POWER LIFTGATE (PLG) DRIVE UNIT CONSTRUCTION/OPERATION
PLG Motor
• Transmit the power of PLG motor via the
CLUTCH to rotate the PLG slider cable.
• PLG slider screws gets linked and wheels when
the PLG slider cable wheels, and then engages
with the PLG slider liner and the PLG slider liner
moves up and down.
Rotation Sensor
• The PLG motor's drive condition is converted into a pulse signal and transmitted to the PLG control module.
• If the pulse signal during open/close is interrupted, it is determined that there is an obstruction and the PLG
control module reverses the PLG motor.
• The open/close speed is calculated based on the pulse. The PLG motor output is adjusted by comparing the
target speed that is set for each liftgate position with the pulse as a base. Based on this, the liftgate open/close
operation is performed smoothly.
Clutch
• The clutch is normally released. The clutch is only engaged when the PLG system operates to transmit the
PLG motor operating force. The clutch engagement/release is performed based on the reception of the signal
from the PLG control module.
