[0032] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0033] In an autonomous vehicle, the vehicle power supply can be affected by the switch level of the vehicle. When the level is high, the vehicle power supply is turned on, and when the level is low, the vehicle power supply is turned off. For example, after the driver gets in the car and turns on the one-touch start button, a constant voltage of about 13V will appear on the cable of the vehicle power supply. After the MCU (Microcontroller Unit) detects this voltage, it turns on the vehicle power supply, and the vehicle power supply will supply power to each unit module on the vehicle; when the one-touch start button is turned off, 0V voltage appears on the cable. After the MCU detects this voltage, it sends a shutdown command to each unit module, exits all currently running applications, and then cuts off the vehicle power supply.

[0034] However, when the autonomous driving system has a cable connection problem, for example, the cable is abnormally disconnected, the vehicle power supply will also be shut down. If the vehicle is currently performing an autonomous driving task, a very serious traffic accident may occur. Alternatively, when the cable is abnormally disturbed, for example, the cable surface is damaged and contacts other metal parts of the vehicle body, the voltage on the cable may also become low for a period of time, causing the autonomous driving system to shut down abnormally. Or, when a logical error occurs inside the MCU, the shutdown command is mistakenly issued, causing an abnormal shutdown.

[0035] In other words, the current control of the vehicle's power supply is not stable and reliable enough. When some unexpected fault conditions occur, the vehicle's automatic driving system may be abnormally shut down, causing serious consequences for driving safety.

[0036] The present disclosure provides a control method, device, electronic device and storage medium for a vehicle power supply, which are applied to the field of autonomous driving in the field of artificial intelligence to achieve stable and reliable control of the vehicle power supply.

[0037] It should be noted that the data in this embodiment is not targeted at a specific user and cannot reflect the personal information of a specific user. It should be noted that the data in this embodiment comes from a public data set.

[0038] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0039] In order to enable readers to more deeply understand the implementation principle of the present disclosure, the following Figure 1-Figure 9 The embodiment is further refined.

[0040] Figure 1 FIG. 1 is a flow chart of a method for controlling a vehicle power supply according to an embodiment of the present disclosure, and the method can be executed by a control device for a vehicle power supply. Figure 1 As shown, the method comprises the following steps:

[0041] S101. In response to a request to shut down the vehicle power supply, obtain first driving state information of the vehicle; wherein the first driving state information represents the current driving state of the vehicle obtained by a main computing unit in the vehicle.

[0042] For example, a vehicle is equipped with an onboard computing platform, which is the hardware core for realizing the vehicle's autonomous driving function. The reliability and stability of the power supply in the onboard computing platform will directly affect driving safety. If there is a power problem or unexpected shutdown, the vehicle may be directly out of control.

[0043] The vehicle computing platform can be deployed with MCU, vehicle power supply, main computing unit, and auxiliary computing unit, that is, the vehicle is deployed with MCU, vehicle power supply, main computing unit, and auxiliary computing unit, etc. The MCU is used to manage the power on and off of the vehicle, and the vehicle power supply is used to power the vehicle, which is the main power supply of the vehicle computing platform. The main computing unit is used to control the automatic driving function of the vehicle, and the auxiliary computing unit is the backup computing unit of the main computing unit. When the main computing unit fails, the auxiliary computing unit can take over the work of the main computing unit.

[0044] When the vehicle power supply needs to be cut off, the vehicle responds to the shutdown request for the vehicle power supply. Specifically, the MCU in the vehicle may respond to the shutdown request for the vehicle power supply. For example, the user touches the IGN (Ignition) off button on the vehicle and issues a shutdown request. After responding to the shutdown request of the vehicle power supply, the main computing unit and the auxiliary computing unit may be controlled to stop working. The main computing unit may be controlled to stop working first, and then the auxiliary computing unit may be controlled to stop working. When the main computing unit is controlled to stop working, the first driving state information of the vehicle may be obtained through the main computing unit. The first driving state information represents the current driving state of the vehicle obtained by the main computing unit. For example, the driving state may refer to the vehicle speed, driving direction, window switch state, etc. The MCU may instruct the main computing unit to obtain the first driving state information. After receiving the instruction of the MCU, the main computing unit obtains the current driving state information of the vehicle in real time as the first driving state information. The main computing unit may send the first driving state information to the MCU in real time so that the MCU obtains the first driving state information.

