Obtain after electric energy at electric heater, can with engine water jacket jointly for heater core provide hot water, or separately for heater core provides hot water.
In sum, the heating method of the hybrid vehicle that the embodiment of the present invention provides, by driving engine directly for electric heater provides electric energy, solve prior art medium power battery when cannot normally work, electric heater does not have electric power supply, heat energy is provided, the problem that heating effect is poor by means of only engine water jacket; Reach no matter whether electrokinetic cell can normally work, electric heater can both obtain electric energy and provide the effect of hot water for heater core.
Fig. 3 is the diagram of circuit of the heating method of a kind of hybrid vehicle according to another exemplary embodiment of the present invention, and the present embodiment is applied in the implementation environment shown in Fig. 1 with the heating method of this hybrid vehicle and carrys out casehistory.
Step 301, whether processing unit detects electrokinetic cell and normally works.Perform step 302.
After hybrid vehicle starts, whether processing unit can detect electrokinetic cell and normally work, method of inspection can be detect electrokinetic cell whether whether to damage and detect temperature of powered cell lower than minimum predetermined temperature (cannot normally work when the temperature of electrokinetic cell is too low), electrokinetic cell damage or temperature of powered cell lower than minimum predetermined temperature time, processing unit determination electrokinetic cell does not normally work.
Do not damage at electrokinetic cell, and temperature of powered cell higher than minimum predetermined temperature time, processing unit determination electrokinetic cell normally works.
Step 302, processing unit detects the control command of user, and control command comprises heating request and stops heating request.Receive at processing unit the heating request that user sends, and when electrokinetic cell does not normally work, perform step 303.
Processing unit can detect the control command of user, and preferably, processing unit can control electric fan according to the control command of user.Such as, when processing unit receives the heating request that user sends, control electric fan and open; When processing unit receives the stopping heating request that user sends, control electric fan and close.Electric fan can accelerate the radiating rate of heater core, promotes the effect of heating.
Wherein, heating request can be that user heats request to driving compartment, and/or, the defrosting request of user.
It should be noted that, receive at processing unit the stopping heating request that user sends, and when electrokinetic cell normally works, process ends; Receive at processing unit the heating request that user sends, and when electrokinetic cell normally works, perform step 306; When electrokinetic cell does not normally work and processing unit receives the stopping heating request of user, perform step 307.
Step 303, receives at processing unit the heating request that user sends, and when electrokinetic cell does not normally work, whether processing unit detects engine water sleeving temperature lower than water jacket minimum predetermined temperature.When engine water sleeving temperature is higher than water jacket minimum predetermined temperature, perform step 304; When engine water sleeving temperature is lower than water jacket minimum predetermined temperature, perform step 305.

It should be noted that, when engine water sleeving temperature is higher than water jacket minimum predetermined temperature, also can by engine water jacket or electric heater separately for heater core provides hot water, but when electronic water pump cannot normally work, need to utilize mechanical water pump to drive water circulation, that is, processing unit control triple valve 16 is opened, and the mechanical water pump 131 controlling that engine water jacket 13 is arranged drives the current direction heater core 15 in the power and water temperature booster 12 in engine water jacket 13.
Step 305, when engine water sleeving temperature is lower than water jacket minimum predetermined temperature, processing unit controls driving engine and provides electric energy for electric heater, and controls electric heater for heater core and provide hot water.
When engine water sleeving temperature is lower than water jacket minimum predetermined temperature, for avoiding engine temperature too low, generally do not provide hot water by engine water jacket to heater core, namely, processing unit controls driving engine 11 and provides electric energy for electric heater 12, processing unit controls triple valve 16 and closes, and controls electronic water pump 14 and open, and electronic water pump 14 drives the current direction heater core 15 in electric heater 12.
Step 306, after processing unit determination electrokinetic cell normally works and receives the heating request that user sends, driving engine and electrokinetic cell provide the electric energy of electric heater jointly, or driving engine provides separately the electric energy of electric heater.
When electrokinetic cell normally works and user has heating to need, user can be provided the electric energy of electric heater by unrestricted choice jointly by driving engine and electrokinetic cell, or driving engine provides separately the electric energy of electric heater, can select according to the electricity of electrokinetic cell, that is, when electrokinetic cell electricity is lower, the electric energy of electric heater is provided separately by driving engine, when electrokinetic cell electricity is more sufficient, jointly provided the electric energy of electric heater by driving engine and electrokinetic cell.
Electric heater can provide hot water to heater core separately, or provide hot water to heater core together with engine water jacket after obtaining electric energy.
Step 307, when electrokinetic cell does not normally work and processing unit receives the stopping heating request of user, processing unit controls electric heater and opens, the electric energy sent with consumption of engine.
When electrokinetic cell does not normally work, the electric energy that driving engine sends cannot be stored into electrokinetic cell, must consume at once, thus can the electric energy that sends of opening electric heater consumption of engine.
It should be added that, the heating method of the hybrid vehicle that the embodiment of the present invention provides, by arranging electric fan in heater core, improve the radiating efficiency of heater core, also reduce user do not heat need but have hot water to flow in heater core time, the radiating efficiency of radiator core body.
It should be added that, the heating method of the hybrid vehicle that the embodiment of the present invention provides, by when engine water sleeving temperature is too low, provide hot water by means of only electric heater to heater core, reach the effect of the engine damage caused when avoiding engine temperature too low.
It should be added that, the heating method of the hybrid vehicle that the embodiment of the present invention provides, by when electronic water pump damages, the mechanical water pump put by engine water drives water circulation, when reaching electronic water pump damage, also can carry out the effect heated.
In sum, the heating method of the hybrid vehicle that the embodiment of the present invention provides, by driving engine directly for electric heater provides electric energy, solve prior art medium power battery when cannot normally work, electric heater does not have electric power supply, heat energy is provided, the problem that heating effect is poor by means of only engine water jacket; Reach no matter whether electrokinetic cell can normally work, electric heater can both obtain electric energy and provide the effect of hot water for heater core.
