Abstract

The invention relates to a vehicle cooling system control method and controller and a vehicle. The vehicle cooling system control method comprises the steps that the target heat dissipating capacity of a cooling system is calculated, the target air volume of fans in the cooling system is calculated according to the target heat dissipating capacity, corresponding fan rotating speeds ni when the fan starting number ranges from 1 to m is obtained according to the target air volume and the number m of the fans, corresponding fan noise Si is obtained according to the fan rotating speeds ni, the fan starting number i1 and the fan rotating speed ni1, corresponding to a first minimum noise value, is obtained according to the first minimum noise value in the fan noise Si, and the fan starting number i1 and the fan rotating speed ni1 are executed according to the fact that the outlet water temperature of the cooling system is within the set range. The starting number and the rotating speed of the fans are controlled through real-time calculation of the target heat dissipating capacity and the target air volume, normal work of the cooling system is met, and the noise of the cooling system is reduced through selection of the fan starting number and rotating speed corresponding to the minimum noise.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a vehicle cooling system control method, a controller and a vehicle. Background technique [0002] This section provides merely background information related to the present disclosure and is not necessarily prior art. [0003] As the power source of the vehicle, the performance of the engine is related to the safety and quality of the vehicle. The temperature of the engine is an important parameter in the working process of the engine. Therefore, the vehicle usually uses the cooling system to control and adjust the temperature of the engine. [0004] Existing cooling systems usually include radiators, fans, water pumps and thermostats. During the engine cooling cycle, the engine coolant enters the engine body after being pressurized by the water pump. The radiator returns to the water pump after being cooled by the fan, and the cooling of the engine is completed...
