OPERATION EXPLANATION
The reverse position signal is sent from the shift position switch to the parking assist ECU when the shift position is moved to R.
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.
The steering angle sensor signal is used to control parking assist only for estimated guide line mode.
COMMUNICATION SYSTEM OUTLINE
CAN communication system
The panoramic view monitor system uses CAN communication for data communications between the parking assist ECU and each ECU.
If a problem occurs in the CAN communication line, the parking assist ECU outputs a CAN communication malfunction DTC. (To check, use the GTS.)
When there is a problem with the CAN communication line, the parking assist ECU stores a CAN communication malfunction DTC. (Perform a check of the radio and display receiver assembly using the diagnosis screen)
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.
Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
VIDEO SIGNALS
Video signal circuit
Video signals from each camera are input into the parking assist ECU via GVIF cable.
Video signals from the parking assist ECU are input into the radio and display receiver assembly via GVIF cable.
Screen display
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.
DIAGNOSTIC FUNCTION OUTLINE
This panoramic view monitor system has a diagnostic function displayed in the radio and display receiver assembly. This function enables the calibration (adjustment and verification) of the panoramic view monitor system.
The panoramic view monitor system has a diagnosis function which can check each signal input to the parking assist ECU and adjust and monitor the panoramic view monitor system.
The panoramic view monitor system can check the following items by using the GTS.
