Co-Simulation Study for Fuzzy ESP Control Strategy on Vehicle

摘要

ESP can help the road vehicle to improve driving dynamics and prevent accidents which result from loss ofcontrol. Based on the theory and account method of Multi-body System Dynamics, the Multi-body System Dynamicsmodel of an A-class car is built by the ADAMS/Car software, which includes steering system, front and rear suspension,braking system, body, and so on. In order to study the handling stability of vehicle with ESP control system, the vehicleyaw rate is set as the controlling aim, to build the fuzzy controller of ESP. The performance evaluation methods of vehiclewith ESP are proposed to evaluate the handling stability of vehicle with ESP. The results show that the vehicle with ESPcan keep the right path, the yaw rate and the vehicle slip angle is all controlled better. The handling stability of vehicle canbe improved.
