[0040] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0041] Embodiment One

[0042] The scheme provided in the embodiments of the present application can be applied to any power control system with power supply control capability, such as a control module or device installed with a processing chip, etc.

[0043] With the development of science and technology, vehicles have also been more and more widely used in people's life, which also puts forward higher requirements for the functions of vehicles. Therefore, more and more electrical devices have been gradually added to vehicles to provide more comfort and safety for users. The provision of these functions also makes more and more high-voltage electrical equipment used in vehicles, especially in recent years with the requirement of environmental protection, pure electric vehicles have appeared, which makes various vehicles including electric vehicles use more high-voltage electrical equipment to provide more complex functions and higher performance. Therefore, when the vehicle starts, it is necessary to connect the high-voltage loop between the power supply device provided in the vehicle, such as the battery, to provide the functions required for the normal operation of the vehicle. When the user stops the vehicle and turns off the vehicle, it is necessary to disconnect the high-voltage loop between the high-voltage electrical equipment and the power supply device provided in the vehicle to ensure safety. However, due to the large number of high-voltage electrical equipment provided in the vehicle at present, it is impossible to simultaneously power on or power off these high-voltage electrical equipment. During the sequential power-on or power-off process, if one or more high-voltage electrical equipment fails to power on or power off due to its own failure or power supply loop problem, it will affect other high-voltage electrical equipment, and further cause the power supply loop of the entire vehicle to fail, and even affect the normal operation of the vehicle, causing safety risks.

[0044] To this end, in the embodiments of the present application, a vehicle power-on / off control scheme is proposed, which can generate power-on or power-off sequence information according to a high-voltage electrical equipment list in the vehicle and a power-on instruction when the power-on instruction is received, and perform a delay according to delay information in the information, while performing power-on or power-off on corresponding components according to the power-on or power-off sequence in the information. For example, when a user of the vehicle wants to start the vehicle, the user can issue a vehicle start instruction to the vehicle by pressing a start button of the vehicle, and a vehicle control unit (VCU) of the vehicle can receive the button start signal to trigger it to generate a high-voltage power-on instruction for the entire vehicle. In particular, in the embodiments of the present application, a start button can be provided on the vehicle for the user to press to issue a start signal, or a keyhole can also be provided for the user to insert and rotate a corresponding vehicle key to the predetermined position to issue the start signal.

[0045] In other words, in the embodiments of the present application, the user can be allowed to issue a vehicle start instruction by pressing a corresponding start button or rotating a key inserted into a keyhole on the vehicle by sensing that the user carries a key of the vehicle or the user inserts the key of the vehicle into the keyhole on the vehicle within a predetermined range. In the embodiments of the present application, the vehicle control unit can also obtain relevant signals required for starting, such as a battery state, which can particularly include a loop state of the battery providing high voltage and a charging state of the battery, by corresponding to the user issuing a vehicle start instruction. In addition, the relevant signals can also include current fault information of the vehicle, such as vehicle fault level, and power-off instructions of a battery management system (BMS) for managing the battery, and the like. Therefore, the vehicle control unit can generate and output a high-voltage power-on instruction of the vehicle according to the obtained information, and can further generate a running state of the vehicle control unit.

[0046] Afterwards, the vehicle controller can send the generated high voltage power-on instruction and the running state to the power-on module. The power-on module can generate the power-on sequence information of the high voltage electrical components in the vehicle according to the power-on instruction and the list of high voltage electrical components in the vehicle after receiving the high voltage power-on instruction. In the embodiments of the present application, the power-on sequence information can include the power-on sequence of the high voltage electrical components that need to perform power-on and the delay information when performing power-on operation. In the embodiments of the present application, according to different start instructions given by the user by changing the pressing of the start button or the rotation of the key inserted into the keyhole, different numbers or types of high voltage electrical components in the vehicle can be determined to need to perform power-on operation accordingly. For example, the user starts the vehicle may only want to use the display screen, sound or air conditioner and other high voltage electrical equipment in the vehicle, or the user starts the vehicle is to start the engine or motor to drive the wheels to travel, therefore, such different start requirements correspond to different start instructions, and the user accordingly gives the vehicle controller VCU such different start instructions, so that the vehicle controller can generate the corresponding running state according to the start instruction, such as only power-on state or ready-to-drive state, etc., and can send the state to the power-on module together with the power-on instruction, so that the power-on module can determine the corresponding list of high voltage electrical components that need to be powered on according to the state information, and determine the power-on sequence and corresponding delay information of the high voltage electrical components in the list.

[0047] For example, when the vehicle controller determines that the running state of the vehicle controller is only power-on according to the start instruction given by the user by pressing the button or rotating the key, so that the user uses the display screen, air conditioner and other high voltage electrical components provided in the vehicle, the power-on module can obtain the list of high voltage electrical components of the vehicle only power-on according to the running state, which can be limited to high voltage electrical components that need to perform power-on operation in the only power-on state, such as other components except for high voltage electrical components related to vehicle driving, such as engine related electrical components or drive motor and motor controller and other components, for example, display components, air conditioning components, etc. When the vehicle controller determines that the running state of the vehicle controller is ready-to-drive according to the start instruction given by the user by pressing the button or rotating the key, the power-on module can obtain the list of high voltage electrical components required in the vehicle driving state according to the running state, which can be limited to high voltage electrical components that need to perform power-on operation in the vehicle driving state, such as all high voltage electrical components in the vehicle, including, for example, engine related electrical components or drive motor and motor controller and other components, and display components, air conditioning components, etc.

[0048] In the embodiments of the present application, a plurality of high-voltage electrical component lists can be generated in advance and stored in the storage space in the vehicle in association with the operating state of the vehicle controller. For example, a high-voltage electrical component list required to be powered on in the corresponding scene can be generated in advance for each use scene of the vehicle, such as standby and driving, and stored in the vehicle. Alternatively, each high-voltage electrical component can be specified with its corresponding power-on scene in advance, and the information can be stored in the power-on module, the vehicle controller or other storage space in the vehicle as attribute information of the component, so that the vehicle controller can generate a high-voltage electrical component list according to the power-on scene information of the high-voltage electrical component stored in advance when determining the operating state according to the start instruction issued by the user, and send it to the power-on module according to the request of the power-on module, or the power-on module can generate a corresponding high-voltage electrical component list according to the power-on scene information of the high-voltage electrical component stored in advance when receiving the operating state sent by the vehicle controller, and generate power-on sequence information based on the list.

