Wherein, the method for the embodiment of the present invention can determine different according to temperature, operating mode, use condition of engine etc.
Engine-cooling system control strategy.Wherein, the control strategy of engine includes but not limited to：Warming-up pattern, is stopped at radiating mode
Control strategy under machine pattern and fail-safe mode carries out control valve under each strategy different aperture control, with reality
Now to the reasonable distribution of cooling agent.
Specifically, when engine is in warming-up pattern, if the water temperature of engine is located at the first warm area, pass through institute
Control valve control first interface, second interface and third interface is stated to close；If the water temperature of engine is located at the second warm area, lead to
Crossing control valve controls the first interface to open the first predetermined angular range, and second interface and third interface is controlled to close,
In, the ceiling temperature of the first warm area is less than the lower limit temperature of the second warm area；If the water temperature of engine is located at third warm area, lead to
It crosses control valve control first interface and is opened into maximum angle, and second interface and third interface is controlled to open the second predetermined angular model
It encloses, wherein, the ceiling temperature of the second warm area is less than the lower limit temperature of third warm area, lower limit angle of the second predetermined angular range etc.
In the upper limit angle of the first predetermined angular range.
Further, when engine is in the warming-up pattern, judge whether heater cores start；It is if it is, logical
Crossing control valve controls the first interface and second interface to close, and third interface is controlled to be opened into maximum angle.
That is, in engine-cooling system, oil cooler, which is connected in coolant distribution unit, not to be rotated
In the interface of ball valve control, rotary ball valve simultaneously controls warm wind circuit, bypass circulation and systemic circulation circuit, works as engine
During cold start-up, to accelerate the rapid warming-up of engine, as shown in figure 4, control strategy is as follows：
First stage：The water temperature tmot of engine meets 55 DEG C of ranges of -40 DEG C≤tmot ＜ (i.e.：First warm area) when, control
Rotary ball valve processed is failure to actuate, at this point, bypass circulation, warm wind circuit, systemic circulation circuit are turned off, the cooling agent in cylinder cover water jacket is not
Flowing.
Second stage：When the water temperature tmot of engine meets 55 DEG C≤tmot ＜, 75 DEG C of ranges (i.e.：Second warm area) when, this
When control rotary ball valve open part bypass circulation, warm wind circuit and systemic circulation circuit are turned off, cold in cylinder block and head water jacket
But agent microfluidic, ball valve act in the range of 3 °~18 °；
Phase III：When the water temperature tmot of engine meets 75 DEG C≤tmot, 100 DEG C of ranges of ＜ (third warm area), at this time
Whole bypass circulations and part warm wind circuit can be opened according to water temperature value maximum, systemic circulation circuit is closed, at this time using cylinder body
Interior cooling agent heats machine oil, and ball valve acts in the range of 18 °~61 °；
During engine warm-up, when user opens warm wind, ball valve is rotated at once to the position of 178 ° of absolute angle, this
When bypass circulation, systemic circulation circuit be turned off, warm wind circuit is all turned on, so as to ensure the heating demands of user.
When the water temperature of engine reaches the ceiling temperature of third warm area, then engine is controlled to enter radiating mode.I.e.：Work as hair
After the completion of motivation warming-up, i.e. when the water temperature tmot of engine reaches 100 DEG C, engine enters radiating mode.Enter in engine
After the radiating mode, including：Target water temperature is determined according to environment temperature, the rotating speed of engine and load；According to target water
Temperature adjusts first interface and the opening angle of second interface by control valve, wherein, target water temperature is more than the lower limit of third warm area
Temperature.
In the above description, as shown in figure 4, when the first stage, during water temperature rises to 55 DEG C by -40 DEG C, ball valve
Always it is in the position of 3 ° of absolute angle；When in second stage, during water temperature rises to 65 DEG C by 55 DEG C, ball valve is maintained at
The position that 10 ° of absolute angle, during water temperature rises to 75 DEG C by 65 DEG C, ball valve is maintained at the position of 18 ° of absolute angle；Work as place
When the phase III, during water temperature rises to 85 DEG C by 75 DEG C, ball valve is maintained at the position of 28 ° of absolute angle, when water temperature is by 85
It DEG C rises to during 95 DEG C, ball valve is maintained at the position of 38 ° of absolute angle；During water temperature rises to 100 DEG C by 95 DEG C, ball valve
It is maintained at the position of 61 ° of absolute angle.
As shown in figure 5, the control strategy under radiating mode is：
Target water temperature is obtained according to parameters such as environment temperature, rotating speed, loads, by adjusting the rotation angle of rotary ball valve,
The opening degree of systemic circulation circuit and bypass circulation is controlled, warm wind loop feature is opened, and rotary ball valve is only in 61 °~120 ° ranges
It is inside adjusted, to maintain target water temperature between 85 DEG C -105 DEG C.
When ECU monitoring engine water temperatures reach less than 75 DEG C, engine enters warming-up pattern, using under warming-up pattern
Control strategy.
When engine is shut down, the third interface is controlled to be opened into maximum angle by control valve.Further, it is sending out
When motivation is shut down, while electric water pump is controlled to run, electric water pump is controlled to close afterwards until reaching the predetermined time (such as 10 minutes).
When engine is in warming-up pattern, if cooling system breaks down, engine is controlled to shut down；Work as engine
During in radiating mode, if cooling system breaks down, engine is controlled to enter high temperature protection pattern；If water temperature senses
Device and/or position sensor detection failure, then control first interface to third to be interfaced to maximum opening angle by control valve.
I.e.：Fail safe strategy, when engine is in warming-up pattern, ball valve, motor, gear, Circuit Board Trouble etc. occur leads to ball
The failure that valve cannot rotate, then shut down.When engine is in radiating mode, there is ball valve, motor, gear, Circuit Board Trouble
Etc. the failure for causing ball valve that cannot rotate, then engine high-temperature protected mode is performed；If there is water temperature exception or position sensor
Abnormal to wait the failure for not influencing ball valve rotation, then ball valve goes to systemic circulation maximum opening position.
