step 3: when car air-conditioner is subjected to mechanical energy driving work, if rotating speed of automobile engine reduces, micro controller system is accepted the tach signal that ECU sends, be not enough to support mechanical energy to drive car air-conditioner work through the existing rotating speed of computational discrimination, micro controller system 1 sends Continuity signal to the control end of optocoupler TL4, optocoupler TL4 conducting, at this moment, hybrid power storage battery 21 outgoing currents are by the input end S3 of controlled select switch, the second mouth S5, optocoupler TL4 powers to idling lifting electromagnetic valve 6, idling lifting electromagnetic valve 6 gets electric adhesive, idle-speed-enhancing valve 6 moves thereupon, to keep the stability of automotive engine 4 rotating speeds, can keep car air-conditioner work.
when car air-conditioner is worked, temperature sensor 7 in air-conditioner controller is synchronously measured vehicle interior temperature and is transferred in micro controller system 1 by Analog to Digital Converter 71, micro controller system 1 compares with regard to the comfort temperature of vehicle interior temperature and user's setting, if vehicle interior temperature fails to reach the comfort temperature of setting, micro controller system continues output signal, the mode of operation that keeps car air-conditioner, if vehicle interior temperature has reached the comfort temperature of setting, micro controller system 1 compares with regard to the comfort temperature of vehicle interior temperature and user's setting, if vehicle interior temperature has reached the comfort temperature of setting, micro controller system stops the output of Continuity signal, optocoupler TL1, optocoupler TL3, optocoupler TL4 all turn-offs, controlled select switch 2 input end S3 to the first mouth S4 open circuits, the second mouth S5 conducting, at this moment, magnetic clutch 5, idling lifting electromagnetic valve 6 all not electricly do not carry out any action, simultaneously, the driven by power end of compressor 3 also fails to receive electric energy, car air-conditioner stops refrigeration (heat) work, only optocoupler TL5 keeps conducting state, play blowing function, when temperature departs from comfort temperature again, optocoupler TL5 conducting again, compressor 3 continues to be driven by mechanical energy, car air-conditioner is resumed work.
Step 4: if automotive engine does not turn, air-conditioner controller judges that automobile is in halted state.at this moment, micro controller system waits for that wireless telecommunications chip 74 receives regularly pre-actuation signal, if wireless telecommunications chip 74 does not receive regularly pre-actuation signal, the hybrid power automobile air conditioner system does not start, continue to wait for regularly pre-actuation signal of reception, if wireless telecommunications chip 74 receives regularly pre-actuation signal, the hybrid power automobile air conditioner system enters the start by set date state, this moment optocoupler TL1, optocoupler TL2, optocoupler TL3, optocoupler TL4, the control end of optocoupler TL5 all not electric, so, controlled select switch 2 coil KA4, coil KA5 all not electric, at this moment, open contact KA4, open contact KA5, open contact KA6, open contact KA7 all disconnects, input end S3 to the first mouth S4, the second mouth S5 all opens a way, at this moment, blowing engine 10, magnetic clutch 5, idling lifting electromagnetic valve 6 all not electricly do not carry out any action, micro controller system 1 reads the chronometric data of clock chip 72, the timing that receives with communication chip 74 compares, when the chronometric data of clock chip 72 with equate with timing that communication chip 74 receives, this moment, air-conditioner controller entered pre-actuated state.Micro controller system 1 input/output port output signal, with optocoupler TL1 conducting, optocoupler TL2 turn-offs, and only has coil KA4 to get in controlled select switch 2 electric, open contact KA4 is closed, normally closed contact KA4 disconnects, open circuit between controlled select switch input end S3 to the second mouth S5, at this moment, electric current is from input end S3 input process normally closed contact KA5, open contact KA4, coil KA6 gets electric, and open contact KA6 is closed, circuit self-locking conducting between controlled select switch input end S3 to the first mouth S4; Hybrid power storage battery 21 outgoing currents are directly powered to compressor 3 by input end S3, the first mouth S4 of controlled select switch 2, the driven by power end of compressor 3; Simultaneously, micro controller system 1 is also to optocoupler TL5 output signal, optocoupler TL5 conducting, and to blowing engine 10 power supplies, car air-conditioner gets electric startup to DC regulated power supply 22 like this, enters mode of operation by optocoupler 5.
step 5: when the automobile-used air-conditioning work of driven by power, temperature sensor 7 in air-conditioner controller is synchronously measured vehicle interior temperature and is transferred in micro controller system 1 by Analog to Digital Converter 71, communication module 73 also synchronously receives the data of vehicle ECU, micro controller system 1 compares with regard to the comfort temperature of vehicle interior temperature and user's setting, if vehicle interior temperature has reached the comfort temperature of setting, micro controller system 1 stops the output of Continuity signal, optocoupler TL1, optocoupler TL2, optocoupler TL3, optocoupler TL4, optocoupler TL5 all turn-offs, controlled select switch 2 input end S3 to the first mouth S4, the second mouth S5 all opens a way, at this moment, blowing engine 10, magnetic clutch 5, idling lifting electromagnetic valve 6 all not electricly do not carry out any action, simultaneously, the driven by power end of compressor 3 also fails to receive electric energy, car air-conditioner quits work.if vehicle interior temperature does not reach the comfort temperature of setting, and the rotating speed of automobile engine data that communication module 73 receives ECU transmission equal zero or communication module 73 receives the rotating speed of automobile engine data of ECU transmission from zero growth rate, but when its rotary speed data not yet reaches the minimum data value that can drive car air-conditioner, micro controller system 1 holding signal output, keep optocoupler TL1 conducting, optocoupler TL2 turn-offs, guarantee circuit self-locking conducting between controlled select switch 2 input end S3 to the first mouth S4, car air-conditioner is maintenance work in power-actuated situation, if vehicle interior temperature does not reach the comfort temperature of setting, and when the rotating speed of automobile engine data that communication module 73 receives ECU transmission reach the minimum data value that can drive car air-conditioner, micro controller system 1 output signal, optocoupler TL1 is turn-offed, with optocoupler TL2, optocoupler TL3 conducting, open circuit between controlled select switch input end S3 to the first mouth S4, the driven by power end dead electricity of compressor 3, circuit turn-on between controlled select switch input end S3 to the second mouth S5, hybrid power storage battery 21 is by controlled select switch switch input terminal S3, the second mouth S5, optocoupler TL33 is to magnetic clutch 5 power supplies, magnetic clutch 5 gets electric adhesive, car air-conditioner is by mechanical energy driving work.
If the user wants to stop the work of car air-conditioner, can send signal to wireless communication module 74, micro controller system 1 stops the output of Continuity signal, optocoupler TL1, optocoupler TL2, optocoupler TL3, optocoupler TL4, optocoupler TL5 all turn-off, controlled select switch 2 input end S3 to the first mouth S4, the second mouth S5 all open a way, at this moment, blowing engine 10, magnetic clutch 5, idling lifting electromagnetic valve 6 all not electricly do not carry out any action, simultaneously, the driven by power end of compressor 3 also fails to receive electric energy, and car air-conditioner quits work.
Above-described embodiment is a kind of better scheme of the present invention, is not that the present invention is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
