POWER TRUNK LID SYSTEM


  1. CONSTRUCTION


    1. The luggage closer motor assembly consists of a power trunk lid ECU, a luggage closer motor, a reduction gear, an arm and so on.

    2. The luggage closer motor assembly moves the luggage compartment hinge assembly LH by driving the luggage closer motor to rotate the arm, thus opening and closing the luggage compartment door.

    3. The luggage closer motor consists of a motor, a magnet clutch, a Hall IC and so on. The Hall IC detects the position of the 64-pole magnet installed on the outer circumference of the magnet clutch. The detected result is input to the power trunk lid ECU, which judges the speed, position and opening and closing directions of the luggage compartment door.

  2. OPERATION


    1. Hall IC


      1. The power trunk lid ECU determines the jamming of the power trunk lid system upon receiving the signals from the Hall ICs.

      2. The power trunk lid ECU determines the luggage compartment door movement distance and the luggage compartment door opening/closing speed (door foreign object jamming) via the pulse signals from the Hall IC, and the luggage compartment door position (door movement direction) from the phase difference between the pulses from Hall IC 1 and Hall IC 2.

      3. If a foreign object gets jammed during opening or closing of the power trunk lid, the pulse width of the output signal from the Hall IC changes. The power trunk lid ECU interprets this as jamming, then stops the luggage closer motor assembly when the luggage compartment door is opening. If the luggage compartment door is closing, the ECU reverses the motor rotating direction.
