Abstract

The present invention provides a method for controlling a cooling system, comprising: receiving an input cooling rate Vx; The corresponding electronic fan opening value Kf and electronic water pump opening value Kb; control the operation of the cooling system electronic water pump and electronic fan according to the electronic fan opening value Kf and the electronic water pump opening value Kb. The cooling system control method provided by the present invention realizes that according to the input cooling rate Vx, the corresponding electronic fan opening value Kf and electronic water pump opening value Kb are obtained, and then according to the electronic fan opening value Kf, electronic water pump opening value The purpose of the value Kb is to accurately control the operation of the electronic fan and the electronic water pump, and accurately match the cooling effect required by the system.

Description

technical field [0001] The invention belongs to the technical field of cooling systems, and in particular relates to a cooling system, a control method and a vehicle. Background technique [0002] With the continuous development of technology, the application of electronic fans and electronic water pumps in cooling systems is becoming more and more common. However, the inventors found that in the cooling system of the prior art, the control strategy of the electronic fan and the electronic water pump cannot accurately match the cooling effect required by the system. Contents of the invention [0003] In order to solve the deficiencies in the prior art, an embodiment of the present invention provides a cooling system control method, including the following steps: [0004] Receive the input cooling rate Vx; [0005] According to the corresponding relationship between the preset cooling rate and the opening value of the electronic fan and the opening value of the electronic...