[0045] S102. When the main computing unit is controlled to stop running according to the first driving state information, second driving state information of the vehicle is obtained; wherein the second driving state information represents the current driving state of the vehicle obtained by the auxiliary computing unit in the vehicle.

[0046] Exemplarily, the main computing unit may send the first driving state information to the MCU, and the MCU determines whether to shut down the main computing unit according to the first driving state information. For example, it may be determined whether the first driving state information includes a preset first identification information, and the preset first identification information may indicate that the main computing unit currently needs to be shut down. If it includes, the main computing unit may be controlled to stop running; if it does not include, the main computing unit may be controlled to run normally.

[0047] In this embodiment, controlling the main computing unit to stop running according to the first driving state information includes: if it is determined that the first driving state information meets a preset shutdown condition, controlling the main computing unit to stop running.

[0048] Specifically, after receiving the first driving state information, the MCU can determine whether the first driving state information meets the preset shutdown condition. The main computing unit can also determine whether the first driving state information meets the preset shutdown condition, and then send the judgment result to the MCU, so that the MCU can understand whether the first driving state information meets the preset shutdown condition. The shutdown condition is set in advance. For example, the shutdown condition can be that the vehicle speed is 0, that is, it is determined whether the current vehicle speed is 0. If so, the shutdown condition is met, and the main computing unit can be controlled to stop running; if not, the shutdown condition is not met, and the main computing unit continues to operate normally.

[0049] If the first driving state information does not meet the preset shutdown condition, it means that the vehicle power supply cannot be cut off at present, and the vehicle continues to drive according to the current state. For example, if the user mistakenly sends a shutdown request during the driving of the vehicle, the vehicle can continue to drive normally.

[0050] If the first driving state information meets the preset shutdown condition, the MCU can send a shutdown command to the main computing unit. The main computing unit receives the shutdown command and stops running, that is, the main computing unit is shut down. After the main computing unit is shut down, the MCU will detect a shutdown completion feedback signal, and then instruct the auxiliary computing unit to obtain the second driving state information.

[0051] That is to say, after the main computing unit is turned off, the auxiliary computing unit can obtain the second driving state information of the vehicle again, and the second driving state information is the current driving state of the vehicle obtained by the auxiliary computing unit. The MCU can instruct the auxiliary computing unit to obtain the second driving state information, and after receiving the instruction from the MCU, the auxiliary computing unit obtains the current driving state information of the vehicle in real time as the second driving state information. The auxiliary computing unit can also send the second driving state information to the MCU in real time, so that the MCU obtains the second driving state information.

[0052] S103: When it is determined according to the second driving state information that the vehicle power supply needs to be turned off, the auxiliary computing unit is controlled to stop running and the vehicle power supply is turned off.

[0053] Exemplarily, the auxiliary computing unit may send the second driving state information to the MCU, and the MCU determines whether to control the auxiliary computing unit to shut down. For example, it may be determined whether the second driving state information includes the preset second identification information, and the preset second identification information may indicate that the auxiliary computing unit currently needs to be shut down. If it is included, the auxiliary computing unit may be controlled to stop running; if it is not included, the auxiliary computing unit is controlled to run normally.

[0054] In this embodiment, determining that the vehicle power supply needs to be shut down according to the second driving state information includes: if it is determined that the second driving state information meets a preset shutdown condition, controlling the auxiliary computing unit to stop running.

[0055] Specifically, it is determined whether the second driving status information meets the preset shutdown condition. The auxiliary computing unit can also determine whether the second driving status information meets the preset shutdown condition, and then send the determination result to the MCU, so that the MCU can understand whether the second driving status information meets the preset shutdown condition.

