Parking Assist Monitor System (W/O Side Monitor System) -- System Description



GENERAL

  1. This system has a rear television camera assembly mounted on the back door to display an image of the area behind the vehicle on the display. The display panel also shows a composite view consisting of the area behind the vehicle and parking guide lines to assist the driver in parking the vehicle by monitoring the area behind the vehicle.

  2. This system consists of the following components:

    1. Multi-media module receiver assembly

    2. Rear television camera assembly

    3. Clearance warning ECU assembly

    4. Steering sensor

    5. Master cylinder solenoid (skid control ECU assembly)

    6. Steering control ECU*

    7. Main body ECU (cowl side junction block LH)

    8. Park/neutral position switch assembly

    9. Multi-display assembly

    10. Speaker

      1. *: w/ Variable Gear Ratio Steering System

  3. This system is equipped with a self-diagnosis system, which is operated on a designated window that appears on the display panel, just as in the navigation system.


FUNCTION OF COMPONENTS

  1. The multi-media module receiver assembly controls the system by using information from the following components.

    Item
    		Function
    Rear Television Camera Assembly
    1. Mounted on the back door to transmit an image of the area behind the vehicle to the multi-media module receiver assembly.
    2. Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and a wide-angle lens.
    Multi-media Module Receiver Assembly
    1. Receives video signals, which contain an image of the area behind the vehicle taken with the rear television camera assembly, and sends them on the multi-display assembly (display panel)..
    2. Performs overall control of the system by receiving signals from the sensors.
    3. Allows operation via the touch panel of the display when the park assist monitor screen or diagnosis screen is displayed.
    4. Creates images and displays adjustment screens performed on the diagnosis screen.
    5. Stops displaying the guide line and buttons displays "Check surrounding for safety" when an open signal is received for the back door.
    6. Displays "Back door is open" on the back camera position setting screen when an open signal is received for the back door.
    Park/Neutral Position Switch Assembly
    		Sends the reverse signal to the multi-media module receiver assembly.
    Clearance Warning ECU Assembly
    		Sends the clearance detection information to the multi-media module receiver assembly through CAN communication.
    Steering Sensor
    		Detects the angle of the steering wheel and sends the resulting signals to the multi-media module receiver assembly through CAN communication.
    Master Cylinder Solenoid (Skid Control ECU Assembly)
    		Transmits a vehicle speed signal to the multi-media module receiver assembly through CAN communication.
    Steering Control ECU*
    		Sends the VGRS relative angle to the multi-media module receiver assembly through CAN communication.
    Main Body ECU (Cowl Side Junction Block LH)
    		Transmits a back door courtesy light switch signal to the multi-media module receiver assembly through CAN communication.
    1. *: w/ Variable Gear Ratio Steering System

OPERATION EXPLANATION

  1. The multi-media module receiver assembly receives the reverse signal via CAN communication line when the engine switch on (IG) and the shift lever is moved to R. After receiving the reverse signal, the multi-media module receiver assembly switches from the navigation system to parking assist monitor system (w/o Side Monitor System).
