Abstract

The invention provides a fan control method and system for a vehicle and the vehicle, and relates to the field of vehicle cooling. The method comprises the following steps that firstly, after the vehicle is powered on, the water temperature of each cooling loop in the vehicle and the temperature of each part in each cooling loop are acquired in real time; then when the water temperature of the cooling loops is higher than first preset temperature, first output needs, corresponding to each fan, of the water temperature of the cooling loops is found from a preset storage module, and when temperature of the parts is higher than second preset temperature, second output needs, corresponding to each fan, of the temperature of the parts is found from preset storage module ; and finally, the maximum value in all the first output needs and the second output needs is selected to control each fan, so that the cooling needs of all the cooling loops are met at the same time. The cooling needs of each cooling loop and each part in each cooling loop in the vehicle can be comprehensively considered, and the cooling needs of all the cooling loops can be met at the same time.

Description

technical field [0001] The invention relates to the field of vehicle cooling, in particular to a fan control method, control system and vehicle for vehicles. Background technique [0002] At present, with the popularization of new energy vehicles in major and medium-sized cities in China, new energy vehicles with automatic power-renewing capabilities - extended-range vehicles have gradually entered the public's field of vision. Extended-range vehicles are equipped with on-board power generation on the basis of original pure electric vehicles System - range extender (engine plus generator). Compared with ordinary pure electric vehicles, range-extended electric vehicles not only have the advantages of pure electric vehicles, but also can solve the anxiety of pure electric vehicle cruising range and meet the needs of long-distance driving. The range-extended power vehicle includes two major energy supply systems, the range extender and the power battery. The range extender (eng...
