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

GENERAL

1. This system has a rear television camera assembly mounted on the luggage compartment door to display an image of the area behind the vehicle on the multi-display assembly. The multi-display assembly 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. Luggage electrical key switch

   3. Radio receiver assembly

   4. Multi-display assembly

   5. Spiral cable with sensor sub-assembly

   6. Hybrid vehicle control ECU assembly

   7. Main body ECU (multiplex network body ECU)

   8. Blind spot monitor sensor LH*1

   9. Clearance warning ECU assembly*2

      
      

      • *1: w/ Blind Spot Monitor System

      • *2: 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 assembly.

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 luggage compartment 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 multi-display 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 luggage compartment door. Performs overall control of the system by receiving signals from the sensor and ECUs.
   Multi-display 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 BKUP LP relay. Receives diagnostic mode video signals from the rear television camera assembly. Displays "You can not calibrate the camera when the door is open. Please close the door." on the back camera position setting screen when the luggage compartment door is open.
   Radio Receiver Assembly	Transmits a setting information signal to the rear television camera assembly via CAN communication.
   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.
   Hybrid Vehicle Control ECU Assembly	Transmits the vehicle information signal to the rear television camera assembly via CAN communication. Transmits the reverse signal to the multi-display assembly and the radio receiver assembly via CAN communication.
   Main Body ECU (Multiplex Network Body ECU)	Transmits the luggage compartment door courtesy switch signal and vehicle information signal to the rear television camera assembly and the radio receiver assembly via CAN communication.
   Blind Spot Monitor Sensor LH*1	Transmits the RCTA information signal to the rear television camera assembly via CAN communication.
   Clearance Warning ECU Assembly*2	Transmits the sonar information signal to the rear television camera assembly via CAN communication.

   
   

   • *1: w/ Blind Spot Monitor System

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

OPERATION EXPLANATION

1. Operation description of the park assist monitor system

   
   

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