[0056] If the second driving state information does not meet the preset shutdown condition, it means that the vehicle power supply cannot be cut off at present, and the vehicle continues to drive according to the current state. For example, if the user mistakenly sends a shutdown request while the vehicle is driving, the vehicle can continue to drive normally. However, the main computing unit has been turned off at this time, so the auxiliary computing unit can take over the main computing unit and control the automatic driving of the vehicle. That is, if it is determined that the second driving state information does not meet the preset shutdown condition, the auxiliary computing unit is controlled to take over the automatic driving task of the vehicle.

[0057] If the second driving state information meets the preset shutdown condition, the MCU can send a shutdown command to the auxiliary computing unit. The auxiliary computing unit receives the shutdown command and stops running, that is, the auxiliary computing unit is shut down. After the auxiliary computing unit is shut down, the MCU will detect a shutdown completion feedback signal. If the MCU receives the shutdown completion feedback signal from the auxiliary computing unit and determines that the auxiliary computing unit is shut down, the main power supply of the entire on-board computing platform can be turned off, that is, the on-board power supply is cut off, thereby completing the safe shutdown of the entire autonomous driving system.

[0058] In this embodiment, it also includes: if the switch level signal of the vehicle power supply is converted from a low level signal to a high level signal, the vehicle power supply is turned on; a first power-on instruction is sent to the main computing unit, and a second power-on instruction is sent to the auxiliary computing unit; wherein the first power-on instruction is used to control the main computing unit to start running, and the second power-on instruction is used to control the auxiliary computing unit to start running.

[0059] Specifically, the vehicle power supply in the vehicle computing platform is controlled by the key power of the vehicle. The key power can be represented as a switch connected to the vehicle power supply. When the level on the key power cable, that is, the switch level, is a high-level signal, the vehicle computing platform is turned on and the vehicle power supply is connected; when the level on the key power cable is a low-level signal, the vehicle computing platform is turned off and the vehicle power supply is cut off. When a shutdown request is issued, the level on the key power cable changes from a high-level signal to a low-level signal. When some unexpected fault conditions occur, the key power cable may also change to a low-level signal, for example, when the key power cable is disconnected or loose, or when the key power is strongly interfered with.

[0060] After the vehicle-mounted computing platform is turned off, the switch level signal of the vehicle-mounted power supply can continue to be detected in real time. If the switch level signal of the vehicle-mounted power supply is converted from a low-level signal to a high-level signal, the vehicle-mounted power supply can be turned on again. For example, the preset low-level signal is 0V, and the preset high-level signal is 13V. When a 13V voltage appears on the key cable, the MCU of the vehicle-mounted computing platform detects this voltage, turns on the vehicle-mounted power supply, and the vehicle-mounted power supply will re-power all unit modules such as the main computing unit and the auxiliary computing unit. The MCU can first turn on the vehicle power supply, then send a first power-on instruction to the main computing unit, and send a second power-on instruction to the auxiliary computing unit. The first power-on instruction is used to control the main computing unit to start running, and the second power-on instruction is used to control the auxiliary computing unit to start running. The MCU does not specifically limit the order of sending the first power-on instruction and sending the second power-on instruction. That is, when shutting down, the main computing unit is turned off first, and then the auxiliary computing unit is turned off. When starting up, the main computing unit and the auxiliary computing unit can be turned on at the same time.

[0061] The beneficial effect of this setting is that the switch of the vehicle computing platform can be controlled according to the level signal on the key cable, and step-by-step judgment can be made when shutting down to avoid wrong shutdown. When starting up, the main computing unit and the auxiliary computing unit can be directly turned on to improve the startup efficiency and thus enhance the driving experience.

[0062] Figure 2 This is a schematic diagram of the structure of the vehicle computing platform. Figure 2 In the system, the MCU is connected to the main computing unit, the auxiliary computing unit, and the vehicle power supply, respectively, and can control the switches of the main computing unit, the auxiliary computing unit, and the vehicle power supply. The vehicle power supply is connected to the main computing unit and the auxiliary computing unit, respectively, and can supply power to the main computing unit and the auxiliary computing unit.

