The memory 15 may include a program storage area and a data storage area. The program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playback function, an image playback function, etc.), and instructions for implementing the following method embodiments.

[0025] See also Figure 2 , Figure 2 A flow chart of a vehicle control method according to one embodiment of the present application is shown, which is used for a vehicle. The method includes: S110 : In response to a failure of a zone controller of a vehicle, locking a power distribution state of a power distribution channel of the zone controller.

[0026] In this application, the vehicle can be an electric vehicle or a fuel vehicle, or it can be a car, SUV, bus, truck, etc.

[0027] A vehicle's zone controller is a core component in modern automotive electronics architecture. It is a control module that integrates the functions of multiple electronic control units (ECUs) and is typically designed for specific functional areas, such as powertrain, body, and infotainment. The zone controller processes data from various sensors and implements corresponding control through actuators.

[0028] Typically, a vehicle's zone controller integrates multiple control modules, including window control, seat control, air conditioning control, wiper control, and intelligent power distribution control. The vehicle's power supply distributes power to each module in the zone controller, ensuring its normal operation.

[0029] The power distribution channels of a regional controller are used to distribute power to each module within the regional controller. The vehicle's power is distributed to each module through these channels. Each module in the regional controller can have its own corresponding power distribution channel, allowing power to be distributed to each module through its corresponding distribution channel.

[0030] The zone controller may exhibit unexpected behaviors such as accidental freezing or software errors. When the zone controller exhibits unexpected behaviors such as accidental freezing or software errors, it is determined that the zone controller of the vehicle has failed.

[0031] Afterwards, the power distribution status of the power distribution channel of the area controller can be locked so that the power distribution channel of the area controller is in a locked state and the status of the power distribution channel of the area controller no longer changes. At this time, even if a signal sent by the vehicle to change the status of the power distribution channel of the area controller is received, the power distribution status of the power distribution channel of the area controller will not be changed.

[0032] The power distribution status of the zone controller's power distribution channel refers to the on / off status of the zone controller's power distribution channel. For example, if the zone controller includes three control modules: window control, seat control, and air conditioning control, the power distribution status of the zone controller's power distribution channel may include the on / off status of the window control module's power distribution channel, the seat control module's power distribution channel, and the air conditioning control module's power distribution channel: the window control module's power distribution channel is on, the seat control module's power distribution channel is on, and the air conditioning control module's power distribution channel is off.

[0033] In some embodiments, a vehicle may include a power management chip. The vehicle's power management chip is a core component for controlling, monitoring, and regulating the vehicle's power transmission and distribution, primarily enabling efficient power management and safe system operation. The power management chip may be a chip structure within a regional controller. The power management chip includes a built-in watchdog module. In this case, prior to S110, the method may include: the regional controller periodically sending a watchdog signal to the watchdog module of the vehicle's power management chip; the power management chip generating a reset signal in response to the watchdog module receiving a specified time interval since the last time it received the watchdog signal; the reset signal indicating a regional controller failure. Therefore, if the power management chip detects the reset signal, it indicates a regional controller failure, and step S110 is continued. The specified time interval is not less than the periodic duration of the periodic sending of the watchdog signal. For example, the periodic sending of the watchdog signal is 500ms, and the specified time interval is 800ms.

[0034] In other words, the regional controller can have a built-in program or script that matches the watchdog module. Through this program or script, the MCU (microcontroller unit) inside the regional controller periodically sends a dog-feeding signal to the watchdog module of the vehicle's power management chip (this actually refers to the power management chip in the vehicle's regional controller). The watchdog module in the power management chip can receive the periodic dog-feeding signal sent by the regional controller, so that the watchdog module can receive the periodic dog-feeding signal, and the power management chip does not need to generate a reset signal. At this time, it indicates that the regional controller has not encountered any software errors, etc., and the regional controller has not failed.

[0035] Accordingly, the watchdog module in the power management chip responds to the specified time duration since the last time it received the dog-feeding signal, which means that the zone controller has failed to periodically send the dog-feeding signal according to a fixed cycle since the last time it sent the dog-feeding signal. The watchdog module cannot receive the periodic dog-feeding signal, and the MCU in the zone controller may have encountered a software error, etc. The watchdog module determines that the timing period has timed out, and the power management chip generates a reset signal. At this time, it means that the zone controller has encountered a software error, etc., and the zone controller has failed. That is, in this application, the power management chip determines whether to generate a reset signal based on whether the watchdog module has timed out, and uses the reset signal to indicate that the MCU in the zone controller has failed.

[0036] The watchdog module of the power management chip refers to a module that can receive a dog feeding signal and determine whether the timing cycle has timed out based on whether a periodic dog feeding signal is received. Of course, the watchdog module can also implement other functions, such as timing function, current monitoring, etc.

[0037] The watchdog feeding signal may be a signal indicating that the MCU of the zone controller is operating normally. It may be a signal in any form, which may include data indicating that the MCU of the zone controller is operating normally, or other information such as a timestamp, an identifier of the watchdog module, and a vehicle identifier.

