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 silicon oil clutch fan control method and device. The current engine load rate is calculated according to the engine torque, and then the silicone oil clutch bonding temperature is calculated according to the relationship between the engine load rate and the silicone oil clutch bonding temperature threshold, and the calculated silicone oil clutch is combined. The temperature is determined as the set value of the combination temperature of the silicone oil clutch. When the air temperature around the radiator is higher than the set value of the combination temperature, control or keep the combination of the silicone oil clutch. The setting value meets the heat dissipation requirements of different environments or different operating conditions, making the fan control method more accurate, and the fan cooling efficiency is high, realizing the most economical energy saving effect, and ensuring the thermal balance of the engine and the smooth development of vehicle performance evaluation.

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...