[0063] In the disclosed embodiment, when a shutdown request is received, it can be determined whether the main computing unit meets the shutdown conditions. If so, the main computing unit is turned off. Then it is determined whether the auxiliary computing unit meets the shutdown conditions. If so, the auxiliary computing unit is turned off, and finally the main power supply is turned off. Through multiple judgments, the problem of erroneous shutdown of the vehicle caused by erroneous triggering of the shutdown request is avoided, and the control stability and reliability of the vehicle power supply are improved. In addition, the asynchronous shutdown of the main computing unit and the auxiliary computing unit is realized. Even if the main computing unit is shut down by mistake, the auxiliary computing unit can continue to control the driving, thereby improving the driving safety.

[0064] Figure 3 A schematic flow chart of a method for controlling a vehicle power supply provided in an embodiment of the present disclosure.

[0065] like Figure 3 As shown, the method comprises the following steps:

[0066] S301. In response to a request to shut down the vehicle power supply, obtain first driving state information of the vehicle; wherein the first driving state information represents the current driving state of the vehicle obtained by a main computing unit in the vehicle.

[0067] For example, the switch level signal of the vehicle power supply is obtained in real time, and the switch level signal can represent the on / off request of the vehicle power supply. If the switch level signal of the vehicle power supply is converted from a high level signal to a low level signal, it is determined that a shutdown request for the vehicle power supply is received, and the current driving state information of the vehicle is obtained through the main computing unit, which is the first driving state information. The driving state information includes the automatic driving task currently executed by the vehicle and the current speed of the vehicle.

[0068] Specifically, the switch level signal of the vehicle power supply can represent the on / off request of the vehicle power supply. For example, when the switch level signal of the vehicle power supply is converted from a high level signal to a low level signal, it indicates that a shutdown request has been issued; when the switch level signal of the vehicle power supply is converted from a low level signal to a high level signal, it indicates that a power-on request has been issued. For example, the preset high level signal is a 13V voltage signal, and the preset low level signal is a 0V voltage signal. The MCU of the vehicle computing platform can detect the switch level signal of the vehicle power supply in real time.

[0069] If the MCU in the vehicle detects that the switch level signal is converted from a preset high level signal to a preset low level signal, it is determined that a shutdown request for the vehicle power supply is received. The MCU can control the main computing unit to obtain the current driving state information of the vehicle as the first driving state information. The driving state information may include the automatic driving task currently performed by the vehicle and the current speed of the vehicle. For example, when the user clicks the one-key shutdown button, a 0V voltage appears on the cable. After the MCU detects this voltage, it notifies the main computing unit to obtain the first driving state information.

[0070] In this embodiment, the low-level signal indicates shutdown. When shutting down, the first driving state information is first obtained through the main computing unit to realize gradual shutdown of the main computing unit and the auxiliary computing unit to avoid accidental shutdown affecting driving safety.

[0071] S302. If it is determined that the first driving state information meets the preset shutdown condition, the main computing unit is controlled to stop running, and the second driving state information of the vehicle is obtained; wherein the second driving state information represents the current driving state of the vehicle obtained by the auxiliary computing unit.

[0072] Exemplarily, whether the first driving state information satisfies the preset shutdown condition can be determined by the MCU, or by the main computing unit and then notified to the MCU. If the MCU determines that the first driving state information satisfies the preset shutdown condition, the main computing unit can be controlled to stop running. After the MCU determines that the main computing unit is shut down, the second driving state information of the vehicle can be obtained through the auxiliary computing unit.

[0073] In this embodiment, determining that the first driving status information satisfies the preset shutdown condition includes: if it is determined based on the first driving status information that the vehicle is not currently performing an automatic driving task, and the current speed of the vehicle is a preset speed value, then determining that the first driving status information satisfies the preset shutdown condition.