[0038] After determining that a regional controller's MCU has failed, the regional controller's power management chip can lock the power distribution status of the regional controller's power distribution channels. Specifically, this process includes: in response to the regional controller failure, the power management chip generates a self-locking signal based on a reset signal; the power management chip executes a self-locking operation based on the self-locking signal to lock the power distribution status of the power distribution channels.

[0039] That is, the power management chip generates a self-locking signal in response to the received reset signal, and then the power management chip performs a self-locking operation based on the self-locking signal to lock the power distribution state of the power distribution channel of the zone controller.

[0040] S120: Initialize the regional controller.

[0041] After locking the power distribution status of the power distribution channel of the zone controller, the zone controller can be initialized to eliminate the fault of the zone controller through the initialization operation.

[0042] Optionally, as mentioned above, the vehicle also includes a power management chip, the power management chip also includes a watchdog module, and the watchdog module also generates a reset signal. Thus, the zone controller can be initialized based on the reset signal, so that the zone controller can be initialized directly through the reset signal. No additional control behavior is required to control the initialization of the zone controller, thereby improving the initialization efficiency of the zone controller.

[0043] S130 : In response to completion of initialization of the regional controller, restore power distribution to the power distribution channel based on output status information of the target power distribution channel.

[0044] The target distribution channel output status information refers to the distribution channel's distribution status information before the regional controller fails. The distribution channel's distribution status information of the regional controller refers to information indicating the distribution channel's distribution status, which may be a numerical or alphanumeric identifier.

[0045] That is to say, before the regional controller fails, the power distribution status information of the regional controller's power distribution channel is recorded as the target power distribution channel output status information. Then, after the regional controller is initialized, the power distribution of the regional controller's power distribution channel is restored through the target power distribution channel output status information, so that the power distribution status of the regional controller's power distribution channel is restored to the distribution status indicated by the target distribution channel output status information.

[0046] For example, when the regional controller includes four control modules: window control, seat control, air conditioning control and wiper control, the target power distribution channel output status information is: the power distribution channel of the window control module is on, the power distribution channel of the seat control module is on, the power distribution channel of the air conditioning control module is closed, and the power distribution channel of the wiper control module is closed. After the initialization of the regional controller is completed, the power distribution channel of the regional controller is restored through the target power distribution channel output status information. The power distribution status of the power distribution channel of the restored regional controller is: the power distribution channel of the window control module is on, the power distribution channel of the seat control module is on, the power distribution channel of the air conditioning control module is closed, and the power distribution channel of the wiper control module is closed.

[0047] S140: Unlock the power distribution status of the power distribution channel.

[0048] After the zone controller is initialized, the fault of the zone controller can be eliminated, and then the power distribution status of the zone controller's power distribution channel can be restored (power distribution restoration is achieved based on the output status information of the target power distribution channel). After the power distribution restoration is completed, the power distribution status of the zone controller's power distribution channel can be unlocked to facilitate the vehicle to change the power distribution status of the zone controller's power distribution channel based on signals generated by specific driving behavior or driving mode.

[0049] In this embodiment, when a regional controller fails, the power distribution status of the power distribution channels of the regional controller is first locked, and then the regional controller is initialized. This ensures that the power distribution status of the power distribution channels of the regional controller does not change during the regional controller initialization process, thereby preventing the regional controller from losing power during the regional controller initialization process, thereby reducing safety hazards during vehicle driving and improving vehicle driving safety.

[0050] Secondly, a hardware watchdog module is introduced. This module monitors the zone controller for abnormalities and responds immediately to any abnormalities, generating a reset signal. This reset signal allows the power distribution status of the zone controller's power distribution channels to be quickly and directly locked, and the zone controller is initialized, improving vehicle control efficiency. Furthermore, the watchdog module is low-cost and easy to implement.

[0051] In some embodiments, as Figure 3 As shown, S130 includes: S131 . In response to the completion of the initialization of the regional controller, initialize the power management chip.

[0052] As mentioned above, the vehicle also includes a power management chip, and the power management chip also includes a watchdog module. At this time, after initializing the zone controller, the power management chip can also be initialized.

[0053] S132 : In response to the completion of initialization of the power management chip, restore power distribution to the power distribution channel based on the output status information of the target power distribution channel.

[0054] That is to say, after completing the initialization of the regional controller, the power management chip also needs to be initialized. Only after the power management chip initialization is completed, it is determined that the regional controller initialization is completed and the regional controller can operate normally. At this time, based on the output status information of the target distribution channel, the distribution channel is restored.

[0055] In this embodiment, the power management chip is also initialized, and the power management chip and the regional controller are initialized in coordination, thereby reducing the continuous operation time of the power management chip, thereby reducing the probability of power management chip failure and improving the operation effect of the power management chip.

[0056] In some embodiments, before S130, the method further includes: S150. During the operation of the vehicle, the power distribution status information of the power distribution channel is recorded in a storage area.

[0057] That is, during the operation of the vehicle, the power distribution status information of the power distribution channel of the regional controller is recorded in the storage area of ​​the vehicle (the storage area may be a non-volatile memory, for example) to achieve real-time recording of the power distribution status of the power distribution channel of the regional controller.

