Embodiment
As Fig. 1, core system parts of the present invention comprise: hand-held mobile terminal a0, communication base station NX, vehicle mounted communication terminal 10, entire car controller 20, battery management system 30, electrokinetic cell 40, block terminal 50, Electric Air-Conditioner Controller 60, electric air-conditioning compressor 70, vehicle interior temperature sensor 80, GPS 90 and corresponding software system.
Wherein from 10 to 90 is onboard system, is connected with the low pressure wire harness by the high pressure wire harness, passes through communication base station NX wireless connections from the communication of a0 to 10.
Vehicle mounted communication terminal 10 receives the link order that the user sends by hand-held mobile terminal a0, give the enable signal of entire car controller 20 work, entire car controller 20 is started working and is received query statement and the steering order that vehicle mounted communication terminal 10 is transmitted by signal circuit.Entire car controller 20 removes to control miscellaneous part and reads the information that miscellaneous part sends according to these instructions.
As accompanying drawing 2, the method of work that fault shows is: when the user passes through hand-held communication terminal a0 operation troubles display routine, vehicle mounted communication terminal 10 can receive the instruction of a0 and entire car controller 20 is sent enable signal, and entire car controller 20 is worked and received the fault diagnosis instruction and afterwards feeds back to user side a0 again by vehicle mounted communication terminal 10 after the operational diagnostics program.
As accompanying drawing 3, battery electric quantity shows that being also is that entire car controller 20 is received enable signal work and received the instruction of battery electric quantity remote inquiry, then by sending enable signal and request signal to battery management system 30, and be that the relay closes that in the block terminal 50 electrokinetic cell 40 is inserted powers on, battery management system 30 detects current voltage then, the SOC information feedback is given entire car controller 20, and entire car controller 20 back as calculated returns on user's the hand-held communication terminal a0 by vehicle mounted communication terminal 10.
As accompanying drawing 4, the implementation method of satnav is, when the user sends when reading GPS 90 information, entire car controller 20 allows GPS work on power, and read current terrestrial coordinates value by communication line, mode with digital signal is issued entire car controller, entire car controller 20 sends to vehicle mounted communication terminal 10 again and reads for the user, the hand-held communication terminal a0 that this coordinate figure is reflected in the user is exactly with this absolute coordinates position icon on map upward, this moment, user's hand-held communication terminal a0 just showed user's the current location and the current location of car, and function realizes.
The principle of work of regulating vehicle interior temperature by hand-held communication terminal a0 comprises the inquiry vehicle interior temperature and allows air-conditioning work.The user sends the instruction of inquiry temperature by handheld terminal a0, entire car controller 20 enable signals are received and given to vehicle mounted communication terminal 10, entire car controller 20 work, then after entire car controller 20 is received the temperature query statement that vehicle mounted communication terminal 10 transmits, give Electric Air-Conditioner Controller 60 enable signals and return to vehicle mounted communication terminal 10 then to send to user a0 at last by the value that Electric Air-Conditioner Controller 60 reads vehicle interior temperature sensor 80.When the user judge need to open air-conditioning with regulate in the car send instruction to target temperature value Y and by hand-held communication terminal a0 after, still there is vehicle mounted communication terminal 10 to be transmitted to entire car controller 20, after entire car controller 20 operation car load self-check programs pass through, the target temperature setting program that reruns also sends the temperature query statement in real time, allow block terminal 50 work on power by Electric Air-Conditioner Controller 60 and battery management system 30 then, electric air-conditioning compressor 70 refrigeration (also comprising the fan blower work that allows); Up to electric air-conditioning moved with target temperature and Current Temperatures air-conditioning can only ability etc. calculating working time value back (T value be entire car controller according to regulate target temperature and Current Temperatures table look-up draw), entire car controller 20 stops air-conditionings and moves and also finishes down.Especially, when vehicle is in charged state, promptly move high-tension electricity under the charging termination program behind the self-check program, by high-tension electricity on the adjustment program, and reach back high-tension electricity and point out the user whether to need to rerun charging procedure and charge down by electric motor car up to target temperature.For the specific implementation process of this routine adjustment program better is described, accompanying drawing 5 has been done detailed explanation with the form of FB(flow block).
