Accompanying drawing explanation
Fig. 1 is air-conditioning control flow of the present invention.
The specific embodiment
Figure 1 shows that control flow method schematic diagram provided by the invention.By air-conditioner controller, complete following steps:
(1) start air-conditioning, initialize air-conditioning parameter.
(2) by control panel, to air-conditioner controller, input preset temperature T0, air-conditioner controller obtains preset temperature T0 and current vehicle interior temperature T1.
(3) relatively preset temperature T0 and vehicle interior temperature T1 are big or small, if T>T0, air-conditioner controller enters step (5); If T≤T0, compares preset temperature T0 and vehicle interior temperature T1 size every setting-up time t0;
(4) judge whether vehicle present engine starts, if not, control and utilize Motor Drive operation of air conditioner; If engine start, enters step (5);
Above step and existing motor vehicle driven by mixed power air conditioning control method are similar, and the demand temperature in predetermined car of take is standard, and demand preset temperature is entered in air-conditioner controller.Air-conditioner controller obtained after demand temperature with the car collecting in actual temperature make comparisons, as the condition that whether starts air-conditioning.Before starting of air conditioner, need the current driving condition of judgement vehicle, the present invention obtains status information by judgement engine speed: if engine speed is 0, illustrate when vehicle in front is in stopping or Motor Drive is travelled, cannot use engine for driven compressor, air-conditioner controller sends instruction, starts drive motor for compressor, from battery, draws energy drives air-conditioning work.
As one of inventive point of the present invention, step (4) if in engine speed to be detected non-vanishing, carry out following determining step (5): judgement is worked as vehicle in front and whether in accelerate or climbing etc., needed the state that motor torque is larger, if, control and open drive motor for compressor, utilize motor to drive operation of air conditioner; If vehicles failed is in accelerating or climbing state, control engine engages with compressor of air conditioner, by motor driven compressor of air conditioner, is worked.Wherein, " acceleration mode " comprises that vehicle launch and speed increase, and can judge as being installed on the data of the sensor collection in gas pedal by the checkout gear of vehicle self.When vehicle accelerates, often need stronger power, motor torque is larger, if now use motor driven compressor of air conditioner, be not easy to make full use of the current advantage of engine on the one hand, also can have influence on motor driven ability on the other hand, cause Conversion of Energy not thorough, waste energy; Therefore when motor-powered vehicle accelerates and start, use driven by power compressor of air conditioner more economical.
As a kind of scheme being more preferably, can also be at the default compressor rotary speed of air-conditioning control program, non-vanishing and not in accelerating or starting or climbing in the situation that at vehicle motor rotating speed, judge that whether current compressor rotary speed is higher than desired speed, if compressor rotary speed is higher than desired speed, control and open compressor driving motor, utilize motor to drive operation of air conditioner.
According to compressor of air conditioner efficiency working curve, compressor cooling coefficient increases and reduces with rotating speed, and its consumed power increases with rotating speed, and when compressor rotary speed is too high, its refrigerating efficiency is not high on the contrary.In design, conventionally consider the relation of compressor refrigeration system and consumed power, make compressor operating in the higher rotary speed area of efficiency.When compressor is driven by engine, compressor rotary speed is determined by engine speed, and engine is when vehicle high-speed is advanced, and is easy to make compressor of air conditioner because rotating speed is too high, to depart from its efficient rotary speed area.If now make compressor and engine throw off, by Motor Drive compressor operating, can make compressor cooling/thermal efficiency maintain in high efficiency region, carry high-octane transformation efficiency.
On this basis, the present invention also provides a kind of Vehicular air-conditioner compressor assembly, between compressor assembly and engine, is provided with electromagnetic clutch, and compressor assembly comprises motor, for drive compression machine, rotates; Controller, rotates and magnet clutch folding for controlling motor.In order to guarantee stability and the ease for operation of compressor assembly, compressor and motor share same rotating shaft, and controller, compressor, motor are arranged in same housing.When need are used Motor Drive compressor, by controller actuating motor, drive compressor rotation; When need are used motor driven compressor, by controller, control electromagnetic clutch and engage, now motor does not start, the rotation of driven by engine compressor, the passive idle running of motor.
The above is the most preferably condition that realizes technical solution of the present invention; do not get rid of the present invention and also exist other less preferred conditions can realize identical or similar technique effect, all improvement of doing on technical solution of the present invention basis and the scheme that can realize technique effect of the present invention are all within protection scope of the present invention.