[0074] Specifically, the first driving state information may include the current speed of the vehicle, and may also include whether the vehicle is currently performing an autonomous driving task. A speed value is preset, for example, the speed value is 0m / s, that is, the vehicle is stationary. According to the first driving state information, it is determined whether the vehicle is currently performing an autonomous driving task, and whether the value of the current speed of the vehicle is a preset speed value. If the vehicle is not currently performing an autonomous driving task, and the value of the current speed of the vehicle is a preset speed value, it is determined that the first driving state information meets the preset shutdown condition; if the vehicle is currently performing an autonomous driving task, or the value of the current speed of the vehicle is not a preset speed value, it is determined that the first driving state information does not meet the preset shutdown condition.

[0075] That is to say, when the vehicle is performing an autonomous driving task, for example, the vehicle is parking automatically, the vehicle's onboard computing platform should not be shut down at this time, and a shutdown request may be issued by mistake, and the main computing unit should not be shut down. Alternatively, if the vehicle is currently driving at high speed, the main computing unit should not be shut down.

[0076] The beneficial effect of such a setting is that the cable may be subjected to abnormal interference, or the cable surface may be damaged and contact other metal bodies of the vehicle body, or a logic error may occur inside the MCU, causing the switch level signal to become a low level signal or a shutdown request to be issued. By judging whether the first driving state information meets the shutdown condition, the main computing unit can be prevented from shutting down incorrectly, ensuring the normal driving of the vehicle and improving driving safety.

[0077] In this embodiment, controlling the main computing unit to stop running includes: obtaining the current switch level signal of the vehicle power supply, and controlling the main computing unit to stop running according to the current switch level signal of the vehicle power supply. For example, a voltage value may be preset, and if the voltage value represented by the current switch level signal is the preset voltage value, the main computing unit may be controlled to stop running; otherwise, the main computing unit may not be controlled to stop running.

[0078] In this embodiment, the main computing unit is controlled to stop running according to the current switch level signal of the vehicle power supply, including: if the current switch level signal is a low level signal, a first shutdown command is sent to the main computing unit; wherein the first shutdown command is used to control the main computing unit to stop running.

[0079] Specifically, after determining that the first driving status information meets the preset shutdown conditions, the MCU can issue a shutdown command to the main computing unit to control the main computing unit to stop running. The shutdown command issued by the MCU to the main computing unit is the first shutdown command. Before issuing the first shutdown command, the MCU can confirm again whether the current switch level signal is still the preset low-level signal. If so, it means that it is indeed necessary to shut down, and the first shutdown command is issued to the main computing unit; if not, it means that an accidental touch or failure may have occurred just now, causing the switch level signal to temporarily become a low-level signal, and there is no need to shut down, that is, there is no need to issue the first shutdown command to the main computing unit, and the on-board computing platform continues to operate normally.

[0080] After receiving the first shutdown command, the main computing unit shuts down the main computing unit and feeds back a shutdown completion message to the MCU. The MCU receives the feedback message from the main computing unit, determines that the main computing unit has completed the shutdown, and obtains the second driving state information through the auxiliary computing unit.

[0081] The beneficial effect of such a setting is that before issuing the first shutdown command, the switch level signal is confirmed again, thereby improving the control accuracy of the vehicle power supply, avoiding accidental shutdown, and improving driving safety.

[0082] In this embodiment, if the current switch level signal is a low level signal, a first shutdown command is sent to the main computing unit, including: if the current switch level signal is a low level signal, obtaining the vehicle's new first driving status information again; if it is determined that the new first driving status information meets the preset shutdown conditions, a first shutdown command is sent to the main computing unit.

[0083] Specifically, after determining that the current switch level signal is still a low level signal, the MCU can obtain the current first driving state information again through the main computing unit, that is, obtain new first driving state information. For example, the MCU can send an information acquisition instruction to the main computing unit, and the main computing unit collects the new first driving state information.

[0084] After obtaining the new first driving state information, the main computing unit can send the new first driving state information to the MCU, and the MCU can judge again whether the new first driving state information meets the preset shutdown condition. The main computing unit can also judge again whether the new first driving state information meets the preset shutdown condition, and send the judgment result to the MCU. For example, it can be judged again whether the vehicle is not currently performing an automatic driving task, and whether the current speed of the vehicle is a preset speed threshold. If so, it is determined that the new first driving state information meets the preset shutdown condition. After determining that the new first driving state information meets the preset shutdown condition, the MCU can send the first shutdown instruction to the main computing unit.