[0058] For example, the power distribution status information of the power distribution channel of the regional controller may be recorded periodically, and the period may be, for example, 3s or 5s.

[0059] In some embodiments, S150 may include: monitoring the power distribution status of the power distribution channel during vehicle operation; and in response to detecting a change in the power distribution status of the power distribution channel, recording power distribution status information corresponding to the changed power distribution status of the power distribution channel in a storage area.

[0060] That is to say, the vehicle can monitor the power distribution status of the power distribution channel of the regional controller, and after the power distribution status of the power distribution channel of the regional controller changes, the power distribution status information after the power distribution status of the power distribution channel of the regional controller changes can be immediately recorded in the storage area of ​​the vehicle to realize real-time recording of the state changes of the power distribution status of the power distribution channel of the regional controller.

[0061] S160 : In response to the completion of the initialization of the regional controller and the reason for the initialization of the regional controller being a failure of the regional controller, obtain the last recorded power distribution status information for the power distribution channel from the storage area as the output status information of the target power distribution channel.

[0062] After the initialization of the regional controller is completed, the reason for the initialization of the regional controller is continued to be determined. When it is determined that the reason for the initialization of the regional controller is a failure of the regional controller, the distribution status information recorded for the distribution channel for the last time is obtained from the storage area and used as the output status information of the target distribution channel. Therefore, after the initialization of the regional controller is completed, the distribution status of the distribution channel of the regional controller can be restored to the distribution status before the failure.

[0063] Accordingly, if it is determined that the reason for zone controller initialization is not a zone controller failure, the step of restoring power distribution to the distribution channel based on the output status information of the target distribution channel can be omitted. The zone controller can respond to other vehicle signals to change the power distribution status of the zone controller's distribution channel. This is because the reasons for zone controller initialization may vary. If the reason for zone controller initialization is not a zone controller failure, it means that there is no need to restore the power distribution status of the zone controller's distribution channel. Therefore, the step of restoring power distribution to the distribution channel based on the output status information of the target distribution channel can be omitted.

[0064] In this embodiment, the power distribution state of the power distribution channel of the regional controller can be restored to the power distribution state before the fault, thereby improving the accuracy and effectiveness of the restoration of the power distribution state of the regional controller.

[0065] In order to understand the solution of the present application more clearly, the vehicle control method of the present application is explained below with reference to an example. Figure 5 shown.

[0066] S501. Record the power distribution status information in real time according to the power distribution status of the power distribution channel and save it to non-volatile storage; perform a periodic dog feeding operation on the watchdog module of the power management chip; wherein, the periodic dog feeding operation of the watchdog module can be achieved by periodically sending a dog feeding signal to the watchdog module; S502: Does the regional controller have unexpected behavior? If so, execute S503; if not, end the control process. S503, the watchdog module triggers a reset signal; the power management chip outputs a self-locking signal for power distribution; wherein, the watchdog module triggers a reset signal means that the watchdog module determines that the timing period has timed out, the power management chip generates a reset signal, and the power management chip continues to generate a self-locking signal based on the reset signal.

[0067] S504: Check whether the zone controller is initialized. If so, execute S505; if not, terminate the control process. S505. Initialize the power management chip; read the reset type of the zone controller; wherein the reset type can be abnormal reset and normal reset. Abnormal reset means initializing the zone controller when the zone controller fails, and normal reset means initializing the zone controller when the zone controller is normal. The abnormal reset and normal reset can be respectively indicated by the reset type indication information, for example, abnormal reset is indicated by 1, and normal reset is indicated by 0.

[0068] Since the vehicle itself can only identify the initialization performed on the zone controller, but it is difficult to directly identify whether the zone controller is initialized when the zone controller is faulty or when the zone controller is normal, when a reset signal is detected, reset type indication information indicating that the zone controller is initialized when the zone controller is faulty can be generated, and when no reset signal is detected, the reset type indication information is maintained as initializing the zone controller when the zone controller is normal.

[0069] S506: Check if the regional controller is abnormally reset; if so, execute S507; if not, end the control process; S507, read the distribution channel status before reset (target distribution channel output status information), the intelligent distribution sub-system restores the distribution according to the distribution status before reset; S508: Contact the self-locking of the power distribution channel of the regional controller.

[0070] In this example, when an abnormal reset (i.e., initialization) of the zone controller is detected, a self-locking signal is generated to lock the power distribution channel's status. This prevents power loss in the distribution channel during the abnormal reset. After the abnormal reset is complete, the distribution channel's output status is restored using the channel status recorded in the non-volatile storage block.

[0071] See attached Figure 6 , Figure 6 The following is a block diagram of a vehicle control device according to one embodiment of the present application.

[0076] Optionally, the recovery module 630 is further used to monitor the power distribution status of the power distribution channel during vehicle operation; in response to monitoring a change in the power distribution status of the power distribution channel, record the power distribution status information corresponding to the changed power distribution status of the power distribution channel in the storage area.
