The invention discloses a rolling radius compensation method and device based on the yaw rate and a computer readable storage medium, and the method comprises the following steps: obtaining the current motion state of a vehicle when the vehicle makes a turning motion, and judging whether the current motion state of the vehicle meets a preset condition or not; if the current motion state of the vehicle meets the preset condition, acquiring vehicle body parameters of the vehicle, and calculating the yaw rate of the vehicle by utilizing the current motion state of the vehicle and the vehicle bodyparameters according to a vehicle yaw rate calculation method; and compensating the tire rolling radius of the vehicle by utilizing the yaw rate of the vehicle. According to the method, the problem that in the prior art, tire rolling radius recognition is inaccurate when the vehicle turns is solved, compensation for the tire rolling radius when the vehicle turns is achieved by calculating the yawrate of the vehicle, and the tire rolling radius recognition accuracy is improved.
