Kia Cadenza: Surround View Monitoring (SVM) System / Description and Operation
Kia Cadenza YG 2016-2024 Service Manual / Body Electrical System / Surround View Monitoring (SVM) System / Description and Operation
| Description |
Surround View Monitoring System (SVM) is the system that
allows video monitoring of 360 degrees around the vehicle. The system
includes 4 ultra optical camera mounted around the vehicle (front, both
sides, rear).
The video from these cameras are applied with distortion
compensation, time point conversion, and video merging technologies to
provide sky-view image of the vehicle''s surrounding area, as well as
various other view modes.
The SVM System provides video feed of the vehicle''s
surrounding area while parking or during low speed driving to the driver
to enhance safety and driver''s convenience.
In addition, the system also displays video image of
vehicle''s surrounding area, and includes steering wheel synchronized
guide line indication, front and rear object warning, and A/S (including
In-Line) tolerance compensation features.
It''s a system that displays the video, from ultra optical
cameras mounted on 4 sides of the vehicle, on the Head Unit Screen. It
shows 360 degrees sky-view image of the vehicle''s surrounding area, as
well as various other view modes. The SVM System provides video feed of
the vehicle''s surrounding area while the vehicle is parked or during
low speed driving to the driver to enhance safety and driver''s
convenience.
| Major Features |
| 1. |
Display Vehicles Surrounding in Video
The surrounding area video display function displays the 360
degrees video image captured through 4 cameras to the driver through the
Head Unit Screen while the vehicle is moving at low speed or going
reverse. The SVM System displays total of 8 video modes for displaying
surrounding video based on the vehicle driving state and the driver''s
selection. |
| 2. |
Guide Line Indication & Steering Wheel Synchronized Feature
The Guide Line Indication & Steering Wheel Synchronized
Feature is the function that assists the driver in parking by
synchronizing the steering wheel with the rear view video display marked
with a guide line to help anticipate the direction of the vehicle going
reverse. |
| 3. |
Front/Rear Object Warning (Obstacle Detection Feature)
The system receives obstacle warning signal from the PAS or
SPAS sensors mounted on the front/rear of the vehicle and displays the
obstacle location on the AVM Head Unit Screen. |
| 4. |
Tolerance Compensation (including A/S)
Manual Tolerance Compensation Software is embedded in the SVM
ECM to compensate the SVM deviation that may occur due to assembly line
installation tolerance. You must first setup proper work environment in
order to perform correct tolerance compensation. |

SVM Mode Entry Conditions
The vehicle information is accessed regularly, even after
entering SVM mode. When the conditions are met, conversion from front
mode to rear mode is available, and vice versa.
When the mode is converted, the view displayed on the screen
can be the initial view or the previous view depending on the
conditions.
If the mode for conversion is the initial entry, the default
view is selected based on the front or rear. If a continuous front-rear
conversion mode occurs as forward and backward movement are repeated for
parking, the previous view is recalled and displayed.
| – |
Initial Entry: When the rear and front mode view in SVM mode is displayed on the screen for the first time |
| – |
Re-entry: When switching from SVM mode to another mode, without turning off SVM, and returning to the previous mode
(e.g. Rear → Front → Rear: Re-enter rear mode / Front → Rear → Front: Re-enter front mode) |
| Switch mode | Vehicle speed | Gear | SVM Switch | Display view |
| Rear → Front | below 20 kph | R Range or P Range excluded | ON | Initial Entry: Front view set in the initial view mode option |
| Re-entry: The last view mode displayed in the previous front mode | ||||
| Front → Rear | Irrelevant | Reverse Gear | Irrelevant | Initial Entry: Rear view set in the initial view mode option |
| Re-entry: The last view mode displayed in the previous rear mode |
SVM Mode Disengagement
If the conditions below are satisfied while in SVM mode, the SVM is turned OFF and no video is displayed.
| OFF Mode | Vehicle speed | Gear | SVM Switch | Notes |
| Front mode | over 20 kph | R Range or P Range | OFF | If any of the three conditions are satisfied |
| Rear mode | Irrelevant | Except R gear | Irrelevant | If any of the two conditions are satisfied |
SVM Options
Considering the user''s convenience, the SVM provides three options for the user to select.
The window for changing options (parking guide settings) is
displayed by the AVN. Only the changed options are forwarded to the SVM
unit through M_CAN.
These three options are applied as soon as they have been
selected by the user. Based on the conditions, the initial views
displayed are as follows.
| Option | Function | Default setting |
| Guideline steering interlocking | Interlocks with steering to display the driving direction of the vehicle during parking. | Classification code |
| Close range warning indicator | Indicates front and rear obstacle detection | Classification code |
| Initial view mode setting | Default view displayed when entering SVM mode | Front + around view |
| Rear + around view |
Operations for Guideline Steering Interlocking Indications
The indication for the guideline steering interlocking trace
uses the steering wheel angle value periodically received by the SVM
unit through C-CAN.
A rear area that displays a 130 degree image of the rear mode
(two-split mode) and a wide view are displayed with the expected car
movement trace.

Indications for neutral trace lines
If the steering angle is neutral, the neutral trace line is
indicated in blue, which shows the expected movement trace of the car.
This line is displayed with the guideline steering
interlocking trace line and is also a fixed line that is not interlocked
with the steering angle operation. |