[0085] The beneficial effect of such a setting is that the first driving state information is obtained again and the shutdown condition is judged, ensuring that the vehicle power supply can be cut off at present to avoid affecting the driving of the vehicle.

[0086] In this embodiment, after determining that the current switch level signal is still a low level signal, the MCU can directly send a first shutdown instruction to the main computing unit. The main computing unit receives the first shutdown instruction, obtains new first driving state information, and determines whether the new first driving state information meets the preset shutdown condition. If so, the main computing unit itself is directly shut down and the shutdown result is fed back to the MCU; if not, the shutdown is not performed.

[0087] S303: If it is determined that the second driving state information meets the preset shutdown condition, the auxiliary computing unit is controlled to stop running and the vehicle power supply is turned off.

[0088] Exemplarily, this step may refer to the above-mentioned step S103 and will not be described in detail.

[0089] In the disclosed embodiment, when a shutdown request is received, it can be determined whether the main computing unit meets the shutdown conditions. If so, the main computing unit is turned off. Then it is determined whether the auxiliary computing unit meets the shutdown conditions. If so, the auxiliary computing unit is turned off, and finally the main power supply is turned off. Through multiple judgments, the problem of erroneous shutdown of the vehicle caused by erroneous triggering of the shutdown request is avoided. The asynchronous shutdown of the main computing unit and the auxiliary computing unit is realized. Even if the main computing unit is shut down by mistake, the auxiliary computing unit can continue to control the driving, thereby improving the safety of driving.

[0090] Figure 4 A schematic flow chart of a method for controlling a vehicle power supply provided in an embodiment of the present disclosure.

[0091] In this embodiment, obtaining the second driving state information of the vehicle includes: receiving first feedback information sent by the main computing unit; wherein the first feedback information represents the completion status of the shutdown of the main computing unit; if the first feedback information represents that the main computing unit has completed the shutdown, then obtaining the second driving state information of the vehicle.

[0092] like Figure 4 As shown, the method comprises the following steps:

[0093] S401. In response to a request to shut down the vehicle power supply, obtain first driving state information of the vehicle; wherein the first driving state information represents the current driving state of the vehicle obtained by a main computing unit in the vehicle.

[0094] Exemplarily, this step may refer to the above-mentioned step S101 and will not be described in detail.

[0095] S402: If it is determined that the first driving state information meets a preset shutdown condition, the main computing unit is controlled to stop running.

[0096] Exemplarily, this step may refer to the above-mentioned step S102 and will not be described in detail.

[0097] S403, receiving first feedback information sent by the main computing unit; wherein the first feedback information represents the completion status of the shutdown of the main computing unit.

[0098] Exemplarily, after executing the first shutdown instruction, the main computing unit may generate a shutdown completion feedback information as the first feedback information. That is, the first feedback information may characterize the completion of the first shutdown instruction by the main computing unit, for example, it may indicate that the shutdown is completed or not completed. The main computing unit may send the first feedback information to the MCU.

[0099] S404: If the first feedback information indicates that the main computing unit has completed shutdown, obtaining second driving state information of the vehicle.

[0100] Exemplarily, after receiving the first feedback information, the MCU determines whether the main computing unit has completed shutdown according to the first feedback information. If it is determined that the first feedback information indicates that the main computing unit has completed shutdown, the MCU can obtain the second driving state information of the vehicle through the auxiliary computing unit. For example, the MCU can send an information acquisition instruction to the auxiliary computing unit, and the auxiliary computing unit obtains the second driving state information. The auxiliary computing unit can also send the second driving state information to the MCU.

[0101] In this embodiment, the main computing unit is first shut down, and then the second driving status information is obtained to shut down the auxiliary computing unit, thereby gradually shutting down the main computing unit and the auxiliary computing unit. When the main computing unit is abnormally shut down, the auxiliary computing unit can take over the vehicle's automatic driving function to achieve safe driving.

