Automatic test method and system for vehicle control unit

Abstract

The invention relates to the field of vehicle testing and provides an automatic testing method and system for a vehicle control unit. The method comprises steps of obtaining an automatic testing request, querying an attribute use case association table based on the automated test request to determine a target use case attribute module corresponding to the automated test request, the attribute usecase association table comprising a plurality of use case attribute modules, and each use case attribute module pointing to a different test case; and calling a pointed target test case based on the determined target case attribute module, and executing an automated test. The method is advantaged in that automatic testing is realized to replace manual testing, in addition, professional test engineers do not need to understand test case codes which are difficult to understand professionally, only a table look-up request for the case attribute module needs to be sent out, test operation is completed with high automation degree, the application range of the automatic test is widened, and test cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an automatic testing method and system for a vehicle controller. Background technique [0002] With the gradual improvement of people's awareness of environmental protection, the purpose of new energy vehicles including pure electric vehicles and hybrid vehicles is to reduce emissions, which is considered to be one of the effective paths for energy saving and emission reduction. The vehicle controller (Vehicle Control Unit, VCU) judges the driver's driving intention by collecting signals such as the accelerator pedal, gear position, and brake pedal of the electric vehicle, monitors the vehicle status (vehicle speed, temperature, etc.) The system or the power battery system sends the vehicle's running state control command, and at the same time controls the working mode of the on-board power system. The vehicle controller is the core component of electric vehicles, which ...
