Abstract

The invention relates to an ECU diagnosis configuration code verification method and system and an electronic control unit. The method comprises the steps that: an ECU receives a diagnosis configuration code sent by diagnosis equipment; the ECU judges whether a value of the diagnosis configuration code is within a preset range or not according to a preset rule; if so, the ECU sends a negative response code to the diagnosis equipment; if not, the ECU sends a positive response code to the diagnosis equipment, obtains a CAN bus node signal of a vehicle corresponding to the diagnosis configuration code, compares a CAN bus node signal with the diagnosis configuration code, preliminarily judges that the diagnosis configuration code is written correctly if the CAN bus node signal is consistent with the diagnosis configuration code, and judges that the diagnosis configuration code is written wrongly if the CAN bus node signal is not consistent with the diagnosis configuration code; and if the diagnosis configuration code is preliminarily judged to be written correctly, whether the diagnosis configuration code is consistent with customized vehicle type configuration information is checked. According to the ECU diagnosis configuration code verification method and system, the problem of difficulty in checking customized vehicle model diagnosis configuration codes in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of vehicle ECUs, in particular to a method for verifying ECU diagnostic configuration codes, a system thereof, and an electronic control unit. Background technique [0002] At present, many OEMs only define the vehicle configuration information. For the same model, all ECUs have the same vehicle configuration code. The off-line configuration system can only check whether the ECU has been assembled. Specifically, the vehicle configuration code is verified by comparing the vehicle configuration information. . Therefore, the existing technology can only judge that the configuration code is within the valid range of the vehicle configuration according to the fixed vehicle configuration table, and can only ensure that the written configuration code is the configuration supported by the vehicle project. [0003] In the process of realizing the present invention, the inventor finds that the prior art has at least ...
