Abstract
An air-conditioner electrical control system for a hybrid electric vehicle comprises a temperature sensor and a control system connected with the temperature sensor. A main vehicle control unit is arranged in the control system, the output end of the main vehicle control unit is connected with a compressor control signal line and an air-condition control line of the hybrid electric vehicle, a compressor is connected onto the compressor control signal line, a power supply commutation circuit is connected onto the air-condition control line of the hybrid electric vehicle, and the power supply commutation circuit is respectively connected with a storage battery and a generator. The air-condition electrical control system is provided with the main vehicle control unit and the power supply commutation circuit, when an engine works, the air-conditioner generator serves as a power supply, when the engine does not work, the system power supply is switched to the main vehicle storage battery which is used for guaranteeing work of an evaporator fan. Therefore, the air-conditioner electrical control system can guarantee that the evaporator fan of a vehicle runs when the engine stops work, thereby saving fuel consumption to the greatest extent under the premise of guaranteeing comfort level of passengers.
Description
Technical field
The utility model relates to air conditioning for automobiles, specifically relates to a kind of electric control system of hybrid vehicle air-conditioning.
Background technology
At present; The oil consumption of conventional passenger vehicle and be emitted on and occupy higher ratio in single-piece energy resource consumption and the environmental pollution; And power-actuated automobile not only involves great expense, travelled distance is limited, and must rely on a large amount of batteries electric energy is provided, so the development of hybrid vehicle seems more and more important.Along with the development of hybrid vehicle, the air conditioning for automobiles that matches requires also that blower fan still can move when main car is stopped paying out motivation.And mostly traditional air conditioning for automobiles is engine drive, when driving engine is not worked, can't use.
Summary of the invention
The purpose of the utility model provides a kind of hybrid vehicle air-conditioning electric control system of under the prerequisite that guarantees comfort of passenger, as far as possible saving oil consumption for car load.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises temperature sensor and the coupled control system that connects; Main car control unit is set in control system; The mouth of said main car control unit connects compressor control signal line and hybrid vehicle air-conditioning control line; Wherein connect compressor on the compressor control signal line, connect power supply switch circuit on the hybrid vehicle air-conditioning control line, power supply switch circuit connects storage battery and electrical generator respectively.
Described power supply switch circuit is made up of DC contactor and DC contactor open contact, and wherein DC contactor is positioned on the hybrid vehicle air-conditioning control line, and the DC contactor open contact is positioned on the storage battery working power.
Adopt the utility model of technique scheme, be provided with main car control unit and power supply switch circuit thereof, when in engine operation, use the air-conditioning electrical generator to make power work; When engine shutdown, system power supply switches on the main automobile battery, uses main automobile battery to guarantee evaporation fan work.It can satisfy automobile evaporation fan when engine shutdown and also can move like this, thereby under the prerequisite that guarantees comfort of passenger, is car load saving oil consumption as far as possible.

Fig. 2 is the utility model electrical control figure.
Fig. 3 is the control flow chart of the utility model.
The specific embodiment
As shown in Figure 1; The utility model comprises temperature sensor and the coupled control system that connects; Main car control unit is set in control system, and the mouth of said main car control unit connects compressor control signal line and hybrid vehicle air-conditioning control line, wherein connects compressor on the compressor control signal line; Connect power supply switch circuit on the hybrid vehicle air-conditioning control line, power supply switch circuit connects storage battery and electrical generator respectively.Above-mentioned power supply switch circuit is made up of DC contactor KM1 and DC contactor open contact KM1-1, and wherein DC contactor KM1 is positioned on the hybrid vehicle air-conditioning control line, and DC contactor open contact KM1-1 is positioned on the storage battery working power.
Like Fig. 2, shown in Figure 3, the utility model a/c system is on the basis of traditional air-conditioning system, to increase power transfer device, compressor control signal line and hybrid vehicle air-conditioning control line, and two control lines all link to each other with main car control unit.In order both to guarantee passenger's traveling comfort, can reduce the oil consumption of main car engine again as far as possible, the vehicle interior temperature that the utility model a/c system can be set is 25-32 degree.When vehicle interior temperature during more than or equal to design temperature, compressor operating, the compressor control signal line keeps the 24V high level, and main car engine forced service can not stop.
When vehicle interior temperature during less than design temperature, compressor stops, compressor control signal line output low level, and this moment, main car engine allowed to shut down.If driving engine is not shut down, then keep the normal condition operation, control flow is identical with traditional air-conditioning; If engine shutdown, hybrid vehicle air-conditioning control line output 24V high level then, DC contactor KM1 connects, and system power supply is switched to main automobile battery by the air-conditioning electrical generator, and controller detects forced evaporation blower fan low cruise behind this high level signal.Controller continues temperature signal in the inspection vehicle, if vehicle interior temperature does not need compressor and starting again, then maintains the original state; If vehicle interior temperature needs compressor and starting again; Then compressor control signal line output 24V high level as if main car engine or stopped status, is then wanted force start at this moment; The output of hybrid vehicle air-conditioning control line also becomes low level by the 24V high level; DC contactor KM1 breaks off, and the air-conditioning power supply switches the adjusting system electrical generator that makes the return trip empty by main automobile battery, and the subsequent control flow process is identical with traditional air-conditioning.