[0049] The power-on module can perform a delay operation according to the generated delay information, and sequentially power on the high-voltage electrical components in the high-voltage electrical component list in the power-on sequence during the delay operation. For example, in the embodiments of the present application, when the vehicle controller determines that the operating state of the vehicle controller is ready to drive according to the start instruction issued by the user pressing the button or turning the key, the power-on module can obtain the high-voltage electrical component list required for vehicle driving according to the operating state, wherein the high-voltage electrical components required to be powered on for vehicle driving can include: battery management system (BMS), DCDC module, DCAC module and motor electronic control module, and the power-on module can determine the power-on sequence of the high-voltage electrical components according to the attribute information of each component in the list, for example, starting from the battery management system (BMS), then the DCDC module, the DCAC module and the motor electronic control module. In the embodiments of the present application, the power-on sequence can be stored in the vehicle in association with the high-voltage electrical component list, for example, stored in the vehicle controller VCU or stored in the power-on module, or the power-on sequence can also be generated by the power-on module according to the power-on attribute information stored in advance for each high-voltage electrical component in the obtained high-voltage electrical component list.

[0050] After determining the power-on sequence, the power-on module can first perform delay processing according to the generated delay information. For example, a delay time of t can be set, and the timing can be started when the power-on module sends the power-on instruction to the first high-voltage electrical component, such as the BMS, or the timing can be started when the operating status of the vehicle controller VCU is received. Before sending the power-on instruction to the first high-voltage electrical component specified in the power-on sequence, such as the BMS, the high-voltage circuit status of the vehicle is checked first. For example, the current vehicle fault information can be obtained from the vehicle fault inspection module, and when the vehicle fault information indicates that the current high-voltage circuit status is abnormal, such as not allowing high voltage or not allowing to maintain the high-voltage state, the power-on instruction to the first high-voltage electrical component can be immediately suspended and the subsequent inspection feedback of the vehicle fault inspection module can be waited for, and the power-on instruction will not be sent to the first high-voltage electrical component until the current high-voltage circuit status is normal, for example, there is no fault that does not allow high voltage or not allowing to maintain the high-voltage state.

[0051] When the vehicle fault information received by the power-on module indicates that there is no abnormality or fault information that does not allow high voltage to be applied or maintained, the power-on module can issue a power-on instruction to the first high-voltage electrical component until the motor electronic control module feedbacks that the power-on is successful for the last high-voltage electrical component indicated in the power-on sequence, and the timing is terminated, and the timing time is compared with the delay time specified in the delay information. If the delay time specified in the delay information is exceeded, a failure message of power-on failure can be generated as feedback for the power-on instruction issued by the vehicle controller, and if the delay time specified in the delay information is not exceeded, it can be considered that the power-on operation is successful, and a success message of power-on success is generated as feedback for the power-on instruction issued by the vehicle controller. In addition, when the delay timing reaches the delay time specified in the delay information, it can be checked whether the power-on success feedback of the last high-voltage electrical component indicated in the power-on sequence has been received, and if not, a failure message of power-on failure can also be generated as feedback for the power-on instruction issued by the vehicle controller.

[0052] In addition, in an embodiment of the present application, after starting the timing, the power-on module may also directly terminate the current power-on operation when the vehicle fault information indicates that there is an abnormality or fault information that does not allow high voltage to be applied or maintained, and generate power-on failure information as feedback for the vehicle power-on instruction, or when the timing time reaches the delay time specified in the delay information, and the vehicle fault information indicating that there is no abnormality or fault information that does not allow high voltage to be applied or maintained is not received, the power-on module may also generate power-on failure information as feedback for the power-on instruction issued by the vehicle controller.

[0053] In addition, the delay information generated by the power-on module may also include sub-delay information for each high-voltage electrical component in the high-voltage electrical component list. The sub-delay information may be generated based on the attribute information of the corresponding high-voltage electrical component, such as its power-on logic, or may be pre-specified based on experience. Therefore, the power-on module may perform a delay operation according to the sub-delay information corresponding to the BMS when issuing an instruction to the first high-voltage electrical component, such as the BMS, that is, start timing and power on the BMS. In an embodiment of the present application, the power-on module may first obtain the power-on logic and sub-delay information of the high-voltage electrical component when performing a power-on operation on the first high-voltage electrical component, or may generate corresponding sub-delay information according to a pre-set delay rule based on the obtained power-on logic. Afterwards, the power-on module may perform a power-on operation on the BMS according to the power-on logic of the BMS during the execution of the sub-delay operation, and obtain the execution status of the power-on operation fed back by the BMS, such as power-on success or power-on failure. When the BMS reports a successful power-on status, and the power-on module's delay time for executing the BMS power-on operation does not exceed the delay time specified in the sub-delay information, the power-on module can determine that the BMS power-on operation was successful and then repeat similar operations performed on the second high-voltage electrical component in the power-on sequence. For example, the power-on module can continue to obtain the sub-delay information and power-on logic information of the second high-voltage electrical component, namely, the DCAC module, and perform a delay process based on the DCAC sub-delay information, thereby executing the power-on process according to the acquired DCAC module power-on logic information during the delay process. After executing the power-on process, the power-on module can receive a power-on status from the DCAC module. The status can indicate whether the DCAC power-on operation was successful. If the status indicates a successful DCAC power-on operation and the delay time executed by the power-on module does not exceed the delay time specified in the sub-delay information, the power-on module can determine that the second high-voltage electrical component was successfully powered on. And then, it is possible to continue to obtain the sub-delay information and power-on logic information of the third high-voltage electrical component indicated by the power-on sequence information according to the power-on sequence information, and perform the above-mentioned operation on the third high-voltage electrical component similarly to the operation performed on the first high-voltage electrical component and the second high-voltage electrical component. When the execution status of the power-on operation fed back by the third high-voltage electrical component is also a successful power-on and the timing time executed for the third high-voltage electrical component does not exceed the delay time indicated by the sub-delay information of the third high-voltage electrical component, the power-on module can determine that the power-on operation of the third high-voltage electrical component is successful. After determining that the power-on of the third high-voltage electrical component is successful, the power-on module can continue to perform the power-on operation on the fourth high-voltage electrical component in a similar manner.When the execution status of the power-on operation fed back by the fourth high-voltage electrical component is successful power-on, and the timing time of the delay processing performed by the power-on module does not exceed the delay time indicated in the sub-delay information corresponding to the fourth high-voltage electrical component, the power-on module can determine that the power-on operations for all high-voltage electrical components are successful, and feed back the success information to, for example, the vehicle controller, and the vehicle controller can update its operating status based on the information of successful power-on operations of all high-voltage electrical components fed back by the power-on module.

