The embodiment of the invention provides a vehicle braking method and device, and relates to the technical field of active safe driving, and the method comprises the steps: calculating the longitudinal collision time based on the longitudinal position of an obstacle relative to a vehicle, and judging whether the obstacle is a collision object based on the longitudinal collision time and the transverse position of the obstacle relative to the vehicle, if yes, the detection working condition of detecting the collision object according to the sensor is determined, the target omission ratio and the target false detection ratio are determined from the sensing characteristics according to the sensing characteristics of the sensor, the working condition and the distance between the collision object and the vehicle, and whether the collision object is braked or not is determined according to the target omission ratio and the target false detection ratio. According to the embodiment of the invention, by considering the false detection rate, the missing detection rate and the error of the sensor, the false braking and the missing braking can be effectively reduced, so that the braking is more accurate and the driving is safer.

    本发明实施例提供了一种车辆制动方法和装置,涉及主动安全驾驶技术领域,该方法包括:基于障碍物的相对于车辆的纵向位置计算纵向碰撞时间,基于纵向碰撞时间以及障碍物相对于车辆的横向位置判断障碍物是否为碰撞物,若是则确定根据传感器探测碰撞物的探测工况,根据传感器的感知特性、工况和碰撞物与车辆的距离,从感知特性中确认目标漏检率和目标误检率,并根据目标漏检率和目标误检率确认是否对碰撞物进行制动。本发明实施例通过考虑传感器的误检率、漏检率和误差,能够有效地减少误制动和漏制动,从而更加准确的进行制动使得驾驶更加安全。
