The invention relates to a vehicle speed control method and device, a medium, equipment and a vehicle. The method comprises the steps of obtaining real-time state data of the vehicle; the real-time state data comprises real-time estimated mass, current vehicle speed, expected vehicle speed and road condition information; the road condition information comprises a current road gradient, a road adhesion coefficient and a road rolling resistance coefficient; determining a target torque based on the real-time state data; the target torque is used for adjusting the vehicle from the current vehicle speed to the expected vehicle speed. According to the technical scheme, the target torque corresponding to vehicle speed control is determined by combining the real-time estimated mass, the current vehicle speed, the expected vehicle speed and the road condition information of the vehicle, such as the real-time state data of the current road slope, the road adhesion coefficient and the road rolling resistance coefficient; the vehicle speed can be timely and accurately controlled according to different vehicle conditions and road conditions, namely, the response speed is high, and the following performance is good.
