The invention discloses a virtual vehicle speed calculation method and device, a vehicle-mounted terminal, a vehicle and a storage medium. The method comprises the steps that model data frames of an entity vehicle at multiple moments are acquired; a speed factor of the simulated vehicle in the simulated driving program is calculated based on the plurality of model data frames. And periodically obtaining real-time data frames of the entity vehicle. And based on the speed factor, the real-time data frame and the first virtual vehicle speed of the previous data frame, calculating the first virtual vehicle speed of the current frame of the simulation vehicle. According to the vehicle-mounted terminal disclosed by the embodiment of the invention, the virtual speed calculation model is constructed by performing self-learning on the acquired model data frame, and then the virtual speed of the current frame of the simulated vehicle is calculated by utilizing the constructed virtual speed calculation model and the real-time data frame, so that real-time accurate calculation of the virtual speed of the simulated vehicle in a simulated driving program is realized.
