The invention discloses a car following deceleration control method, device and equipment and a storage medium, and relates to the technical field of intelligent driving. The method comprises the following steps: acquiring driving data of a front vehicle and driving data of an own vehicle; according to the corresponding relation between the time interval and the predicted duration, the predicted duration corresponding to the real-time time interval of the vehicle is determined; the predicted duration represents that the motion state of the front vehicle is unchanged within the predicted duration; determining an expected distance corresponding to the speed of the preceding vehicle according to a corresponding relation between the speed and the expected distance; the expected distance represents the distance between the vehicle and the front vehicle when the vehicle is expected to decelerate to the same speed as the front vehicle; a target braking distance is determined according to the actual distance between the front vehicle and the vehicle and the expected distance, and the deceleration of the vehicle is determined according to the predicted duration and the target braking distance, so that vehicle deceleration control is carried out according to the deceleration of the vehicle; the target braking distance is inversely proportional to the deceleration of the vehicle. Different deceleration plans are adopted according to different scenes.
