Vehicle controller closed loop test system building method, device and equipment

Abstract

The embodiment of the invention discloses a vehicle controller closed loop test system building method, device, equipment and a computer readable storage medium. The method comprises steps: an electronic stability model is generated according to a signal interaction logic of an electronic stability controller; a communication interface of the electronic stability model is defined, wherein the communication interface is used for transmitting signals with a vehicle model and a vehicle controller module; and a closed loop test system is built, wherein the closed loop test system comprises the electronic stability model, the vehicle model and the vehicle controller module in communication connection. According to the method, on the basis of integration of the traditional vehicle controller software and the vehicle model, the electronic stability model can be quickly integrated, the SIL closed-loop automatic test function of the vehicle controller, the electronic stability controller and the vehicle model can be realized, the functions related to the vehicle controller and the electronic stability controller can be quickly verified, and while complex logic function test is met, the testscene effectiveness is ensured, and the test efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a method for establishing a closed-loop test system for a vehicle controller, a device for establishing a closed-loop test system for a vehicle controller, and a device for establishing a closed-loop test system for a vehicle controller And a computer readable storage medium. Background technique [0002] SIL (software in loop, software-in-the-loop simulation) testing is a software testing method, which is used to verify whether the code generated by compiling the control strategy model meets the functional requirements on the computer. This method is commonly used in the vehicle testing process in vehicle production. Test VCU (vehicle control unit, vehicle controller). [0003] ESP (electronic stability program, electronic stability program) is a general term for a system or program designed to improve the handling performance of the vehicle and effectively prevent th...
