Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle power supply, in particular to a power supply system for vehicle driving and a vehicle. BACKGROUND

[0002] In the field of automatic driving, the power supply mode of setting redundant power supply is usually used to meet the demand that one of the power supplies can continue to support the normal work of the system when the other one fails.

[0003] At present, the power supply mode of setting redundant power supply usually sets a main power supply circuit and a secondary power supply circuit for two-way power input, and the main power supply circuit and the secondary power supply circuit are electrically connected through a bridging diode. When the voltage of any one of the main power supply circuit and the secondary power supply circuit decreases, the bridging switch element will be turned on. In this way, when a fault short circuit or disconnection occurs in any one of the main power supply circuit and the secondary power supply circuit, the mutual redundancy between the main power supply circuit and the secondary power supply circuit can be realized through the intermediate switch element.

[0004] However, if the voltage of the main power supply circuit and the voltage of the secondary power supply circuit are disturbed, causing the voltage difference between the main power supply circuit and the secondary power supply circuit to exceed 50mV, the bridging diode between the main power supply circuit and the secondary power supply circuit will be turned on, thereby causing the power supply switching between the main power supply circuit and the secondary power supply circuit. If the power provided by any one of the main power supply circuit and the secondary power supply circuit is less than the total power required by the main power supply circuit and the secondary power supply circuit, the direct current converter electrically connected to the main power supply circuit and the secondary power supply circuit will be overloaded, and the voltage of the battery electrically connected to the main power supply circuit and the secondary power supply circuit will be lowered. Based on this, in the above-mentioned power supply mode of redundant power supply, the power supply power of the main power supply circuit and the secondary power supply circuit usually needs to be set large to ensure the normal power supply, thereby causing energy consumption and cost waste.

[0038] Please refer to Figure 1 The power supply system for vehicle driving provided by the embodiments of the present application comprises:

[0039] The power supply assembly 1, the first DC converter 2 and the second DC converter 3 are electrically connected with the power supply assembly 1 respectively.

[0040] The power distribution assembly 4, the first storage battery 5 and the second storage battery 6, the power distribution assembly 4 comprises a main power distribution circuit 41 and a secondary power distribution circuit 42, the main power distribution circuit 41 is electrically connected with the first DC converter 2 and the first storage battery 5, and the secondary power distribution circuit 42 is electrically connected with the second DC converter 3 and the second storage battery 6.

[0041] The control module 01 includes at least one control component, the control component for actively controlling the vehicle in the control module 01 is electrically connected to the main power distribution circuit 41, the control component for automatically controlling the vehicle in the control module 01 is electrically connected to the auxiliary power distribution circuit 42, and the control component for controlling the safety of the vehicle in the control module 01 is electrically connected to both the main power distribution circuit 41 and the auxiliary power distribution circuit 42.

[0042] As can be seen from the above embodiment, in the embodiment of the present application, since the power distribution assembly 4 includes the main power distribution circuit 41 and the auxiliary power distribution circuit 42, the main power distribution circuit 41 is electrically connected to the first direct-current converter 2 and the first storage battery 5, and the auxiliary power distribution circuit 42 is electrically connected to the second direct-current converter 3 and the second storage battery 6, the power supply system can be powered by both the power supply assembly 1 and the first storage battery 5 and the second storage battery 6, thereby meeting the hardware design requirement of dual-power input of the power supply system. In addition, since the control module 01 includes at least one control component, the control component for actively controlling the vehicle in the control module 01 is electrically connected to the main power distribution circuit 41, the control component for automatically controlling the vehicle in the control module 01 is electrically connected to the auxiliary power distribution circuit 42, and the control component for controlling the safety of the vehicle in the control module 01 is electrically connected to both the main power distribution circuit 41 and the auxiliary power distribution circuit 42, only the control component for controlling the safety of the vehicle is designed to be power-redundant, and the other control components included in the control module 01 are not designed to be power-redundant.

