The invention discloses a collision early warning system for a vehicle, the system is composed of a road end and a vehicle end, the vehicle end comprises: a vehicle-mounted communication unit configured to receive a road surface condition of a road on which the vehicle is traveling from the road end; a tire information module configured to determine a friction coefficient of a wheel based on a pavement condition of a road on which the vehicle is traveling, the tire information module further configured to determine a current traveling speed of the vehicle; a vehicle-mounted calculation unit configured to calculate a safe braking distance of the vehicle based on the friction coefficient of the wheels determined by the tire information module and a current driving speed of the vehicle; and the vehicle-mounted radar is configured to detect the actual vehicle distance between the vehicle and the adjacent vehicle in front, and the vehicle-mounted calculation unit is further configured to compare the safety braking distance with the actual vehicle distance and send a corresponding collision early warning signal to a vehicle driver based on a comparison result. The invention further discloses an operation method of the collision early warning system.
本发明公开了一种用于车辆的碰撞预警系统,该系统由路端和车端两大部分构成,所述车端包括:车载通信单元,其配置为从所述路端接收车辆正在行驶道路的路面状况;轮胎信息模块,其配置为基于车辆正在行驶道路的路面状况确定车轮的摩擦系数,该轮胎信息模块还配置为确定车辆当前的行驶速度;车载计算单元,其配置为基于由所述轮胎信息模块确定的车轮的摩擦系数和车辆当前的行驶速度计算车辆的安全制动距离;以及车载雷达,其配置为检测车辆与前方相邻车辆之间的实际车距,所述车载计算单元还配置为将所述安全制动距离与所述实际车距进行比较,并基于比较结果向车辆驾驶员发送相应的碰撞预警信号。本发明还公开了该碰撞预警系统的操作方法。
