The invention provides a vehicle, a collision identification method and device thereof, and equipment. The collision identification method comprises the steps of: detecting a barrier vehicle in a preset range in front of the vehicle; when the obstacle vehicle is detected, acquiring first driving information of the obstacle vehicle; according to the first driving information, acquiring first collision time in the driving direction of the obstacle vehicle and second collision time in the direction perpendicular to the driving direction; acquiring second driving information of the vehicle, and acquiring the minimum braking time of the vehicle according to the second driving information; and according to the first collision time, the second collision time and the minimum braking time, judging whether the collision risk exists between the vehicle and the obstacle vehicle or not. According to the collision identification method, whether the collision risk exists or not is judged in advance before the obstacle vehicle merges into the lane, so that early warning operation can be conveniently carried out on the obstacle vehicle in advance, sudden lane merging of the obstacle vehicle can be prevented in time, the probability of traffic accidents such as collision caused by emergencies is effectively reduced, and the vehicle driving safety is improved.

    本发明提出一种车辆及其碰撞识别方法、装置和设备,其中,方法包括:对本车前方预设范围内的障碍车辆进行检测;当检测到障碍车辆时,获取障碍车辆的第一行驶信息;根据第一行驶信息,获取障碍车辆行驶方向上的第一碰撞时间和与行驶方向垂直的方向上的第二碰撞时间;获取本车的第二行驶信息,根据第二行驶信息,获取本车的制动最小时间;根据第一碰撞时间、第二碰撞时间和制动最小时间,判断本车与障碍车辆是否存在碰撞风险。该方法在障碍车辆并入本车道之前提前判断是否存在碰撞风险,便于提前向障碍车辆进行预警操作,从而可以及时阻止障碍车辆突然并道,有效降低了因突发状况导致碰撞等交通事故发生的概率,提高了驾驶车辆的安全性。