[0043] In summary, the power supply system provided by the embodiment of the present application can ensure that the control component for controlling the safety of the vehicle can continue to be powered by the other power distribution circuit when any one of the main power distribution circuit 41 and the auxiliary power distribution circuit 42 fails, thereby ensuring the safety performance of the power supply system for vehicle driving, and can reduce the maximum power provided by the main power distribution circuit 41 and the auxiliary power distribution circuit 42 by designing only the control component for controlling the safety of the vehicle to be power-redundant and not designing the other control components included in the control module 01 to be power-redundant, that is, without increasing the power of the main power distribution circuit 41 and the auxiliary power distribution circuit 42, the normal power supply of the power supply system for vehicle driving can be ensured, thereby saving energy consumption and cost.

[0044] In the above embodiment, the power supply assembly 1 can be a high-voltage battery, a high-voltage power box, or other devices with high-voltage power input. The first DC converter 2 and the second DC converter 3 convert the high-voltage DC power of the power supply assembly 1 into low-voltage DC power. After voltage conversion by the first DC converter 2 and the second DC converter 3, a stable voltage can be output to ensure normal operation of the power supply system. At the same time, since the main power distribution circuit 41 is electrically connected to the first DC converter 2 and the first battery 5, and the auxiliary power distribution circuit 42 is electrically connected to the second DC converter 3 and the second battery 6, the first battery 5 can be charged by the first DC converter 2, and the first battery 5 can be charged by the second DC converter. At the same time, the power supply system can be powered by the power supply assembly 1, the first battery 5 and the second battery 6, and the hardware design requirement of dual power input of the power supply system can be realized. It should be noted that the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3 are equal. For example, the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3 can both be 1.5KW.

[0045] It should be noted that the control module 01 in the embodiment of the application can include a plurality of different types of control assemblies, and the type of control assembly is determined according to the requirements of the vehicle and the functions required to be achieved. The embodiment of the application does not limit this. In the case where the control module 01 in the embodiment of the application includes one control assembly, the control module at least includes a control assembly for controlling the safety of the vehicle that is electrically connected to the main power distribution circuit 41 and the auxiliary power distribution circuit 42 at the same time to achieve the technical problem solved by the application.

[0046] In some embodiments, the control module 01 includes at least one of a safety control assembly 7, a proactive driving control assembly 8, and an automatic driving control assembly 9. The safety control assembly 7 is electrically connected to the main power distribution circuit 41 and the auxiliary power distribution circuit 42 at the same time. The proactive driving control assembly 8 is electrically connected to the main power distribution circuit 41. The automatic driving control assembly 9 is electrically connected to the auxiliary power distribution circuit 42. The proactive driving control assembly 8 is used to actively control the vehicle. The automatic driving control assembly 9 is used to automatically control the vehicle. The safety control assembly 7 is used to control the safety of the vehicle.

[0047] In this embodiment, the maximum power provided by the main power distribution circuit 41 and the auxiliary power distribution circuit 42 can be reduced by only providing power redundancy design for the safety control component 7, and not providing power redundancy design for the active driving control component 8 and the automatic driving control component 9. It should be noted that the safety control component 7 is the main control element for controlling the safety of the vehicle, and therefore the safety control component 7 needs to be provided with power redundancy design to ensure that the safety control component 7 can continue to be powered by another power distribution circuit when any power distribution circuit fails, so as to ensure the safety performance of the power supply system for driving the vehicle.

[0048] In some embodiments, the power supply system further includes a first switching element 101, a second switching element 102, a third switching element 103, and a fourth switching element 104. The power distribution component 4 includes a first power input end and a second power input end, the first power input end is electrically connected with the main power distribution circuit 41, and the second power input end is electrically connected with the auxiliary power distribution circuit 42. The first power input end is electrically connected with the first DC converter 2 through the first switching element 101, the second power input end is electrically connected with the first DC converter 2 through the second switching element 102, the first storage battery 5 is electrically connected with the main power distribution circuit 41 through the third switching element 103, and the second storage battery 6 is electrically connected with the auxiliary power distribution circuit 42 through the fourth switching element 104.

[0049] In this embodiment, since the first power input end is electrically connected with the first DC converter 2 through the first switching element 101, the second power input end is electrically connected with the first DC converter 2 through the second switching element 102, the first storage battery 5 is electrically connected with the main power distribution circuit 41 through the third switching element 103, and the second storage battery 6 is electrically connected with the auxiliary power distribution circuit 42 through the fourth switching element 104, the switching of the power supply of the main power distribution circuit 41 and the auxiliary power distribution circuit 42 between the first DC converter 2, the second DC converter 3, the first storage battery 5, and the second storage battery 6 can be realized by controlling the on-off of the first switching element 101, the on-off of the second switching element 102, the on-off of the third switching element 103, and the on-off of the fourth switching element 104, so as to realize that when any power supply in the first DC converter 2, the second DC converter 3, the first storage battery 5, and the second storage battery 6 fails, the power supply system can be switched to other power supply for power supply.

