The invention provides an intersection vehicle anti-collision method and device. The intersection vehicle anti-collision method comprises steps that the first time from a target vehicle to an intersection point of an intersection, the second time from a current vehicle to the intersection point of the intersection and a driving distance from a current vehicle to the intersection point of the intersection are obtained, whether the difference value between the first time and the second time is smaller than or equal to preset safety collision time or not is determined, if yes, a braking distanceof the current vehicle is calculated, and a control instruction of the current vehicle is outputted according to the braking distance and the driving distance. The intersection vehicle anti-collisionmethod is advantaged in that through the wireless communication technology for the vehicle, when the current vehicle possibly collides with the target vehicle at the intersection point of the intersection, a control instruction of the current vehicle is outputted according to the braking distance of the current vehicle and the driving distance from the current vehicle to the intersection point ofthe intersection so that the current vehicle is prevented from colliding with a target vehicle, and the risk of collision of the vehicles at the intersection is effectively reduced.

    本申请提供一种交叉路口车辆防碰撞方法及装置,交叉路口车辆防碰撞方法,包括:获取目标车辆到交叉路口交汇点的第一时间、当前车辆到交叉路口交汇点的第二时间及当前车辆到交叉路口交汇点的行驶距离;判断所述第一时间与第二时间的差值是否小于等于预设的安全碰撞时间;若是,则计算当前车辆的刹车距离;根据所述刹车距离及所述行驶距离,输出当前车辆的控制指令。本申请交叉路口车辆防碰撞方法及装置,通过车用无线通信技术,在当前车辆与目标车辆在交叉路口交汇点可能发生碰撞时,根据当前车辆的刹车距离及其到交叉路口交汇点的行驶距离,输出当前车辆的控制指令,用以防止当前车辆与目标车辆发生碰撞,有效降低交叉路口车辆发生碰撞的风险。
