摘要：

       为了提高自适应巡航系统的实用性，在满足《BS ISO-15622》的基本要求下，设计了满足 0~120 km/h的全速域自适应巡航控制（FSRA）方法。基于已有的跟车车间距策略，将前车加速度作 为参考因素，设计了一种符合驾驶员特性的跟车策略。以跟车效率、行车安全性、舒适性、经济性 等作为控制目标，利用模型预测控制（MPC）的方法设计满足多目标优化的控制器，并在SCANeR、 Matlab/Simulink、veDYNA以及NI实时系统的环境下搭建测试平台上对控制方法进行测试和验证。 结果表明：在全速域区间内，该控制方法能较好地完成车辆控制。

Abstract:

 A full speed range adaptive cruise control (FSRA) strategy was designed based on the requirement of BS ISO-15622 to improve the practicality of the adaptive cruise system. Based on the existing vehicleto-vehicle spacing strategy, the acceleration of the preceding vehicle was used as a reference factor to design a follow-up strategy that meets the characteristics of the driver. Taking the following efficiency, safety, comfortability and economy as the control target, model predictive control (MPC) was used to design the controller which met multi-objective optimization. The real time test platform was built in the environment of SCANeR, Matlab/Simulink, veDYNA and NI-PXI system to test and verify the control method. The results show that the control method can complete the vehicle control well in the full speed range.

Key words: full speed range adaptive cruise control (FSRA) , multi-objective , model predictive control (MPC) ,  real time platform test
