AI Technical Summary

Technical Problem

In the prior art, the protocol type by polling each ECU during vehicle diagnosis is inefficient, especially when there are multiple ECUs inside the vehicle, diagnostic protocol commands need to be sent one by one to determine the correct protocol type, resulting in inefficient diagnosis.

Method used

The pre-generated gateway protocol correspondence table is adopted, and the corresponding communication protocol is directly selected according to the communication connection request to establish a connection with the vehicle electronic control unit, avoiding the polling process and improving diagnostic efficiency.

Benefits of technology

By directly selecting the appropriate communication protocol, the efficiency of vehicle diagnosis is significantly improved, the diagnosis time is reduced, and the compatibility and reliability of the system are enhanced.

Abstract

The invention discloses a vehicle communication diagnosis method and device, equipment, a storage medium and a program product, and relates to the technical field of vehicle diagnos.The method comprises the steps that a vehicle diagnosis request and a communication connection request are received; based on a pre-generated gateway protocol corresponding table, according to the communication connection request, selecting a corresponding communication protocol to establish communication connection with a corresponding vehicle electronic control unit; according to the vehicle diagnosis request, vehicle diagnosis is conducted on the vehicle electronic control unit with the communication connection established, and a vehicle diagnosis result is obtained. According to the method, the corresponding communication protocol is directly selected to establish the communication connection with the corresponding vehicle electronic control unit based on the gateway protocol corresponding table according to the communication connection request, and the diagnosis protocol type of each vehicle electronic control unit is recorded in the gateway protocol corresponding table. The problem of low efficiency of vehicle diagnosis by determining the diagnosis protocol through polling the diagnosis protocol type is solved, and the efficiency of vehicle diagnosis is improved.