[0054] In addition, during the execution of the above-mentioned power-on operation of the power-on module, when the execution status of the power-on operation fed back by any high-voltage power module is failure, or when the execution status of the power-on operation fed back by the high-voltage power module is success, but the delay timing time executed by the power-on module has exceeded the sub-delay time corresponding to the high-voltage power module, or when the delay timing time executed by the power-on module on the high-voltage power module reaches the corresponding sub-delay time but has not received the execution status information indicating that the power-on operation fed back by the high-voltage power module is successful, the power-on module can determine that the power-on of the corresponding high-voltage power module has failed, and can immediately terminate the execution of the vehicle power-on instruction sent by the vehicle controller, and generate power-on failure information to feed back to the vehicle controller. The vehicle controller can update its working status according to the power-on failure information fed back by the power-on module in a similar manner as above, and can then perform other operations after the vehicle power-on failure, such as generating a warning message to be output through the display screen.

[0055] Furthermore, if the power-on module successfully executes the vehicle power-on command issued by the vehicle control unit (VCU), all required high-voltage electrical components in the vehicle are powered on and operational. Later, if the user completes use of the vehicle and instructs the VCU to power off the vehicle, for example by pressing a button or rotating a key inserted in a key jack, the VCU can generate a power-off command based on the key information and the current operating status, and send the power-off command and the VCU's current operating status to the power-off module.

[0056] After receiving the high-voltage power-off instruction, the power-off module can generate power-off sequence information for the high-voltage electrical components in the vehicle based on the power-off instruction and the list of high-voltage electrical components in the vehicle. In an embodiment of the present application, the power-off sequence information may include the power-off sequence of the high-voltage electrical components that need to be powered off and the delay information when performing the power-off operation. In an embodiment of the present application, based on the different states of the user before the power-off instruction is issued by changing the pressing of the start button or turning the key inserted into the keyhole, it can be determined accordingly that different numbers or types of high-voltage electrical components in the vehicle need to be powered off. For example, when the user presses a button or turns the key, the vehicle is in a power-only state or a ready-to-drive state. The change from such different states to power-off corresponds to different power-off instructions, and accordingly, the user issues such instructions to the vehicle controller VCU, so that the vehicle controller can generate a corresponding operating state according to the vehicle shutdown or shutdown instruction, for example, from the power-on state or the ready-to-drive state to the shutdown state or the shutdown state, and can issue the state and the power-off instruction together to the power-off module, so that the power-off module can determine the corresponding list of high-voltage electrical components that need to be powered off based on the state information and determine the order of powering off and the corresponding delay information based on the high-voltage electrical components in the obtained list. In addition, since the vehicle power-on operation must be completed before the vehicle controller receives the user's shutdown or stop instruction, the vehicle controller can use the previously determined list of high-voltage electrical components involved in the power-on operation or the list of high-voltage electrical components that are already powered on in the current vehicle as the list of high-voltage electrical components involved in the power-off operation.

[0057] Furthermore, the delay information generated by the power-off module may be overall delay information for powering off the high-voltage electrical components determined to need powering off, or may be individual delay information for each of the high-voltage electrical components that need powering off. This delay information may be the same as or different from the delay information determined when powering on the high-voltage electrical components.

[0058] For example, if the vehicle controller's operating state was power-only before the user issued a shutdown or ignition-off command by pressing a button or turning a key, the power-off module can obtain a list of high-voltage electrical components that require powering off in order to switch from power-only to shutdown or ignition-off based on this state change. Alternatively, the list of high-voltage electrical components determined from a previous power-on operation as described above can be used. This list can include high-voltage electrical modules that have already been powered on in the power-only state, such as the display module and the air conditioning module. Furthermore, if the vehicle controller's operating state was ready to drive before the user issued a shutdown or ignition-off command by pressing a button or turning a key, the power-off module can obtain a list of high-voltage electrical components that require powering off in order to switch from the ready-to-drive state to the shutdown or ignition-off based on this state change. Alternatively, the list of high-voltage electrical components determined from a previous power-on operation as described above can be used. This list can include high-voltage electrical components that have already been powered on in the ready-to-drive state, such as all high-voltage electrical components in the vehicle, including, for example, engine-related electrical components, drive motors, motor controllers, display components, air conditioning components, and the like.

[0059] The power-off module can perform a delay operation based on the generated delay information, and during the delay operation, sequentially power off the high-voltage electrical components in the high-voltage electrical component list according to the power-off order. For example, in an embodiment of the present application, when the state before the vehicle controller issues a shutdown or off instruction based on the user pressing a button or turning the key is ready to drive, the power-off module can obtain the list of high-voltage electrical components required for the vehicle to change from ready to drive to shutdown or off based on the change in the operating state. The high-voltage electrical components that need to be powered off may include: a battery management system (BMS), a DCDC module, a DCAC module, and a motor electronic control module, and the power-off module can determine the power-off order of these high-voltage electrical components based on the attribute information of each component in the list. For example, in contrast to the order in which power is executed, it can start from the motor electronic control module, then the DCAC module, the DCDC module, and the battery management system (BMS).

[0060] In an embodiment of the present application, the power-off sequence may be stored in the vehicle in association with the list of high-voltage electrical components, for example, in the vehicle controller VCU or in the power-off module, or the power-off sequence may be generated by the power-off module based on the pre-stored power-off attribute information for each high-voltage electrical component in the obtained list of high-voltage electrical components.

[0061] After determining the power-off sequence, the power-off module may first perform delay processing according to the generated delay information.

[0062] For example, a delay time of t can be set, and the timing can be started when the power-off module sends the power-off instruction to the first high-voltage power-consuming component, such as the motor electronic control module, or the timing can be started when the operating status of the vehicle controller VCU is received, and before the power-off instruction is sent to the first high-voltage power-consuming component specified in the power-off sequence, such as the motor electronic control module, the current high-voltage circuit status of the vehicle is checked first. For example, the current vehicle fault information can be obtained from the vehicle fault check module, and when the vehicle fault information indicates the current

[0063] When the high-voltage circuit state is abnormal, the power-off instruction to the first high-voltage electrical component can be immediately suspended and the subsequent inspection feedback of the 5 vehicle fault inspection module can be waited for. The power-off instruction will not be sent to the first high-voltage electrical component until the current high-voltage circuit state is normal.

[0064] When the vehicle fault information received by the power-off module indicates that there is no abnormality or fault information that does not allow high voltage to be lowered or maintained, the power-off module can send a power-off instruction to the first high-voltage electrical component until the power-off instruction is sent to the first high-voltage electrical component.

[0065] The timing is terminated when the last high-voltage electrical component indicated in the power-off sequence feeds back that the power-off is successful, and the timing time is compared with the delay time specified in the delay information. If the delay time specified in the delay information is exceeded, the power-off operation can be repeated until the power-off is successful. If the delay time specified in the delay information is not exceeded, the power-off operation can be considered successful, and a success message of power-off success is generated as feedback for the power-off instruction issued by the vehicle controller. In addition, the delay time can be checked when the delay time specified in the delay information is reached.

