Embodiment
Below, describe embodiments of the invention with reference to the accompanying drawings in detail.
Fig. 1 is the skeleton diagram of the vehicle motor cooling system of the preferred embodiments of the present invention.With reference to this accompanying drawing as can be seen, vehicle motor cooling system of the present invention is made of first circulating path and second circulating path, first circulating path is: the cooling water of motor pumps the heat that cylinder block by motor 2 and cylinder head absorb motor by water pump 1, by heater fuse 3 and after making vehicle warm, flow into water pump 1 once more then; Second circulating path is: the cooling water of motor pumps the heat that cylinder block by motor 2 and cylinder head absorb motor by water pump 1, emit after the heat through radiator 4 then, cylinder block by water pump 1 inflow engine 2 again cools off motor via cyclic process so.
At this moment, flow of cooling water is often arranged in first circulating path, so but because the very little influence for coolant water temperature of circuit cooling water inflow is very little.On the other hand, the cooling water inflow that utilizes electronic valve 10,11,12 can regulate to flow by second circulating path.
Have cooling fan arrangement 5 on radiator 4, work is by sending the heat exchange performance that air improves radiator 4 when coolant water temperature is crossed uniform temperature.In addition, also have outlet temperature meter 6, but the coolant water temperature output temperature testing signal of the outlet of detection of engine 2.
Meanwhile, also have the control section 20 of control electronic valve device 10,11,12, the electronic valve device comprises valve 10, motor 11 and motoring part 12.
Valve 10 is according to the power that is applied, and regulates the valve of switching amount form, and motor 11 produces power, offers valve 10.
For example, when not detecting rotational position with described motor, can use according to input signal, rotor moves to the stepping motor of tram.
Motoring part 12 with the phase adjust signal that is applied from control section 20, is applied to power supply on the motor 11 drive motor.
Control section 20 is counted checkout value according to the throttle valve position checkout value and the engine revolution of counting sensor (not illustrating among the figure) input from the throttle valve position sensor (not illustrating the figure) and the engine revolution of motor 2, judges the operating load of motor 2.In addition, again according to temperature detection signal, judge the coolant water temperature of the outlet side of motor 2 from 6 inputs of outlet temperature meter.
Control section 20, according to the circulating path of the outlet coolant water temperature of operating load of being judged and motor 2 decision cooling water and the switching amount of valve, corresponding to this, the control signal that produces open and close valve 10 also is applied on the motoring part 12.
For example, the control signal that produces from control section 20 also can be pulse width modulating signal (Pulse Width Modulation; " PWM ").
Below, the working procedure of the present invention of described structure is described with reference to accompanying drawing.
At first, control section 20 calculates and counts throttle valve position checkout value and the engine revolution that sensor (not illustrating among the figure) imports from the throttle valve position sensor (not illustrating the figure) of motor 2 and engine revolution and count the operating load value S10 that checkout value is obtained motor 2; Whether the operating load of judging present engine 2 is predefined full load operation state or predefined middle load running state S20.
If the judged result in step S20 is the full load operation state, then control section 20 decision target temperatures be the first setting temperature T1 (for example, about 90 ℃), go out the coolant water temperature of the outlet side of present engine 2 according to input, with current coolant water temperature and first setting temperature T1 comparison S30 from outlet temperature meter 6 input.
If the comparative result in described step S20 is that current coolant water temperature is below the first setting temperature T1, then for keeping cooling fan arrangement 5 simultaneously at off state S40 because coolant water temperature hangs down the closed condition that does not need cooling water circuit state, control section 20 to keep valve 10.
If the comparative result among the described step S30 is that current coolant water temperature is than the first setting temperature T1 height, then control signal that makes valve 10 open predefined valve switching amount A of control section 20 generations is applied on the motoring part 12, with driven at low speed cooling fan arrangement 5S50, proceed to the PI control step S80 of following valve switching amount simultaneously.
