Outside Mirror Function (DDM)

The Mirror operation function in DDM contains of the following function.

  1. Behavior For Normal State
    1. Mirror Select Switch Operation

      In order to avoid miss-operation by user, Mirror select (L) and Mirror select (R) are read out as follows.

      If both Mirror select (L) and Mirror select (R) is pushed at same time, Indicate LED will light Left LED.

      H (History): H memorize Current state When go to disable from enable. And then, Go to memorized state If Return to enable that satisfied IGN SW DDM condition.

      MIRR SEL SW is according to SE SW CTRL State as follow table.

    2. Manual switches Operation
      1. Mirror operation is carried out in DDM according to user operation of direction switches when the following conditions are satisfied.
        • IGN switch DDM = (ACC, IGN, or ST).
        • Mirror select switch is MIRR SEL SW = LEFT.
        • Only one of direction switches is pressed ON (Mirr SW Up, Mirr SW Down, Mirr SW Left or Mirr SW Right).
      2. If one of the above conditions is not satisfied, DDM stops mirror motor control immediately.
      3. DDM shall not output continuously to same direction more than 15s±500ms.

        DDM transmits mirror select switch (MIRR SEL SW) and direction switches condition (MIRR SW Up, MIRR SW Down, MIRR SW Left, and MIRR SW Right) to ADM via CAN communication as follows. ADM will control mirror according to these CAN signals

    3. Playback Operation

      DDM controls mirror position according to memorized position by memory function, and DDM has 4 memories for positioning that is selected by user operation of P1 or P2 switches and Fob1 or Fob2.

      1. Shift-lever is P position
      2. All direction switches (Mirr SW Up, Mirr SW Down, Mirr SW Left, and Mirr SW Right) are OFF.
      3. Not Memory mode
      1. The playback operation is carred out when the following conditions are satisfied.
        1. P1 and P2 SW Playback
          • IGN SW DDM = IGN ON (IGN, ST) or. DR Door Open condition (DRV DR SW = OPEN) or Operating *30s timer.
          • DDM starts positioning if one of IMS P1 or P2 (Ims Memory=P1 ON or Ims Memory=P2 ON) switches is pressed ON
          • DDM transmits one of IMS P1, and P2 switches condition to ADM via can communication when DDM starts positioning. ADM controls playback function according to this CAN signal and memory mode

            P2 ON OFF ON (Holding 150ms)
        2. Fob1 and Fob2 Playback

          DDM transmits one of Fob1, and Fob2 Playback Start command to ADM via can communication when As for DDM, it starts Playback with last received the fob command when becoming IGN SW DDM = Key Off → Not Key Off in the condition which is necessary for Fob Playback Enable Mode after sending a corresponding Playback command (after ADM receives Playback command from DDM).

          INPUTS OUTPUTS

          Unlock & No2 & Key OFF→Not Key OFF OFF ON (Holding 150ms)
      2. The playback (both P1 or P2 SW and Fob1 or Fob2) is stopped immediately and canceled when one of the following conditions is satisfied.
        • Memory Enable Mode
        • Shift-lever is NOT P position.
        • Any direction switch (Mirr SW Up, Mirr SW Down, Mirr SW Left, and Mirr SW Right) is ON when Only IGN SW DDM=ACC or IGN or ST
      3. When playback is carrying out, the playback will be completed, even if IGN switch is IGN OFF (Key Off, Key In or ACC) or DR Door Close condition (DRV DR SW = CLOSE) or Ended *30s timer.

        * 30s timer: Playback operation is able to operation for 30s after DR Door Close condition (DRV DR SW = CLOSE).