[0050] It should be noted that the first switching element 101, the second switching element 102, the third switching element 103, and the fourth switching element 104 can be any one of ideal diodes, MOS tubes, and other control electronic elements, and the embodiments of the present application do not limit this.

[0051] In some embodiments, the power supply system further comprises a control chip, and the first switch element 101, the second switch element 102, the third switch element 103 and the fourth switch element 104 are all electrically connected with the control chip.

[0052] In this way, the switching of the power supply between the first DC converter 2, the second DC converter 3, the first storage battery 5 and the second storage battery 6 can be realized by controlling the on-off of the first switch element 101, the on-off of the second switch element 102, the on-off of the third switch element 103 and the on-off of the fourth switch element 104 through the control chip, so as to realize the accuracy of the power supply switching.

[0053] In the case of failure of the first DC converter 2, the control chip controls the first switch element 101 to be in an off state, and the second switch element 102, the third switch element 103 and the fourth switch element 104 are all in an on state.

[0054] In this embodiment, since the control chip controls the first switch element 101 to be in an off state, and the second switch element 102, the third switch element 103 and the fourth switch element 104 are all in an on state, the main power distribution circuit 41 can be powered by the first storage battery 5, so that the main power distribution circuit 41 can work normally for a period of time, and the vehicle can be parked on the roadside for a certain period of time.

[0055] In the case of failure of the second DC converter 3, the control chip controls the second switch element 102 to be in an off state, and the first switch element 101, the third switch element 103 and the fourth switch element 104 are all in an on state.

[0056] In this embodiment, since the control chip controls the second switch element 102 to be in an off state, and the first switch element 101, the third switch element 103 and the fourth switch element 104 are all in an on state, the secondary power distribution circuit 42 can be powered by the second storage battery 6, and since the automatic driving control component 9 and the safety control component 7 connected in the secondary power distribution circuit 42 can lower the voltage of the secondary power distribution circuit 42, the main control unit, the vehicle control unit 72 and the gateway control unit 73 included in the safety control component 7 can be switched to the main power grid for power supply, and the automatic driving control component 9 can be powered by the secondary power distribution circuit 42, so that the vehicle can be parked on the roadside for a certain period of time.

[0057] In the case of failure of the first storage battery 5, the control chip controls the third switch element 103 to be in an off state, and the first switch element 101, the second switch element 102 and the fourth switch element 104 are all in an on state.

[0058] In this embodiment, since the control chip controls the third switching element 103 to be in the off state, the first switching element 101, the second switching element 102 and the fourth switching element 104 are all in the on state, so the battery can be prevented from affecting the normal power supply of the main power distribution circuit 41, the first direct current converter 2 can start to supply power to the main power distribution circuit 41, and the main power distribution circuit 41 can work normally for a period of time, ensuring that the vehicle can be handled in an emergency within a certain period of time.

[0059] In the case of failure of the second battery 6, the control chip controls the fourth switching element 104 to be in the off state, and the first switching element 101, the second switching element 102 and the third switching element 103 are all in the on state.

[0060] In this embodiment, since the control chip controls the fourth switching element 104 to be in the off state, the first switching element 101, the second switching element 102 and the third switching element 103 are all in the on state, so the second direct current converter 3 can start to supply power to the auxiliary power distribution circuit 42, and the auxiliary power distribution circuit 42 can work normally for a period of time, ensuring that the vehicle can be handled in an emergency within a certain period of time.

[0061] In some embodiments, the power supply system further comprises a power supply control component, the first direct current converter 2 and the second direct current converter 3 are electrically connected to the power supply control component, the power supply control component controls the input voltage of the first direct current converter 2 to the main power distribution circuit 41 to be a first voltage, and the power supply control component controls the input voltage of the second direct current converter 3 to the auxiliary power distribution circuit 42 to be a second voltage, wherein the second voltage is greater than the first voltage.

