The invention discloses a vehicle collision early warning method and device. The method comprises the steps of: predicting the moving track of a target object, and obtaining a target driving path of atarget vehicle; determining the position of a predicted collision point between the target vehicle and the target object according to the moving track and the target driving path; and acquiring current motion parameters of the target vehicle, and performing vehicle collision early warning according to the position of the predicted collision point and the current motion parameters. Visibly, even if the target vehicle and the target object simultaneously run on a curve, the target vehicle can determine the position of the predicted collision point by predicting the moving track of the target object and the driving path of the target vehicle, so that the vehicle collision early warning is triggered in time based on the position of the predicted collision point, the effectiveness of the vehicle collision early warning is further ensured, and the vehicle driving safety of a driver is improved.

    本申请公开了一种车辆碰撞预警方法及装置,包括:预测目标对象的移动轨迹,并获取目标车辆的目标行驶路径;根据移动轨迹以及目标行驶路径,确定出目标车辆与目标对象之间的预测碰撞点的位置;获取目标车辆的当前运动参数,并根据预测碰撞点的位置以及当前运动参数进行车辆碰撞预警。可见,即使目标车辆与目标对象同时位于弯道上行驶,目标车辆也能通过预测出目标对象的移动轨迹与目标车辆的行驶路径确定出预测碰撞点的位置,从而基于预测碰撞点的位置及时触发车辆碰撞预警,进而保证了车辆碰撞预警的有效性,提高了驾驶员驾驶车辆的安全性。
