汽车 ABS／ASR／ESP 集成控制策略研究

摘要

Based on the mathematical models including the nine DOF vehicle dynamics model , engine model , wheel model and transmission model , it designs the control strategy under breaking condition and driving condi-tion.It analyzes the ABS/ASR/ESP integration control system algorithm and develops various parts of the control strategies and process control procedures .This dissertation effectively makes the various parts to determine the integrated control strategy in seeing the braking condition and driving conditions .It simulates the ABS/ASR/ESP integrated control in MATLAB/Simulink, proves the effectiveness of the controller and the advantages of integrat-ed control under various operating conditions .%在对整车及轮胎受力分析的基础上，基于某轿车建立了9自由度整车动力学模型、发动机模型、车轮模型、传动系模型等，根据仿真模型和车辆系统动力学知识对汽车ABS/ASR/ESP集成控制系统中各子系统的触发条件进行了研究，并对ABS/ASR/ESP集成控制策略进行了探讨，确定了集成控制系统在制动工况和驱动工况下统一的控制策略。在MATLAB/Simulink环境下实现车辆ABS/ASR/ESP的集成控制，并通过各个工况的仿真验证了集成控制策略的有效性和集成控制的优势。
