Side Monitor System -- System Description |
- *1: for Navigation Receiver Type
- *2: for Radio and Display Type
GENERAL |
This system has a side television camera assembly built into the outer rear view mirror assembly (passenger side and driver side) to display the passenger side and driver side views of the vehicle on the multi-display (display panel).
This system consists of the following components:
Outer rear view mirror assembly
Side television camera assembly
Parking assist ECU
Navigation receiver assembly*1
Radio and display receiver assembly*2
Skid control ECU (brake actuator assembly)
Spiral cable sub-assembly
Outer mirror switch assembly
Four wheel drive control ECU
ECM
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.
FUNCTION OF COMPONENTS |
The parking assist ECU controls the system by using information from the following components.
Item Function Parking Assist ECU - Turns the side 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.
- Transmits 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 wide view front and side monitor 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 multi-display (display panel).
- With the video feed from the side television camera assembly showing the vehicle's left-side surroundings as a base, uses vehicle information such as the signal from the steering angle sensor to calculate and overlay a composite image and output this to the screen of the multi-display (display panel).
- Renders each configuration page in the diagnosis window and outputs the screen to the multi-display (display panel).
- When the outer mirror retraction signal is received, terminates the side camera collimation/alignment.
- Stores each configuration setting from the diagnosis window.
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.
Side television camera assembly Generates a video feed showing the passenger 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. Outer Mirror Switch Assembly Transmits outer mirror retraction signal to parking assist ECU. Spiral Cable Sub-assembly Transmits steering angle signal and sensor status signal to multi-display via 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. Main Body ECU (Multiplex Network Body ECU) Sends the back door courtesy light switch signal to the parking assist ECU through CAN communication. - Turns the side 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.
OPERATION EXPLANATION |
The wide view front and side monitor switch ON signal is sent from the main switch to the parking assist ECU.
After receiving the wide view front and side monitor switch ON signal, the parking assist ECU switches the display signal for the navigation receiver assembly*1 or radio and display receiver assembly*2 to the side monitor system.
