The invention provides an intersection early warning method and device, and the method comprises the steps: firstly obtaining basic data which comprises the geometric parameters and motion information of a vehicle, and the relative position information of the vehicle and a target vehicle as a potential dangerous target at an intersection, and determining the current driving behavior of the vehicle based on the geometric parameters and motion information of the vehicle, the driving path of the vehicle and the driving path of the target vehicle corresponding to the current driving behavior of the vehicle are determined by combining the relative position information, collision parameters between the vehicle and the target vehicle are further determined on the basis of the driving path of the vehicle and the driving path of the target vehicle, and the collision parameters comprise collision time and transverse displacement of a collision point; and finally, selecting a dangerous target vehicle with the shortest collision time from the target vehicles, and performing intersection early warning according to the collision time corresponding to the dangerous target vehicle and the transverse displacement of the collision point.

    本发明提供一种路口预警方法及装置,首先获取基础数据,该基础数据中包括本车的几何参数和运动信息、以及本车与作为路口潜在危险目标的目标车辆的相对位置信息,进而基于本车的几何参数和运动信息确定本车当前的行驶行为,并结合相对位置信息确定与本车当前的行驶行为相对应的本车的行驶路径和目标车辆的行驶路径,进一步基于本车的行驶路径和目标车辆的行驶路径确定本车与目标车辆间的碰撞参数,该碰撞参数包括碰撞时间和碰撞点的横向位移,最后从目标车辆中选择碰撞时间最小的危险目标车辆,并依据危险目标车辆对应的碰撞时间和碰撞点的横向位移进行路口预警。
