The invention provides a radar auxiliary driving system and method, and the system comprises an instrument, a controller, and a radar, and the radar and the controller are connected with the instrument. The controller is used for collecting the absolute vehicle speed of the current vehicle and sending the absolute vehicle speed to the instrument. The instrument is used for sending absolute vehicle speed to the radar; the radar is used for receiving absolute vehicle speed sent by the instrument; collecting the speed of the target object and the distance between the current vehicle and the target object, and obtaining the collision time according to the absolute vehicle speed and the speed and distance of the target object; determining a target object category according to the relationship between the collision time and the absolute vehicle speed, and sending a function flag bit to the instrument according to the target object category; the instrument is used for emergency deceleration or alarm according to the function flag bit; determining the type of the target object according to the relation between the collision time and the absolute vehicle speed, so that the road condition information is accurately judged, the braking effect is good, and it is ensured that braking is conducted within the safe distance.

    本发明提供了雷达辅助驾驶系统和方法,包括仪表、控制器和雷达,雷达和控制器分别与仪表相连接;控制器用于采集当前车辆的绝对车速,并将绝对车速发送给仪表;仪表用于将绝对车速发送给雷达;雷达用于接收仪表发送的绝对车速;并采集目标对象的速度和当前车辆与目标对象的距离,根据绝对车速、目标对象的速度和距离,得到碰撞时间;根据碰撞时间与绝对车速的关系确定目标对象类别,根据目标对象类别向仪表发送功能标志位;仪表用于根据功能标志位进行紧急减速或报警;根据碰撞时间与绝对车速的关系,确定目标对象的类别,从而对路况信息进行精准判断,制动效果好,确保在安全距离内进行刹停。