[0066] Check whether the power-off success feedback of the last high-voltage electrical component indicated in the power-off sequence is received, and if not, the power-off operation can be repeated for the high-voltage electrical component that failed to power off until the power-off operations of all high-voltage electrical components are successful.

[0067] In addition, in the embodiment of the present application, after the timing starts, the power-off module can also generate a power-off failure message when the vehicle fault information indicates that there is an abnormality or fault information that does not allow high voltage to be applied or maintained.

[0068] As a feedback to the whole vehicle power-off instruction and continue to check the whole vehicle fault information until there is no abnormality or 0 fault information indicated therein, or when the timing time reaches the delay time specified in the delay information, the whole vehicle fault information indicating that the high voltage is not allowed to be raised or the high voltage is not allowed to be maintained is not received, the power-off module can also generate a failure information of power-off failure as a feedback to the power-off instruction issued by the whole vehicle controller, and continue to check the whole vehicle fault information until there is no abnormality or fault information indicated therein.

[0069] In addition, the delay information generated by the power-off module can also include sub-delay information for each high-voltage electrical component in the high-voltage electrical component list, which can be generated according to the attribute information of the corresponding high-voltage electrical component, such as its power-off logic, or can be pre-specified according to experience. Therefore, the power-off module can delay the operation according to the corresponding sub-delay information of the first high-voltage electrical component, such as the motor control module, when issuing a command to the motor control module, that is, starting the timing and performing the power-off operation on the motor control module. In the embodiments of the present application, the power-off module can first obtain the power-off logic and the sub-delay information of the first high-voltage electrical component when performing the power-off operation on the first high-voltage electrical component, or can generate the corresponding sub-delay information according to the pre-set delay rule according to the obtained power-off logic. Then, the power-off module can perform the power-off operation on the motor control module according to its power-off logic during the execution of the sub-delay operation, and obtain the feedback execution state of the power-off operation, such as power-off success or power-off failure. When the execution state of the power-off operation fed back by the motor control module is power-off success, and the delay time of the power-off operation performed by the power-off module on the motor control module does not exceed the delay time specified in the sub-delay information, the power-off module can determine that the power-off operation of the motor control module is successfully executed and further repeat the similar operation as described above for the second high-voltage electrical component in the power-off sequence. For example, the power-off module can continue to obtain the sub-delay information and power-off logic information of the second high-voltage electrical component, that is, the DCDC module, and perform delay processing according to the sub-delay information of the DCDC, so as to perform power-off processing according to the obtained power-off logic information of the DCDC module during the delay processing. After performing the power-off processing, the execution state of the power-off operation fed back by the DCDC module can be received, which can indicate whether the power-off operation of the DCDC is successful, and when the execution state indicates that the power-off operation of the DCDC is successful and the delay time of the power-off module does not exceed the delay time specified in the sub-delay information, the power-off module can determine that the power-off of the second high-voltage electrical component is successful. And further, it can continue to obtain the sub-delay information and power-off logic information of the third high-voltage electrical component indicated by the power-off sequence information according to the power-off sequence, and perform the above operation on the third high-voltage electrical component similar to the operation performed on the first high-voltage electrical component and the second high-voltage electrical component. When the execution state of the power-off operation fed back by the third high-voltage electrical component is also power-off success and the timing time performed on the third high-voltage electrical component does not exceed the delay time specified in the sub-delay information of the third high-voltage electrical component, the power-off module can determine that the power-off operation of the third high-voltage electrical component is successful. After determining that the power-off of the third high-voltage electrical component is successful, the power-off module can continue to perform the power-off operation on the fourth high-voltage electrical component in a similar manner.When the execution state of the power-off operation fed back by the fourth high-voltage electrical component is power-off success, and the timing time of the delay processing performed by the power-off module does not exceed the delay time indicated in the sub-delay information corresponding to the fourth high-voltage electrical component, the power-off module can determine that the power-off operation of all high-voltage electrical components is successful, feed back the success information to, for example, the vehicle controller, and the vehicle controller can update its operating state according to the information fed back by the power-off module that the power-off operation of all high-voltage electrical components is successful.

[0070] In addition, during the above power-off operation execution process of the power-off module, when the execution state of the power-off operation fed back by any one high-voltage electrical component is failure, or when the execution state of the power-off operation fed back by the high-voltage electrical component is success, but the timing time of the delay processing performed by the power-off module has exceeded the sub-delay time corresponding to the high-voltage electrical component, or when the timing time of the delay processing performed by the power-off module reaches the corresponding sub-delay time but no execution state information indicating that the power-off operation fed back by the high-voltage electrical component is successful is received, the power-off module can determine that the power-off of the corresponding high-voltage electrical component fails, and can generate power-off failure information and feed it back to the vehicle controller, while continuing to repeat the power-off processing of the high-voltage electrical component until the power-off state of the high-voltage electrical component is determined to be successful. The vehicle controller can update its operating state according to the power-off failure information fed back by the power-off module in a similar manner as above, and can further perform other operations after the vehicle power-off fails, such as generating warning information for output through the display screen.

[0071] The vehicle power-on and power-off control scheme provided by the embodiments of the present application can generate vehicle power-on or power-off sequence information according to the vehicle power-on or power-off instruction and the power-on and power-off list of the vehicle, perform delay operation according to the delay information in the power-on or power-off sequence information to perform power-on or power-off operation on the corresponding high-voltage electrical component in the power-on or power-off sequence during the delay operation, obtain the power-on or power-off state information fed back by each high-voltage electrical component indicating whether the power-on or power-off operation of the corresponding component is completed, and determine the execution state of the power-on or power-off instruction according to the state information and the delay state of the delay operation, so that the sequence information can be generated when the power-on and power-off instruction is received, and the power-on and power-off can be determined to be successful according to the delay state and the power-on and power-off completion of each component, which can adjust the power-on and power-off sequence according to the change of the high-voltage electrical component in the vehicle when adapting different vehicles, perform power-on and power-off operation according to the corresponding power-on and power-off logic during execution, and can also directly determine the execution state of the power-on and power-off instruction of the entire vehicle when any power-on and power-off operation of the high-voltage electrical component is abnormal during the delay period, so that the power-on and power-off state of each component can be quickly responded, and the safety of the vehicle and the high-voltage electrical component therein is improved.

[0072] The above embodiments are descriptions of the technical principles and exemplary application frameworks of the embodiments of the present application. The specific technical solutions of the embodiments of the present application are described in further detail through multiple embodiments.

[0073] Embodiment Two

[0074] Figure 1 A flowchart of the vehicle power-on control method embodiments provided in the present application is shown in FIG. 1. The execution subject of the method can be various terminals or devices with power control capabilities, or devices or chips integrated on these devices. As shown in FIG. 1, the vehicle power-on control method includes the following steps: Figure 1

[0075] S101, receiving a vehicle power-on instruction.

