摘　　要：本文针对ESP与EPS协调控制对于车辆稳定性的影响进行分析,着重研究ESP单独控制系统、ESP与EPS协调控制系统对于车辆稳定性影响的差异性;在对ESP与EPS的功能特性进行分析的基础上,选用协调控制参数分配法作为ESP与EPS协调控制的控制策略;再通过Matlab/Simulink搭建相关的试验模型并与Carsim进行联合仿真,进行双移线仿真试验.试验结果表明,ESP与EPS协调控制进一步改善了车辆的质心侧偏角和横摆角速度,提高了车辆的行驶稳定性,优于单一的ESP对于车辆的稳定性控制.This paper analyzes the impact of ESP and EPS coordinated control on vehicle stability,focusing on the difference in the impact of ESP single control system,ESP and EPS coordinated control system on vehicle stability;Based on the analysis of the functional characteristics of ESP and EPS,the coordinated control parameter allocation method is selected as the control strategy for ESP and EPS coordinated control;then the relevant test model is built through Matlab/Simulink,and the Co-simulation is carried out with Carsim to carry out the double-line shift simulation test.The test results show that the ESP and EPS coordinated control system can further improve the vehicle's centroid side yaw angle and yaw rate,improve the vehicle's driving stability,which is better than the single ESP for vehicle stability control.
