In order to improve the impact of vertical, pitch and roll motion of the vehicle in the process of driving, a multiobjective switching control strategy of active suspension is proposed. Based on the extended zero moment point theory, the pitch and roll evaluation indexes of the vehicle in complex terrain are established. The vehicle model is established in ADAMS/Car environment, and the accuracy of the model is verified by real vehicle tests based on random roads. According to the graphical evaluation index and the steering wheel Angle value as the logical judgment condition of state switching, a multiobjective switching control strategy is established on MATLAB/Stateflow, and a multiobjective switching fuzzy PID controller is established based on the control strategy. A certain type of linear motor is selected as the force source of active suspension, and the cosimulation under three different conditions of constant speed driving on Cclass road, double line shifting, acceleration and deceleration up and down slope is carried out by ADAMS/Car and MATLAB/Simulink respectively. The simulation results show that the proposed multi-objective switching control strategy of active suspension effectively reduces the occurrence of vertical, pitch and roll motion of the vehicle, and improves the ride comfort and driving safety of the vehicle as a whole.
