Abstract

The invention belongs to the technical field of vehicle engines, and particularly relates to a control method, device and system for an electric fan in a vehicle. The control method for the electric fan in the vehicle includes the following steps of obtaining the current state of the electric fan, and controlling a heater on the electric fan to perform heating when the current rotating speed of the electric fan is lower than a preset rotating speed. In the control method for the electric fan in the vehicle, when the current rotating speed of the electric fan is lower than the preset rotating speed, the heater on the electric fan is controlled to perform heating; when the current rotating speed of the electric fan is lower than the preset rotating speed, a logical judgment is made and corresponding actions are taken, so that the faults of the electric fan can be solved through a logical control unit of an engine, no shutdown overhaul is needed, and the electric fan can be prevented fromburning down.

Description

technical field [0001] The invention belongs to the technical field of vehicle engines, and in particular relates to a control method, a control device and a control system for an electronic fan in a vehicle. Background technique [0002] The radiator and fan of the passenger car are arranged on the roof. Ice and snow in winter will cause the fan to get stuck or freeze. Since the user is not easy to detect, it is very easy to cause the fan motor to block and be burned, which in turn will cause the fuel cell engine to limit power or shut down. Contents of the invention [0003] The purpose of the present invention is to at least solve the problem that the existing ice and snow in winter will cause the fan to be stuck or frozen, and then cause the fuel cell engine to limit power or shut down. This purpose is achieved through the following technical solutions: [0004] The first aspect of the present invention proposes a method for controlling an electronic fan in a vehicle,...
