Abstract

In urban traffic, frequent accelerating and decelerating of a vehicle can cause the vehicle to pitch and rock, causing discomfort and even motion sickness.Based on the particle swarm optimization-based control and PID control, a continuously adjustable anti-pitch hydraulic interconnected suspension system was proposed.A semi-vehicle model including the brake system, tire and hydraulic interconnected suspension system was established.and the factors affecting the stiffness and damping characteristics of the hydraulic interconnected suspension,the pitch control and the ride comfort were analyzed.The Skyhook and PID controllers were designed, and the control parameters were set by using the particle swarm optimization algorithm.The linear braking conditions were simulated by combined use of the softwares of Simulink and Amesim, and the smoothness optimization effect and braking safety under the proposed control strategy were analyzed.The results show that the semi-active anti-hydraulic interconnected suspension can more effectively improve the ride comfort of the vehicle compared to the passive suspension.
