The invention provides a method for estimating the collision time of a vehicle and a vehicle collision early warning device, and the method comprises the steps: 1, estimating the basic collision time of a first current vehicle; comprising the steps of estimating basic collision time of a first current vehicle according to driving data of the first current vehicle, a motion state of an obstacle in a target area in front of the first current vehicle and a position relation between the first current vehicle and the obstacle; a second step of estimating a collision time of a second current vehicle, including: when the second current vehicle is located in the target area, acquiring driving data of the second current vehicle and environmental data in the target area in front of the second current vehicle; estimating a basic collision time of the second current vehicle according to the first step; estimating the basic collision time of the preceding vehicle as the preceding vehicle collision time according to the first step, or estimating the preceding vehicle collision time according to the second step; and estimating the collision time of the second current vehicle according to the front vehicle collision time and the basic collision time of the second current vehicle.

    本发明提供估计车辆碰撞时间的方法和车辆碰撞预警装置,所述方法包括:估计第一当前车辆的基本碰撞时间的第一步骤,包括:根据第一当前车辆的行驶数据、第一当前车辆前方的目标区域内的障碍物的运动状态、第一当前车辆与障碍物之间的位置关系,估计第一当前车辆的基本碰撞时间;估计第二当前车辆的碰撞时间的第二步骤,包括:当第二当前车辆位于目标区域内时,获取第二当前车辆的行驶数据和其前方的目标区域内的环境数据;根据第一步骤估计第二当前车辆的基本碰撞时间;根据第一步骤估计前车的基本碰撞时间作为前车碰撞时间、或根据第二步骤估计前车碰撞时间;根据前车碰撞时间和第二当前车辆的基本碰撞时间估计第二当前车辆的碰撞时间。
