When all door (Front, Rear) power window auto-up switch is operated, safety function is activated.

- Safety function condition When detect the force of 100N during the window rising, window is reversed.
- Length of window reversing (except holding the auto-up switch) When detect the jamming during the 4 mm ~ 250 mm from top of the door. --> Window is reversed until 300 mm from top of the door. When detect the jamming over the 250 mm from top of the door. --> Window is reversed until 50 mm from jamming position. --> Window is reversed 50 mm or bottom position in case of 50 mm reversing distance. When detect the jamming over 300 mm from top of the door. --> Window stops at reverse point.
- Length of window reversing (holding the auto-up switch) When detect the jamming during holding the auto-up switch. --> Window is reversed until 25 mm from jamming position. Auto-up function is not available during the 5 seconds from above condition. --> When holding the auto-up switch, window is operated as a manual-up function. (Safety function is not activated.) When detect the jamming during holding the auto-up switch again. --> Window is reversed until 25 mm from jamming position. When holding the auto-up switch after 5 seconds from above condition. --> Window is reverse until 25 mm from jamming position.
- Safety function is not available area Safety function is not available during the 4 mm from top of the door.
Initializing Method Of The Safety Power Window
- Position counter and position initialization Position counter Window position counting is implemented by use of one Hall Effect sensor (HEF) connected to timer capture unit of the Controller with a resolution of 180° electrical. Even the battery was separated from the car, it must keep the window position information. Position initialization For position initialization, position counter detect the upper mechanical stop and lower mechanical Position. Motor control unit (MCU) allow only Manual mode activity (without ASD Anti-Squeeze Detection algorithm) feature) before to be initialized. Initialization means the condition to move the window system with full anti-pinch function and related functions by detecting the window travel distance (Upper/Lower mechanical limits). Conditions for initialization are de-initialized position counter Power window switch Up activated block condition detected (no motor movement of more than 1 count during 1 sec/ SW dependent) Switch action with De-initialized condition: Up direction: Manual & Auto P/WDW sw input --> manual mode; Down direction: Manual P/WDW sw input --> manual mode, + Auto s/w input --> auto mode Re-initialization During re-initialization, position counter is set to "zero" at upper block position to compensate counting errors by software, mechanical tolerances or physics. Conditions for re-initialization are initialized position counter. window at upper block position (capture range EEPROM programmable) block condition detected (no motor movement of more than 1 count during 1 sec/ SW dependent) De-initialization The system initialization/calibration will be lost in the following cases: After parameter modification via diagnostic Wrong EEPROM checksum at ECU wake-up or power-on Movement outside predefined window stroke (above learned top position, below predefined bottom position) De-initialization after a defined number (EEPROM) of reversals without re-initialization in the upper seal (activation/de-activation controlled by EEPROM value). A window down movement or switching off the window lifter permission resets the reversal counter value (activation by EEPROM bit). De-initialization after a defined number of movements (EEPROM) without re-initialization in the upper seal (activation/de-activation controlled by EEPROM value) Special de-initialization procedure: The special window lifter de-initialization procedure works as follows: System is initialized Move window below soft-stop position (position EEPROM adjustable) Press MANU-down switch and keep it pressed Apply permission signal (serial-link = PIN 6) ON --> OFF --> ON within 2 seconds (time EEPROM adjustable) Soft stop function In order to reduce noise and mechanical stress, the window movement is stopped under control of the ECU before the bottom position is reached. The clearance is 0 / +10 mm (at 11.5 V to 14.5 V). To activate the soft bottom stop function, the top reference position and bottom reference position have to be initialized. Therefore, the window is lifted into the top position until the block condition is detected. This position is taken as top reference position. Afterwards, the window is moved to the bottom position until the block condition is detected (mechanical stop). This position is taken as bottom reference position. The bottom reference position is re-initialized: When window is operated down starting from soft stop position Every "9" stops at soft stop position. Thermal protection Thermal protection by software module is implemented to prevent from destruction of motor during overload condition. Motor temperature is estimated by integrating squared motor current as an estimate for heating power integral. When estimated motor temperature exceeds EEPROM programmable upper limit, motor is deactivated for fixed delay time (default value = 30 sec.) Thermal shutdown during a window operation will not interrupt the operation due to safety reasons. Operation time limiter Maximal operation time of power window motor is limited to 15 sec (EEPROM programmable). Continuous reverse Current Number of Continuous reverse of window is 5. With the below condition, this counter Will be initialized. IG OFF DOWN signal ON WINDOW CLOSE
