Background technique
Current automobile cooling fan mode of speed regulation mainly contains: 1, rheostatic speed regulation; 2, motor internal speed governing; 3, PMW stepless time adjustment.The cooperation that the speed governing of cooling fan needs ECU and wire harness to control could realize, and in vehicle newly developed, the speed regulating control of fan need consider the series of factors such as performance, cost, versatility, selects the control mode of the most applicable new model.Engine water tank water temperature over-high, piston, steel wall, cylinder, bent axle equitemperature can be caused too high, and machine oil is thinning, loses lubrication; The too low meeting of engine water tank water temperature makes engine thermal conversion efficiency step-down, affects fuel economy.Engine water temperature to be remained on 60-80 degree Celsius comparatively suitable.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, a kind of fan blade rotating speed control system and controlling method thereof of automobile engine cooling fan are provided, to reach Real-time Collection engine water tank water temperature signal, the flabellum rotating speed of intelligent control cooling fan, ensures the metastable object of water temperature.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of fan blade rotating speed control system of automobile engine cooling fan, comprise the vehicular control unit (ECU) of cooling fan, controlled cooling model fan electromotor, described control system also comprises the temperature collecting cell be arranged on engine water tank, and described temperature collecting cell is connected with vehicular control unit ECU.
Described vehicular control unit ECU, for the engine water tank temperature gathered according to temperature collecting cell, controlled cooling model fan motor rotational speed, and then the flabellum rotating speed controlling fan.
Described temperature collecting cell adopts temperature transducer.
A controlling method for the fan blade rotating speed control system of automobile engine cooling fan, described method comprises the following steps:
Temperature transducer gathers engine water tank temperature, transfer signals to vehicular control unit ECU, this signal of vehicular control unit ECU process, according to the motor speed of engine water tank temperature controlled cooling model fan, and then the flabellum rotating speed of controlled cooling model fan, when engine water tank temperature raises, improve flabellum rotating speed; When engine water tank temperature reduces, reduce flabellum rotating speed.
The present invention adopts said structure and method, has the following advantages: 1, Real-time Collection engine water tank water temperature signal, the flabellum rotating speed of intelligent control cooling fan, ensures that water temperature is relatively stable; 2, optimize fan performance and reduce costs.
