Problems solved by technology

If the water temperature of the engine water tank is too high, the temperature of the piston, steel wall, cylinder, crankshaft, etc. will be too high, and the engine oil will become thinner and lose its lubricating effect; if the water temperature of the engine water tank is too low, the heat conversion efficiency of the engine will decrease, which will affect fuel economy.

Embodiment Construction

[0015] like Figure 1 ~ Figure 2 Shown is a blade speed control system for a cooling fan of an automobile engine, comprising a cooling fan and a vehicle-mounted control unit ECU for controlling the motor of the cooling fan, and the control system also includes a temperature acquisition unit 1 arranged on the engine water tank, the temperature acquisition unit 1 and the vehicle-mounted Control unit ECU connection. The vehicle-mounted control unit ECU is used to control the cooling fan motor speed according to the temperature of the engine water tank collected by the temperature collection unit 1, and then control the fan blade speed of the fan. The temperature acquisition unit 1 adopts a temperature sensor.

[0016] A control method for a fan blade speed control system of an automobile engine cooling fan, the method includes the following steps:

[0017] The temperature sensor collects the temperature of the engine water tank and transmits the signal to the on-board control u...

Abstract

The invention discloses an automobile engine cooling fan blade rotating speed control system which comprises a cooling fan and an electronic control unit (ECU) for controlling a cooling fan motor. The control system further comprises a temperature collection unit arranged on an engine water tank. The temperature collection unit is connected with the ECU. By the adoption of the structure and method, the automobile engine cooling fan blade rotating speed control system has the advantages that the water temperature signals of the engine water tank are collected in real time, the cooling fan blade rotating speed is intelligently controlled, it is ensured that water temperature is relatively stable, and the fan performance is optimized, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile engine cooling fans, in particular to a fan blade rotational speed control system and a control method thereof of an automobile engine cooling fan. Background technique [0002] At present, the speed regulation methods of automobile cooling fans mainly include: 1. Resistance speed regulation; 2. Internal speed regulation of the motor; 3. PMW stepless speed regulation. The speed regulation of the cooling fan requires the cooperation of the ECU and the wiring harness control. In the newly developed model, the fan speed control needs to comprehensively consider a series of factors such as performance, cost, and versatility, and choose the most suitable control method for the new model. If the water temperature of the engine water tank is too high, the temperature of the piston, steel wall, cylinder, crankshaft, etc. will be too high, and the engine oil will become thinner and lose its lubricating ...
