[0025] The method embodiment can be executed in an electronic device or similar computing device in a vehicle including a memory and a processor. For example, the method can be executed in an electronic device in a vehicle.

[0029] Figure 2 is a flow chart of a first embodiment of a vehicle control method according to the present application, such as Figure 2 As shown, the process includes the following steps:

[0030] Step S21, when it is determined that the vehicle power is in the off mode and the vehicle meets the vehicle network sleep condition, detecting whether the application layer has completed the release of the CAN network;

[0031] In this step, the vehicle network sleep condition is that there is no wake-up signal and the preset time is 3 minutes. That is, when the vehicle power is turned off and there is no wake-up signal, the vehicle enters the network sleep state after three minutes.

[0032] Step S22, when the application layer has not completed releasing the CAN network, starting a timer to count the holding time of the CAN network and obtaining holding time information of the CAN network;

[0033] Step S23, when the holding time information meets the preset condition, a first control strategy is generated, and the first control strategy is used to control the controller to forcibly release the CAN network. In this step, the preset condition is set to that the holding time of the CAN network reaches 5 minutes.

[0034] By applying the technical solution of this embodiment, when it is determined that the vehicle power is in the off mode and the vehicle meets the vehicle network sleep conditions, by detecting whether the application layer has completed the release of the CAN network, if the application layer has not completed the release of the CAN, it is proved that there is a communication abnormality in the CAN network. At this time, the timer is started to count the retention time of the CAN network, and the retention time information of the CAN network is obtained. When the retention time information meets the preset conditions, a first control strategy is generated. The first control strategy is used to control the controller to force the release of the CAN network. In this way, when the CAN network communication is abnormally maintained due to a controller software failure and the CAN network cannot enter sleep mode, the timer timeout can be used to count, and after the timeout, the controller itself is controlled to force the release of the CAN network, so that the controller forms a network abnormality protection mechanism for sleep control, thereby achieving the purpose of eliminating the abnormal retention failure of the CAN network, ensuring that the CAN network of the whole vehicle enters the sleep state normally, and ensuring the normal operation of the low-voltage electric energy management system of the whole vehicle.

[0035] like Figure 4 The flowchart of the second embodiment of the vehicle control method according to the present application is shown. When the retention time information meets the preset conditions, a first control strategy is generated. The first control strategy is used to control the controller to forcibly release the CAN network. The method further includes the following steps:

[0036] Step S31, receiving a wake-up signal, wherein the wake-up signal is sent by the faulty device and is used to wake up the CAN network;

[0037] In the technical solution provided in the above step S31 of the present invention, a wake-up signal is received, wherein the wake-up signal is sent by the faulty device, and the wake-up signal is used to wake up the CAN network. For example, the wake-up signal can be a signal of no output of the hazard warning light sent by the body controller (active controller), or it can be an unconditional execution signal sent by the seat controller (passive controller). This is only an example for illustration without specific limitation.

[0038] Step S32, determining whether the wake-up signal is sent by the same faulty device;

[0039] In the technical solution provided in the above step S32 of the present invention, it is determined whether the wake-up signal is sent by the same faulty device, wherein the faulty device may be a body controller, a seat controller or other controller with an abnormality, or a module with a fault in the application layer of the controller, such as a thermal management module. This is only an example and is not specifically limited.

[0040] Step S33: if yes, generate a second control strategy, the second control strategy is used to control the CAN network to enter the sleep mode.

[0041] In this embodiment, when the same faulty device sends a wake-up signal requesting to wake up the CAN network, the CAN network is controlled to enter sleep mode, and the same faulty device is not allowed to wake up the CAN network again, thereby further achieving the technical effect of eliminating abnormal maintenance faults of the CAN network.

[0042] In such Figure 4 In the illustrated embodiment, the method further includes: in the case of KL15OFF (vehicle power is off), if after the power is off, there is no wake-up source requesting to wake up the CAN network and the timer reaches three minutes, the entire vehicle network enters sleep mode. At this time, it is determined whether the ECU application layer has released the CAN network. If not, it proves that the controller has software bugs that cause initialization failure, state machine stagnation, timing errors, software and hardware compatibility, and other problems, which lead to abnormal CAN network communication. At this time, the controller starts a five-minute timer to time the duration of the abnormal CAN network communication. If the duration of the abnormal CAN network communication reaches five minutes, the controller is controlled to release the network, stop sending network management messages, and wait for the network to sleep. After the controller releases the network, while waiting for the network to sleep, if a wake-up signal (corresponding to Figure 4 If the trigger wake-up condition x in the above example is set, it is determined whether the wake-up signal is sent by the same faulty device (corresponding to Figure 4 Is it the cause of the last fault? If yes, the control bus goes into sleep mode without network management messages, and the wake-up signal sent by the same faulty device is not allowed to request the CAN network again during the sleep-wake-up cycle of the CAN network. In addition, the passive controller is not allowed to actively wake up the CAN network after the bus goes into sleep mode, thereby eliminating the abnormal maintenance fault of the CAN network and solving the problem of abnormal maintenance of the vehicle network communication due to controller software failure.