[0076] In step S101, the vehicle power-on instruction sent by, for example, the vehicle controller VCU can be received by, for example, the power-on module in the vehicle. The vehicle power-on instruction can be generated according to the user's operation of the vehicle start button or the rotating operation using the key, and can be used to instruct the power-on operation of each high-voltage electrical component in the vehicle.

[0077] For example, in the embodiments of the present application, the vehicle controller VCU in the vehicle can allow the user to receive the vehicle start instruction by pressing the corresponding start button or rotating the key inserted into the keyhole of the vehicle through sensing the key of the vehicle carried by the user or the key of the vehicle inserted into the keyhole of the vehicle within a predetermined range. The vehicle controller can also obtain the relevant signals required for starting, such as the battery state, by corresponding to the user's vehicle start instruction. The battery state can specifically include the loop state of the battery providing high voltage and the charging state of the battery. In addition, the relevant signals can also include the current fault information of the vehicle, such as the vehicle fault level, the power-off instruction of the battery management system (BMS) for managing the battery, and the like. Therefore, the vehicle controller can generate and output the high-voltage power-on instruction of the vehicle according to the obtained information, and can further generate the running state of the vehicle controller. Therefore, in step S101, the vehicle power-on instruction and the running state generated from the vehicle controller can be received.

[0078] S102, generating vehicle power-on sequence information according to the vehicle power-on instruction and the vehicle power component list.

[0079] ​In step S102, the power-on module may similarly generate vehicle power-on sequence information based on the vehicle power-on instruction received in step S101 and a list of components in the vehicle that need to be powered on, such as a list of high-voltage electrical components. In an embodiment of the present application, the vehicle power-on component list may include component information of each high-voltage electrical component in the vehicle, and the vehicle power-on sequence information may include the power-on sequence and delay information of each high-voltage electrical component in the vehicle.

[0080] For example, based on the different start instructions issued by the user by changing the start button or turning the key inserted into the keyhole, it can be determined that different numbers or types of high-voltage electrical components in the vehicle need to be powered on. For example, the user may start the vehicle only to use high-voltage electrical equipment such as the display screen, audio, or air conditioner in the vehicle, or the user may start the vehicle to start the engine or motor to drive the wheels. Therefore, such different start requirements correspond to different start instructions, and the user can issue the corresponding start instructions to the vehicle control unit (VCU) through such different operations, so that the vehicle control unit can generate a corresponding operating state based on the start instruction, such as a power-only state or a ready-to-drive state, etc., and can receive this state and the power-on instruction in step S101. Therefore, the power-on module can determine a list of corresponding high-voltage electrical components that need to be powered on based on the state information in step S102 and determine the order of powering on the high-voltage electrical components in the obtained list and the corresponding delay information. The delay information generated in step S102 may be overall delay information for powering on the determined high-voltage electrical components that need to be powered on, or may be individual delay information for each of the high-voltage electrical components that need to be powered on.

[0081] For example, when the VCU determines that the operating state of the VCU is "power-on only" based on a startup instruction issued by a user by pressing a button or turning a key, so that the user can use high-voltage electrical components such as a display screen and air conditioning provided in the vehicle, then in step S102, a list of high-voltage electrical components of the vehicle that are "power-on only" can be obtained based on this operating state. The list of high-voltage electrical components that require power-on in the "power-on only" state can be defined as components other than high-voltage electrical components related to vehicle driving, such as engine-related electrical components or drive motors and motor controllers, such as display components and air conditioning components. Furthermore, when the VCU determines that the operating state of the VCU is "ready to drive" based on a startup instruction issued by a user by pressing a button or turning a key, a list of high-voltage electrical components required for vehicle driving can be obtained based on this operating state. The list of high-voltage electrical components that require power-on in the vehicle's driving state can be defined as components such as all high-voltage electrical components in the vehicle, including components such as engine-related electrical components or drive motors and motor controllers, as well as display components and air conditioning components.

[0082] In an embodiment of the present application, a plurality of lists of high-voltage electrical components can be pre-generated and stored in a storage space in the vehicle in association with the operating status of the vehicle controller. For example, a list of high-voltage electrical components that need to be powered on in corresponding scenarios can be pre-generated for use scenarios such as the vehicle being powered on only in standby mode and driving, and stored in the vehicle. Alternatively, a corresponding power-on scenario can be specified for each high-voltage electrical component in advance and the information can be pre-stored in the power-on module or the vehicle controller or other storage space in the vehicle as the attribute information of the component, so that when the operating status is determined according to the startup instruction issued by the user, a list of high-voltage electrical components can be generated based on the power-on scenario information of the high-voltage electrical components stored in advance, and sent to the power-on module according to the request of the power-on module, or in step S102, when the operating status sent by the vehicle controller is received, a corresponding list of high-voltage electrical components can be generated based on the power-on scenario information of the high-voltage electrical components stored in advance, and power-on sequence information can be generated based on the list.

[0083] S103 , performing a delay operation according to the delay information, so as to perform a power-on operation on each high-voltage electrical component in the vehicle power-on component list according to the vehicle power-on sequence information during the delay operation.

[0084] S104: Obtain power-on status information fed back by each high-voltage electrical component.

[0085] In step S103 , a delay operation may be performed according to the delay information generated in step S102 , and during the delay operation, corresponding high-voltage electrical components may be powered on according to the power-on sequence generated in step S102 .

[0086] For example, in an embodiment of the present application, when the vehicle controller determines that the operating state of the vehicle controller is ready to drive according to the start-up instruction issued by the user by pressing a button or turning a key, the power-on module can obtain a list of high-voltage electrical components required for the vehicle's driving state based on the operating state, wherein the high-voltage electrical components that need to be powered on for the vehicle to drive are defined to include: a battery management system (BMS), a DCDC module, a DCAC module, and a motor electronic control module, and the power-on module can determine the power-on order of these high-voltage electrical components based on the attribute information of each component in the list, for example, starting from the battery management system (BMS), then the DCDC module, the DCAC module, and the motor electronic control module. In an embodiment of the present application, the power-on order can be stored in the vehicle in association with the high-voltage electrical component list, such as in the vehicle controller VCU or in the power-on module, or the power-on order can also be generated by the power-on module based on the power-on attribute information pre-stored for each high-voltage electrical component in the obtained high-voltage electrical component list.

