Surround View Monitor (SVM)

  

1) SVM unit basically transmits data via C-CAN only.

Steering wheel angle sensor : C-CAN

Vehicle speed sensor : C-CAN

2) It functions as a CGW (Central gateway) of C-CAN ↔ B-CAN, P-CAN, MM-CAN in ICU.

e.g. The signal of unit using B-CAN, P-CAN, MM-CAN is transmitted after converting to C-CAN in cluster.

SVM monitor : MM-CAN

Transmission : P-CAN (TCU)

PDW sensor : B-CAN (IBU)

Component Functions

Steering Wheel Sensor : The steering wheel angle is transmitted to the SVM unit through the C-CAN communication line for display of the rear view and steering assisted parking guideline.

Transmission : The shift lever position is transmitted to the SVM to determine its operation.

Front/Rear PDW : An alarm screen to display obstacles appears on the omnidirectional monitor that receives data from the parking distance warning (PDW) sensor on the front and rear.

SVM Unit : It controls the overall operations for video signal processing/input/output, vehicle communication (CAN), and SVM system.

SVM Switch : The SVM switch signals are input to determine whether or not to provide images in forward display mode.

Vehicle Speed Sensor : The vehicle speed is transmitted to the SVM to check the SVM operation condition.

Camera (4 unit) : Each unit is mounted on the front, rear, and left/right outside mirrors to capture images from the surroundings and to transmit them to the SVM unit.

AVN Monitor : It provides the driver with the output image from the SVM unit through the monitor of the AVN (Audio, Video and Navigation system) head unit.

Description and operation
Description

Surround View Monitor (SVM) allows video monitoring of 360 degrees around the vehicle. The system consists of 4 ultra optical cameras mounted around the vehicle (front, both sides and rear).

The video images 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.

Also, it features steering wheel synchronized guide line indication, front and rear object warning, and A/S (including In-Line) tolerance compensation.

This system displays the video images 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 arounding area, as well as various other view modes.

Blind-spot View Monitor (BVM)

Blind-spot View Monitor (BVM) is a driving safety system that helps provide a more comprehensive views on areas which is not usually visible by the side mirrors when the vehicle tries to change the lane.

The BVM system provides a driver a more comprehensive view which is not usually visible by the side mirrors in certain situations like swithing drive lanes. The system helps to avoid any blind spot mishaps.

The rear side view is displayed in the cluster screen when the turning lights are in operation as the light switch goes up and down by the driver.

The SVM also provides an edited view of the left side/ right side without adding more cameras.

It helps minimize the distraction of the driver by displaying the rear side view that is usually hard to see.

  

The video will be played even though the side mirrors are folded. But it does not provide a proper view of the surroundings.

The video quality may be lower than the SVM video as the size of the original image has to be adjusted to fit the cluster.

The screen may temporarily fades out with changes in light conditions during daytime or with a sunrise or a sunset. Or when the car enters the tunnel.

The view of the surrounding objects provided by the system may look far away than views that are obtained by the side mirrors.

The brightness of the rear side video may change due to a mode switching delay of the SVM/BVM.

Major Features

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 view modes in SVM mode are 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)

SVM System

1.

SVM Video Output

The SVM ECU displays the images from four installed cameras after passing the distortion correction and image synthesis steps and then displays the steering assist guidelines in analog format.

2.

SVM Switch

The signals are input for control in forward display mode when the switch is ON.

3.

Ignition Input

The SVM ECU displays video only on IGN2 ON and limits video output to SVM OFF when IGN2 is OFF.

In order to check whether the IGN2 is ON, the SVM ECU uses the signals to the IGN pin or it uses the M-CAN messages routed to the C-CAN from the IGPM (Gateway).

4.

Switch Indicator Output

The SVM ECU outputs the power of the LED on the SVM switch in PWM waveform to notify the driver whether or not the SVM switch is pressed.

5.

Chassis CAN Input (C-CAN)

The SVM ECU receives the vehicle status data through the C-CAN and determines whether or not to perform key operations of the SVM.

6.

Multimedia CAN Input / Output

The related information is processed after receiving M-CAN signals routed from the ICU to the C-CAN.

The routed M-CAN signals are exchanged for data transmission and reception as follows:

Inspection

Tolerance Compensation

Tolerance compensation compensates for the error margins of surround view video that occur due to the installation tolerance when the four cameras that comprise the SVM system are installed.

Tolerance compensation must be carried out when the following actions are performed:

When removing and installing a wide camera.

When conducting a body task such as the trunk task that causes the focus of the wide camera to change.

When replacing the door mirror with a wide camera.

When replacing the surround view monitoring unit.

Tolerance Compensation Environments

The Procedure of Manual Tolerance Compensation

1.

Prepare in advance as below.

Confirm that the car hood, trunk and doors are closed.

Close the door after getting in on the driver side.

Switch the ignition to "IGN".

Unfold all side mirrors.

Shift the gear to N.

Check the flashing state of LED indicator lamp in the SVM switch.

During the advance preparation, do not install exhaust inhaler or other equipment that may block the view of rearview cameras.

Also, as exhaust fume may block the rearview image, blow off the smoke by using a fan before performing tolerance compensation with IGN ON.

Engage foot brake or electronic parking brake (EPB) to hold vehicle in place.

2.

Before entering tolerance compensation mode, to check normal operation of SVM ECU and cameras, perform the following.

Check that initial setting screen of SVM is displayed. (Front view image + surround view image when shifted to N)

Check that front, rear, left and right images of surround view monitor are properly displayed.

If images are properly displayed, enter tolerance compensation mode. Otherwise, if images are abnormally displayed or are not displayed, replace relevant part.

3.

Install two compensation scales, two compensation reference line boards, and four compensation target boards around the vehicle by referring to the manual provided with the tools.

  

Align centers of front wheels to "B-type" on the compensation reference line board.

Accurately set the location (distance/angle) of the center of white and black compensation board as this is the reference point.

Front/rear and left/right alignment error margin should be below 3 cm.

Rotation error margin when aligning vehicle should be within 1° to left/right.

4.

Maintain ignition "ON" with vehicle stopped, check that the gear is in P, and engage parking brake even on flat ground.

5.

Perform work with SVM switched "ON".

6.

Connect the KDS to vehicle.

7.

Select vehicle model and system.

8.

Enter additional function in KDS.

9.

Perform SVM manual tolerance compensation as shown on KDS diagnostic device.

  

When "SVM tolerance compensation - Manual" is clicked on the KDS diagnostic device screen, the SVM switch indicator lamp will flash.

  

Before matching calibration points: "+" green light flashes

When clicking [OK] after matching calibration points: "+" red light ON

Match four frontal calibration points, and then perform calibration in the order from rear → left → right.

10.

To confirm completion of calibration, check the vehicle and calibration line on AVN monitor and click [OK].

If calibration has not been properly performed, click [Cancel] and reenter calibration points.
