The invention provides a vehicle-based collision early warning method, device and equipment. The method comprises the steps that the driving speed of an adjacent vehicle in a lane adjacent to a lane where a vehicle is located and the first distance of the adjacent vehicle are acquired, and the movement speed of a crossing traffic participant which performs crossing action in front of the vehicle and the second distance of the crossing traffic participant are acquired; predicting the moving distance of crossing the traffic participant; and if it is determined that the crossing traffic participant will enter the collision area when the adjacent vehicle arrives at the collision area according to the second distance, the length of the collision area and the moving distance, sending a first early warning to the adjacent vehicle and the crossing traffic participant. According to the method, early warning errors caused by network signal loss and delay are avoided; through a mode of simultaneously reminding adjacent vehicles and crossing traffic participants, when any one party is aware of danger and reduces the speed, the risk of ghost probe collision between the two parties can be reduced, and the occurrence of ghost probe accidents is reduced.

    本申请提供一种基于车辆的碰撞预警方法、装置和设备。该方法包括:通过获取与自车所在车道相邻车道内的相邻车辆的行驶速度、以及相邻车辆的第一距离,并获取位于自车的前方进行横穿动作的横穿交通参与者的运动速度、以及横穿交通参与者的第二距离;再预测横穿交通参与者的移动距离;若根据第二距离、碰撞区的长度以及移动距离,确定横穿交通参与者在相邻车辆抵达碰撞区内时,会进入碰撞区之内,则向相邻车辆和横穿交通参与者发出第一预警。该方法,避免了因网络信号丢失和延迟带来的预警误差;通过同时提醒相邻车辆和横穿交通参与者的方式,当任一一方意识到危险并降低速度后,就可以降低两者发生鬼探头碰撞的风险,减少了鬼探头事故的发生。