[0062] In this embodiment, the power supply control component can control the input voltage of the first direct current converter 2 to the main power distribution circuit 41 to be less than the input voltage of the second direct current converter 3 to the auxiliary power distribution circuit 42, so that the voltage difference between the main power distribution circuit 41 and the auxiliary power distribution circuit 42 can be set, and the safety control component 7 can be supplied by the auxiliary power distribution circuit 42 in the normal working state, thereby improving the power of the safety control component 7 in the auxiliary power distribution circuit 42. In other words, since the power of the active driving control component 8 is greater than the power of the automatic driving control component 9, the safety control component 7 with a larger power ratio is supplied by the auxiliary power distribution circuit 42, avoiding the safety control component 7 being supplied by the main power distribution circuit 41 and causing the first direct current converter 2 to be overloaded, affecting the normal operation of the vehicle.

[0063] In some embodiments, the difference between the second voltage and the first voltage is greater than or equal to 0.5V when the first switch element 101, the second switch element 102, the third switch element 103 and the fourth switch element 104 are all in the on state.

[0064] In this embodiment, the difference between the second voltage and the first voltage can be set to ensure that the safety control component 7 is powered through the secondary power distribution circuit 42 when the power supply system is in a normal state.

[0065] In some embodiments, the safety control component 7 includes an intelligent driving master control unit 71, a vehicle control unit 72 and a gateway control unit 73. The intelligent driving master control unit 71, the vehicle control unit 72 and the gateway control unit 73 are each equipped with an internal power supply 105, and a fifth switch element 106 is electrically connected between the intelligent driving master control unit 71 and the primary power distribution circuit 41, between the intelligent driving master control unit 71 and the secondary power distribution circuit 42, between the vehicle control unit 72 and the primary power distribution circuit 41, between the vehicle control unit 72 and the secondary power distribution circuit 42, and between the gateway control unit 73 and the primary power distribution circuit 41, and between the gateway control unit 73 and the secondary power distribution circuit 42.

[0066] In this embodiment, since the intelligent driving master control unit 71, the vehicle control unit 72 and the gateway control unit 73 are each equipped with an internal power supply 105, the voltage conversion of the internal chips of the intelligent driving master control unit 71 can be achieved by the internal power supply 105 of the intelligent driving master control unit 71, the voltage conversion of the internal chips of the vehicle control unit 72 can be achieved by the internal power supply 105 of the vehicle control unit 72, and the voltage conversion of the internal chips of the gateway control unit 73 can be achieved by the internal power supply 105 of the gateway control unit 73. Since the fifth switch element 106 is electrically connected between the intelligent driving master control unit 71 and the primary power distribution circuit 41, between the intelligent driving master control unit 71 and the secondary power distribution circuit 42, between the vehicle control unit 72 and the primary power distribution circuit 41, between the vehicle control unit 72 and the secondary power distribution circuit 42, between the gateway control unit 73 and the primary power distribution circuit 41, and between the gateway control unit 73 and the secondary power distribution circuit 42, the current path control and internal voltage stabilization of the intelligent driving master control unit 71 can be achieved by the fifth switch element 106, the current path control and internal voltage stabilization of the vehicle control unit 72 can be achieved by the sixth switch element 107, and the current path control and internal voltage stabilization of the gateway control unit 73 can be achieved by the seventh switch element 108, thereby ensuring the normal operation of the intelligent driving master control unit 71, the vehicle control unit 72 and the gateway control unit 73.

[0067] It should be noted that the intelligent driving master control unit 71 is the core computing and control center of the intelligent driving system, which undertakes tasks such as sensor data processing, decision planning, and execution control. The vehicle control unit 72 is a control center for controlling the running state of the vehicle, which can include the vehicle control unit 72, chassis domain control unit, body domain control unit, etc. The gateway control unit 73 is the core communication hub in the vehicle electronic architecture, mainly responsible for coordinating data transmission and protocol conversion between different electronic control units, and ensuring efficient cooperation of various systems of the vehicle.

[0068] In some embodiments, the active driving control component 8 includes a body control unit 81, a cabin control unit 82, a main steering control unit 83, a main brake control unit 84, and a redundant intelligent driving control unit 85. The autonomous driving control component 9 includes a redundant brake control unit 91, a redundant steering control unit 92, a laser ranging unit 93, and a positioning unit 94.

