The invention is applicable to the technical field of vehicle control, and provides an automatic braking method and device of a vehicle, terminal equipment and a storage medium, the method comprises the following steps: after a first signal is detected, obtaining an expected safe distance between the vehicle and a first target at a kth sampling moment, and a relative speed and a relative distance between the vehicle and the first target; according to the expected safety distance, the relative speed and the relative distance, the expected braking deceleration of the vehicle is calculated; acquiring the real deceleration of the vehicle at the kth sampling moment; determining a first target deceleration of the vehicle from the kth sampling moment to the (k + 1) th sampling moment based on the expected braking deceleration and the real deceleration at the kth sampling moment; and controlling the vehicle to brake based on the first target deceleration. The target deceleration is calculated in real time according to the sampling period, and the vehicle is decelerated according to the deceleration calculated in each sampling period, so that the vehicle braking is more accurate.
本申请适用于车辆控制技术领域,提供了一种车辆的自动制动方法、装置、终端设备及存储介质,该方法包括:在检测到第一信号后,获取第k个采样时刻车辆与第一目标的期望安全距离、车辆与第一目标的相对速度和相对距离;根据期望安全距离、相对速度和相对距离,计算车辆的期望制动减速度;获取车辆在第k个采样时刻的真实减速度;基于期望制动减速度和第k个采样时刻的真实减速度,确定车辆在所述第k个采样时刻至第k+1个采样时刻的第一目标减速度;基于第一目标减速度控制车辆进行制动。本申请按照采样周期实时计算目标减速度,车辆按照各个采样周期计算的减速度进行减速,使车辆制动更精确。
