Virtual Validation and Verification Method of Brake System Model

Model validation needs effective and efficient after development of the brake model. For the relatively high cost and limited coverage of test condition of the experimental verification, a virtual test environment of the brake system is established by using the vehicle model and the graphical interface of mature vehicle dynamics simulation software Carsim. Firstly, the brake system model is encapsulated into a dynamic link library. Then the new brake model according to the relationship between input and output of the brake system and vehicle through the S-function is integrated with Carsim vehicle model in Matlab/Simulink, replacing the Carsim brake model. Finally, the mixed model is verified though comparing with Carsim vehicle model in the same operation condition. The simulation results show that the validation and verification method are effective and low cost.
