摘要/Abstract

摘要： 针对驾驶员引起的汽车侧翻问题，分析驾驶员因素影响汽车侧翻稳定性的机理，提出融合驾驶员的人-车闭环系统差动制动防侧翻控制策略。考虑驾驶员感知、决策及执行参数的影响，建立驾驶员侧倾反应动力学模型；以某SUV为对象，分析驾驶员侧倾反应模型主要参数影响汽车侧翻稳定性的规律，包括驾驶经验参数、神经系统延迟时间及肌肉系统延迟时间；融合驾驶员及电控液压制动系统动力学特征设计PID差动制动防侧翻控制策略；选取典型汽车侧翻工况进行实例验证，结果表明驾驶员经验参数和神经系统延迟时间对汽车侧翻稳定性影响显著；提出的融合驾驶员的人-车闭环系统差动制动防侧翻控制策略既可弥补驾驶经验不足又可克服驾驶员生理及心理限制的限制，有效提高汽车防侧翻能力。

Abstract: Driver's operation is dominant factor in vehicle rollover accident. In order to explore the mechanism of vehicle rollover caused by driver's operation, the rollover stability of a driver-vehicle closed loop system is analyzed and the differential braking control strategy is put forward for vehicle rollover prevention. Taking the perception, decision-making and execution parts of the driver into consideration, a multiple degrees of freedom dynamic model of the driver-vehicle closed loop system is established. From the model, the laws of the vehicle rollover stability affected by the main parameters of the driver are discussed, including the driver's experience parameters, neuron delay time, and muscular delay time. Also, the anti rollover control strategy is presented using the PID differential braking method based on the dynamics of the driver-vehicle closed loop system and the electro hydraulic braking (EHB) device. Furthermore, some numerical simulations are given for a sport utility vehicle (SUV) rollover in typical cases. The results show that the parameters of the driver's experience and neuron delay time exert an important effect on vehicle rollover stability, and the proposed control strategy can effectively improve active safety for vehicle anti-rollover.

Key words: anti-roll control, driver-vehicle closed loop system, electro hydraulic brake, rollover stability