[0069] In this embodiment, since the active driving control component includes the body control unit 81, the cabin control unit 82, the main steering control unit 83, the main brake control unit 84, and the redundant intelligent driving control unit 85. The autonomous driving control component 9 includes a redundant brake control unit 91, a redundant steering control unit 92, a laser ranging unit 93, and a positioning unit 94, therefore when the body control unit 81, the cabin control unit 82, the main steering control unit 83, and the intelligent driving master control unit 71 fail, the redundant intelligent driving control unit 85, the redundant brake control unit 91, and the redundant steering control unit 92 can access the operation of the vehicle to ensure the safety of the vehicle operation, and the laser ranging unit 93 and the positioning unit 94 can realize the accuracy of autonomous driving of the vehicle, further ensuring the safety of vehicle movement.

[0070] In some embodiments, the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3 are equal to the first power, the total power of the safety control component 7 and the active driving control component 8 is the second power, the total power of the safety control component 7 and the autonomous driving control component 9 is the third power, the first power is greater than the second power, and the difference between the first power and the second power tends to 0 value, the first power is greater than the third power, and the difference between the first power and the third power tends to 0 value.

[0071] In the embodiment, since the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3 are both greater than the total power of the safety control component 7 and the active driving control component 8, and the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3 are both greater than the total power of the safety control component 7 and the automatic driving control component 9, it can be guaranteed that the first DC converter 2 and the second DC converter 3 will not be overloaded. Since the difference between the first power and the second power tends to 0, the first power is greater than the third power, and the difference between the first power and the third power tends to 0, and the greater the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3, the higher the energy consumption required by the power supply component 1, therefore, in the case of just meeting the power supply needs of the main power distribution circuit 41 and the auxiliary power distribution circuit 42, the rated output power of the first DC converter 2 and the rated output power of the second DC converter 3 can be controlled to avoid additional power consumption of the power supply component 1.

[0072] In some embodiments, the vehicle further comprises a shooting component 109, which is electrically connected to the intelligent driving master control unit 71.

[0073] In this way, the shooting component 109 can be directly connected to the intelligent driving master control unit 71 through the image transmission bus, further assisting the intelligent driving master control unit 71 in control.

[0074] As can be seen from the above embodiment, in the embodiment of the present application, since the power distribution component 4 includes the main power distribution circuit 41 and the auxiliary power distribution circuit 42, the main power distribution circuit 41 is electrically connected to the first DC converter 2 and the first storage battery 5, and the auxiliary power distribution circuit 42 is electrically connected to the second DC converter 3 and the second storage battery 6, so that the power supply system can be powered by the power supply component 1 and the first storage battery 5 and the second storage battery 6, realizing the hardware design requirement of dual power input of the power supply system. Since the control module 01 includes a plurality of control components, the control components in the control module 01 for actively controlling the vehicle are electrically connected to the main power distribution circuit 41, the control components in the control module 01 for automatically controlling the vehicle are electrically connected to the auxiliary power distribution circuit 42, and the control components in the control module 01 for controlling the safety of the vehicle are electrically connected to the main power distribution circuit 41 and the auxiliary power distribution circuit 42, so that only the control components for controlling the safety of the vehicle are designed for power redundancy, and the other control components included in the control module 01 are not designed for power redundancy.

[0075] In summary, the power supply system provided by the embodiments of the present application can ensure that the control components for controlling the safety of the vehicle can continue to be powered by the other power distribution circuit when any one of the main power distribution circuit 41 and the auxiliary power distribution circuit 42 fails, so as to ensure the safety performance of the power supply system for vehicle driving. In addition, by only performing power redundancy design on the control components for controlling the safety of the vehicle, the other control components included in the control module 01 do not need to be designed for power redundancy, which reduces the maximum power provided by the main power distribution circuit 41 and the auxiliary power distribution circuit 42, that is, without increasing the power of the main power distribution circuit 41 and the auxiliary power distribution circuit 42, the normal power supply of the power supply system for vehicle driving can be ensured, thereby saving energy consumption and cost.

The vehicle has the same beneficial effects as the power supply system described above, and the embodiments of the present application will not be described here.
