Abstract
The application provides a test method, a system, an electronic device and a storage medium for AMT gear shifting, and relates to the technical field of vehicles.The test method comprises the following steps: determining a selection boundary value and a gear shifting boundary value according to a gear shifting motor position sensor; creating a HIL gear shifting model according to the selection boundary value and the gear shifting boundary value; controlling a TCU to output a driving signal; controlling the HIL gear shifting model to perform instruction recognition on the driving signal; and controlling the HIL gear shifting model to simulate the gear shifting motor state according to the recognized driving instruction.The HIL test of the AMT electric control gear shifting can be conveniently and efficiently completed.The problems that a certain specific test working condition cannot be accurately reproduced, the related strategy verification and calibration work can only be started after the completion of the whole vehicle prototype, and the test cost is high in the prior art are solved.
