Abstract：Vehicle braking stability directly affects vehicle safety. Based on the linear two-degree-of-freedom vehicle model， a nonlinear three-degree-of-freedom vehicle model is established. Based on the model predictive control theory， the vehicle braking stability performance MPC controller is designed. The control strategy of automobile braking stability is analyzed and studied. Under different road conditions， the article uses the MATLAB simulation tools to simulate two driving conditions of automobile double-shift steering angle input and J-turn steering angle input. Research and simulation results show that the use of the designed model predictive control method is helpful to improve the quality of braking system stability control.