    4. Memory Operation
      1. DDM enters to memory mode (ready to memory) when the following conditions are satisfied.
        • IGN SW DDM = IGN ON. (IGN, ST)
        • Shift-lever is P position
        • Vehicle speed is < 3Km
        • DDM enters memory mode if IMS set switch is pressed ON by user operation.
        • DDM transmits MEM P1 CMD or MEM P2 CMD to ADM and other ECU via CAN communication when IMS P1 or P2 switch is pressed ON in memory mode as follows.
          INPUTS OUTPUTS
          Memory Ims Memory MEM P1 CMD MEM P2 CMD
          Disable - OFF OFF
          Enable OFF OFF OFF
            P1 ON ON (Holding 150ms) OFF
          P2 ON OFF ON (Holding 150ms)
        • DDM transmits MEM Fob1 CMD or MEM Fob2 CMD to ADM and other ECU via CAN communication when receives MEM Fob Lock = "1" or "2" from IPM.
          INPUTS OUTPUTS
          Memory MEM Fob Lock MEM Fob1 CMD MEM Fob2 CMD
          Disable *2 OFF OFF
          Enable OFF OFF OFF
            "1" ON (Holding 150ms) OFF
          "2" OFF ON (Holding 150ms)
      2. DDM exits memory enable mode when one of the following conditions is satisfied.
        • IGN SW DDM = IGN OFF. (Key Off, Key In, ACC,)
        • Shift-lever is NOT P position
        • Vehicle speed is ≥ 3Km
        • Position is memorized by P1 or P2 switch mentioned below.
        • Position is memorized by Fob1 or Fob2 of MEM Fob Lock = "1" or "2".
        • Elapsed 5s in memory enable.
      3. When DDM is in memory mode, if IMS set switch is pressed ON again by user operation, memory mode will be extended for 5s.

      When DDM is in memory mode (ready to memory) and no manual operation is performing,

      1. DDM memorizes position ONCE if one of IMS P1 or P2 or Fob1 or Fob2 Input is executed by user.
      2. After memorized, DDM not memorizes position even if P1 or P2 or Fob1 or Fob2 Input is executed again. In order to memory position again, memory mode should be ENABLED again.
      3. Save position is memorized according to current operation as follows.
        Current Operation Save position Note
        Current Target Before Auto Reverse
        Moving Down       This is impossible because memory function is performed in P position and Auto reverse is performed in R position.
        Down
        Manual In Reverse Down
        Returning     X In the RETURNING, The position of before Auto reverse is memorized.
        Stop X      

        X is memorized position.

    5. Auto Reverse

      The Auto Reverse function controls mirror position according to Shift-lever. When Shift-lever changed to R position, mirror position will go down 5 degrees below automatically. And then Shift-lever change back to P position, mirror position will go back previous position (before Auto reverse) automatically.

      1. In the NORMAL state mentioned above, DDM starts reverse down when one of the following conditions is satisfied.
        1. Shift-lever changes to R position and keeps R position ≥ (350±50ms), under mirror select switch is in NOT NEUTRAL and IGN SW DDM = IGN ON and Current Vertical AD> VvReverse min.
        2. Mirror select switch changes to NOT NEUTRAL from NEUTRAL, under Shift-lever ≥ (350±50ms) in R position and IGN SW DDM = IGN ON and Current Vertical AD> VvReverse min.
        3. IGN SW DDM changes to IGN ON from (ACC Key In or Key Off), under Shift-lever ≥ (350±50ms) in R position and mirror select switch is in NOT NEUTRAL and Current Vertical AD> VvReverse min.
      2. In the MOVING DOWN or DOWN state mentioned above,
        1. DDM starts returning to previous position when one of the following conditions is satisfied.
          • Shift-lever is NOT R position.
          • Mirror select switch = NEUTRAL.
          • IGN SW DDM = (Key Off, Key In or ACC).
        2. DDM stops reverse down immediately if Manual function is operate by user. After this, mirror will go back previous position if above condition (a) is satisfied.
        3. DDM stops reverse down if mirror position reached to target position or position not reached after 40s±1s.
      3. In the RETURING state mentioned above,
        1. DDM stops returning if mirror position reached to previous position or position not reached after 40s±1s.
        2. DDM stops moving immediately if Manual function is operate by user. And mirror moves according to the manual switch operation.
        3. DDM stops returning if IGN SW DDM changes to IGN ON and select switch is not neutral, then check Shift-lever for 1 sec. However one of following condition is satisfied in STOP CHECKING SHIFT LEVER. DDM goes previous position again immediately.
        • Mirror select switch is NEUTRAL.
        • IGN SW DDM = (Key Off, Key In or ACC).
        • Exceeded 1 sec in STOP CHECKING SHIFT LEVER and Shift-lever is NOT R position.
    6. Arbitration Control

      IMS function is carried out according to the following priority table. If IMS requirement happen same time.

      *1: This is impossible because playback by P1/P2 switch will be carried out under P position, and Auto Reverse is carried out under R position.
