The invention discloses a vehicle speed calculation method and device and a computer readable storage medium. The method comprises the steps: obtaining the wheel rotating speed, collected by a wheel rotating speed sensor, of at least one wheel of a vehicle, and obtaining the acceleration, collected by an acceleration sensor, of the vehicle; according to the currently obtained wheel rotating speedof at least one wheel, the current initial vehicle speed of the vehicle is obtained through calculation; calculating to obtain a current predicted vehicle speed according to the acceleration, a finalvehicle speed obtained at the previous moment and a time interval from the current moment to the previous moment; According to the current predicted vehicle speed, the initial vehicle speed is calibrated to obtain a corrected final vehicle speed. By adopting the embodiment of the invention, the problems that the vehicle speed calculation is inaccurate and the driving control performance of the vehicle is influenced in the
