PARKING ASSIST MONITOR SYSTEM SYSTEM DESCRIPTION

  1. GENERAL

    1. This system has a 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. Television camera assembly

      2. Navigation ECU sub-assembly

      3. Spiral with sensor cable sub-assembly

      4. Brake actuator assembly

      5. Main body ECU (multiplex network body ECU)

      6. Back door lock assembly

      7. Back-up light switch assembly (for Manual Transaxle)

      8. Pack/neutral position switch assembly (except Manual Transaxle)

    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.

  2. FUNCTION OF COMPONENTS

    1. The navigation ECU sub-assembly controls the system by using information from the following components.

      Item

      Function

      Television Camera Assembly

      • Mounted on the back door to transmit an image of the area behind the vehicle to the radio and display receiver assembly.

      • Has a color video camera that uses a Complementary Metal Oxide Semiconductor (CMOS) and a wide-angle lens.

      Navigation ECU Sub-assembly

      • Receives video signals, which contain an image of the area behind the vehicle taken with the television camera assembly.

      • Performs overall control of the system by receiving signals from the sensors.

      • Creates images and displays adjustment screens performed on the diagnosis screen.

      • Stops displaying the guide lines and buttons and displays "Check surrounding for safety" when an open signal is received for the back door.

      • Displays "Back door is open" on the back camera position setting screen when an open signal is received for the back door.

      Spiral with Sensor Cable Sub-assembly

      Detects the angle of the steering wheel and sends the resulting signals to the navigation ECU sub-assembly through CAN communication.

      Brake Actuator Assembly

      Transmits a vehicle speed signal to the navigation ECU sub-assembly through CAN communication.

      Main Body ECU (Multiplex Network Body ECU)

      Transmits a back door courtesy switch signal to the navigation ECU sub-assembly through CAN communication.

      Back Door Lock Assembly

      Transmits a back door courtesy switch signal to the main body ECU (multiplex network body ECU) through CAN communication.

      Park/Neutral Position Switch Assembly*1

      Back-up Light Switch Assembly*2

      Sends the shift position signal to the navigation ECU sub-assembly.

      • *1: except Manual Transaxle

      • *2: for Manual Transaxle

  3. OPERATION EXPLANATION

    1. The navigation ECU sub-assembly receives the reverse signal via a CAN communication line when the ignition switch is ON and the shift lever is moved to R. After receiving the reverse signal, the navigation ECU sub-assembly switches to the parking assist monitor system.
