Description of drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is system construction drawing of the present invention.
The specific embodiment
See also shown in Figure 1, a kind of electronlmobil air-conditioner control system, comprise carload controller 1, a switching device 2, an air-conditioning compressor 3 and an air-conditioning fan device 4, also comprise an air conditioning control device 5, described switching device 2 is connected with entire car controller 1, described entire car controller 1 is connected with air conditioning control device 5, and described air conditioning control device 5 is connected with air-conditioning compressor 3, and described air-conditioning fan device 4 is connected with entire car controller 1.The starting of air conditioner signal whether entire car controller 1 (being VCU) detector switch device 2 transmits.If the air-conditioning actuation signal is arranged, then entire car controller 1 wakes air conditioning control device 5 up by the CAN bus, sends air-conditioning rotating speed message for simultaneously air conditioning control device 5.Air conditioning control device 5 converts corresponding voltage and frequency adjustment air-conditioning compressor 3 rotating speeds to according to air-conditioning rotating speed message.Entire car controller 1 starts air-conditioning fan device 4 simultaneously, and then air-conditioning fan device 4 is started working, and has then finished the starting of air conditioner process.When switching device 2 stops to send the starting of air conditioner signal to entire car controller 1, entire car controller 1 stops to send the CAN message to air conditioning control device 5, air conditioning control device 5 is closed air-conditioning compressor 3, entire car controller 1 is closed air-conditioning fan device 4 then, then air-conditioning quits work, and has namely finished air-conditioning and has closed closed procedure.
Switching device 2 can be a simple switch, as ship type switch, but be based on attractive in appearance and consideration system integration, switching device 2 can comprise CD/DVD main frame 20 and a switch sensor, CD/DVD main frame 20 is the standard configuration of present automobile basically, and by switch sensor being connected on the CD/DVD main frame 20, CD/DVD main frame 20 is connected on the entire car controller 1, avoided switch sensor separately with being connected of entire car controller 1, simplified cabling.Switch sensor can be air conditioning switch sensor 22 or blower switch sensor 21, when air conditioning switch sensor 22 or blower switch sensor 21 are closure state, then CD/DVD main frame 20 sends entire car controller 1 with the starting of air conditioner signal, then entire car controller 1 just can be finished above-mentioned starting of air conditioner process, otherwise when air conditioning switch sensor 22 or blower switch sensor 21 were off-state, CD/DVD main frame 20 did not send the starting of air conditioner signal to entire car controller 1.Certainly, air conditioning switch sensor 22 and blower switch sensor 21 also can be received on the CD/DVD main frame 20 simultaneously, then when air conditioning switch sensor 22 and blower switch sensor 21 are in closure state simultaneously, CD/DVD main frame 20 will send the starting of air conditioner signal to entire car controller 1, otherwise when air conditioning switch sensor 22 or blower switch sensor 21 have one during for off-state, CD/DVD main frame 20 will not send the starting of air conditioner signal to entire car controller 1.
Switching device 2 also comprises an evaporator temperature sensor 23, evaporator temperature sensor 23 is connected with CD/DVD main frame 20, then CD/DVD main frame 20 can get access to the temperature data of evaporator, if evaporator temperature mal, namely be higher than preset temperature, then do not send the starting of air conditioner signal to entire car controller 1, if the normal switch sensor simultaneously of temperature is in closure state, then send the starting of air conditioner signal.
Based on the consideration of battery-driven car air conditioning comfortableness, native system also comprises a refrigerating capacity demand sensor 6, and refrigerating capacity demand sensor 6 is connected with described entire car controller electricity 1 signal.Entire car controller 1 receives the refrigerating capacity desired signal that refrigerating capacity demand sensor 6 sends, entire car controller 1 signal according to demand sends corresponding air-conditioning rotating speed CAN message to air-conditioner controller, and air-conditioner controller is regulated compressor rotary speed according to the CAN message information and reached target refrigerating capacity demand.
System also includes a pair of sensor 7 that compresses switch, and described two sensors 7 that compress switch are connected with entire car controller 1.When two sensors 7 that compress switch were in closure state and switching device 2 starting of air conditioner of transmission signal is arranged, entire car controller 1 just carried out the starting of air conditioner process; Sensor 7 is in off-state or switching device 2 does not send the starting of air conditioner signal otherwise ought two compress switch, and entire car controller 1 does not carry out starting of air conditioner.When entire car controller 1 detects two sensors 7 that compress switch and is in closed condition, entire car controller 1 stops to send air-conditioning rotating speed CAN message to air conditioning control device 5, air conditioning control device 5 is closed air-conditioning compressor 3, and entire car controller 1 is closed air-conditioning fan then, and air-conditioning quits work.
Air conditioning control device 5 comprises an air-conditioner controller 50 and air-conditioner controller relay 51, and air-conditioner controller 50 is connected with entire car controller 1 with air-conditioning compressor 3 simultaneously, and air-conditioner controller relay 51 is connected with entire car controller 1 with air-conditioner controller 50 simultaneously.Increase the power supply that air-conditioner controller relay 51 is used for controlling air-conditioner controller 50, closing air conditioning control device 5 gets final product for 51 times electricity of air-conditioner controller relay, then can close the power supply of air-conditioner controller 50, both simplify control flow, again can energy savings.In the time will starting air conditioning control device 5, then should power on for earlier air-conditioner controller relay 51, give again to send air-conditioning rotating speed CAN message to control air-conditioner controller 50.Air-conditioner controller 50 converts corresponding voltage and frequency adjustment air-conditioning compressor 3 rotating speeds to according to air-conditioning rotating speed CAN message.
Air-conditioning fan device 4 includes an air-conditioning fan relay 40 and an air-conditioning fan 41, and air-conditioning fan is connected with the air-conditioning fan relay, and air-conditioning fan relay 40 is connected with entire car controller 1.In the time will opening air-conditioning fan device 4, closed air-conditioning fan relay 40 gets final product, and when closing air-conditioning fan device 4, disconnects air-conditioning fan relay 40 and gets final product.
Though more than described the specific embodiment of the present invention; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present invention; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present invention, all should be encompassed in the scope that claim of the present invention protects.