[0087] In step S103, a delay time of t can be set, and the timing can be started when the power-on instruction is issued to the first high-voltage electrical component, or the timing can be started when the operating status of the vehicle controller VCU is received, and before the power-on instruction is issued to the first high-voltage electrical component specified in the power-on sequence, the high-voltage circuit status of the vehicle is checked first. For example, the current vehicle fault information can be obtained from the vehicle fault inspection module, and when the vehicle fault information indicates that the current high-voltage circuit status is abnormal, such as not allowing high voltage or not allowing to maintain the high-voltage state, the power-on instruction to the first high-voltage electrical component can be immediately suspended and the subsequent inspection feedback of the vehicle fault inspection module can be waited for. The power-on instruction is not issued to the first high-voltage electrical component until the current high-voltage circuit status is normal, such as there is no fault that does not allow high voltage or not allowing to maintain the high-voltage state, and the power-on status information of the corresponding high-voltage electrical component is obtained in step S104. The power-on status information can indicate whether the power-on operation of the corresponding high-voltage electrical component is completed.

[0088] S105 , determining an execution state of the vehicle power-on instruction according to the power-on state information and the delay state of the delay operation.

[0089] In step S105, the power-on module stops timing when the last high-voltage electrical component indicated in the power-on sequence feeds back that the power is on successfully, and compares the timing time with the delay time specified in the delay information. If the delay time specified in the delay information is exceeded, a failure message of power-on failure can be generated as feedback for the power-on instruction issued by the vehicle controller. If the delay time specified in the delay information is not exceeded, the power-on operation can be considered successful, and a success message of power-on success can be generated as feedback for the power-on instruction issued by the vehicle controller. In addition, when the delay timing reaches the delay time specified in the delay information, it can be checked whether the power-on success feedback of the last high-voltage electrical component indicated in the power-on sequence has been received, and if not, a failure message of power-on failure can also be generated as feedback for the power-on instruction issued by the vehicle controller.

[0090] In step S105, after starting the timing, the power-on module may also directly terminate the current power-on operation when the vehicle fault information indicates that there is an abnormality or fault information that does not allow high voltage to be applied or maintained, and generate power-on failure information as feedback for the vehicle power-on instruction, or when the timing time reaches the delay time specified in the delay information, and the vehicle fault information indicating that there is no abnormality or fault information that does not allow high voltage to be applied or maintained is not received, the power-on module may also generate power-on failure information as feedback for the power-on instruction issued by the vehicle controller.

[0091] In addition, the delay information generated by the power-on module may also include sub-delay information for each high-voltage electrical component in the high-voltage electrical component list. This sub-delay information may be generated based on the attribute information of the corresponding high-voltage electrical component, such as its power-on logic, or may be pre-specified based on experience. Therefore, when issuing an instruction to the first high-voltage electrical component in step S103, a delay operation may be performed according to the sub-delay information corresponding to the component, i.e., timing may be started and the component may be powered on.

[0092] When the first high-voltage electrical component is powered on in step S103, the power-on logic and its sub-delay information of the high-voltage electrical component can be first obtained, or the corresponding sub-delay information can be generated according to the obtained power-on logic according to the pre-set delay rule. Afterwards, the power-on module can perform a power-on operation on the first high-voltage electrical component according to the power-on logic during the execution of the sub-delay operation, and obtain the execution status of the power-on operation fed back by the first high-voltage electrical component in step S104, such as power-on success or power-on failure. When the execution status of the power-on operation fed back by the first high-voltage electrical component is power-on success, and the delay timing for the power-on operation of the first high-voltage electrical component does not exceed the delay time specified in its sub-delay information, the power-on module can determine that the power-on operation of the first high-voltage electrical component is executed successfully and then repeat the operation similar to the above operation performed on the BMS for the second high-voltage electrical component in the power-on sequence. For example, the sub-delay information and power-on logic information of the second high-voltage electrical component can be continuously obtained in step S103, and delay processing can be performed according to the obtained sub-delay information of the component, so that the power-on processing can be performed according to the obtained power-on logic information during the delay processing. Of course, in an embodiment of the present application, the logic information and delay information of all high-voltage electrical components that need to be powered on indicated in the power-on component list can also be obtained at one time in step S103, and used one by one in step S104.

[0093] In step S104, the execution state of the power-on operation after the corresponding high-voltage electrical component performs the power-on process can be acquired, which can indicate whether the power-on operation of the component is successful, and when the execution state indicates that the power-on operation is successful and the delay timing time performed by the power-on module does not exceed the delay time indicated in the sub-delay information, in step S105, it can be determined that the power-on of the second high-voltage electrical component is successful. And further, according to the power-on sequence, the sub-delay information and the power-on logic information of the third high-voltage electrical component indicated by the power-on sequence information can be acquired and the above-mentioned operations can be performed for the third high-voltage electrical component similar to the operations performed for the first and second high-voltage electrical components. When the execution state of the power-on operation fed back by the third high-voltage electrical component is also power-on successful and the timing time performed by the power-on module for the third high-voltage electrical component does not exceed the delay time indicated in the sub-delay information of the third high-voltage electrical component, the power-on module can determine that the power-on operation of the third high-voltage electrical component is successful. After determining that the power-on of the third high-voltage electrical component is successful, the power-on module can continue to perform the power-on operation for the fourth high-voltage electrical component similarly. When the execution state of the power-on operation fed back by the fourth high-voltage electrical component is power-on successful, and the timing time of the delay processing performed by the power-on module does not exceed the delay time indicated in the sub-delay information corresponding to the fourth high-voltage electrical component, the power-on module can determine that the power-on operation for all high-voltage electrical components is successful, and feedback the success information to, for example, the vehicle controller, and the vehicle controller can update its running state according to the information fed back by the power-on module that the power-on operation of all high-voltage electrical components is successful.

[0094] In addition, when the execution state of the power-on operation fed back by any one of the high-voltage electrical modules is failure in step S104, or when the execution state of the power-on operation fed back by the high-voltage electrical module is success in step S104, but the delay timing time performed by the power-on module has exceeded the sub-delay time corresponding to the high-voltage electrical module, or when the delay timing time performed by the power-on module for the high-voltage electrical module reaches the corresponding sub-delay time but no execution state information indicating that the power-on operation of the high-voltage electrical module is successful is received, in step S105, it can be determined that the power-on of the corresponding high-voltage electrical module fails, and the execution of the vehicle power-on instruction sent by the vehicle controller can be terminated immediately, and the power-on failure information can be generated and fed back to the vehicle controller. The vehicle controller can update its working state according to the power-on failure information fed back by the power-on module similarly as above, and further can perform other operations after the vehicle power-on failure, for example, generate warning information to be output through the display screen.

