Abstract: A method and a system for controlling cooling of a vehicle, and a vehicle are provided in the present disclosure. In the present disclosure, a maximum value among cooling demand values of cooling objects is used to control a servo component in a cooling system to operate according to an execution opening determined by a preset corresponding relation, so that operating states of the servo components may be correlated and may be comprehensively controlled, so as to prevent the control system from oscillating and improve control stability, thus solving a problem that periodic oscillation of the operating states of the servo components is easily caused and service life of the servo components is affected in existing control modes of the cooling system of the vehicle.

Abstract: The present disclosure provides a method for dissipating heat from a vehicle, a storage medium, and a vehicle. The method includes the following steps: determining a target opening angle of an active air-intake grille based on a current vehicle-speed and a current heat-dissipation demand of the vehicle while the vehicle is in a driving state; determining a residual heat-dissipation demand of the vehicle based on the current heat-dissipation demand and a heat-dissipation demand that can be provided by the target opening angle; determining, according to the residual heat-dissipation demand, the target speed gear required for the cooling fan of the vehicle to provide the residual heat-dissipation demand; and adjusting an opening angle of the active air-intake grille of the vehicle to the target opening angle and a speed gear of the cooling fan to the target speed gear, to perform a heat dissipation for the vehicle.
