switching control unit 513, which executes the switching control of the first switching unit 160 or the second switching unit 180. When the vehicle equipment 150 changes from an operating state to a non-operating state during the period when external power is supplied to the first battery 110 based on the power demand and the vehicle equipment 150 is operating and the first battery is receiving external power supply, the control unit 500 controls the first switching unit 160 or the second switching unit 180 so that the power supply from external power to the second battery is equal to the power required for the vehicle equipment 150 to operate.

[0123] In other words, when the control unit 500 receives an external power supply, it supplies external power to the first battery 110 based on the required power.

[0124] In addition, when the vehicle-mounted device 150 changes from an operating state to a non-operating state while the first battery is receiving external power, the control unit 500 controls the first switching unit 160 or the second switching unit 180 to supply the second battery with an amount of power equal to the power required for the operation of the vehicle-mounted device 150 from the external power source.

[0125] Therefore, it is possible to prevent the following situation: when, as in the past, the amount of electricity supplied to the first battery 110 plus the amount of electricity supplied to the vehicle equipment 150 is supplied from the point of view of charging efficiency, and the vehicle equipment 150 changes from an operating state to a non-operating state, resulting in the supply of more electricity than the first battery 110 is allowed.

[0126] Additionally, when the vehicle-mounted equipment 150 is in an operational state, the control unit 500, such as Figure 5 As shown, the second battery 120 can be supplied with the amount of electricity obtained by subtracting the amount of electricity supplied to the first battery 110 from the amount of electricity supplied from the external power supply.

[0127] Therefore, even if the power consumption of the on-board equipment 150 changes, it can still supply the battery with the maximum amount of power that can be supplied to the first battery 110 and the second battery 120.

[0128] In this embodiment, the vehicle-mounted equipment 150 is an air conditioning unit.

[0129] The air conditioning unit in vehicle 150 is a frequently used device throughout the year and consumes a lot of electricity.

[0130] In other words, air conditioning equipment is used frequently and consumes a lot of electricity, so it requires more electricity than other vehicle equipment. The difference in electricity consumption between when the air conditioning equipment is turned on and when it is turned off is also large.

[0131] Therefore, the vehicle control device 1 of this embodiment is particularly effective when the vehicle-mounted equipment 150 is an air conditioning device.

[0132] Furthermore, by recording the processing of the processor 510 on a computer-readable recording medium, the processor 510 reads and executes the program recorded on the recording medium, thereby enabling the vehicle control device 1 of the present invention to be implemented. The computer system referred to herein includes hardware such as an OS (operating system) and peripheral devices.
