  2. FUNCTION OF COMPONENTS


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

      Item Function
      Front Television Camera Assembly Generates a video feed showing the front side of the vehicle and transmits the video to the parking assist ECU.
      Steering Pad Switch Assembly (Wide View Front and Side Monitor Switch) Operating the switch sends a signal to the parking assist ECU.
      Parking Assist ECU

      • Turns the front television camera assembly on or off based on parameters such as the display settings, the wide view front and side monitor switch signal, the shift signal and the vehicle speed signal.

      • Display the wide view front and side monitor, side monitor, or wide view front monitor signals to the navigation receiver assembly*1 or radio and display receiver assembly*2 based on parameters such as the display settings, the front and side monitor main switch signal, the shift signal and the vehicle speed signal.

      • Depending on the display settings, renders the output display for the wide view front and side monitor, the side monitor, or the wide view front monitor, and outputs them to the screen of the navigation receiver assembly*1 or radio and display receiver assembly*2.

      • Renders each configuration page in the diagnosis window and outputs the screen to the navigation receiver assembly*1 or radio and display receiver assembly*2.

      Navigation Receiver Assembly*1

      Radio and Display Receiver Assembly*2

      • Communicates with the parking assist ECU through AVC-LAN communication.

      • This touch panel display is used to view and interact with the wide view front and side monitor, side view monitor, wide view front monitor, and diagnosis screens.
      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.

  3. OPERATION EXPLANATION


    1. The front and side monitor main switch ON signal is sent from the main switch to the parking assist ECU.

      After receiving the front and side monitor main switch ON signal, the parking assist ECU switches the display signal to the wide view front monitor system.
