Abstract

The invention relates to an electronically controlled silicon oil fan, in particular to an electronically controlled silicon oil fan control method and a controller. The controller is arranged in an engine compartment, and a circuit board is arranged between an upper cover plate and a lower cover plate. Electrical elements arranged on the circuit board constitute a control circuit, and the controlcircuit includes a CAN acquisition circuit, an MCU integrated circuit, a power supply circuit and a PWM control circuit. The operating parameters in an ECU of a vehicle are read by the CAN acquisition circuit and sent to the MCU integrated circuit; a fan control signal is formed through the logical judgment of the collected operating parameters by the MCU integrated circuit and sent to the PWM control circuit; the PWM control circuit converts the received fan control signal into a PWM signal to be used for controlling the rotation speed of a fan; and the actual rotation speed value of the fanis dynamically controlled by reading the collected real-time operating parameters of the vehicle.

Description

technical field [0001] The invention relates to an electronically controlled silicon oil fan, in particular to a control method and a controller for an electronically controlled silicon oil fan. Background technique [0002] During the driving process of the car, as the operating environment and working conditions change, the thermal state of the engine is also constantly changing. In order to ensure normal driving, it is necessary to adjust the thermal state of the engine in real time. For example, in hot summer, when the engine works at low speed and heavy load for a long time, the temperature of the engine is high. At this time, we should actively reduce its temperature; When the temperature of the engine is low, we should increase its temperature at this time. [0003] At present, the heat dissipation of the engine in commercial vehicles is mainly carried out by silicon oil fans. Silicon oil fans use silicone oil as a medium to transmit torque and then drive the fan to ...
