Abstract: In the traditional proportion integral differential (PID) power steering stability modelling and control algorithm, the road control process lacks auxiliary control, the real-time performance is poor, and the stability is low. In view of this situation, a stability modelling and control algorithm of electric vehicle steering system is proposed. The simulation models of steering system, motor system and frame system are established by using the simulation tools of MATLAB software. The test results show that the lateral acceleration control algorithm of electric vehicle is -0.4 to -0.72 g, 17.5 degrees/s and 22 degrees/s respectively under the control of input angle of 3 degrees/s to 17.5 degrees/s, stability of 22 degrees/s, stability of 0.4 to -0.3 g and -0.33 to -0.72 g.
