基于单片机的汽车巡航控制系统[外文翻译].doc

Adaptive Cruise Control (ACC) is an automotive feature that allows a vehicle's cruise control system to adapt the vehicle's speed to the traffic environment. A radar system attached to the front of the vehicle is used to detect whether slower moving vehicles are in the ACC vehicle's path. If a slower moving vehicle is detected, the ACC system will slow the vehicle down and control the clearance, or time gap, between the ACC vehicle and the forward vehicle. If the system detects that the forward vehicle is no longer in the ACC vehicle's path, the ACC system will accelerate the vehicle back to its set cruise control speed. This operation allows the ACC vehicle to autonomously slow down and speed up with traffic without intervention from the driver. The method by which the ACC vehicle's speed is controlled is via engine throttle control and limited brake operation.
自适应巡航控制系统(ACC)是一种汽车功能,允许车辆在巡航控制系统控制下行驶在适应车辆速度的交通环境。配置有一个雷达系统安装在车辆前部用来检测运动缓慢车辆是否在该车辆的前方道路上，如果前方发现一辆行驶速度较低的汽车,自适应巡航控制系统将减慢速度控制与前车的距离,或者两车的时间间隔。如果系统发现向前的汽车不再是在ACC车辆的路径,ACC系统将会加速使汽车回到它的设置巡航控制速度。该操作允许ACC车辆自动减速和加速而不经过司机的控制干预。控制方法是通过发动机油门控制和有限刹车操作达到速度的控制。
