The invention discloses a vehicle heat dissipation system, a control method and a computer program product in the technical field of power system heat dissipation, and aims to solve the problem that in the prior art, the heat dissipation requirement under the low-output working condition of an engine is difficult to meet in a self-adaptive mode. The cooling device comprises a variable hydraulic pump and a fan, the fan is used for cooling the radiator, and the variable hydraulic pump is in transmission connection with a transmission shaft for driving an axle; the controller adjusts the opening degree of the variable hydraulic pump according to the backflow temperature of the radiator; the variable hydraulic pump takes power from the transmission shaft to ensure that the heat dissipation capacity of the radiator is roughly matched with the heat dissipation requirement of the vehicle, and the difference between the heat dissipation capacity of the radiator and the heat dissipation requirement of the vehicle is further reduced on the basis that the heat dissipation capacity of the radiator is roughly matched with the heat dissipation requirement of the vehicle based on the backflow temperature of the radiator. And effective heat dissipation can be carried out on the working conditions, such as downhill and deceleration, that the engine output power is low but the heat dissipation requirement is still high.
