PARKING ASSIST MONITOR SYSTEM > SYSTEM DESCRIPTION

for Preparation Click here

1. This system has a rear television camera assembly mounted on the back door to display the rear view of the vehicle on the multi-display. 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 behind the vehicle.
   

2. This system consists of the following components:
   
   

   1. Parking assist ECU
      

   2. Rear television camera assembly
      

   3. Multi-display
      

   4. Display and navigation module display*1
      

   5. Navigation computer sub-assembly*2
      

   6. Power management control ECU
      

   7. Skid control ECU
      

   8. Spiral with sensor cable sub-assembly
      

      1. *1: w/ Navigation System (for DVD)
         
      2. *2: w/ Navigation System (for HDD)
         

3. This system is equipped with a self-diagnosis system, which is operated on a designated window that appears on the display panel, just as in the navigation system.
   

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

   Item	Function
   Rear Television Camera Assembly	Mounted on the back door to transmit an image of the area behind the vehicle to the parking assist ECU. Has a color video camera that uses a Charge Coupled Device (CCD) and a wide-angle lens.
   Parking Assist ECU	Transmits video signals, which contain a composite consisting of an image of the area behind the vehicle taken with the television camera and parking assist guidelines, to the multi-display. Performs overall control of the system by receiving signals from the sensors.
   Multi-display	Receives the video signals containing a composite of an image of the area behind the vehicle and parking assist guideline signals from the parking assist ECU, and displays them on the display panel.
   Display and Navigation Module Display*1 Navigation Computer Sub-assembly*2	Uses the yaw rate detected by the gyro sensor that is built into the display and navigation module display*1 or navigation computer sub-assembly*2 to transmit the movement of the vehicle to the parking assist ECU. Sends the shift state signal to the parking assist ECU through the AVC-LAN.
   Spiral with Sensor Cable Sub-assembly	Detects the angle of the steering wheel and sends the resulting signals to the parking assist ECU through CAN communication.
   Power Management Control ECU	Sends the shift state signal to the display and navigation module display*1 or navigation computer sub-assembly*2 through CAN communication.
   Skid control ECU	Transmits a vehicle speed signal to the parking assist ECU.

   1. *1: w/ Navigation System (for DVD)
      
   2. *2: w/ Navigation System (for HDD)
      

1. The reverse signal is sent to the display and navigation module display*1 or navigation computer sub-assembly*2 when the shift lever is moved to R.
   After receiving the reverse position signal, the display and navigation module display*1 or navigation computer sub-assembly*2 switches the display signal for the multi-display from the navigation system to the parking assist monitor system.
   

   1. *1: w/ Navigation System (for DVD)
      
   2. *2: w/ Navigation System (for HDD)
      

2. In parallel parking assist mode, 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.
   

   HINT:

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

1. While the parking assist monitor is displayed, pressing the line mode button switches the parking assist monitor display mode.

1. The components of the parking assist monitor system communicate with each other through the AVC-LAN. Also, parallel parking assist mode judges the vehicle angle data transmitted via the AVC-LAN from the display and navigation module display*1 or navigation computer sub-assembly*2 (the data is calculated by the display and navigation module display*1 or navigation computer sub-assembly*2 by integrating the yaw rate of the gyro sensor built into the display and navigation module display*1 or navigation computer sub-assembly*2).
   

   1. *1: w/ Navigation System (for DVD)
      
   2. *2: w/ Navigation System (for HDD)
      

2. If a short circuit or open circuit occurs in the AVC-LAN, communication is interrupted and the parking assist monitor system will stop functioning.
   

1. This parking assist monitor system has a diagnostic function displayed in the multi-display. This function enables calibration (adjustment and verify) of the parking assist monitor system (Click here).
