用于电子稳定程序的汽车模型和控制策略

电子稳定程序(ElectronicStabilityProgram)是行驶车辆的一种主动安全系统,它综合了制动防抱死系统,驱动力控制系统和横摆力矩控制系统,使行驶车辆的安全性得到很大的提高。本文首先建立用于电子稳定程序的汽车模型,包括车身模型、悬架模型、转向模型、轮胎模型、制动系统模型、发动机模型和传动系模型。然后建立了主动横摆控制的控制逻辑,通过加入制动防抱死系统和牵引力控制系统,构成了电子稳定程序的控制逻辑。最后对移线运动、紧急转向、制动转向、驱动转向4个典型的工况进行仿真,从而验证了电子稳定程序控制逻辑的正确性。

Dynamic Model and Control Method for Motor Vehicle with Electronic Stability Program

This paper is mainly about Electronic Stability Program (ESP),an active safety system which consists of anti-braking system,traction control system and yaw moment control,can improve the safety of the vehicle greatly.In this paper we firstly build a vehicle dynamic model,including vehicle body,suspension system,steering system,tire model,braking system,engine model and transmission model.Then we build the control logic of active yaw control,by adding anti-braking system and traction control system which constitute the ESP controller.Finally we simulate ESP controller in four typical conditions of lane change,J-turn,steering under braking and steering to validate the efficiency.
