摘要： 动力学稳定性控制（dynamics stability control, DSC）系统可以提高汽车的稳定性。DSC 控制逻辑中名义
横摆角速度的选取直接和汽车稳定性因数相关。考虑到动力学稳定性控制干预的极限工况下，汽车大联合滑移、大
横向加速度特征，需要对汽车动态稳定性因数进行分析，进而设计出能够融合汽车动态转向特性的综合稳定性因数，
作为DSC 控制器的关键控制参量。该文对某轿车利用ADAMS 软件动力学仿真以及实车测试方法，并结合整车动力学
参数对转向特性进行分析，得到综合稳定性因数。在此基础上通过极限工况移线试验验证其有效性。

Abstract: Dynamics Stability Control (DSC) improves the vehicle stability. The selection of the nominal values of the yaw rate
in the DSC control logic relates directly to the vehicle stability coefficient. In consideration of the characteristics of the vehicle
with high slip and high lateral acceleration for limit conditions of dynamics stability control, analyzing the stability coefficient is
needed to design the compositive stability coefficient as the key control parameter for the DSC controller. This paper contraposed
a certain style of passenger car, using both the ADAMS dynamic simulation and real car test methods to analyze the steering
characteristics with whole vehicle dynamic parameters to obtain the compositive stability coefficient. The limit condition of lane
change test verifies the validity of the coefficient.

Key words: vehicle dynamics, steering characteristics, stability coefficient, limit condition
