The invention provides a speed control method, device and equipment and a computer readable storage medium, and the method comprises the steps: obtaining a car following model under the condition that the safety distance between a car and a front car is satisfied, and the car following model comprises a motion equation describing a plurality of longitudinal tracks, the motion equation describes the relation between the displacement of the self-vehicle in the longitudinal track and the time; solving the car following model to obtain a solving result; and controlling the speed of the vehicle based on the solving result. Wherein the multiple sections of longitudinal tracks comprise a first section of longitudinal track, a second section of longitudinal track, a third section of longitudinal track and a fourth section of longitudinal track; the acceleration change rate of the first section of longitudinal track is equal to that of the third section of longitudinal track, and the acceleration of the second section of longitudinal track and the acceleration of the fourth section of longitudinal track are constant values. According to the invention, the controllability and stability of car following driving can be ensured.
