Main verification items for automotive ECU communication

The verification projects of automobile ECU communication mainly include network communication test, network management test, diagnostic service test and time synchronization test. Network communication test focuses on communication configuration parameters, bus fault tolerance processing and recovery logic, message interaction, etc., while network management test is mainly to verify the coordinated sleep and wake-up functions. The purpose of diagnostic service test is to confirm the working status of the car and troubleshoot possible faults, while time synchronization test provides a unified time reference for the vehicle system.
