The invention provides a cruise vehicle speed control method and device, equipment, a storage medium and a program product, and relates to the technical field of vehicle intelligent driving assistance. The method comprises the following steps: acquiring jth to ith state information of a current vehicle; according to the road adhesion coefficient utilization rate corresponding to the weight of the current vehicle and the ith road adhesion coefficient estimated in real time, the ith maximum braking acceleration of the current vehicle is determined; calculating the ith minimum braking distance of the current vehicle according to the ith maximum braking acceleration and the ith actual vehicle speed of the current vehicle; and in the ith vehicle speed control period, the vehicle speed of the current vehicle is controlled according to the ith minimum braking distance and the state information. According to the method, the minimum braking distance is dynamically adjusted by applying the road adhesion coefficient utilization rate under different vehicle weights, the accuracy of the determined minimum braking distance is improved, and then the driving safety of the heavy commercial vehicle is improved.