Make motor 11 work according to the control signal motoring part of sending from control section 20 12, valve 10 is opened a switching amount A like this, the cooling water of opening motor of valve 10 extrudes and passes through in turn the cylinder block of motor 2 and the heat that cylinder head absorbs motor from water pump 1, after emitting heat by the outlet discharge of cylinder head through radiator 4 again, by the cylinder block of water pump 1 inflow engine 2, can play cooling action once more through this cyclic process cooling system.
As a reference, valve switching amount A is set at the switching amount B little value of circuit cooling water inflow than aftermentioned valve.
On the other hand, if the judged result among the step S20 is the operating load state of motor is not the full load operation state, but middle load running state, then control section 20 decision target temperatures be second setting temperature T2 (for example, about 110 ℃), go out the coolant water temperature of the outlet side of present engine 2 according to input, with current coolant water temperature and second setting temperature T2 comparison from outlet temperature meter 6 input.
If the comparative result in step S60 is that the outlet temperature of present engine 2 is below the second setting temperature T2, do not need cooling water circuit state for coolant water temperature is low, then control section 20 closed condition of keeping valve 10 proceeds to the step S40 of the off state of keeping cooling fan arrangement 5 simultaneously.
If being the outlet temperature of current motor 2, the comparative result in step S60 sets the T2 height than second, then control section 20 produces valves 10 and opens the control signal of a predefined valve switching amount B and be applied on the motoring part 12, drive cooling fan arrangement 5 (S70) with low speed simultaneously, proceed to the PI control step S80 of following valve switching amount.
Make motor 11 work according to the control signal motoring part of sending from control section 20 12, valve 10 is opened a switching amount B like this, opening of valve 10, the cooling water of motor is passed through the cylinder block of motor 2 and the heat that cylinder head absorbs motor in turn by water pump 1 extrusion, discharge by the outlet of cylinder head again, after process radiator 4 is emitted heat, once more by water pump 1, in the cylinder block of inflow engine 2.Cooling system can play cooling action through such cyclic process.
As a reference, valve switching amount B is set at the circuit cooling water inflow than the big value of valve switching amount A described above.
Secondly, control section 20 with the temperature of current motor 2 and determined setting temperature (T1 or T2) as input parameter passing ratio integral control (PI control), the switching amount of regulating valve 10 compactly can make coolant water temperature and setting temperature (T1 or T2) as the target S80 that most preferably is consistent.
Meanwhile, control section 20 compares S90 with the value that adds the temperature weighted value of having set (for example, about 30 ℃) on current coolant water temperature and the determined setting temperature (T1 or T2).
If, comparative result in step S90 is, current coolant water temperature adds that than on determined setting temperature (T1 or T2) value of temperature weighted value is big, then need stronger cooling performance owing to current coolant water temperature is quite high, control section 20 increases the heat exchange performance S100 of radiator 4 by high speed rotating cooling fan arrangement 5.
If the comparative result among the step S90 is, current coolant water temperature adds that than on determined setting temperature (T1 or T2) value of temperature weighted value is little, then control section 20 with current coolant water temperature once more with first temperature T 1 S110 relatively.
If, comparative result in step S110 is that current coolant water temperature is more than the first setting temperature T1, then control section 20 is back to the reverse side of valve switching amount PI control step S80, if current coolant water temperature is back to the step S10 that judges operating load for a short time than the first setting temperature T1.
As mentioned above, the present invention be with certain embodiments illustrate as an example but the present invention is not limited only to this embodiment.Those skilled in the art can easily carry out various deformation and modification to the present invention, and these distortion or modification all only utilize feature of the present invention, therefore wish within the scope of the present invention.
As mentioned above, the present invention can corresponding motor operating load condition and temperature compactly regulate cooling water inflow, can correspondingly with the loading condiction of motor most preferably control coolant water temperature thus, can reach the instable effect that prevents that the thermal shock and the state of cooling from detecting.
