SYSTEM DESCRIPTION

1. GENERAL

(a) 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 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 behind the vehicle.

(b) This system consists of the following components:

(1) Parking assist ECU

(2) Rear television camera assembly

(3) Multi-display assembly

(4) Display and navigation module display

(5) Power management control ECU

(6) Combination meter assembly

(7) Spiral with sensor cable sub-assembly

(c) 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.

2. FUNCTION OF COMPONENTS

(a) The parking assist ECU controls the system by using information from the following components.





3. OPERATION EXPLANATION

(a) 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.

After receiving the reverse position signal, the parking assist ECU switches the display signal for the multi-display from the navigation system to the parking assist monitor system.

(b) 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 for only estimated guide line mode.

4. DISPLAY MODE SETTING





(a) While the parking assist monitor is displayed, pressing the line mode button switches the parking assist monitor display mode.

5. COMMUNICATION SYSTEM OUTLINE

(a) 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 (the data is calculated by the display and navigation module display by integrating the yaw rate of the gyro sensor built into the display and navigation module display).

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

6. DIAGNOSTIC FUNCTION OUTLINE

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

(b) The parking assist monitor system can check the following items by using the Techstream.
