Embodiment 1

[0033] This embodiment provides a silicone oil clutch fan control device and a corresponding control method. Such as figure 1As shown, the silicon oil clutch fan control device of this embodiment includes a signal acquisition module, a processor, and an action execution module. The signal acquisition module includes an ambient temperature acquisition unit, an airflow temperature acquisition unit around the radiator, and an engine torque acquisition unit. The ambient temperature acquisition unit in this embodiment is an ambient temperature sensor for collecting ambient temperature, and the airflow temperature acquisition unit around the radiator is an airflow temperature sensor for collecting airflow temperature. The silicon oil clutch fan control device of this embodiment also includes a memory and a processor, and a computer program for execution by the processor is stored in the memory. The processor in this embodiment is an ARM processor, and in other implementation manner...

Embodiment 2

[0044] The device of this embodiment has the same structure as the above-mentioned embodiment 1, but the control method is different, that is: if the calculation accuracy of the set value of the silicon oil clutch joint temperature is not so high, then the relevant calculation program of the device only calculates the silicon oil once. Clutch engagement temperature, and the silicon oil clutch engagement temperature is determined as the silicon oil clutch engagement temperature setpoint, specifically, the control method of the present embodiment includes the following steps:

[0045] 1) The airflow temperature sensor collects the airflow temperature around the radiator, and the engine torque collection unit collects the engine torque T0, and sends the collected airflow temperature around the radiator and engine torque T0 to the ARM processor.

[0046] 2) The ARM processor calculates the current engine load rate based on the engine torque T0 In order to calculate the engine loa...

Abstract

The invention provides a silicone oil clutch fan control method and device. The method comprises the steps that the current engine load rate is calculated according to the engine torque; then, the silicone oil clutch engagement temperature is calculated according to the relation between the engine load rate and a silicone oil clutch engagement temperature threshold value; the calculated silicone oil clutch engagement temperature is determined as a silicone oil clutch engagement temperature set value; and when the cooler surrounding airflow temperature is higher than the engagement temperatureset value, a silicone oil clutch is controlled to perform engagement or kept performing engagement, otherwise, the silicone oil clutch is controlled to perform disengagement or kept performing disengagement. By adjusting and calculating the silicone oil clutch engagement temperature set value in real time, the heat dissipation requirements of different environments or different operation conditions are met, the fan control mode is more accurate, the fan cooling efficiency is high, the most economical energy-saving effect is achieved, and the heat balance of an engine and the smooth vehicle performance evaluation work are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile cooling fan control, and in particular relates to a silicon oil clutch fan control method and device. Background technique [0002] During the driving process of the car, due to the change of environmental conditions and operating conditions, the thermal condition of the engine is also changing. In order to ensure that the engine is in the best working condition, the cooling intensity of the engine must be adjusted at all times. For example, in the hot summer, when the temperature of the engine coolant is high, the fan should rotate at high speed to increase the cooling air volume; while in the cold winter, the temperature of the coolant is low, or there is a strong headwind blowing through the radiator when the car is driving at high speed. At this time, it becomes meaningless for the fan to continue to work at high speed. Similarly, when the engine is climbing, rapid acceleration and other w...
