1. |
Smart Tailgate unit (STG unit)
STG unit is installed inside the righthand side luggage side trim in the back.
STG unit uses a driving motor and operates two spindles.
It also controls the object jamming prevention by analyzing sensors inside of the anti-pinch strip. |
2. |
STG Latch Assembly
STG latch assembly consists of power latch(A) and power closing unit(B).
STG latch assembly is installed at the end of the tailgate and operates power lock/unlock mode under the STG unit control. |
3. |
STG spindle
STG spindle controls the tailgate’s opening and closing using the torque of the motor inside.
Recognize the tailgate''s driving direction by sending motor''s revolving direction signal inside of spindle to STG unit. |
4. |
Anti-pinch strip
APS is installed on the left and right side of the tailgate
and detects jamming of an object during Smart Tailgate closing
operation.
When jamming is detected, STG unit will immediately reverse tailgate to full open status.
Antipinch strip does not operate when tailgate is fully closed or fully open, is stationary or while opening. |
5. |
Wireless transmitter
Tailgate will start the Power Opening function when the
tailgate opening button on the wireless transmitter is pressed for more
than 1.0 second.
If the button is pressed when the tailgate is opening or closing, the tailgate will move in reverse direction. |
6. |
Overhead console switch
If the overhead console switch is pushed the tailgate will operate power opening function. |
7. |
Smart Tailgate inside switch
If the switch inside of the tailgate is pushed, the tailgate will start the power closing function. |
8. |
Smart Tailgate Buzzer
When an obstacle is detected or power function is not
performed properly in accordance to the user''s order, the alarming
buzzer will sound for 3 times.
And when power function is performed properly, the alarming buzzer will sound twice. |
Operating Principle |
1. |
Opening will start after signals from driver''s console
switch, tailgate handle switch, or wireless remote key(FOB) are
received. |
2. |
The latch motor will unlatched the tailgate by releasing the striker (via the SJB). |
3. |
To open the tailgate, the STG module will activate the tailgate spindle motors. |
4. |
The speed of the spindle motors is monitored via a hall sensor in the motor. |
5. |
Opening angle of the tailgate will be calculated from the number of pulses of the hall sensor.
|
1. |
Closing will start after signals from driver''s console
switch, tailgate inside switch, or wireless remote key(FOB) are
received. |
2. |
To close the tailgate, the STGM will operate the Spindle motors. |
3. |
The STGM monitors the Closing angle of the tailgate by counting the pulses from the hall sensors. |
4. |
The tailgate latch is meshed with the striker, and the latch locks onto the striker. (latch unlock -> latch lock) |
5. |
After the latch signal from the tailgate latch is received, STGM will stop the tailgate spindle motors operation. |
6. |
After latching, the PCU will start the clinching process until the clinched signal is received. |
7. |
The tailgate is fully closed, and the latch is fully locked. |
1. |
Maximum Point for Opening
The movement of opening direction beyond this position will
make the tailgate to reach the maximum basic position, and overload the
mechanical system(hinge).
So, opening movement beyond this position is impossible.
But, if the movement started from lower position, the tailgate will move beyond this point. |
2. |
Learned Mechanical End Position
Mechanical End Position is the mechanical limited position, and regarded as opened 100%.
In the process of the tailgate’s first opening, this position becomes Learning.
After the learning, the tailgate will not go beyond the maximum basic position that is defined as soft stop.
All of the positions will be defined by parameters that are designated by ECU. |
1. |
After mechanical End Position is learned, the basic position
defined by user will be regarded as same as the maximum basic position.
