The invention discloses an adaptive cruise vehicle deceleration method, device and equipment and a storage medium. The method comprises the steps that a vehicle speed difference is obtained according to the difference value between the set vehicle speed of a vehicle and the actual vehicle speed of the vehicle, and whether the vehicle needs to be decelerated or not is judged according to the vehicle speed difference; if the vehicle needs to be decelerated, initial deceleration is determined according to the vehicle speed difference, and an expected vehicle speed difference threshold value is determined based on the initial deceleration, a preset deceleration threshold value and a preset deceleration change rate; if the vehicle speed difference is larger than the expected vehicle speed difference threshold value, the corresponding expected deceleration change rate is determined based on the vehicle speed difference and the initial deceleration; according to the sum of the integral of the expected deceleration change rate and the initial deceleration, real-time target deceleration is obtained, and deceleration is conducted according to the real-time target deceleration. And speed following can be responded in time, and the deceleration comfort is improved.

    本申请公开了一种自适应巡航车辆减速方法、装置、设备及存储介质。涉及辅助驾驶技术领域,该方法包括:根据车辆的设定车速与车辆的实际车速的差值得到车速差,并根据所述车速差判断所述车辆是否需要减速;若所述车辆需要减速,根据所述车速差确定出初始减速度,基于所述初始减速度、预设的减速度阈值以及预设减速度变化率,确定出期望车速差阈值;若所述车速差大于所述期望车速差阈值,则基于所述车速差和所述初始减速度确定对应的期望减速度变化率;根据所述期望减速度变化率的积分与所述初始减速度的和,得到实时目标减速度,并根据所述实时目标减速度进行减速。可以及时响应速度跟随并提高减速的舒适性。
