PARKING ASSIST MONITOR SYSTEM


  1. FUNCTION OF MAIN COMPONENTS

    Component Function
    Rear Television Camera Assembly

    • Captures images of the area behind the vehicle and outputs visual signals to the parking assist ECU*1 and the navigation receiver assembly*2 or radio and display receiver assembly*3.

    • The parking assist guide lines that are calculated based on signals from the steering sensor are superimposed on the captured image. Then, the image is sent to the navigation receiver assembly*2 or radio and display receiver assembly*3 as video signals.*4

    • When the back door is open, superimposing of parking assist guide lines is canceled and only the captured image is sent as video signals.*4
    Navigation Receiver Assembly*2 or Radio and Display Receiver Assembly*3 Displays images of the area behind the vehicle sent from the rear television camera assembly using the multi-display. The image is combined with the parking assist guide lines that are calculated based on signals from the steering angle sensor.*5
    Multi-display Receives visual signals composed of the area behind the vehicle with parking assist guide lines overlaid from the navigation receiver assembly*2 or radio and display receiver assembly*3, and displays them on the multi-display.
    Skid Control ECU Transmits received vehicle speed signals to the navigation receiver assembly*2 or radio and display receiver assembly*3.
    Steering Angle Sensor Detects the steering angle and transmits signals to the navigation receiver assembly*2 or radio and display receiver assembly*3.
    Park/Neutral Position Switch Assembly*6 Transmits a signal telling the ECM or TCM*7 that the shift lever is in R.
    Back-up Light Switch Assembly*8 Transmits a signal telling the ECM that the shift lever is in R.
    ECM Sends received shift position signals to the navigation receiver assembly*2 or radio and display receiver assembly*3.
    Clearance Warning ECU Assembly*9 Sends clearance sonar detection information to the navigation receiver assembly*2 or radio and display receiver assembly*3.
    Main Body ECU (Driver Side Junction Block Assembly) Outputs the back door courtesy switch signal to the navigation receiver assembly*2 or radio and display receiver assembly*3.
    Parking Assist ECU Outputs the signal of the rear television camera assembly to the navigation receiver assembly*2 or radio and display receiver assembly*3.
    TCM*7 Sends received shift position signals to the ECM.

      1. Perpendicular Parking Mode


        • Perpendicular parking mode consists of A: parking assist guide line display mode, B: course line deletion mode and C: estimated course line display mode. The initial (default) setting for perpendicular parking is estimated course line display mode.

        • Pressing the display mode switch screen button switches among the rear monitor modes. (Models with parallel parking assist mode)

        • When perpendicular parking mode is operating, fixed guide lines appear superimposed on a view of the area behind the vehicle. These guide lines can be used to assist the driver while backing up the vehicle.

        1. Select parking assist guide line display mode (Models without parallel assist parking assist mode)

        2. Move the shift lever to R.

        3. Select perpendicular parking mode. (Models with parallel assist parking assist mode)

        4. Select parking assist guide line display mode. (Models with parallel assist parking assist mode)

        5. An image appears on the display panel as illustrated below:

          A01UL0G

        6. Back the vehicle up and stop at the position in which the parking assist guide line comes in contact with the left side of the intended parking position.

        7. Turn the steering wheel fully to the right and back the vehicle up.

          A01UL3X

        8. Continue backing the vehicle up until the vehicle is parallel to the plotted lines.

        9. Once the vehicle is parallel, aim the steering wheel straight ahead and back the vehicle up to the target stop position.

    2. Estimated Course Line Display Mode (Perpendicular Parking) of Parking Assist Monitor System


      1. To use estimated course line display mode in perpendicular parking when parking the vehicle in a parking space, perform the following procedure:


        1. Select estimated course line display mode. (Models without parallel assist parking assist mode)

        2. Move the shift lever to R.

        3. Select perpendicular parking mode. (Models with parallel assist parking assist mode)

        4. Select estimated course line display mode.

        5. An image appears on the display panel as illustrated below:

          A01UKLK

        6. Turn the steering wheel so that the estimated course lines are within the parking space, and back up carefully.

          A01UKKM

        7. When the rear of the vehicle is within the parking space, turn the steering wheel in order to equalize the left and right intervals between the vehicle width extension lines and the parking space sidelines.

        8. When the vehicle width extension guide lines and the parking space sidelines are parallel, straighten the steering wheel and then carefully back up until the entire vehicle is within the parking space.

    3. Parallel Parking Assist Mode of Parking Assist Monitor System (Models with Parallel Parking Assist Mode)


      1. To use parallel parking assist mode to park the vehicle in the parking space, perform the following procedure:


        • Stop the vehicle parallel to the road or the curb, at a side-to-side clearance of approximately 1.0 m (3.3 ft.) from the parked vehicle, approximately one-half car length forward of the parked vehicle.

          Text in Illustration
          *a Approx. 1.0 m (3.3 ft.) *b Target Parking Position

        • Aim the steering wheel straight ahead and move the shift lever to R.

        • Select parallel parking assist mode.

        • An image is shown on the display panel as illustrated below:

          A01UKZT

        • Drive the vehicle straight back and stop when the black and yellow vertical pole of the target parking position is aligned with the rear end of the parked vehicle.

          Text in Illustration
          *a Black and Yellow Vertical Pole - -

        • When the steering wheel is turned, the blue outline appears. At this time, the blue vertical line opposite to the target parking position disappears when the steering wheel is turned.

          A01UKLCE03
          Text in Illustration
          *a Blue Outline - -

        • Continue turning the steering wheel, and the blue outline moves in the direction of the target parking position, while the outline changes into a shape as illustrated below. Keep turning the steering wheel until the blue outline reaches the target parking position.

          A01UKHAE02
          Text in Illustration
          *a Blue Outline - -

        • However, if the steering wheel is turned too much, the message as shown in the illustration below is displayed and the blue outline changes to red to inform the driver that the assist operation is not possible. Also, when the vehicle is too far away from the shoulder, the same condition occurs even when adjusting the blue outline to a normal position.

          A01UKN9E03
          Text in Illustration
          *a Outline Change from Blue to Red - -

        • The vertical line (blue) and target frame (blue) disappear and the parking guide lines appear on the target parking position.

          *a Curved Blue Line (Blue) - -

        • Keep the steering wheel in the same position and back up. Stop when the parking guide line reaches the right end of the target parking position.

          A01UKLV

        • With the vehicle at a standstill, fully turn the steering wheel in the opposite direction.

          A01UL3J

        • Using the distance guide line, slowly back the vehicle up until the vehicle is parallel to the road or curb, while paying attention to the vehicles in front and in back. The parking maneuver is completed once the vehicle is parallel.
