The invention provides an automatic emergency braking method and system, a vehicle-mounted terminal and a medium. The method comprises the steps that when a vehicle is in an automatic emergency braking state, the vehicle speed, the vehicle body acceleration and the vehicle dynamic acceleration are obtained, and when it is detected that a target object exists in a front preset range, the radial distance between the vehicle and the target object and the height and speed of the target object are obtained; when the vehicle is located on the ramp, the radial distance is corrected based on the height of the target object, the vehicle body acceleration and the vehicle dynamic acceleration; and according to the corrected radial distance, the vehicle speed and the speed of the target object, collision time is predicted, and emergency braking is conducted according to the collision time. The measurement accuracy of the radial distance is improved, and the driving safety is effectively improved.

    本发明提供一种自动紧急制动的方法、系统、车载终端及介质。方法包括:在车辆处于自动紧急制动的状态下,获取车辆速度、车身加速度和车辆动态加速度,并在检测到前方预设范围内存在目标物体时,获取车辆与目标物体的径向距离、目标物体的高度和速度;根据车身加速度确定车辆的位置:在车辆位于坡道时,基于目标物体的高度、车身加速度和车辆动态加速度修正径向距离;根据修正后径向距离、车辆速度和目标物体的速度,预测碰撞时间,并根据碰撞时间进行紧急制动。提升了径向距离的测量精确度,有效提升了行车安全。
