Parking Assist Monitor System (For Camera Built-In Ecu) -- System Description


  1. *1: for Navigation Receiver Type
  2. *2: for Radio and Display Type
  3. *3: w/ TOYOTA Parking Assist-sensor System

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 navigation receiver assembly*1 or radio and display receiver assembly*2. The navigation receiver assembly*1 or radio and display receiver assembly*2 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. Rear television camera assembly

    2. Navigation receiver assembly*1

    3. Radio and display receiver assembly*2

    4. Spiral with sensor cable sub-assembly

    5. Main body ECU (multiplex network body ECU)

    6. ECM

    7. Clearance warning ECU assembly*3

  3. This system is equipped with a self-diagnosis system, which is operated from a designated window that appears on the navigation receiver assembly*1 or radio and display receiver assembly*2.


FUNCTION OF COMPONENTS

  1. The rear television camera 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 a composite image of the area behind the vehicle and guide lines calculated based on signals received from each ECU, to the navigation receiver assembly*1 or radio and display receiver assembly*2.
    2. Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and wide-angle lens.
    3. Stops displaying the guide lines when an open signal is received for the back door.
    4. Performs overall control of the system by receiving signals from the sensor and ECUs.
    5. Creates images and displays adjustment screens performed on the diagnosis screen.
    6. Displays "Back door is open. Do not use the rear view monitor when the back door is not completely closed." on the back camera position setting screen when the back door is open.
    Navigation Receiver Assembly*1 or Radio and Display Receiver Assembly*2
    		Receives video signals which contain a composite image of the area behind the vehicle taken with the rear television camera assembly and guide lines calculated based on signals received from each ECU.
    Spiral with Sensor Cable Sub-assembly
    		Detects the angle of the steering wheel and transmits the resulting signals to the rear television camera assembly via CAN communication.
    ECM
    		Transmits a shift position signal to the rear television camera assembly via CAN communication.
    Main Body ECU (Multiplex Network Body ECU)
    		Transmits a back door courtesy switch signal, engine switch signal, time stamp signal, handle signal and destination signal to the rear television camera assembly via CAN communication.
    Clearance Warning ECU Assembly*3
    		Transmits a sonar information signal to the rear television camera assembly via CAN communication.

OPERATION EXPLANATION

  1. The television camera assembly sends the display signal to the navigation receiver assembly*1 or radio and display receiver assembly*2. The navigation receiver assembly*1 or radio and display receiver assembly*2 receives the reverse signal via a CAN communication line when the engine switch is on (IG) and the shift lever is moved to R. After receiving the reverse signal, the navigation receiver assembly*1 or radio and display receiver assembly*2 switches to the parking assist monitor system.