[0095] The vehicle power-on control method provided in the embodiment of the present application can generate vehicle power-on sequence information based on the vehicle power-on instruction and the vehicle power-on list, and perform a delay operation based on the delay information in the power-on sequence information to perform a power-on operation on the corresponding high-voltage electrical components in accordance with the power-on sequence during the delay operation. At the same time, the power-on status information indicating whether the power-on operation of the corresponding component is completed is obtained from each high-voltage electrical component, and the execution status of the power-on instruction is determined based on the status information and the delay status of the delay operation. Therefore, when the power-on instruction is received, the sequence information can be generated and whether the power-on is successful can be judged based on the delay status and the power-on completion status of each component. In this way, when adapting to different vehicles, the power-on sequence can be adjusted according to the changes in the high-voltage electrical components in the vehicle, and the power-on operation can be performed according to the corresponding power-on logic during the execution period. Moreover, during the delay period, no matter which high-voltage electrical component has an abnormal power-on or power-off operation, the execution status of the power-on instruction of the entire vehicle can be directly determined, thereby being able to quickly respond to the power-on status of each component and improving the safety of the vehicle and the high-voltage electrical components therein.

[0096] Example 3

[0097] Figure 2 This is a flow chart of an embodiment of the vehicle power-off control method provided by this application. The execution subject of this method can be various terminals or devices with power control capabilities, or devices or chips integrated on these devices. Figure 2 As shown, the vehicle power-off control method includes the following steps:

[0098] S201, receiving a vehicle power-off instruction.

[0099] In step S201, when the vehicle is already started, a vehicle power-off command issued by the user through the vehicle controller by, for example, pressing a button or rotating a knob can be received. The vehicle power-off command can be used to instruct the power-off operation of various high-voltage electrical components in the vehicle.

[0100] For example, if a vehicle power-on command issued by the vehicle control unit (VCU) is successfully executed, all required high-voltage electrical components in the vehicle are powered on and put into use. When the user has completed using the vehicle and instructs the VCU to power off the vehicle, for example by pressing a button or rotating a key inserted in a key slot, the VCU can generate a power-off command based on the key information and the current operating status, and send the power-off command and the VCU's current operating status to the power-off module.

[0101] S202 : Generate vehicle power-off sequence information according to the vehicle power-off instruction and the vehicle power-off component list.

[0102] In step S202, the power-off module may generate vehicle power-off sequence information based on the vehicle power-off instruction received from the vehicle controller in step S201 and further combined with the vehicle power-off component list. For example, the vehicle power-off component list may include component information of each high-voltage electrical component in the vehicle that has been successfully powered on, and the vehicle power-off sequence information may include the power-off sequence and delay information of each high-voltage electrical component in the vehicle.

[0103] For example, after receiving the vehicle power-off instruction in step S201, the power-off module can generate power-off sequence information for the high-voltage electrical components in the vehicle based on the power-off instruction and the list of high-voltage electrical components in the vehicle in step S202. In an embodiment of the present application, the power-off sequence information may include the power-off sequence of the high-voltage electrical components that need to be powered off and the delay information when performing the power-off operation. For example, depending on the different states of the user before the power-off instruction is issued by changing the pressing of the start button or turning the key inserted into the key socket, it can be determined accordingly that different numbers or types of high-voltage electrical components in the vehicle need to be powered off. For example, when the user presses a button or turns a key, the vehicle is in a power-only state or a state that has just finished driving. These different states correspond to different power-off instructions, and the user issues such instructions to the vehicle controller (VCU). The vehicle controller can then generate a corresponding operating state based on the vehicle shutdown or shutdown instruction, for example, from a power-on state or a state that has just finished driving to a power-off state or a shutdown state. The state and the power-off instruction can then be sent to the power-off module together. The power-off module can then determine the corresponding list of high-voltage electrical components that need to be powered off in step S202 based on the state information and determine the order in which they should be powered off and the corresponding delay information based on the high-voltage electrical components in the obtained list. In addition, since the vehicle power-on operation must have been completed before the vehicle controller receives the user's shutdown or stop instruction, the vehicle controller can use the previously determined list of high-voltage electrical components involved in the power-on operation or the list of high-voltage electrical components that are already powered on in the current vehicle as the list of high-voltage electrical components involved in the power-off operation.

[0104] In addition, the delay information generated by the power-off module in step S202 can be the overall delay information for powering off the high-voltage electrical components determined to need to be powered off, or it can be the individual delay information for each of the high-voltage electrical components that need to be powered off. This delay information can be the same as or different from the delay information determined when the high-voltage electrical components are powered on.

[0105] For example, if the vehicle controller's operating state was power-only before the user issued a shutdown or ignition-off command by pressing a button or turning a key, the power-off module can obtain a list of high-voltage electrical components that require powering off in order to switch from power-only to shutdown or ignition-off based on this state change. Alternatively, the list of high-voltage electrical components determined from a previous power-on operation as described above can be used. This list can include high-voltage electrical modules that have already been powered on in the power-only state, such as the display module and the air conditioning module. Furthermore, if the vehicle controller's operating state was ready to drive before the user issued a shutdown or ignition-off command by pressing a button or turning a key, the power-off module can obtain a list of high-voltage electrical components that require powering off in order to switch from the ready-to-drive state to the shutdown or ignition-off based on this state change. Alternatively, the list of high-voltage electrical components determined from a previous power-on operation as described above can be used. This list can include high-voltage electrical components that have already been powered on in the ready-to-drive state, such as all high-voltage electrical components in the vehicle, including, for example, engine-related electrical components, drive motors, motor controllers, display components, air conditioning components, and the like.

[0106] S203 , performing a delay operation according to the delay information, so as to perform a power-off operation on each high-voltage electrical component in the vehicle power-off component list according to the vehicle power-off sequence information during the delay operation.

[0107] S204: Obtain power-off status information fed back by each high-voltage electrical component.

[0108] In step S203, a delay operation can be performed based on the delay information generated in step S202, so that during the delay operation, the power-off operation can be performed on each high-voltage electrical component according to the vehicle power-off sequence determined in step S202, and in step S204, the power-off status information fed back from the high-voltage electrical component performing the power-off operation can be received. The power-off status information can indicate whether the power-off operation of the corresponding high-voltage electrical component is completed. When the power-off status information received in step S204 indicates that the power-off operation of the high-voltage electrical component has failed, steps S203 and S204 can be repeated to repeat the power-off operation for the high-voltage electrical component.

[0109] S205 , when the power-off status information fed back by each high-voltage electrical component indicates that the corresponding power-off operation is completed within the execution time of the delay operation, generating vehicle power-off completion information as feedback for the vehicle power-off instruction.

