摘　　要：探讨主动制动控制系统在汽车自适应巡航控制中的作用.对主动制动采用基于加速度的控制方案,给出了主动制动系统的硬件组成.为了实现期望加速度跟随控制,在理论和试验的基础上建立了用于求解期望制动压力的车辆制动逆动力学模型.利用改进的PID算法开发了制动压力控制器.实车试验证明,制动压力和加速度控制效果都达到了自适应巡航系统对主动制动控制的要求.The function of active braking in the adaptive cruise control system was discussed,the strategy based on acceleration control was employed and the configuration of the active braking system was introduced.In order to calculate the desired braking pressure,a converse vehicle braking model was built based on the dynamic analysis and experiments.Using the improved PID control algorithm,the pressure controller has been developed.Experiments indicate that both the pressure and acceleration control meet the requirements of adaptive cruise control system for active braking control.