[0102] S405: If it is determined that the second driving state information meets the preset shutdown condition, the auxiliary computing unit is controlled to stop running and the vehicle power supply is turned off.

[0103] Exemplarily, whether the second driving state information satisfies the preset shutdown condition can be determined by the MCU, or the auxiliary computing unit can determine and then inform the MCU. If the MCU determines that the second driving state information satisfies the preset shutdown condition, the auxiliary computing unit can be controlled to stop running. After the MCU determines that the auxiliary computing unit is shut down, the vehicle power supply can be turned off.

[0104] In this embodiment, determining that the second driving state information meets the preset shutdown condition includes: if it is determined based on the second driving state information that the vehicle is not currently performing an automatic driving task, and the current speed of the vehicle is a preset speed value, then determining that the second driving state information meets the preset shutdown condition.

[0105] Specifically, the second driving state information may include the current speed of the vehicle, and may also include whether the vehicle is currently performing an autonomous driving task. A speed value is preset, for example, the speed value is 0m / s, that is, the vehicle is stationary. According to the second driving state information, it is determined whether the vehicle is currently performing an autonomous driving task, and whether the value of the current speed of the vehicle is a preset speed value. If the vehicle is not currently performing an autonomous driving task, and the value of the current speed of the vehicle is a preset speed value, it is determined that the second driving state information meets the preset shutdown condition; if the vehicle is currently performing an autonomous driving task, or the value of the current speed of the vehicle is not a preset speed value, it is determined that the second driving state information does not meet the preset shutdown condition.

[0106] That is to say, when the vehicle is performing an autonomous driving task, for example, the vehicle is parking automatically, the vehicle's onboard computing platform should not be shut down at this time, and a shutdown request may have been issued by mistake, and the auxiliary computing unit should not be shut down. Alternatively, if the vehicle is currently driving at high speed, the auxiliary computing unit should not be shut down either.

[0107] The beneficial effect of such a setting is that the cable may be subjected to abnormal interference, or the cable surface may be damaged and contact other metal bodies of the vehicle body, or a logic error may occur inside the MCU, causing the switch voltage signal to become a low-level signal or a shutdown request to be issued. By judging whether the second driving state information meets the shutdown condition, the auxiliary computing unit can be prevented from shutting down incorrectly, ensuring the normal driving of the vehicle and improving driving safety.

[0108] In this embodiment, controlling the auxiliary computing unit to stop running includes: obtaining a current switch level signal of the vehicle power supply, and controlling the auxiliary computing unit to stop running according to the current switch level signal of the vehicle power supply. For example, a voltage value may be preset, and if the voltage value represented by the current switch level signal is the preset voltage value, the auxiliary computing unit may be controlled to stop running; otherwise, the auxiliary computing unit may not be controlled to stop running.

[0109] In this embodiment, the auxiliary computing unit is controlled to stop running according to the current switch level signal of the vehicle power supply, including: if the current switch level signal is a low level signal, a second shutdown instruction is sent to the auxiliary computing unit; wherein the second shutdown instruction is used to control the auxiliary computing unit to stop running.

[0110] Specifically, after determining that the second driving state information meets the preset shutdown conditions, the MCU can issue a shutdown command to the auxiliary computing unit to control the auxiliary computing unit to stop running. The shutdown command issued by the MCU to the auxiliary computing unit is the second shutdown command. Before issuing the second shutdown command, the MCU can confirm again whether the current switch level signal is still the preset low-level signal. If so, it means that it is indeed necessary to shut down, and issue the second shutdown command to the auxiliary computing unit; if not, it means that an accidental touch or failure may have occurred just now, causing the switch level signal to temporarily become a low-level signal, and there is no need to shut down, that is, there is no need to issue a second shutdown command to the auxiliary computing unit, and the on-board computing platform continues to operate normally.

[0111] After receiving the second shutdown command, the auxiliary computing unit shuts down the auxiliary computing unit and feeds back a shutdown completion message to the MCU. The MCU receives the feedback message from the auxiliary computing unit, determines that the auxiliary computing unit has completed the shutdown, and can continue to shut down the vehicle power supply.

