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 c
