Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As shown in Figure 1, intelligent vehicle car body control module of the present utility model comprises input buffering module 1, A/D modular converter 2, power driver module 3, diagnosis output module 4 and main control module 5.
Wherein, input buffering module 1 is used to receive engine input signal, the diagnosis switching signal of diagnostic device 9 transmissions and the switching signal of a plurality of first car electrics loads, and received signal is carried out sending to main control module 5 after the buffered.The switching signal of above-mentioned a plurality of first car electrics loads comprises the windscreen wiper feedback input signal, the lampet input signal, drive the closing and opening side doors signal, copilot closing and opening side doors signal, windscreen wiper is input signal (the batch (-type) switch input signal of wiper) intermittently, door lock telepilot input signal, the seat belt switch signal, rear window defrost switch signal, the central controlled lock switching signal, the back door switching signal, wash and scrape switch signal (cleaning the switching signal of interlock wiper), 1 grade of input signal of ignition switch, 2 grades of input signals of ignition switch, key inductive switch signal, parking brake switching signal and sliding gate switching signal.Above-mentioned buffered comprises conversion, impedance matching and the high-low level conversion (swinging to) of level.
The analog signal conversion that A/D modular converter 2 is used for receiving from the second car electrics load is to send to main control module 5 after the digital signal.In a kind of embodiment of the present utility model, the second car electrics load is a batch (-type) wiper 8.
Power driver module 3 all links to each other with main control module 5 with the input end of diagnosis output module 4, power driver module 3 is controlled a plurality of car electrics loads under the control of main control module 5, diagnosis output module 4 is realized communicating by letter with external diagnosis equipment 9 under the control of main control module 5, so that control assembly internal wiring and sensor are carried out functional check.This power driver module 3 can adopt Darlington pipe array chip.
Main control module 5 receives the signal that a plurality of sensors send, according to the output of signal controlling power driver module 3 that sends from input buffering module 1, A/D modular converter 2 and a plurality of sensor and diagnosis output module 4.In a kind of embodiment of the present utility model, these a plurality of sensors comprise vehicle speed sensor 6 and rain sensor 7; This main control module 5 is MCU.Rain sensor 7 is arranged on the rainfall induction type wiper, it can detect the intensity of rainfall automatically, and detected real-time information fed back to car body control module, car body control module carries out analyzing and processing according to the information that receives, and makes judging accurately with control rain shaving electrical machine relay and working under suitable pattern.
Adopt car body control module of the present utility model can realize following function:
Seat belt warning: at seat belt braces state not, if open ignition switch, securing band emergency warning lamp and alarm song began warning work between 5～7 seconds; If braces securing band at this moment, the securing band emergency warning lamp continues bright in the remaining time, simultaneously the alarm song cease operation.
The speed of a motor vehicle latches automatically: in the ignition switch open mode, if the speed of a motor vehicle reaches 20 kilometers/hour, then car door is locked automatically; Even do not lock at the speed of a motor vehicle exit door more than 20 kilometers/hour in addition, also can automatic locking on; Car door automatically terminated lockup state when igniting was closed.
Firing key Aperture Illumination: open the driving side door, illuminating lamp and door switch interlock, firing key Aperture Illumination lamp is opened, and shuts to keep approximately behind the door that firing key Aperture Illumination lamp extinguishes after 10 seconds, if but turned on ignition switch at 10 seconds with interior insertion key then firing key Aperture Illumination lamp extinguishes.
Power window control time lag: close the back in 30 seconds in ignition switch, major and minor driving motorized window still can be worked, if but open cab door at this moment, will prolong for 30 seconds this moment.In the time that prolongs, if close entrance door, then the time is reset.
Lampet does not close warning: at lampet switch opens state, take out firing key after, if open cab door, then hummer starting.At this moment, though lock cab door also can involution to not locking state.
Men Weiguan warning: as long as have Yishanmen not shut when cab door, copilot chamber door, sliding gate, this 4 fan door of back door, main control module 5 will be exported the signal of a Men Weiguan and give combination instrument, be arranged on the Men Weiguan stand by lamp meeting Chang Liang in the combination instrument, remind the driver to shut up the door carefully.
Firing key is reminder not: when firing key inserted keyhole, if open the driving side door, then the tinkle of bells sounded, and this moment, button rebounded automatically if lock a door then by door lock knob, and door is got back to the state do not locked again; This function is inoperative in the ignition switch open mode.
Back defroster timer: under the engine start state, if open back defroster switch, back defroster work 12 minutes; In the back defroster work, if open again the back defroster switch the back defroster close; Behind the defroster end-of-job, if 10 minutes with the interior defroster switch of pressing once more, then worked 6 minutes.
The hand braking warning of removing of driving a vehicle: if use parking brake when vehicle stops, main control module 5 emergency warning lamp in the meeting control combination instrument after receiving the parking brake switching signal is opened, reaching more than 3～5 kilometers/hour as if speed of operation under this state, do not use parking brake if remove yet, the emergency warning lamp flicker in the combination instrument.
Clean the interlock wiper: the ignition switch open mode, if the operated wash switch, by main control module 5 control rain shaving electrical machine relays, wiper is started working in 0.6～1.2 second, close wash switch after, wiper is worked and is stopped after 2-3 time.
Induction type cup lamp: the cup lamp switch if turn on the pilothouse side door then the chamber lamp is opened, closes and kept approximately behind the door 2 seconds when door interlock position, slowly extinguishes then, extinguishes fully after 3 seconds; In the lamp operating process of chamber, when opening a switch or closing pilothouse side door lock switch, the chamber lamp is closed at once; If the time of opening of door switch can not be responded to work below 0.2 second.
After adopting car body control module of the present utility model, when increasing whole vehicle functions, the relay that has reduced some functions of decentralised control originally uses, from the car load angle since number of spare parts reduce, control is concentrated, and has reduced price, has saved installing space, the trouble spot is significantly reduced, and reliability and security also obtain certain raising.
