A vehicle speed calculation method, system, device, and storage medium consistent with the embodiments of the present disclosure are provided. The method includes obtaining an echo signal and generating detection data according to the echo signal, determining a moving speed of a stationary object, that is near the vehicle relative and stationary relative to a ground, to the vehicle according to the detection data, determining a vehicle speed according to the moving speed of the stationary object relative to the vehicle. In the embodiment of the present disclosure, the echo signal is obtained and the detection data is generated according to the echo signal. The moving speed of the stationary object, that is stationary relative to the ground and is around the vehicle, relative to the vehicle is determined according to the detection data. The vehicle speed is determined according to the moving speed of the stationary object relative to the vehicle. That is, the vehicle speed can be determined by processing the echo signal. There is no need to obtain the vehicle speed from a CAN bus, which avoids a transmission delay of the CAN bus and enables to obtain the vehicle speed in real time, thereby improving a real-time nature of obtaining of the vehicle speed and avoiding an impact on performance of the radar.
