On/off switch, center body pillar switch and vehicle remote control switch.
In the present embodiment：The automobile automatic sliding door control system possesses manually and automatically pattern, manually and automatically pattern
Switching manually/automatic pattern switching switch realize.
When automatic sliding door control system is operated in manual mode, the driver's seat on/off switch in slide controlling switch, vehicle body
B posts switch and vehicle remote control switch is in failure state, and user can be by the way that handle reality is manually opened inside and outside slide or closes
Close slide.If slide is in full close position, slide control unit 1 does not control the automatic unlocking of sliding door lock body unit 4, and user, which operates, to be slided
Inside and outside door during handle, the tripper in Front Latch (preceding lock) door lock, Rear Latch (rear lock) door lock can be pulled, from
And the unblock of lock body unit is realized, during slide is opened, slide driver element does not possess AutoPlay function, and slide
Control system does not work without pinch resistant functionality, buzzer, but the arteries and veins of slide control unit still motor ripple detection circuit output
Number is rushed to be used to calculate stroke and the position of slide, when slide is moved at fully open position, the Open Latch in lock body unit
（Standard-sized sheet is locked）Slide can be fixed to be in the case of descending to prevent on-slip door and slid by door lock；It is sliding if slide is in fully open position
Door control unit 1 does not control the automatic unlocking of sliding door lock body unit 4 equally, when user operates handle inside and outside slide, can pull Open
Latch（Standard-sized sheet is locked）Tripper in door lock, so as to realize the unblock of lock body unit, during slide is closed, slide
Driver element does not possess AutoPlay function, and slide control system does not work without pinch resistant functionality, buzzer, but slide controls
The pulse number of unit still motor ripple detection circuit output is used for stroke and the position for calculating slide, even in manual mould
Under formula, power-operated sliding door system still has automatic locking function, i.e.,：Slide can trigger Rear successively before full close position is reached
Claw switches, half lock-switch, full lock-switch in Latch (rear lock) door lock, slide control unit are needed according to slide Rear
Latch (rear lock) door interlock switch signals are judged door position and Rear Latch (rear lock) state, and utilize PWM slow
Control the Close in Rear Latch (rear lock) door lock（Lock）Positive/negative turn of motor realizes the automatic locking of slide, prevent because with
Family operating physical force is too small to cause slide not completely close.
When automatic sliding door control system is operated in automatic mode, operator can be by sailing an on/off switch, inside and outside slide
Handle on/off switch, center body pillar switch and vehicle remote control switch realize the automatic opening or closing of slide.If slide is in complete
Closed position, slide control unit 1 receive slide open signal（Driver's seat opens/slide door inside and outside handle open/center body pillar switch/
Remote signal）Afterwards, slide control unit 1 will be communicated with the BCM of car body controller 6 by LIN buses or CAN and obtain vehicle
Status information, and by judging body information vehicle body IGN and ACC entity line signal, then pass through slide door lock
Switch, centrally controrlled locking system and virgin lock-switch signal judge slide door lock state, finally according to Latch door lock signals and is previously saved
Slide positional information carries out comprehensive descision to current slide position.When meeting that slide opens start condition, slide control is single
Member 1 controls the Release in Front Latch (preceding lock) using pwm signal by motor-drive circuit（Release）Motor operates
The tripper unblock in Front Latch (preceding lock) door locks and Rear Latch (rear lock) door lock is driven, realizes that slide is automatic
Unlocking function.After slide unlocks, slide control unit is using pwm signal control slide motor operating dragging slide
Open, when slide is run to fully open position, slide control unit can reduce slide speed automatically, prevent slide in standard-sized sheet
Violent stall.When slide is moved at fully open position, the Open Latch in lock body unit（Standard-sized sheet is locked）Door lock can consolidate slide
Fixed be firmly in prevent on-slip door in the case of descending slides.If slide is in fully open position, slide control unit receives slide pass
Close signal（Handle pass/center body pillar switch/remote signal inside and outside driver's seat pass/slide）Afterwards, slide control unit is believed using PWM
Number pass through motor-drive circuit and control Release in Front Latch (preceding lock)（Release）Motor operating drives Open
Latch（Standard-sized sheet is locked）Tripper unblock in door lock, realizes slide automatic unlocking function, then slide control unit 1 uses
Pwm signal control slide motor 3-1 operating dragging slides are closed, and when slide is apart from full close position 200mm, slide starts
Run slowly, until closed position.Slide is in it can trigger Rear Latch (rear lock) door lock successively before reaching full close position
Claw（Pawl）Switch, half lock-switch, full lock-switch, slide control unit are needed according to slide Rear Latch (rear lock) door lock
To door position and Rear Latch (rear lock), state judges switching signal, and Rear Latch are slowly controlled using PWM
Close in (rear lock) door lock（Lock）Positive/negative turn of motor realizes the automatic locking of slide, prevents from leading because user's operating physical force is too small
Slide is caused not completely close.
When automatic sliding door control system is operated in automatic mode, automatic sliding door control system possesses middle holding function,
If slide control switching signal is triggered in slide motion process（Handle on/off switch, car inside and outside driver's seat on/off switch, slide
Body B posts switch and vehicle remote control switch）, slide is by stop motion, but the clutch of now slide motor 3-1 connections is still
So it is in attracting state.Slide presses driver's seat on/off switch, slide Internal handle on/off switch, slide control again after stopping
System performs corresponding operation, if pressing center body pillar switch, sliding door outer handle switch, remote control switch, slide control system is held
Row breakdown action.If slide stops at some middle position in 15 minutes and pressed without switch, slide control system will close automatically
Slide is closed, avoids clutch long-time adhesive from causing to damage.
Further：The slide control unit 1 is electrically connected with anti-pinch sensor 7, and the anti-pinch sensor 7 is resistance-type
Sensor, in slide running, slide control unit determines whether object quilt according to anti-pinch sensor resistance value changes
Clamp, if so, the slide motor reversion of slide control unit control slide driver element.Anti-pinch adhesive tape resistance
Change characterizes whether Anti-pinch adhesive tape is extruded, original state, whereinFor initial resistance,＞, represent anti-pinch
Adhesive tape is not extruded, after Anti-pinch adhesive tape is squeezed,Rear resistance is extruded for Anti-pinch adhesive tape,＜.Slide
If slide control unit detects that slide motor electric current increases above threshold value or Anti-pinch adhesive tape when in operation to anti-pinch region
Resistance＜When, slide control unit is determined with object and clamps and control slide inverted running to standard-sized sheet or full close position.
Shown in Figure 5, the MCU module 1-1 of the slide control unit 1 electrically connects with warning device 8, MCU module 1-1
Alarm control signal is exported to send prompt tone to warning device 8, control warning device 8 and control vehicle body steering indicating light to flash.
