中文摘要：

汽车稳定性控制系统（Dynamics stability control stystem,DSC）是汽车主动安全领域的一项关键技术,长期以来一直是汽车领域的研究热点.DSC系统集成汽车防抱制动系统（Anti-lock braking system,ABS）、牵引力控制系统（Traction contort system,TCS）以及主动横摆力偶矩控制系统（Activeyam control,AYC）,能有效改善汽车的稳定性和安全性.汽车稳定性控制技术的发展可分为动力学建模、状态观测、控制策略和产业化四个方面.其中动力学建模包括面向仿真的建模和面向控制的建模.面向仿真的建模可采用ADAMS或Carsim建立仿真模型,面向控制的建模可采用两轮或四轮模型.状态观测主要需要对动力学控制关键参量如轮缸压力、路面附着、轮胎力和纵横向车速等进行在线观测.在已实现DSC控制的基本功能后,对DSC控制的要求进一步提高,为了减少控制的滞后性,介绍基于预测横摆角速度的AYC控制策略,同时为了减少汽车在对开路面上的抖动,介绍防抖振的TCS控制技术.通过不断的探索和研究,稳定性控制技术在国内的产业化也逐步在实现.

英文摘要：

vehicle dynamics stability control system（DSC） is a key technology of vehicle active safety system, and it has been a hot research issue in vehicle field for a long time. The DSC system which is integrated with anti-lock braking system（ABS）, traction control system（TCS） and active yaw control（AYC） can improve the stability and safety of vehicle significantly. The research progress of vehicle dynamics stability control system can be classified into modeling, state observation, control strategy and industrialization. The modeling includes the modeling in simulation and the modeling in control. ADAMS or Carsim can be adopted to build the vehicle model for simulation. Two wheels model or four wheels model usually are used in control. The state observation mainly focuses on the pressure estimation of the wheel cylinder, the estimation of road friction, the estimation of tire forces, the estimation of longitudinal and lateral velocity. After the realization of the basic function of vehicle stability control, the requirement for control is increasing gradually. A new AYC control strategy which is based on the predicted yaw rate is introduced to reduce the hysteresis of control. Meanwhile a new kind of TCS control strategy is introduced to reduce the vehicle vibration on uneven low-adhesion road. Through the unremitting exploration and research, the industrialization of DSC is gradual realizing.
