The invention relates to the technical field of vehicle control, and discloses a rear wheel steering control method, device and equipment and a computer readable storage medium. The method comprises the steps that the value of a proportionality coefficient is determined according to the suspension height of a vehicle at a preset moment; wherein the proportionality coefficient is used for representing an incidence relation between a rear steering gear lead screw displacement value and a rear wheel steering angle value of the vehicle; and determining a rear wheel steering angle value of the vehicle at the preset moment according to the value of the proportionality coefficient and a rear steering gear lead screw displacement value of the vehicle at the preset moment, and performing steering control on rear wheels of the vehicle according to the rear wheel steering angle value at the preset moment. According to the technical scheme, different proportional relations can be selected based on different suspension heights, and therefore accurate estimation of the rear wheel turning angle is achieved.