[0110] For example, the power-off module can first perform a fault high-voltage power-off check based on the vehicle fault information in step S203 to determine whether the received vehicle fault information indicates that there is no abnormality or fault information that does not allow high voltage to be lowered or maintained. After that, a power-off instruction can be issued to the first high-voltage electrical component until the last high-voltage electrical component indicated in the power-off sequence is fed back that the power-off is successful, and the timing is terminated, and the timing time is compared with the delay time specified in the delay information. If the delay time specified in the delay information is exceeded, the power-off operation can be repeated until the power-off is successful. If the delay time specified in the delay information is not exceeded, the power-off operation can be considered successful, and a success message of power-off success is generated as feedback for the power-off instruction issued by the vehicle controller. In addition, when the delay timing reaches the delay time specified in the delay information, it can be checked whether the power-off success feedback of the last high-voltage electrical component indicated in the power-off sequence has been received, and if not, the power-off operation can be repeated for the high-voltage electrical component that failed to power off until the power-off operations of all high-voltage electrical components are successful.

[0111] In addition, in an embodiment of the present application, after the timing starts in step S203, the power-off module can also generate power-off failure information as feedback to the vehicle power-off instruction when the vehicle fault information indicates that there is an abnormality or fault information that does not allow high voltage to be applied or maintained, and continue to check the vehicle fault information until it indicates that there is no abnormality or fault information, or when the timing time reaches the delay time specified in the delay information, the vehicle fault information indicating that there is no abnormality or fault information that does not allow high voltage to be applied or maintained has not been received, the power-off module can also generate power-off failure information as feedback to the power-off instruction issued by the vehicle controller, and continue to check the vehicle fault information until it indicates that there is no abnormality or fault information.

[0112] Furthermore, the delay information generated by the power-off module in step S202 may also include sub-delay information for each high-voltage component in the high-voltage component list. This sub-delay information may be generated based on the corresponding high-voltage component's attributes, such as its power-off logic, or may be pre-specified based on experience. Therefore, when issuing a command to the first high-voltage component, the power-off module may perform a delay operation based on the corresponding sub-delay information, i.e., begin timing and power off the motor electronic control module.

[0113] In step S203, the power-off module may first obtain the power-off logic and sub-delay information of the high-voltage electrical component when performing a power-off operation on the first high-voltage electrical component, or may generate corresponding sub-delay information according to the obtained power-off logic and a pre-set delay rule. Afterwards, the power-off module may perform a power-off operation on the first high-voltage electrical component according to the power-off logic of the first high-voltage electrical component during the execution of the sub-delay operation, and obtain the execution status of the power-off operation fed back by the first high-voltage electrical component, such as power-off success or power-off failure. When the execution status of the power-off operation fed back by the first high-voltage electrical component is power-off success, and the delay timing of the power-off operation performed by the power-off module on the first high-voltage electrical component does not exceed the delay time specified in its sub-delay information, the power-off module may determine that the power-off operation of the first high-voltage electrical component is executed successfully and then repeat the above-mentioned operation similar to the above-mentioned operation performed on the first high-voltage electrical component on the second high-voltage electrical component in the power-off sequence. For example, the power-off module can continue to obtain the sub-delay information and power-off logic information of the second high-voltage electrical component, and perform delay processing according to the sub-delay information of the second high-voltage electrical component, so as to perform the power-off processing according to the acquired power-off logic information of the second high-voltage electrical component during the delay processing. After the power-off processing is performed, the execution status of the power-off operation fed back by the second high-voltage electrical component can be received. The execution status can indicate whether the power-off operation of the second high-voltage electrical component is successful. When the execution status indicates that the power-off operation of the second high-voltage electrical component is successful and the delay timing time executed by the power-off module does not exceed the delay time indicated in the sub-delay information, the power-off module can determine that the power-off of the second high-voltage electrical component is successful. And then, the sub-delay information and power-off logic information of the third high-voltage electrical component indicated by the power-off sequence information can be continued according to the power-off sequence, and the above-mentioned operations can be performed on the third high-voltage electrical component similar to the operations performed on the first and second high-voltage electrical components. When the power-off operation status fed back by the third high-voltage electrical component indicates that the power-off operation was successful and the timed execution time for the third high-voltage electrical component does not exceed the delay time indicated by the sub-delay information of the third high-voltage electrical component, the power-off module can determine that the power-off operation of the third high-voltage electrical component is successful. After determining that the power-off operation of the third high-voltage electrical component is successful, the power-off module can continue to similarly perform the power-off operation on the fourth high-voltage electrical component.When the execution status of the power-off operation fed back by the fourth high-voltage electrical component is that the power-off is successful, and the timing time of the delay processing performed by the power-off module does not exceed the delay time indicated in the sub-delay information corresponding to the fourth high-voltage electrical component, the power-off module can determine that the power-off operations for all high-voltage electrical components are successful, and feed back the success information to, for example, the vehicle controller, and the vehicle controller can update its operating status based on the information that the power-off operations of all high-voltage electrical components are successful fed back by the power-off module.

[0114] In addition, during the execution of the above-mentioned power-off operation of the power-off module, when the execution status of the power-off operation fed back by any high-voltage power module is failure, or when the execution status of the power-off operation fed back by the high-voltage power module is success, but the delay timing time executed by the power-off module has exceeded the sub-delay time corresponding to the high-voltage power module, or when the delay timing time executed by the power-off module on the high-voltage power module reaches the corresponding sub-delay time but has not received the execution status information indicating that the power-off operation fed back by the high-voltage power module is successful, the power-off module can determine that the power-off of the corresponding high-voltage power module has failed, and can generate power-off failure information to feed back to the vehicle controller, and continue to repeat the power-off processing of the high-voltage power component until it is confirmed that the power-off status of the high-voltage power component is success. The vehicle controller can update its working status according to the power-off failure information fed back by the power-off module in a similar manner as above, and can then perform other operations after the vehicle power-off failure, such as generating a warning message to be output through the display screen.

[0115] The vehicle power-off control method provided in the embodiment of the present application can generate vehicle power-off sequence information according to the vehicle power-off instruction and the vehicle power-off list, and perform a delay operation according to the delay information in the power-off sequence information to perform a power-off operation on the corresponding high-voltage electrical components according to the power-off sequence during the delay operation, and at the same time obtain the power-off status information fed back by each high-voltage electrical component indicating whether the power-off operation of the corresponding component is completed, and determine the execution status of the power-off instruction according to the status information and the delay status of the delay operation, so that the sequence information can be generated when the power-off instruction is received and the execution status can be determined according to the delay status. And the power-off completion status of each component is used to determine whether the power-off is successful, and when the power-off fails, the power-off operation is repeated for the corresponding high-voltage electrical component. In this way, when adapting to different vehicles, the power-off sequence can be adjusted according to the changes in the high-voltage electrical components in the vehicle, and the power-off operation can be performed according to the corresponding power-off logic during execution. Moreover, during the delay period, no matter which high-voltage electrical component has an abnormal power-off operation, the execution status of the power-off instruction of the entire vehicle can be directly determined, so that the power-off status of each component can be responded to quickly, thereby improving the safety of the vehicle and the high-voltage electrical components therein.
