1. A method for dissipating heat from a vehicle, comprising:
obtaining a current vehicle-speed and a current heat-dissipation demand of the vehicle while the vehicle is in a driving state;
determining, according to the current vehicle-speed and the current heat-dissipation demand, a target opening angle of an active air-intake grille matching both the current vehicle-speed and the current heat-dissipation demand;
determining a residual heat-dissipation demand of the vehicle based on the current heat-dissipation demand and a heat-dissipation demand that the target opening angle can provide;
determining, according to the residual heat-dissipation demand, a target speed gear required for a cooling fan of the vehicle to provide the residual heat-dissipation demand;
adjusting an opening angle of the active air-intake grille to the target opening angle and adjusting a speed gear of the cooling fan to the target speed gear, to perform a heat dissipation for the vehicle, and
controlling the active air-intake grille to be fully opened in an event that the cooling fan needs to be operated and the cooling fan malfunctions.
