摘要
自适应巡航系统能保持安全车距,是现代汽车主动安全系统的重要组成部分。文章利用机械动力学仿真软件ADAMS/CAR建立JETTA GTX轿车整车动力学模型,对难以描述的部分采用基于实验的半经验模型,通过输入输出接口实现同MATLAB的联合仿真,对各种工况下ACC系统控制过程中车辆的动态特性进行研究,此模型较准确地反映了ACC控制过程车辆各相关参数的变化情况,可以作为进行实车ACC控制算法开发的基础,为加快开发轿车ACC系统的控制逻辑提供了理论依据。该模型还可进行ABS/ASR/ACC集成化系统仿真。
Adaptive Cruise Control（ACC） system is a very important Subsystem of modern active safety system which can hold safety distance between tow vehicles. An ACC Co - simulation model for JETTA GTX is presented in this article. ADAMS/CAR is used to build ACC mechanical dynamics model and MATLAB is used to build the control model of ACC. A semi empirical model is used to describe some important subsystems that are difficult to be described with formula. The Co - simulation model is exact enough to describe the vehicle＇s characteristic during ACC control stage and can simulate vehicle＇s dynamic response with the control of ACC under various operating conditions. As a result, it is very useful to speed up the development of ACC, and can also be used to research the ABS/ASR/ACC integrated system.
