The invention discloses a vehicle speed control method, device and equipment, a medium and a product. The method comprises the following steps: determining each current candidate planning state of a current planning position point in a slope road section based on a current cruise control speed; the candidate planning state comprises a candidate planning speed and a candidate planning gear; determining a current target planning state for the current planning position point based on the target planning speed of the previous planning position point, the gradient of the gradient road section, the current candidate planning state, the current battery state and a preset distance step length; and based on the current target planning state, the current motor demand torque is determined for the current planning position point, and the current motor demand torque is used for controlling the speed of the vehicle. According to the technical scheme, the speed of the vehicle running on the slope road section in the cruise control state is re-planned and controlled, and the energy consumption of the vehicle is reduced.
