The invention discloses a wheel slip rate determination method, device, equipment and medium, and the method comprises the steps: determining the wheel track radius corresponding to the wheel moving track of each wheel of a target vehicle according to the corresponding driving moving coordinate of the target vehicle in a target time period; according to the vehicle yaw angle corresponding to the target vehicle in the target time period and the wheel track radius corresponding to each wheel, determining the wheel track length of each wheel; according to the wheel track length corresponding to each wheel in the target time period, the tire radius of each wheel and the steering state of the target vehicle, the theoretical rotating speed of each wheel is determined; and according to the theoretical rotating speed corresponding to each wheel and the measured actual rotating speed corresponding to each wheel, the actual slip rate corresponding to each wheel is determined. According to the invention, the accuracy of the wheel slip rate is improved, the probability of wrong work of vehicle driving anti-slip and braking anti-lock can be reduced, and the driving safety of the vehicle is improved.
