Outward, based on the information received, control unit 50 controls the rotary speed of pump 60 and selectively opens or closes pump 60.
With reference to Fig. 3 to Fig. 4, will be described in detail the control method of the heat-exchange system of each embodiment according to the present invention.
As shown in Figure 3, if vehicle becomes on-state in the step s 100, then control unit in step s 110
50 diagnosis starting pump 60.
If starting the diagnosis of pump 60, then control unit 50 will be used for the letter operating pump 60 in the step s 120
Number it is delivered to pump 60.
If pump 60 receives this signal and operates, then control unit 50 receives the behaviour about pump 60 in step s 130
Make the signal of situation, and determine that pump 60 the most normally operates.The normal operating of pump 60 is not it is meant that pump 60 breaks down
Or the sensor of the situation of detection pump 60 does not break down.
If pump 60 the most normally operates, (such as, the sensor of the situation that pump 60 breaks down or detects pump 60 is sent out
Raw fault), then in step S180, control unit 50 operates apartment warning, such as emergency warning lamp.Emergency warning lamp can be with cluster side
Formula (at a cluster) is arranged, so that driver is capable of identify that the situation of pump 60.
If pump 60 normal operating, then control unit 50 makes operation and the standard of pump 60 of pump 60 in step S140
Standby operation stops.Additionally, step S140 can complete before electromotor 10 starts.
If electromotor 10 operates in step S150, then in step S160, control unit 50 determines whether to receive oil
Information with the temperature of coolant.Oil represents the gear oil for lubricating differential gear 70.It is said that in general, gear oil and automatically change
The temperature difference between speed device oil is little, thus the temperature of the temperature of automatic transmission fluid or gear oil can be used as oil temperature.This
Outward, according to each embodiment of the present invention, oil temperature is the oil temperature in differential gear 70 or automatic transmission 80, and coolant temperature is
Coolant temperature before inflow heat exchanger 90.But, oil temperature and coolant temperature can be defined otherwise.
If not receiving the information of the temperature of oil and coolant, then control unit 50 is in safe mode in step S170
In pump 60 is operated.Safe mode is the pattern of pump 60 safety operation.In safe mode, the operation of pump 60 can be with separately
Outer usual manner is configured.If additionally, pump 60 operates in safe mode, then control unit 50 in step S180
Operation emergency warning lamp.
If receiving the information of the temperature of oil and coolant, then control unit 50 is according to this information meter in step s 200
Calculate the rotary speed of pump 60.
If calculating the rotary speed of pump 60, then in step S210, control unit 50 is according to the rotary speed pair calculated
Pump 60 operates.Rotary speed according to this information can be configured according to target pump performance with other usual manner.
Step S160 to S180 and step S200 to S210 repeats in engine operation.
In the operating process of pump 60, in step S220, control unit 50 determines whether electromotor 10 stops.If sent out
Motivation 10 does not stops, then control unit 50 is back to step S160.If electromotor 10 stops, then controlling in step S230
Unit 50 processed stops pump 60.
Fig. 4 is the flow process of the another kind of exemplary control method for controlling exemplary hot exchange system according to the present invention
Figure.In the diagram, step S100 to S150 and step S180 are identical with the step in Fig. 3, thus omit it and specifically describe.
As shown in Figure 4, if electromotor starts operation in step S150, then control unit 50 in step S160
Determine whether to receive the information of the temperature of oil and coolant.If receiving the information of the temperature of oil and coolant, then in step
In S162, control unit 50 determines that whether coolant temperature is less than the first predetermined temperature t0.
If coolant temperature is less than the first predetermined temperature t0, then in step S190, control unit 50 closes pump 60.
If coolant temperature is less than the first predetermined temperature t0, then due to the operation of the equipment of the such as heater in vehicle, may
There will be heat loss.Therefore, pump is turned off to prevent the heat loss of coolant.
If coolant temperature is not less than the first predetermined temperature t0, then determine that in step S164 oil temperature is whether less than the
Two predetermined temperature t1.
If oil temperature is less than the second predetermined temperature t1, then in step S192, control unit 50 opens pump 60.Namely
Saying, owing to oil temperature is relatively low, automatic transmission 80 and differential gear 70 are rapid by the heat exchange between execution oil and coolant
Heating.Therefore, in order to improve the heat exchanger effectiveness between oil and coolant, pump 60 is opened.
If oil temperature is not less than the second predetermined temperature t1, then determine in step S166 whether oil temperature makes a reservation for less than the 3rd
Temperature t2.Here, the second predetermined temperature t1 is less than the 3rd predetermined temperature t2.
If oil temperature is less than the 3rd predetermined temperature t2, then in step S194, control unit 50 closes pump 60.Work as oil temperature
During greater than or equal to the second predetermined temperature t1 and less than the 3rd predetermined temperature t2, oil can in the case of pump does not operates fully
Ground lubrication automatic transmission 80 and differential gear 70.Therefore, pump is closed such that the heat of each embodiment according to the present invention
The waste energy minimization of exchange system.If oil temperature is not less than the 3rd predetermined temperature t2, then control single in step S196
Unit 50 opens pump 60.
3rd predetermined temperature t2 is the highest.If oil temperature is too high, then automatic transmission 80 and differential gear
70 may be overheated.Therefore, oil should be cooled.
If oil temperature is greater than or equal to the 3rd predetermined temperature t2, then oil should be cold by the heat exchange with coolant
But.Therefore, pump 60 is opened, thus improves the heat exchanger effectiveness between oil and coolant.
Those skilled in the art can at random arrange first, second, and third predetermined temperature t0, t1 and t2.Additionally,
Each embodiment of the present invention uses three predetermined temperatures, but is not limited to this.A series of multiple predetermined temperature can be used.
As described above, according to each embodiment of the present invention, owing to heat-exchange system applies simultaneously to automatic transmission
And differential gear, the heat exchange between oil and coolant can efficiently perform, and the fuel consumption of vehicle can reduce.
Additionally, due to three kinds of fluid heat exchanges each other in a heat exchanger, so that unnecessary cooling
Minimization of loss and the durability of driving equipment can be improved.
