The invention is suitable for the technical field of vehicle braking, and provides a method and device for controlling automatic braking of a vehicle, terminal equipment and a storage medium. The method comprises the steps that when it is detected that an obstacle exists in front of the vehicle, the actual distance between the vehicle and a target obstacle and the actual speed of the target obstacle are calculated; calculating the expected deceleration required by the vehicle at the current time; and if the absolute value of the expected deceleration is larger than or equal to the calibrated deceleration corresponding to the current vehicle speed, an automatic emergency braking system is started. Whether automatic emergency braking is needed or not is judged according to the calibrated deceleration corresponding to the current vehicle speed and the expected deceleration at the current time, and the calibrated deceleration corresponding to the current vehicle speed and the expected deceleration at the current time both change along with the state change of the vehicle. According to the method, the automatic emergency braking is determined to be started according to the real-time state of the vehicle, so that the starting of the automatic emergency braking is more accurate.
本申请适用于车辆制动技术领域,提供了一种控制车辆自动制动的方法、装置、终端设备及存储介质,该方法包括:在检测到车辆的前方存在障碍物时,通过车辆与目标障碍物的实际距离和目标障碍物的实际速度,计算当前时间车辆需要的期望减速度;若期望减速度的绝对值大于或等于当前车速对应的标定减速度,则启动自动紧急制动系统。本申请根据当前车速对应的标定减速度和当前时间的期望减速度判断是否需要自动紧急制动,当前车速对应的标定减速度和当前时间的期望减速度均是随着车辆的状态变化而变的,因此,本申请是根据车辆的实时状态确定启动自动紧急制动的,使自动紧急制动的启动更准确。
