摘要
为实现智能车辆的自适应巡航功能,基于车速跟踪及PID控制理论设计了具有上下两层结构的自适应巡航控制系统.下层控制器根据上层控制器计算出的期望车速对节气门开度和制动力矩进行协调控制.在保证控制精度的前提下简化了算法.多种工况下的仿真实验表明控制器的控制效果良好.
To realize intelligent vehicle＇s self-adaption cruise function, an adaptive cruise control system with a two-level structure has been designed based on the speed tracking and PID control theory. The lower control- ler can control throttle angle and brake torque coordinately so as to make the vehicle follow the desired speed that calculated by the upper controller. The algorithm guaranteed the control accuracy and is simplified. Sim- ulation results show that the performance of the controller is satisfactory.
