Abstract

The present application provides a vehicle bus fault recording method and apparatus, a device, and a storage medium. The method includes: sending wake-up record messages to a primary domain control node of an ECU according to a preset cycle after the ECU is woken up; receiving, by the primary domain control node, the wake-up record messages sent by at least one ECU controlled by the primary domain control node when it is detected that vehicle sleep fault detection conditions are met; and storing the wake-up record messages of the at least one ECU in a memory of the vehicle. When abnormal battery drain occurs in the vehicle, troubleshooting personnel can search for specific wake-up reasons of the vehicle by the wake-up record messages, thereby improving the efficiency of solving the vehicle battery drain problem.
