Communication fault diagnosis method and device, control unit and vehicle

Номер: CN116405156A
Автор: WANG SHUNJIE, SONG LINCONG, ZHOU HONGWEI
Принадлежит:

The invention relates to a communication fault diagnosis method and device, a control unit and a vehicle, and relates to the technical field of communication. The communication fault diagnosis method is applied to a receiving end under a service-oriented architecture, and comprises the following steps: receiving a first service message sent by a sending end; the first service message comprises service data, a cyclic redundancy check (CRC) value and a cyclic count value, and the CRC value is generated based on the service data, the identifier of the sending end and the cyclic count value. And verifying the cyclic count value and the CRC value to obtain a verification result of the first service message, and determining a communication state between the sending end and the receiving end according to the verification result of the first service message. The method and the device are used for solving the technical problem that communication faults cannot be effectively diagnosed under an SOA-based ...
