PANORAMIC VIEW MONITOR SYSTEM SYSTEM DESCRIPTION

GENERAL

1. This system has front, front passenger side, driver side and rear television camera assemblies mounted around the vehicle to display around the vehicle on the radio and display receiver assembly. The display panel also shows a composite view consisting of the area behind the vehicle and parking guidelines to assist the driver in parking the vehicle by monitoring the area around the vehicle.

2. This system consists of the following components:

   1. Parking assist ECU

   2. Telltale light assembly (panoramic view monitor main switch)

   3. Rear television camera assembly

   4. Front television camera assembly

   5. Side television camera assembly LH

   6. Side television camera assembly RH

   7. Radio and display receiver assembly

   8. Spiral with sensor cable sub-assembly

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

   10. Main body ECU (multiplex network body ECU)

   11. Clearance warning ECU assembly

   12. Hybrid vehicle control ECU

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 or audio and visual system.

OPERATION EXPLANATION

1. The reverse position signal is sent from the shift lever position switch to the parking assist ECU when the shift lever is moved to R.

2. An appropriate steering angle and timing information can be provided for the driver. This is based on the information from the steering angle sensor signal and the vehicle angle data signal that are sent to the parking assist ECU.

   Tip:

   The steering angle sensor signal is used to control parking assist only for estimated guide line mode.

COMMUNICATION SYSTEM OUTLINE

1. CAN communication system

   1. The panoramic view monitor system uses CAN communication for data communications between the parking assist ECU and each ECU.

   2. If a problem occurs in the CAN communication line, the parking assist ECU outputs a CAN communication malfunction DTC. (To check, use the GTS.)

      Click here

   3. If a problem occurs in the CAN communication line, the parking assist ECU outputs a CAN communication malfunction DTC. (To check, use the multi-display diagnosis screen.)

      Click here

   4. If a CAN communication line malfunction DTC is output, repair the malfunction in the communication line and troubleshoot the panoramic view monitor system when data communication is normal.

   5. Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.

2. AVC-LAN communication system

   

   1. The panoramic view monitor system uses the AVC-LAN to communicate with other equipment.

   2. The master device for the AVC-LAN is the radio and display receiver assembly.

   3. Resistance necessary for communication transfer (60 to 80 Ω between the TX+ - TX- terminals) is inside the radio and display receiver assembly.

   4. If a malfunction such as a communication line short, +B short, or GND short occurs in the AVC-LAN circuit, communication is interrupted and the panoramic view monitor system and navigation system*1 or audio and visual system (for radi oand display type)*2 do not operate normally.

      • *1: w/ Navigation System

      • *2: w/ Audio and Visual System (for Radio and Display Type)

VIDEO SIGNALS

1. Video signal circuit

   

   1. Video signals from the front television camera assembly are input into the parking assist ECU via analog communication lines (vehicle wire harness).

   2. Video signals from the side television camera assembly LH are input into the parking assist ECU via analog communication lines (vehicle wire harness).

   3. Video signals from the side television camera assembly RH are input into the parking assist ECU via analog communication lines (vehicle wire harness).

   4. Video signals from the rear television camera assembly are input into the parking assist ECU via analog communication lines (vehicle wire harness).

   5. Video signals from the parking assist ECU are input into the radio and display receiver assembly via AVC-LAN communication lines.

2. Screen display

   1. Video signals input from each camera are processed in the parking assist ECU and displayed on the radio and display receiver assembly as the panoramic view monitor system screen.
