PARKING ASSIST MONITOR SYSTEM(w/o Parallel Parking Assist Function) SYSTEM DESCRIPTION


  1. 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 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. Rear television camera assembly

      2. Radio receiver assembly

      3. Multi-display assembly

      4. Spiral cable with sensor sub-assembly

      5. Power management control ECU

      6. Main body ECU (multiplex network body ECU)

      7. Brake booster with master cylinder assembly (skid control ECU)

      8. Clearance warning ECU assembly*1


        • *1: w/ LEXUS 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 rear television camera assembly controls the system by using information from the following components.

      Item Function
      Rear 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 radio receiver assembly.

      • 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.
      Multi-display 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.
      Radio Receiver Assembly

      • 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.

      • Performs control of the system by receiving the reverse signal from the power management control ECU via CAN communication.

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

      • Receives diagnostic mode video signals from the rear television camera assembly.
      Spiral Cable with Sensor Sub-assembly Detects the angle of the steering wheel and transmits the resulting signals to the rear television camera assembly via CAN communication.
      Power Management Control ECU Transmits a reverse signal to the rear television camera assembly and radio receiver assembly via CAN communication.
      Brake Booster with Master Cylinder Assembly (Skid Control ECU) Transmits a vehicle speed signal to the rear television camera assembly via CAN communication.
      Main Body ECU (Multiplex Network Body ECU)

      • Transmits a back door courtesy switch signal to the rear television camera assembly via CAN communication.

      • Transmits a vehicle information signal to the rear television camera assembly via CAN communication.
      Clearance Warning ECU Assembly*1 Transmits a sonar information signal to the rear television camera assembly via CAN communication.

      • *1: w/ LEXUS Parking Assist-sensor System

  3. OPERATION EXPLANATION


    1. The radio receiver assembly receives the reverse signal when the power switch is on (IG) and reverse (R) is selected. After receiving the reverse signal, the multi-display switches to the parking assist monitor system.
