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


  1. *1: for Navigation Receiver Type
  2. *2: for Radio and Display Type

GENERAL

  1. This system has a rear television camera assembly mounted on the back door to display the rear view of the vehicle on the multi-display (display panel). The display panel also shows a composite view consisting of the area behind the vehicle and parking guidelines to assist the driver in parking the vehicle by monitoring the area behind the vehicle.

  2. This system consists of the following components:

    1. Parking assist ECU

    2. Rear television camera assembly

    3. Navigation receiver assembly*1

    4. Radio and display receiver assembly*2

    5. Spiral cable sub-assembly

    6. Skid control ECU (brake actuator assembly)

    7. ECM

    8. Main body ECU (multiplex network body ECU)

    9. Four wheel drive control ECU

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


FUNCTION OF COMPONENTS

  1. The parking assist ECU controls the system by using information from the following components.

    Item
    		Function
    Rear Television Camera Assembly
    1. Mounted on the back door to transmit the rear view of the vehicle to the parking assist ECU.
    2. Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and a wide-angle lens.
    Parking Assist ECU
    1. Receives video signals, which contain an image of the area behind the vehicle taken with the rear television camera assembly.
    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.
    Navigation Receiver Assembly*1
    Radio and Display Receiver Assembly*2
    		Receives the video signals containing a composite of the rear view of the vehicle and parking assist guideline signals from the parking assist ECU, and sends them on the multi-display (display panel).
    Spiral Cable Sub-assembly
    		Detects the angle of the steering wheel and sends the resulting signals to the parking assist ECU through CAN communication.
    Skid Control ECU (Brake Actuator Assembly)
    		Sends the inner brake information and ABS ACT information to the parking assist ECU through CAN communication.
    Four Wheel Drive Control ECU
    		Sends the L4 condition signal to the parking assist ECU through CAN communication.
    ECM
    		Sends the vehicle condition, 2WD/4WD information and shift position information to the parking assist ECU through CAN communication.
    Main Body ECU (Multiplex Network Body ECU)
    		Sends the back door courtesy light switch signal to the parking assist ECU through CAN communication.

OPERATION EXPLANATION

  1. The reverse position signal is sent from the shift lever position switch to the parking assist ECU when the shift lever is moved to R.

  2. In parallel parking assist mode, an appropriate steering angle and timing information can be provided for the driver. This is based on the information from the steering angle sensor signal and the vehicle angle data signal that are sent to the parking assist ECU.

    HINT:
    The steering angle sensor signal is used to control parking assist for only estimated guide line mode.

COMMUNICATION SYSTEM OUTLINE

  1. The components of the parking assist monitor system communicate with each other through the AVC-LAN. Also, parallel parking assist mode judges the vehicle angle data transmitted via the AVC-LAN from the navigation receiver assembly*1 or radio and display receiver assembly*2 (the data is calculated by the navigation receiver assembly*1 or radio and display receiver assembly*2 by integrating the yaw rate of the gyro sensor built into the navigation receiver assembly*1 or radio and display receiver assembly*2).

  2. If a short circuit or open circuit occurs in the AVC-LAN, communication is interrupted and the parking assist monitor system will stop functioning.


DIAGNOSTIC FUNCTION OUTLINE

  1. This parking assist monitor system has a diagnostic function displayed in the navigation receiver assembly*1 or radio and display receiver assembly*2. This function enables the calibration (adjustment and verification) of the parking assist monitor system (LandCruiser RM000003WVZ06KX.html).

  2. The parking assist monitor system can check the following items by using the GTS.
