As shown in Figure 1, the invention provides a kind of control system of engine electric-controlled fan, comprising:
1. engine body cyclic water channel, be 2. engine water temperature sensor, for monitoring engine water temperature, 3. for Engine ECU, to be arranged on engine body, 4. for communication CAN line, be 5. hydrodynamic retarder ECU, to be arranged on hydrodynamic retarder body, to be 6. hydrodynamic retarder cooling-water temperature sensor, for monitoring hydrodynamic retarder water temperature, being 7. hydrodynamic retarder bulk circulation water channel; 8. be thermostat, for the large and small cycles of controlled circulation water, whether enter cooling water tank, 9. for cooling water tank, for water temperature heat radiation, 10. electrical control electric fan, be contained on engine crankshaft.
As seen from Figure 1, engine body cyclic water channel, hydrodynamic retarder bulk circulation water channel and cooling water tank three form water circulator, the water outlet of engine body cyclic water channel can enter hydrodynamic retarder bulk circulation water channel, when the water temperature over-high of hydrodynamic retarder, thermostat is entered by hydrodynamic retarder outlet pipe, when thermostat judges output water temperature higher than open temp, then cooling water tank is put in the water outlet of hydrodynamic retarder bulk circulation water channel, if when thermostat judges output water temperature lower than open temp, then the water outlet of hydrodynamic retarder directly enters engine body cyclic water channel, recycle.
After the hot water of cooling water tank is dispelled the heat by electrical control electric fan, then cooled water enters to engine body cyclic water channel by the radiator drain of cooling water tank, and then enter hydrodynamic retarder bulk circulation water channel, thus be reached for the object of engine body cyclic water channel and the cooling of hydrodynamic retarder bulk circulation water channel.
As shown in Figure 2, the invention provides a kind of controlling method of engine electric-controlled fan, comprising:
Step S101: receive the message carrying negative torque that hydrodynamic retarder ECU sends, described message is hydrodynamic retarder ECU detecting that the water temperature of hydrodynamic retarder bulk circulation water channel sends when being greater than preset temperature;
This method is applied in Engine ECU, whether the water temperature that Engine ECU self can detect engine body cyclic water channel exceedes setting temperature, electrical control electric fan can be controlled with certain rotational speed when exceeding setting temperature, when there being other water temperature controlled conditionss, Engine ECU also can calculate all the other rotating speeds of electrical control electric fan by other water temperature controlled conditions.
In addition, motor also can receive the message carrying negative torque that hydrodynamic retarder ECU sends, and carries out calculating first rotation speed of the fan corresponding with negative torque according to negative torque.The present invention adopts the CAN between Engine ECU and hydrodynamic retarder ECU to carry out message transmissions, so neither need to increase independent wire harness between Engine ECU and hydrodynamic retarder ECU, the structural relation of motor and hydrodynamic retarder ECU can not be changed again, simple and convenient.
Step S102: calculate first rotation speed of the fan corresponding with described negative torque;
The method calculating the first corresponding rotation speed of the fan according to negative torque has multiple, and the present embodiment provides following several mode:
The first: is when the water temperature of hydrodynamic retarder bulk circulation water channel is greater than preset temperature, just the negative torque of a fixed numbers is started to Engine ECU, Engine ECU calculates an electrical control electric fan rotating speed, using this electrical control electric fan rotating speed as the first rotation speed of the fan according to fixing negative torque.
The second: when the water temperature of hydrodynamic retarder bulk circulation water channel is greater than preset temperature, the negative torque of different size can be sent to Engine ECU according to the size of hydrodynamic retarder water temperature, motor calculates the electrical control electric fan rotating speed of different size according to negative torque, be understandable that, the water temperature of hydrodynamic retarder bulk circulation water channel is higher, and the rotating speed of the electrical control electric fan calculated is larger.
The third: is when the water temperature of hydrodynamic retarder bulk circulation water channel is greater than preset temperature, to engine start negative torque, (negative torque can be fixed value, also can change along with water temperature size), when described negative torque is less than predetermined torque, state of a control position is 1; Rotation speed of the fan will be preset as described first rotation speed of the fan when described mode bit is 1.
The present embodiment provide only three kinds of modes of calculating first electrical control electric fan rotating speed, certainly the first rotation speed of the fan other modes can also be adopted calculate the first rotation speed of the fan corresponding with negative torque, as long as can be reached for the object that hydrodynamic retarder bulk circulation water channel carries out dispelling the heat.
Step S103: choose maximum rotation speed of the fan in described first rotation speed of the fan and all the other rotation speeds of the fan, all the other rotation speeds of the fan described are at least one rotation speed of the fan utilizing other water temperature conditions to calculate;
Because motor and hydrodynamic retarder share a cooling water tank, and engine body cyclic water channel is communicated with hydrodynamic retarder bulk circulation water channel, dispel the heat so control electrical control electric fan to cooling water tank, can be able to be again the cooling of hydrodynamic retarder bulk circulation water channel to the cooling of engine body cyclic water channel simultaneously.In order to meet the dual requirements of engine body cyclic water channel and hydrodynamic retarder bulk circulation water channel, and the demand of other water temperature controlled conditionss, so first rotation speed of the fan of hydrodynamic retarder ECU, the rotation speed of the fan of Engine ECU, and select maximum rotation speed of the fan in all the other rotation speeds of the fan, utilize maximum rotation speed of the fan to control electrical control electric fan and run.
Electrical control electric fan with the running of maximum rotation speed of the fan, thus makes cooling water tank dispel the heat with maximum heat dissipation rate, thus meets the double-radiation function demand of hydrodynamic retarder ECU and Engine ECU.
Step S104: control described electrical control electric fan according to described maximum rotation speed of the fan running.
There are between Engine ECU and electrical control electric fan two relays, two relays adopt the first wind speed threshold value and the second wind speed threshold value to control, a Control electrical control electric fan middling speed running, another Control electrical control electric fan runs up, Engine ECU judges after obtaining maximum rotation speed of the fan that maximum rotation speed of the fan and the first wind speed threshold value and the second wind speed threshold value contrast, when described maximum rotation speed of the fan is greater than the first wind speed threshold value, then closed first relay corresponding with described first wind speed threshold value; When described maximum rotation speed of the fan is greater than the second wind speed threshold value, then closed second relay corresponding with described second wind speed threshold value.
After corresponding relay closes, electrical control electric fan is according to the rotation speed operation of correspondence, then the first relay closes is only controlled when maximum rotation speed of the fan is only greater than the first wind speed threshold value, control the running of electrical control electric fan middling speed, when maximum rotation speed of the fan is greater than the second wind speed threshold value, first relay and the second relay all closed, control electrical control electric fan runs up, thus as early as possible for cooling water tank dispels the heat.

When the water temperature of hydrodynamic retarder is lower than another water temperature set, then stop sending message to Engine ECU.
Step S202: when described hydrodynamic retarder water temperature is greater than preset temperature, sends the message carrying negative torque to Engine ECU.
