Description
Technical field
The present invention relates to field of automobile, particularly relate to warm-up control method and the device of a kind of electromotor.
Background technology
During engine cold starting, the time length of warming-up is most important to fuel oil efficiency of combustion and the discharge performance of electromotor.At present,
Electromotor generally uses thermostat, electronic thermostat and electronic water pump etc. to control the process of warming-up.
Thermostat, i.e. tradition thermostat, during engine warm-up, control the opening and closing in coolant systemic circulation water route,
Thus realize the warming-up of electromotor.The warming-up process of electromotor mainly includes three phases, and first stage is coolant partial circulating,
When the temperature (water temperature) below about 76 DEG C of coolant, controlling the valve closing of systemic circulation, coolant is not passed through radiator, only
Between engine water jacket and water pump, carry out the flowing of partial circulating, say, that coolant flow through cooling jacket-thermoregulator-water pump-
Cooling jacket, so that the temperature of engine coolant rises rapidly, thus ensures that electromotor reaches normal operating temperature.
Second stage is coolant mixing circulation, when the temperature of coolant is more than 76 DEG C, and the valve opening of control systemic circulation, and with
The aperture of the temperature increasing control valve door of coolant is gradually increased.Now, partial circulating and the systemic circulation of coolant is opened simultaneously and is carried out
The mixing circulation of coolant, but the time of mixing circulation is not the longest.Three phases is coolant systemic circulation, works as coolant
Temperature when being increased to about 88 DEG C, the valve controlling systemic circulation fully opens, and coolant all flows through radiator from water pump, also
That is, coolant flows through cooling jacket-thermoregulator-water pump-bypass oil radiator-radiator-thermoregulator-cooling jacket.Now,
Flow of cooling water route is long, and flow is big, and intensity of cooling is big, to promote the temperature rapid decrease of coolant, so that coolant
Temperature be unlikely to too high.
Electronic thermostat, on the basis of mechanical type thermostat, adds a resistance wire to realize electrically heated function, coordinates cold
But the action of systemic circulation valve is adjusted by liquid temp so that it is response ratio is very fast, just opens such that it is able to improve systemic circulation valve
Temperature when opening, it is achieved rapid warming-up.
Electronic water pump is then transmitted by the power of its internal electron clutch for clutch control water pump, controls the static of coolant and circulation, thus
Shorten warm-up period.
But the problem that presently, there are is, use thermostat exist when the valve of systemic circulation is crack coolant temperature relatively low and rise
The shortcomings such as temperature low-response.Electronic thermostat is used to improve limited to the process of warming-up, cold on the one hand can not regulating partial circulating pipeline
But the flow velocity of liquid, on the other hand each pipeline whole after the valve of systemic circulation is crack, in whole engine-cooling system
Rise and participate in circulation, cause the time of warming-up to lengthen.Additionally, control more complicated when using electronic water pump during warming-up,
Cause demarcating complicated and relatively costly.

Time interval, the current location controlling ball valve is positioned at the 5th predetermined angle, so that the second pipeline valve is opened to the 5th pipeline valve.Specifically
For, when the Current Temperatures of coolant is more than 95 DEG C and is less than or equal to 105 DEG C, the first control unit 3100 controls ball valve
Current location is in 126deg.Now, the second pipeline valve 200 fully opens, the 3rd pipeline valve the 300, the 4th pipeline valve 400
Opening with the 5th pipeline valve 500, the 6th pipeline valve 600 is closed.As it is shown in fig. 7, at the band of engine water pump 2
Under Dong, coolant is circulated further in the pipeline of engine water pump 2, engine cylinder cover 3 and transmission oil cooler 10
Flowing.Thus, it is possible to realize transmission oil cooler 10 is heated.
The warmup control device of the electromotor of the embodiment of the present invention, along with the temperature of engine coolant is gradually increasing, to starting
Parts in machine cooling system carry out stepped heating stage by stage, when coolant temperature is increased to a certain degree, control little following
Ring valve is small to be opened, and is cooled down engine cylinder cover by the small circulation of coolant, and along with coolant temperature continues to raise,
Oil cooler and transmission oil cooler is made to participate in step by step in circulation, hence in so that temperature prioritised in engine water jacket reaches
Preferably temperature.The warmup control device of the electromotor of the embodiment of the present invention, during warming-up when greatly reducing engine cold-start
Between, improve the warming-up efficiency of electromotor, and friction when reducing engine cold-start, reduce electromotor oil consumption and
While discharge capacity, extend the service life of electromotor.
Additionally, the warmup control device of the electromotor of the embodiment of the present invention, when coolant temperature is relatively low, if driver's cabin has warm
The demand of wind, then can quickly raise in this circulation cold by supercharger with the series circulation flowing of coolant in the pipeline of steam air heater
But the temperature of liquid, just can send warm braw to driver's cabin after electromotor just starts, and substantially increases the ride quality of passenger.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and former
Within then, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
