Abstract
The invention relates to an air conditioner control method for a hybrid automobile. The method comprises the following steps of: starting an air conditioner of the hybrid automobile; inputting a preset air conditioner temperature into an air conditioner panel controller, enabling the air conditioner panel controller to obtain a preset air conditioner temperature T0, an internal temperature T1 and an external temperature T2, and comparing T0 with T2; when T0 is larger than T2-S, transmitting T0 into the air conditioner controller through the air conditioner panel controller; when T0 is smaller than T2-S, transmitting a corrected temperature T0+K*(T2-S-T1) into the air conditioner controller through the air conditioner panel controller; controlling an engine to drive an air conditioner compressor to work by using the air conditioner controller through EUC (Equipment Under Control) of a transmitter; when T0 is larger than T2-S, displaying a practical external temperature and the T0; and when T0 is smaller than T2-S, displaying a practical external temperature and the temperature T0-K*(T2-S-T1). During application of the method, the temperature of the air conditioner is adjusted according to the external temperature, and the working time of the air conditioner compressor is shortened under the condition of not influencing the riding comfort of passengers, so that the engine is kept idle for a longer period of time, and the fuel consumption of the engine can be lowered effectively.
Description
Technical field
The invention belongs to technical field of hybrid power, relate to a kind of air conditioning control method of hybrid vehicle.
Background technology
At present, the application of hybrid power special air conditioner is also in the starting stage, and the air-conditioning of hybrid vehicle configurations mostly also is engine-driven traditional air conditioner.When not turning on the aircondition, there is the hybrid power bus of driving engine high-speed starting and stopping when low speed or parking, driving engine meeting auto-stop, to reduce fuel oil consumption, economize energy.As calculated, often more than 50% can be reached comparing hybrid power engine floor time ratio on the public bus network blocked up.Once air-conditioning is opened, at low speed or when stopping, during the design temperature of vehicle interior temperature out of reach Bus driver, compressor can work always, is unfavorable for fuel-economizing like this.During the broiling summer; the temperature of the public transit vehicle driver zone of general city operating mode is higher than the temperature in compartment; temperature sensor in car is generally contained in the front end of vehicle; being positioned at the temperature that the Temperature displaying board before compartment shows like this will be very high; understand to the higher sensation of a kind of temperature of passenger, require that driver opens air-conditioning very low, such air-conditioning compressor almost works always; cause engine down time ratio to decline to a great extent, finally affect oil-saving effect.
Summary of the invention
The object of this invention is to provide a kind of air conditioning control method of hybrid vehicle, when not affecting comfort of passenger, by the fuel oil consumption regulating the temperature of air-conditioning to reduce driving engine.
For achieving the above object, the air conditioning control method step of hybrid vehicle of the present invention is as follows:
(1) air-conditioning of hybrid vehicle is started;
(2) after air-conditioning panel controller input air-conditioning preset temperature, air-conditioning panel controller obtains the outer temperature T2 of air-conditioning preset temperature T0, vehicle interior temperature T1 and car, T2>T1>T0, and air-conditioning preset temperature T0 and the outer temperature T2 of car is compared;
(3) when air-conditioning preset temperature T0 be greater than the outer temperature T2 of car deduct setting value S time, air-conditioning preset temperature T0 is directly sent into air-conditioner controller by air-conditioning panel controller; When air-conditioning preset temperature T0 be less than the outer temperature T2 of car deduct setting value S time, air-conditioning panel controller will be revised temperature T0+K* (T2-S-T1) afterwards and send into air-conditioner controller, and described K is proportionality coefficient;
(4) air-conditioner controller drives air-conditioning compressor work by engine ECU controls engine;
(5) when air-conditioning preset temperature T0 be greater than the outer temperature T2 of car deduct setting value S time, electron temperature display board shows the air-conditioning preset temperature T0 after the outer temperature of actual car and setting; When air-conditioning preset temperature T0 be less than the outer temperature T2 of car deduct setting value S time, electron temperature display board shows the outer temperature of actual car and revised vehicle interior temperature T0-K* (T2-S-T1).
Further, the scope of described K is 0.1 ~ 1.
The air conditioning control method of hybrid vehicle of the present invention is when applying; the temperature of air-conditioning is adjusted according to the temperature outside car; when not affecting the comfort level that passenger takes; reduce the work-hours of air-conditioning compressor; thus make the time that driving engine is as far as possible many keep shutting down, effectively can reduce the fuel oil consumption of driving engine.
Accompanying drawing explanation
Fig. 1 is the diagram of circuit of the inventive method;
Fig. 2 is the air-conditioner control system functional block diagram of hybrid vehicle.
Detailed description of the invention
As shown in Figure 2, as shown in Figure 1, the concrete steps of method are as follows for method flow diagram for the air-conditioner control system of hybrid vehicle:
(1) air-conditioning of hybrid vehicle is started;
(2) after air-conditioning panel controller input air-conditioning preset temperature, air-conditioning panel controller obtains the outer temperature T2 of air-conditioning preset temperature T0, vehicle interior temperature T1 and car, T2>T1, and T0<T1, namely outdoor temperature is greater than vehicle interior temperature, and design temperature is less than vehicle interior temperature, and air-conditioning preset temperature T0 and the outer temperature T2 of car is compared;
(3) when air-conditioning preset temperature T0 be greater than the outer temperature T2 of car deduct setting value S time, air-conditioning preset temperature T0 is directly sent into air-conditioner controller by air-conditioning panel controller; When air-conditioning preset temperature T0 be less than the outer temperature T2 of car deduct setting value S time, air-conditioning panel controller will be revised rear temperature T0+K* (T2-S-T1) and send into air-conditioner controller, described K is proportionality coefficient, scope is 0.1 ~ 1, as T2-S-T1<0, air-conditioning panel controller is given the temperature that the temperature of air-conditioner controller and electron temperature display panel show above and is all got T0;
(4) air-conditioner controller drives air-conditioning compressor work by engine ECU controls engine;
(5) when air-conditioning preset temperature T0 be greater than the outer temperature T2 of car deduct setting value S time, electron temperature display board shows the air-conditioning preset temperature T0 after the outer temperature of actual car and setting; When air-conditioning preset temperature T0 be less than the outer temperature T2 of car deduct setting value S time, electron temperature display board shows the outer temperature of actual car and revised vehicle interior temperature T0-K* (T2-S-T1), (T2-S-T1) >0, can ensure that the temperature of actual feeding air-conditioner controller is higher than design temperature, reach oil-saving effect.
