Description and Operation

Description

The Surround View Monitor (SVM) is a system that provides 360-degree video surveillance around the vehicle. The system includes 4 ultra-optical cameras installed around the vehicle (front, both sides, rear). Video from these cameras is processed with distortion compensation, point conversion time and video fusion technology to produce a bird's-eye view image of the vehicle's surroundings, as well as various other viewing modes. The SVM system provides video of the vehicle's surroundings during parking or while driving at low speed to improve driver safety and convenience. In addition, the system displays the video image of the area around the vehicle and includes synchronized guide line indication on the steering wheel, front and rear object warning, and A/S tolerance compensation function (including linear).

This is a system that displays video from ultra-optical cameras installed on the four sides of the vehicle on the head unit screen. It shows a 360-degree bird's-eye view image of the vehicle's surroundings, as well as various other viewing modes. The SVM system provides video of the vehicle's surroundings while the vehicle is parked or driving at low speed to improve driver safety and convenience. Blind-Spot Monitor (BVM) The Blind-Spot Monitor (BVM) is a driving safety system that helps provide a more complete view of areas that are normally not visible in the side mirrors when the vehicle attempts to change lanes.

The BVM system provides the driver with a more complete view that is normally not visible in the side mirrors in certain situations, such as when changing lanes. The system helps to avoid any failures in blind spots.

• The rear view is displayed on the cluster screen when the turn signal is operated, and the headlights operate when the driver raises and lowers the light switch.
• SVM also provides an adjustable left/right side view without adding additional cameras.
• This helps minimize driver distraction by displaying the rear side view, which is normally difficult to see.

Video will play even when the side mirrors are folded. However, it does not provide an adequate view of the surroundings. Video quality may be lower than SVM video, because the original image size must be adjusted to fit the cluster. The screen may temporarily go black when lighting conditions change, such as during daytime or at sunrise or sunset, or when the vehicle enters a tunnel. The view of surrounding objects provided by the system may extend further than the views obtained in the side mirrors. The brightness of the rear side video may change due to the SVM/BVM switching delay mode.

Main Specifications

1. 1
   Display of Vehicles Surrounding the Vehicle. The surround view display function shows a 360-degree video image captured by 4 cameras to the driver through the head unit screen when the vehicle moves at low speed or in reverse. The SVM system displays a total of 8 video modes for displaying the surrounding area based on the vehicle driving state and the driver's selection.
2. 2
   Guide Line Display and Steering Wheel Synchronization Function. The guide line display and steering wheel synchronization function assists the driver during parking by synchronizing the steering wheel with the rear view video display, marked with a guide line, to help anticipate the vehicle's direction of travel when reversing.
3. 3
   Front/Rear Object Warning (Obstacle Detection Function). The system receives an obstacle warning signal from the PAS or SPAS sensors installed at the front/rear of the vehicle and displays the obstacle location on the SVM head unit screen.
4. 4
   Tolerance Compensation (Including A/S). Manual tolerance compensation software is built into the SVMECM to compensate for SVM deviation that may occur due to assembly line tolerance. You must first set up the proper operating environment to perform correct tolerance compensation.

SVM Mode Entry Conditions: Vehicle information is accessed regularly, even after entering SVM mode. When the conditions are met, switching from front mode to rear mode and vice versa is possible. When switching modes, the view displayed on the screen may be the initial view or the previous view depending on the conditions. If the switching mode is the initial entry, the default view based on front or rear is selected. If continuous front-rear switching occurs, as forward and reverse movement is repeated for parking, the previous view is recalled and displayed.

• Initial Entry: when the front or rear view in SVM mode is first displayed on the screen
• Re-entry: When switching from SVM mode to another mode, without turning off SVM, return to the previous mode (e.g., Rear → Front → Rear: re-enter Rear mode / Front → Rear → Front: re-enter Front mode)

Switching Mode	Vehicle Speed	Mechanism	SVM Switch	Display View
Rear → Front	below 20 km/h	R range or P range excluded	ON	Initial Entry: front view is set in the initial view mode option.
				Re-entry: the last view mode displayed in the previous front mode.
Front → Rear	Not applicable	Reverse Gear	Not applicable	Initial Entry: rear view is set in the initial view mode option
				Re-entry: the last view mode displayed in the previous rear mode.

SVM Mode Cancellation: If the conditions listed below are met while in SVM mode, SVM is turned off and the video is not displayed.

OFF mode	Vehicle Speed	Mechanism	SVM Switch	Notes
Front mode	more than 20 km/h	R range or P range	OFF	If any one of the three conditions is met
Rear mode	Not applicable	Except R gear	Not applicable	If any one of the two conditions is met

SVM Options: For user convenience, SVM provides three options for the user to select. The option change window (parking assist system settings) is displayed on the AVN. Only changed options are sent to the SVM unit via M_CAN. These three options are applied as soon as they are selected by the user. Depending on the conditions, the initial displayed views are as follows.

Option	Function	Default settings
Steering Lock	Steering lock guide lines to show the vehicle's direction of travel during parking.	Classification code
Close Distance Warning Indicator	Indicates obstacle detection at the front and rear	Classification code
Initial View Mode Setting	Default view displayed when entering SVM mode	Front view + surround view
		Rear + surround view

Operation for Steering Lock Guide Line Display. The steering lock guide line display uses the steering wheel angle value periodically received by the SVM unit over the C-CAN bus. The rear area, which displays the 130-degree rear view image (two-section mode) and the wide view, is displayed with the expected vehicle travel path.

   SVM Image Display: Images received from the four cameras installed on the vehicle pass through the image distortion correction logic and the image merging process. The H/UNIT displays these images together with other additional functions, such as parking guidelines linked to the steering wheel, on the AVN screen.

7. 7
   Ignition Input: The SVM unit displays the image only when IGN2 is on, and restricts image display with the SVM off when IGN2 is off. The SVM unit uses the signal received at the IGN terminal or the M-CAN message routed from the IGPM (gateway) to the C-CAN to determine IGN2 on/off status.
