Vehicle control unit operation method and system and electronic control unit

Abstract

The invention relates to the technical field of vehicle testing, and provides a vehicle control unit operation method and system and an electronic control unit, and the method comprises the steps: receiving a user operation, and obtaining a vehicle testing request corresponding to the user operation; analyzing the whole vehicle test request, and determining a whole vehicle test signal set corresponding to the whole vehicle test request, wherein the whole vehicle test signal set comprises a plurality of whole vehicle test signals pre-calibrated with an execution sequence; sequentially generating vehicle test signals according to the execution sequence, and sequentially sending the generated vehicle test signals to a vehicle controller so as to automatically and sequentially test the functions of the vehicle controller. Therefore, the automatic test process of multiple vehicle functions of the vehicle control unit can be completed based on user operation, the problems of function test omission and misoperation caused by manual operation of test signals or test functions are avoided, and the comprehensiveness and accuracy of test result data are guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an automatic testing method, system and electronic control unit for a vehicle controller. Background technique [0002] As emission regulations become more and more stringent and the energy crisis becomes more and more serious, new energy vehicles have become the current and future development trend of automobiles. Among them, the vehicle controller, as the core component of the vehicle, judges the driver's driving intention by collecting signals such as the accelerator pedal, gear position, and brake; and coordinates the various units of the vehicle power system by monitoring the vehicle status (vehicle speed, temperature, etc.) functions to realize the power, economy, fault diagnosis, protection and storage functions of the vehicle. Therefore, after the vehicle is rolled off the assembly line, it is necessary to conduct comprehensive testing and debugging on the hardwa...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims to propose a method for automatic testing of the vehicle controller, to at least solve the problem of omissions and errors in the testing process due to the need for manual operations to test the multiple operations of the vehicle functions in the prior art. operation, and issues with missing or inaccurate test result data