[0043] Optionally, the method further comprises:

[0044] Step S41, during the timing of the timer, the operating modes of the controller and the vehicle power supply are obtained in real time;

[0045] In this step, the working modes of the vehicle power supply include shutdown mode (OFF mode), power-on mode (ACC mode), start ignition mode (CRANK mode) and operation mode (ON mode). The working modes of the controller include power-on mode, power-off sleep mode, brake mode, charging mode, fault mode and driving mode. Among them, the power-off sleep mode includes ready sleep mode, ready bus sleep mode and sleep mode.

[0046] Step S42, when the working mode meets the preset mode, a third control strategy is generated, and the third control strategy is used to reset the timing of the timer and stop the timer from timing. The preset mode includes: the working mode of the controller is the ready sleep mode, the ready bus sleep mode, and any working mode in the sleep mode, and the working mode of the vehicle power supply is any working mode in the start ignition mode (CRANK mode) and the operation mode (ON mode).

[0047] In this embodiment, during the timing of the timer, if the controller enters any one of the working modes including the ready sleep mode, the ready bus sleep mode and the sleep mode, it proves that the CAN network can enter sleep mode normally, and if the vehicle power jumps to the start ignition mode (CRANK mode) or the running mode (ON mode), it means that the sleep condition of the entire vehicle network is no longer met at this time. At this time, the timing of the timer is cleared and the timer is stopped. Therefore, when the CAN network can sleep normally, the controller is no longer controlled to force the release of the CAN network to ensure the normal sleep of the CAN network, and when the vehicle does not meet the sleep condition of the entire vehicle network, the controller is no longer controlled to force the release of the CAN network to ensure the normal operation of the vehicle.

[0048] Optionally, the method further includes: when it is determined that the wake-up signal is sent by different faulty devices, re-determining whether to generate the first control strategy to execute the forced release of the CAN network. Specifically, when the wake-up signal is sent by different faulty devices, re-execute steps S31-S33 in the above embodiment to determine whether to generate the first control strategy to execute the forced release of the CAN network. When the vehicle network communication is abnormally maintained due to different software failures of the controller, the controller re-executes the forced release of the CAN network, thereby further achieving the purpose of eliminating the abnormal maintenance failure of the CAN network and ensuring that the CAN network of the whole vehicle enters the sleep state normally.

[0049] Optionally, when the application layer has not completed releasing the CAN network, the method further includes: detecting whether there is a faulty device in the vehicle, and if so, repairing the faulty device. In this embodiment, if it is detected that there is a faulty device in the vehicle, the faulty device is controlled to perform self-repair, wherein the faulty device can perform self-repair through networking or by relying on its own abnormal protection mechanism. By repairing the faulty device, the controller is ensured to enter sleep normally, thereby eliminating the abnormal maintenance fault of the CAN network.

[0050] Optionally, the method further includes: obtaining the repair time required to repair the faulty device, determining whether the repair time is greater than the retention time, and if so, extending the timing time of the timer to the repair time required to repair the faulty device. Specifically, the repair time is the time from when the faulty device starts to repair its own existing bug to when the bug is completely eliminated. During the repair period, if the faulty device uses networking for self-repair, then when the repair time is greater than the retention time of the CAN network abnormality, the timing time of the timer is extended to the repair time required to repair the faulty device, thereby ensuring that the faulty device continues to use the CAN network for self-repair until the faulty device completely eliminates the existing bug. At this time, the CAN network is controlled to enter a dormant state, thereby achieving the purpose of repairing the faulty device and ensuring that the CAN network enters dormancy normally.

