Fig. 3 is the flow process of the heating method implementing a kind of hybrid vehicle exemplifying according to another exemplary of the present invention
Figure, the present embodiment is applied to illustrate in the implementation environment shown in Fig. 1 with the heating method of this hybrid vehicle.
Step 301, processing unit detection electrokinetic cell whether normal work.Execution step 302.
After hybrid vehicle starts, processing unit can detect electrokinetic cell whether normal work, and detection method can
To be that whether detection electrokinetic cell damages and detects whether temperature of powered cell is less than the minimum predetermined temperature (temperature of electrokinetic cell
Cannot normal work when too low), when electrokinetic cell damages or temperature of powered cell is less than minimum predetermined temperature, processing unit is true
The non-normal work of determined power battery.
Do not damage in electrokinetic cell, and when temperature of powered cell is higher than minimum predetermined temperature, processing unit determines power electric
Pond normal work.
Step 302, processing unit detects the control instruction of user, and control instruction includes heating request and stopping heating please
Ask.Receive the heating request that user sends in processing unit, and during the non-normal work of electrokinetic cell, execution step 303.
Processing unit can detect the control instruction of user it is preferred that processing unit can be according to the control instruction of user
Control electric fan.Such as, when processing unit receives the heating request that user sends, electric fan is controlled to open；In processing unit
When receiving the stopping heating request that user sends, electric fan is controlled to close.Electric fan can accelerate the radiating of heater core
Speed, the effect of lifting heating.
Wherein, heating request can be that user heats request to driving cabin, and/or, the defrosting request of user.
It should be noted that receive the stopping heating request that user sends in processing unit, and the normal work of electrokinetic cell
When making, terminate flow process；Receive, in processing unit, the heating request that user sends, and during electrokinetic cell normal work, execute step
Rapid 306；In the non-normal work of electrokinetic cell and processing unit receive user stopping heating request when, execution step 307.
Step 303, receives, in processing unit, the heating request that user sends, and during the non-normal work of electrokinetic cell, place
Whether reason unit detection engine water sleeving temperature is less than water jacket minimum predetermined temperature.It is higher than that water jacket is minimum in engine water sleeving temperature
During preset temperature, execution step 304；When engine water sleeving temperature is less than water jacket minimum predetermined temperature, execution step 305.
The temperature of engine water jacket can directly affect the temperature of engine, and when engine temperature is relatively low, can be to starting
Machine causes damage.
Step 304, when engine water sleeving temperature is higher than water jacket minimum predetermined temperature, it is electricity that processing unit controls engine
Heater provides electric energy, and controls electric heater and engine water jacket jointly to provide hot water for heater core.
When the temperature of engine water jacket is higher than minimum predetermined temperature it is believed that engine temperature is in safe range,
Engine water jacket can provide hot water for heater core.
In implementation environment shown in Fig. 1, can show as in engine water sleeving temperature is higher than water jacket minimum predetermined temperature
When, processing unit controls engine 11 to provide electric energy for electric heater 12, controls triple valve 16 to open, and controls electronic water pump 14
Close, in the water and electric heater 12 in the engine water jacket 13 that on engine water jacket 13, the mechanical water pump 131 of setting drives
Current direction heater core 15.

Set or electric heater be individually for heater core provide hot water, but electronic water pump cannot normal work when, need to utilize machine
Tool water pump drives water circulation, i.e. processing unit controls triple valve 16 to open, and controls the mechanical water pump of setting on engine water jacket 13
131 drive the current direction heater core 15 in water and electric heater 12 in engine water jacket 13.
Step 305, when engine water sleeving temperature is less than water jacket minimum predetermined temperature, it is electricity that processing unit controls engine
Heater provides electric energy, and controls electric heater to provide hot water for heater core.
When engine water sleeving temperature is less than water jacket minimum predetermined temperature, for avoiding engine temperature too low, typically obstructed
Crossing engine water jacket provides hot water to heater core, i.e. processing unit controls engine 11 to provide electric energy for electric heater 12,
Processing unit controls triple valve 16 to close, and controls electronic water pump 14 to open, and electronic water pump 14 drives the water in electric heater 12
Flow to heater core 15.
Step 306, after processing unit determines electrokinetic cell normal work and receives the heating request that user sends, sends out
Motivation and electrokinetic cell provide the electric energy of electric heater jointly, or engine is provided separately the electric energy of electric heater.
In electrokinetic cell normal work and when user has heating to need, user can be with unrestricted choice by engine and power electric
Pond provides the electric energy of electric heater jointly, or engine is provided separately the electric energy of electric heater, can be according to the electricity of electrokinetic cell
Amount is selected, i.e. the electric energy of electric heater, electrokinetic cell electricity when electrokinetic cell electricity is relatively low, are provided separately by engine
The electric energy of electric heater, when more sufficient, is provided jointly by engine and electrokinetic cell.
Electric heater obtain electric energy after, can individually to heater core offer hot water, or together with engine water jacket to
Heater core provides hot water.
Step 307, in the non-normal work of electrokinetic cell and processing unit receive user stopping heating request when, process
Unit controls electric heater to open, the electric energy being sent with consumption of engine.
In the non-normal work of electrokinetic cell, the electric energy that engine sends cannot be stored in electrokinetic cell it is necessary to disappear at once
Consume, thus the electric energy that can be sent with opening electric heater consumption of engine.
It should be added that, the heating method of hybrid vehicle provided in an embodiment of the present invention, by heating
On device core body, electric fan is set, improves the radiating efficiency of heater core, also reducing user and not heating needs but heating
There is hot water stream fashionable in device core body, the radiating efficiency of radiator core body.
It should be added that, the heating method of hybrid vehicle provided in an embodiment of the present invention, by starting
When machine jacket water temperature is too low, only passing through electric heater provides hot water to heater core, has reached and has avoided engine temperature too low
The effect of the engine damage of Shi Zaocheng.
