Detailed description of the invention
The object of the invention is to propose a kind of plug-in hybrid-power automobile passenger cabin and heat management system scheme, the existing orthodox car engine working mode of plug-in hybrid, also pure electronic mode of operation is had, under pure electronic mode of operation, traditional driving compartment heating and defrosting-defogging function can not meet, therefore increase a set of water ptc heater 6 of crossing and meet this demand, but under hybrid electric working pattern, continue to use this to cross water ptc heater 6 to heat, the energy of high-tension battery can be consumed, reduce pure electronic continual mileage, the heating management system of this patent design, under novel point is hybrid mode, utilize the high-temperature cooling water flowed out from driving engine to pass through water to cross water ptc heater 6 pairs of passenger accommodationes and heat, thus the function of defrosting-defogging outside the demand reaching passenger's heating, can also be realized.Reduce energy consumption, extend the continual mileage under electric-only mode, improve the economy of car load, more embody the environmental protection characteristic of hybrid electric vehicle.
As shown in Figure 1, the present invention utilizes triple valve 5 to achieve two-way circulation, be respectively driving engine and heat main cycle and electro heat short circle, wherein driving engine heats main cycle for heating water route successively via water-circulating pump 2, coolerstat 3, the triple valve 5B entrance of driving engine 1, and triple valve 5C exports, cross water ptc heater 6 and driving compartment heating unit 7 forms circulation loop; Electro heat short circle is for heating water route successively via PTC water pump 4, triple valve 5A entrance, and triple valve 5C exports, cross water ptc heater 6 and driving compartment heating unit 7 forms circulation loop.Driving compartment heating unit 7 comprises attached gelled pipeline, and to the blowing engine of air blast in operator's compartment, air-conditioning duct in pipeline and operator's compartment.
Crossing water ptc heater is an electric heater, and high-tension battery is taken from institute's electricity consumption, and it is by the characteristic of own material, and environmentally the change of temperature regulates the thermal power of self to export, by the power consumption optimal control of temperature booster minimum.
As shown in Figure 2, when passenger accommodation starts heating and heating defrosting-defogging, by controlling the path of triple valve 5, under pure electronic mode of operation, start PTC water pump 4 and use electro heat short circle, under engine working mode, start water-circulating pump 2 and use driving engine to heat main cycle.Namely when chaufeur has heating and defrosting, a defrosting function request, hybrid controller according to vehicle operation pattern, engine operation, or pure electronic mode of operation (driving engine does not work) starts different soft circulation circuits.Main cycle is then engine cooling water-flow circuit, and short circle is then for electro heat crosses water PTC water-flow circuit.Under main cycle pattern, PTC water pump 4 cuts out, and cross water ptc heater 6 and close, water flows into from the B mouth of triple valve 5, flows out from C mouth.Under short circle pattern, PTC water pump 4 is opened, and cross water ptc heater 6 and open, water flows into from the A mouth of triple valve 5, flows out from C mouth.
Before short circle pattern is switched to main cycle pattern, the cooling water temperature that hot water temperature's (electronic PTC heating) in short circle is flowed out than driving engine is high, in order to avoid the moment Temperature jump switched, must guarantee that the cooling water temperature that in water PTC, water temperature angle value can not flow out than driving engine is high 10 degrees Celsius.
The changing method that driving engine heats main cycle and electro heat short circle is, under chaufeur has heating to ask request, if when engine operation and rotating speed are more than 500 rpms, PTC water pump 4 cuts out, cross water ptc heater 6 to close, start water-circulating pump 2, triple valve 5B, C direction conducting, heat greatly circulation and start; If driving engine does not work, and vehicle is under electric-only mode, and water-circulating pump 2 is closed, and starts PTC water pump 4 and crosses water ptc heater 6, triple valve 5A, C direction conducting, littlely heats circulation and starts.
In order to control the temperature in crew department better, the temperature methods that driving engine heats main cycle and electro heat short circle control driving compartment is as follows:
Electro heat short circle controls the temperature methods of driving compartment: after triple valve 5A, C conducting, postpone to open PTC water pump 4 in 1 second, start water circulation, as shown in Figure 3, occupant sets heating temperature value and deducts temperature value in actual driving compartment, difference carries out PID control, what obtain needs control crosses water ptc heater 6 heating target temperature, target temperature deducts actual mistake water ptc heater 6 actual temperature again, difference carries out PID control, what obtain needs control crosses water ptc heater 6 heating power, controlled water ptc heater 6 add thermal output according to PTC heating power.In order to avoid in same temperature point vibration saltus step, in temperature rises and declines in passenger accommodation, different temperature difference points is set, carries out the control of PTC power.
The temperature methods that driving engine heats main cycle control driving compartment is, occupant sets heating temperature value and deducts temperature value in actual driving compartment, difference carries out PID control, obtain needing to control heating target temperature, target temperature deducts actual coolerstat 3 cooling water expansion tank leaving water temperature again, difference carries out PID control, obtains coolerstat 3 delivery rate needing to control, controls the hot water discharge of coolerstat 3 according to delivery rate.Namely coolerstat 3 cooling water expansion tank leaving water temperature and aquifer yield are inverse relation.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
