Abstract
In order to study the influence of tire pressure change on the control of vehicle handling stability, the seven-degree-of-freedom theoretical model of automobile dynamics and tire theoretical model considering tire pressure were established. Considering the double lane conditions, the control stability of automobile is simulated, and the influence of tire pressure change on the control stability of automobile is analyzed. The simulation results show that when the tire pressure is too high or too small, the yaw rate of the vehicle in the process of high speed steering cannot be stable, which reduces the vehicle handling stability.
