The invention discloses a wheel speed calculation method, device and system and a storage medium, which are used for ensuring that a vehicle driving anti-skid control function is normal when a wheel speed sensor of a tire fails. The method comprises the steps that when it is detected that a wheel speed sensor corresponding to a first tire of a vehicle fails, the driving state of the vehicle is obtained; when the driving state of the vehicle represents that the vehicle is in the starting state, the acceleration integral speed is determined, and the acceleration integral speed is the integral speed obtained by conducting integration according to the longitudinal acceleration of the vehicle; substituting the acceleration integral speed into a first preset formula for calculation, and taking a calculation result of the first preset formula as a first calculation value of the current wheel speed of the first tire; and determining the first calculated value of the current wheel speed of the first tire as the final value of the current wheel speed of the first tire. By adopting the scheme provided by the invention, when the wheel speed sensor of the first tire fails, the normal driving anti-skid control function of the vehicle is ensured.
