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 multi-display. The multi-display 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 receiver assembly*1

      3. Radio and display receiver assembly*2

      4. Steering sensor

      5. ECM

      6. Main body ECU (multiplex network body ECU)

      7. Brake actuator assembly (skid control ECU)

      8. Power steering ECU assembly

      9. Clearance warning ECU assembly*3

      10. BACK UP LP relay


        • *1: for Navigation Receiver Type

        • *2: for Radio and Display Type

        • *3: w/ Toyota Parking Assist-sensor System

    3. This system is equipped with a self-diagnosis system, which is operated on a designated window that appears on the multi-display.

  2. FUNCTION OF COMPONENTS


    1. The television camera assembly controls the system by using information from the following components.

      Item Function
      Television Camera Assembly

      • 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.

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

      • Stops displaying the guide lines when an open signal is received for the back door.

      • Performs overall control of the system by receiving signals from the sensor and ECUs.

      • Navigation Receiver Assembly*1

      • Radio and Display Receiver Assembly*2

      • Receives video signals which contain a composite image of the area behind the vehicle taken with the television camera assembly and guide lines calculated based on signals received from each ECU.

      • Performs control of the system by receiving the reverse signal from the BACK UP LP relay.

      • Transmits a setting information signal to the television camera assembly via CAN communication.

      • Receives diagnostic mode video signals from the television camera assembly.

      • 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.
      Steering Sensor Detects the angle of the steering wheel and transmits the resulting signals to the television camera assembly via CAN communication.
      ECM

      • Transmits a vehicle information signal to the television camera assembly via CAN communication.

      • Transmits a reverse signal to the television camera assembly via CAN communication.

      Brake Actuator Assembly

      - Skid Control ECU

      		 Transmits a vehicle speed signal to the television camera assembly via CAN communication.
      Main Body ECU (Multiplex Network Body ECU) Transmits a back door courtesy switch signal to the television camera assembly via CAN communication.
      Power Steering ECU Assembly Transmits an EPS variation signal to the television camera assembly via CAN communication.
      Clearance Warning ECU Assembly*3 Transmits a sonar information signal to the television camera assembly via CAN communication.
      BACK UP LP Relay Transmits a reverse signal to the navigation receiver assembly*1 or radio and display receiver assembly*2.

      *1: for Navigation Receiver Type

      *2: for Radio and Display Type

      *3: w/ Toyota Parking Assist-sensor System

  3. OPERATION EXPLANATION


    1. The navigation receiver assembly*1 or radio and display receiver assembly*2 receives the reverse signal when the engine switch is on (IG) and the shift lever is moved to R. After receiving the reverse signal, the multi-display switches to the parking assist monitor system.