[0112] The beneficial effect of such a setting is that before issuing the second shutdown command, the switch level signal is confirmed again, thereby improving the control accuracy of the vehicle power supply, avoiding accidental shutdown, and improving driving safety.

[0113] In this embodiment, if the current switch level signal is a low level signal, a second shutdown command is sent to the auxiliary computing unit, including: if the current switch level signal is a low level signal, the new second driving status information of the vehicle is obtained again; if it is determined that the new second driving status information meets the preset shutdown conditions, a second shutdown command is sent to the auxiliary computing unit.

[0114] Specifically, after determining that the current switch level signal is still a low level signal, the MCU can obtain the current second driving state information again through the auxiliary computing unit, that is, obtain new second driving state information. For example, the MCU can send an information acquisition instruction to the auxiliary computing unit, and the auxiliary computing unit collects the new second driving state information.

[0115] After obtaining the new second driving state information, the auxiliary computing unit can send the new second driving state information to the MCU, and the MCU can judge again whether the new second driving state information meets the preset shutdown condition. The auxiliary computing unit can also judge again whether the new second driving state information meets the preset shutdown condition, and send the judgment result to the MCU. For example, it can be judged again whether the vehicle is not currently performing the automatic driving task, and whether the current speed of the vehicle is the preset speed value. If so, it is determined that the new second driving state information meets the preset shutdown condition. After determining that the new second driving state information meets the preset shutdown condition, the MCU can send a second shutdown instruction to the auxiliary computing unit.

[0116] The beneficial effect of such a setting is that the second driving state information is obtained again and the shutdown condition is judged, ensuring that the vehicle power supply can be cut off at present to avoid affecting the driving of the vehicle.

[0117] In this embodiment, after determining that the current switch level signal is still a low level signal, the MCU can directly send a second shutdown instruction to the auxiliary computing unit. The auxiliary computing unit receives the second shutdown instruction, obtains new second driving state information, and determines whether the new second driving state information meets the preset shutdown condition. If so, the auxiliary computing unit itself is directly shut down and the shutdown result is fed back to the MCU; if not, the shutdown is not performed.

[0118] In this embodiment, shutting down the vehicle power supply includes: receiving second feedback information sent by the auxiliary computing unit; wherein the second feedback information represents the completion status of the shutdown of the auxiliary computing unit; if the second feedback information represents that the auxiliary computing unit has completed the shutdown, shutting down the vehicle power supply.

[0119] Specifically, after executing the second shutdown instruction, the auxiliary computing unit may generate a shutdown completion feedback information as the second feedback information. That is, the second feedback information may characterize the completion of the second shutdown instruction by the auxiliary computing unit, for example, it may indicate that the shutdown is completed or not completed. The auxiliary computing unit may send the second feedback information to the MCU.

[0120] After receiving the second feedback information, the MCU determines whether the auxiliary computing unit has completed shutdown according to the second feedback information. If it is determined that the second feedback information indicates that the auxiliary computing unit has completed shutdown, the MCU can turn off the vehicle power supply and stop supplying power to the main computing unit and the auxiliary computing unit.

[0121] The beneficial effect of this setting is that the main computing unit is turned off first, then the auxiliary computing unit, and finally the vehicle power supply is cut off. This can avoid abnormal shutdown of the autonomous driving system due to line failure or MCU control logic errors, thereby improving the safety and reliability of autonomous driving vehicles.

[0122] In the disclosed embodiment, when a shutdown request is received, it can be determined whether the main computing unit meets the shutdown conditions. If so, the main computing unit is turned off. Then it is determined whether the auxiliary computing unit meets the shutdown conditions. If so, the auxiliary computing unit is turned off, and finally the main power supply is turned off. Through multiple judgments, the problem of erroneous shutdown of the vehicle caused by erroneous triggering of the shutdown request is avoided. The asynchronous shutdown of the main computing unit and the auxiliary computing unit is realized. Even if the main computing unit is shut down by mistake, the auxiliary computing unit can continue to control the driving, thereby improving the safety of driving.
