  • In order to study the influence of wheelbase preview control technology on the performance of semi-active suspension system, a half-vehicle semi-active suspension model based on wheelbase preview was established. Neural networks and PID control theory were utilized, the control algorithm of single neuron adaptive PID was put forward, the single neuron PID control system of semi-active suspension based on wheelbase preview was designed, and the simulation was carried out. In order to study the effectiveness of the single neuron adaptive PID control strategy and the reliability of control system, vehicle road test was carried out. Analysis result shows that compared with the passive system, the peak and standard deviation separately decrease by 20. 91% and 19. 11% at the speed of 50 km·h-1, and decrease by 24.42% and 26.85% at the speed of 60 km·h-1, and the pitching angular aeeeleration is also reduced at a certain degree, so the vehicle ride performance is improved significantly.
