The current test simulation system mainly includes software simulation test, pulley test, real vehicle crash test, etc. The software simulation is to use computer software to simulate the hardware composition of the controller and the controller program, and observe the reaction of the program when it receives different acceleration data. However, the existing The accuracy of the test simulation system is not high. For example, the sliding block test makes the controller receive the acceleration curve close to the ideal collision through the mechanical transmission. The mechanical structure is complex and cannot produce complicated acceleration changes. The test cost is high and the cycle is long. Obviously, the existing test simulation system can no longer meet the actual use requirements
