The embodiment of the invention provides a cruise control method, electronic equipment, a storage medium and a program product, and relates to the field of cruise control algorithms. The actual engine torque, the actual vehicle speed and the target cruise vehicle speed of the vehicle are obtained, the required torque when the vehicle runs on the level road section at the target cruise vehicle speed in a no-load mode is calculated according to the reference whole vehicle characteristic parameters of the vehicle and serves as the static engine required torque, and the dynamic engine required torque is calculated according to the actual engine torque and the actual vehicle speed; and inputting the actual vehicle speed and the target cruise vehicle speed into a preset control algorithm to obtain an engine correction demand torque, determining an engine total demand torque according to the engine static demand torque, the engine dynamic demand torque and the engine correction demand torque, and performing torque control on an engine of the vehicle according to the engine total demand torque. The engine output torque can still be accurately provided and the vehicle speed can be stably controlled under the condition that the vehicle mass is greatly changed.