[0051] like Figure 5 The flowchart of the third embodiment of the vehicle control method according to the present application is shown. In the case where the vehicle does not have a wake-up source, if it is determined that the vehicle power is in the off mode ( Figure 5 In the case of KL15 being OFF), and the vehicle meets the vehicle network sleep conditions, by detecting whether the application layer has completed the release of the CAN network (corresponding to Figure 5 In the case that the ECU application layer has released the network), if the application layer has not completed the release of the CAN network, the timer is started to count the holding time of the CAN network, and the holding time information of the CAN network is obtained. If the time information meets the preset conditions, the controller forces the network to be released, stops sending network management messages, and prohibits waking up the CAN network. Among them, the timer is a five-minute timer, and the wake-up source 30 is a device or signal source for waking up the vehicle controller.

[0052] According to another specific embodiment of the present application, a vehicle control device is provided, such as Figure 3As shown, the control device includes: a detection module 42, a timing module 44 and a control module 46. The detection module 42 is used to detect whether the application layer has completed the release of the CAN network when it is determined that the vehicle power is in the off mode and the vehicle meets the vehicle network sleep condition. The timing module 44 is used to start the timer to count the retention time of the CAN network and obtain the retention time information of the CAN network when the application layer has not completed the release of the CAN network; the control module 46 is used to generate a first control strategy when the retention time information meets the preset conditions, and the first control strategy is used to control the controller to force the release of the CAN network.

[0053] In this embodiment, when it is determined that the vehicle power is in the off mode and the vehicle meets the vehicle network sleep conditions, by detecting whether the application layer has completed the release of the CAN network, if the application layer has not completed the release of the CAN, it is proved that the CAN network has abnormal communication retention phenomenon. At this time, the timer is started to count the retention time of the CAN network, and the retention time information of the CAN network is obtained. When the retention time information meets the preset conditions, the first control strategy is generated. The first control strategy is used to control the controller to force the release of the CAN network. In this way, when the CAN network communication is abnormally retained due to a controller software failure and the CAN network cannot enter sleep mode, the timer timeout can be used to count, and after the timeout, the controller itself is controlled to force the release of the CAN network, so that the controller forms a network abnormality protection mechanism for sleep control, thereby achieving the technical effect of eliminating the abnormal retention failure of the CAN network, ensuring that the CAN network of the whole vehicle enters the sleep state normally, and ensuring the normal operation of the low-voltage electric energy management system of the whole vehicle.

[0054] The control method of the vehicle of the present application mainly relies on the AUTOSAR network management protocol, through the forced sleep mechanism, the controller is used as the main logic control unit to form a complete network abnormality protection mechanism for sleep control, and a five-minute timer is used to time the five-minute timeout timing strategy, and combined with the network retention reason (fault reason), the controller is forced to release the network, effectively solving the abnormal retention problem of the CAN network caused by the software failure of the controller, ensuring that the CAN network of the whole vehicle enters the sleep state normally, and ensuring the normal operation of the low-voltage electric energy management system of the whole vehicle. The control method of the vehicle of the present application is carried on any controller, such as the body domain controller and the gateway. As an alternative embodiment, the controller bottom layer timeout timing mechanism can also be used and combined with the application layer to judge the reason for the CAN network to maintain, so as to realize the controller's own forced release network strategy. As another alternative embodiment, the central controller can also be used to centrally control and judge the CAN network retention time, so as to achieve the timeout and send a forced sleep instruction to control each network segment controller to enter sleep. It should be noted that the release network of the present application refers to disconnecting from the network.

[0056] According to another specific embodiment of the present application, an electronic device is provided, including a memory and a processor, wherein a computer program is stored in the memory, and the processor is configured to run the computer program to execute the steps of the vehicle control method in the above embodiment.

[0057] According to another specific embodiment of the present application, a vehicle is provided, the vehicle includes the electronic device in the above embodiment, and the vehicle is controlled by the control method of the vehicle in the above embodiment. In this embodiment, each controller of the vehicle starts the timeout timing after the vehicle power mode is OFF, and adopts the strategy of controlling the application layer to release the CAN network after the timeout, and each controller undertakes the demand to form a network abnormality protection mechanism for dormant control, so that the overall control process of the whole vehicle from the occurrence of the fault to the elimination of the fault is realized through the self-repair of each controller, and the market problem of the whole vehicle power shortage caused by the abnormal maintenance of the CAN network is eliminated, ensuring that the CAN network of the whole vehicle enters the dormant state normally, and ensuring the normal operation of the low-voltage electric energy management system of the whole vehicle.
