The invention provides an electric vehicle speed calculation method and system based on a motor rotating speed and a wheel speed, electronic equipment and a computer readable storage medium. The electric automobile speed calculation method based on the motor rotating speed and the wheel speed comprises the steps that a motor rotating speed signal and a motor rotating speed signal effective bit sent by an MCU are received; four wheel speed sensor signals and wheel speed sensor signal effective bits sent by the ESC/VSA are received; after the vehicle operation mode is judged, a vehicle speed calculation strategy corresponding to the vehicle operation mode is determined, and the vehicle speed of the electric vehicle is calculated according to the vehicle speed calculation strategy. According to the embodiment of the invention, the accuracy of speed calculation of the electric vehicle can be improved.
