SVM System Input/Output
- Camera input
Item Specification Lens angle of view 190 degrees Angle of view Horizontal 186 degrees Vertical 135 degrees Function Provides the original image of the wide angle image (no additional function) Application location Same camera applied to the front, rear, left and right - SVM image output
The SVM unit carries out distortion compensation and video merging on the image from 4 cameras installed around the vehicle, indicates steering interlocking guidelines and others, and outputs them in analog.
- SVM switch
When the switch is ON, this is used as a control input signal that operates the front view mode.
- Ignition input
The SVM unit outputs images only when IGN2 ON. When IGN2 OFF, it is an SVM OFF state, and limits image outputting. SVM unit uses signals inputted through IGN pin or M_CAN communication to determine whether IGN2 is ON or OFF.
- Output switch indicator lamp
SVM units output power through PWM waves from the LED located in the SVM switch to show the user whether the switch has been pressed.
- Input chassis CAN (C_CAN)
The SVM unit uses C_CAN to receive information about the vehicle's condition and to decide whether to carry out main SVM operations.
- Multimedia CAN input/output (M_CAN)
M-CAN signal is changed to C-CAN signal by IGPM (routing function or central gateway) and then SVM unit can use this C-CAN signal.
M_CAN to communicate with IGPM to send and receive the following information.
- Send SVM mode conversion requests for SVM output images (e.g. Navi mode→SVM mode)
- Send requests for user SVM view conversion
- Send compensation coordinates for tolerance compensation
- Send warning messages to be indicated in the AVN
- Send any user option changes
