| Abstract: | The single wheel vehicle model was adopted as a research object in the paper. Mathematical models for an en- tire car, a bilinear tire model, a hydraulic brake model and a slip ratio calculation model were established in the Mat- lab/Simulink environment. The PID controller was designed. The established ABS mathematical model was simulated and re- searched and the simulation curves were obtained. The simulation results were compared with the results without ABS. The re- sults show that established models were reliable and could achieve desirable brake control effects. |
