Description

Technical Field

[0001] This application relates to the field of vehicle networking, and in particular to a method, device and storage medium for managing the watchdog function of vehicle networking. Background Technology

[0002] A watchdog timer is a module or separate chip in a microcontroller. Its main function is to generate a reset signal, causing the microcontroller to reset and restart when it enters a fault state. When a microcontroller encounters a strong magnetic field or has a flawed program design, it may malfunction, enter an infinite loop, and disrupt normal operation, causing the microcontroller control system to fail. A watchdog timer can restart the out-of-control microcontroller, escaping the malfunction.

[0003] Once the watchdog timer is enabled, it must be periodically fed to prevent the microcontroller from being restarted. When the microcontroller enters sleep mode, the watchdog feeding task cannot run in sleep mode. Failure to periodically feed the watchdog timer will cause the microcontroller to restart. As a result, the microcontroller cannot enter sleep mode and keeps preparing to enter sleep mode and then restarting in a cycle, causing program disorder. Therefore, it needs to be improved.
