0 rev/min, while receive block signal, then start infrared detector immediately, in probe vehicles whether someone, and by in-car human body
Thermal imaging signal output gives vehicle body ECU.
The remote control, key and signal receiving circuit are used to detect whether vehicle driver has lock operation action, such as
Fruit has block action, then transmits signal to infrared detector and anti-theft and alarm module.
The Engine ECU is used to receive CRANK SENSOR, and output one represents engine behavior
For high and low level signal to infrared detector, this signal is conveyed to the gate electricity in infrared detector together with block signal
Road, gate circuit output signal control infrared detector, makes infrared detector be worked in reasonable time.
The vehicle body ECU receives the engine rotational speed signal from Engine ECU by power CAN, receives simultaneously
The Studies of Human Body Heat imaging signal of infrared detector, if engine speed is 0, while infrared detector has Studies of Human Body Heat imaging signal defeated
Go out, illustrate that vehicle has stopped, driver has block action, but in-car someone, it is impossible to locking, now vehicle body ECU can export one
The individual unlocking signal that continues gives anti-theft and alarm module.
When the anti-theft and alarm module receives the lasting unlocking signal from the output of vehicle body ECU comfortable CANs, together
When receive the block signal of signal receiving circuit after, four signals can be exported simultaneously, to alarm；Pass through signal transmission circuit
Remind driver；Prevent car door locking simultaneously.When receiving unlocking signal, alarm is released.
Anti-theft and alarm module is matched by handset identity circuit with car owner's mobile phone, while launches electricity by signal
Road direction car owner's mobile phone sends fix information, realizes the function such as Remote, signal prompting.Meanwhile when vehicle falls among thieves illegally
Enter fashionable, car owner is reminded by signal transmission circuit in time, plays anti-theft function.
Further, four signals are specially：
Fixed signal is sent to car owner's mobile phone by the way that signal projector is point-to-point, control car owner phone vibrator vibrates, and
" in-car there are children, it is impossible to latches " printed words are shown on screen, remind car owner, it is impossible to lock a door.
Burglar alarm pulse signal controls electric horn breaker point unit coil interval bonding, makes electric horn breaker point unit discontinuous operation, loudspeaker
Interval is rung.
The control flasher work of burglar alarm signal, makes two side steering indicating light installed flickers.
Anti-theft and alarm module sends unlocking signal by signal wire to centrally controrlled locking system ECU, door lock ECU is controlled door lock
Fully open, car door is in unlocking condition.
A kind of automobile intelligent door lock control method, comprises the following steps：Infrared detector is arranged on roof, when engine puts out
When fighting and receiving block signal, detected at once, now, if in-car someone, by vehicle body ECU to burglar alarm
Control device output continues unlocking signal, after burglar alarm receives the unlocking signal provided by vehicle body ECU, sends report at once
Alert signal：Loudspeaker are made to alarm；Steering indicating light is double to be dodged；The vibration of car owner's phone vibrator is controlled, and " in-car has for display on screen
It is virgin, it is impossible to latch " printed words, remind car owner, it is impossible to lock a door；Unlocking signal is sent to door lock ECU, prevents car door from latching.
When under alarm condition, car owner presses unblock and is good for, and infrared detector is stopped, burglar alarm stops defeated
Go out alarm signal.When engine is in running status, system is without detection.
Compared with prior art, beneficial effects of the present invention are：
The present invention uses bussing technique, can improve vehicle safety performance, has hommization, intelligentized feature, and
Cost is relatively low, is adapted to popularization and application.
