Land Rover Discovery: Proximity Camera System - Operation

The proximity camera system provides the driver with a visual-aid when maneuvering the vehicle at low speeds. The system uses the Camera Control Module (CCM) to capture the camera data and display the resulting images on the Touch Screen (TS), providing the driver with a 360º view around the vehicle. The camera system is also supported by various drivingaid features where graphical information and warnings are superimposed onto the images displayed on the TS.

Automatic Operation

Once the vehicle speed exceeds 18 km/h (11 mph) the images will automatically switch off.

Once automatically switched off, the camera view will be disabled until:

• Another ignition cycle occurs and the system is automatically functioned.
• The camera system is manually selected on the TS.

The vehicle speed reduces under 18 km/h (11 mph).

With the ignition 'On' and 'Reverse' selected, the camera system will display the view from the rear of the vehicle.

Manual Operation

• The camera home page is accessed using the 'Cameras' icon on the TS or Audio Head Unit (AHU) (depending on vehicle specification) in the 'Extra Features' menu.
• Camera views can be accessed at all times.

Selecting Views

Displayed on the home page are real-time images transmitted from each of the five cameras. Any two of the images can be selected and enlarged to view side-by-side on the screen. When viewing any two images, any single image can then be selected to view as a full screen image which can be zoomed and panned around using the magnifier and arrow icons.

Manual Proximity View

Selecting proximity view from the camera home screen will display a combination of three images from the front passenger side cameras. These images provide the driver with an enhanced view of the area forward and opposite the driver.

Proximity Camera System

The proximity camera view images are overlaid with:

• Dashed lines representing the perimeter of the vehicle.
• Solid lines representing the predicted trajectory of the vehicle; calculated from the steering wheel angle sensor.
• Colored bars represent the amount of distance between the vehicle and the object being approached. Working in conjunction with the standard 'rear parking aid' this adds a visual representation to the existing audible warning. The distance data is received from the Camera Control Module (CCM) through the Medium Speed (MS) Controller Area Network (CAN) comfort bus via the Gateway Module (GWM).

The reversing-aid graphics can be disabled in the settings menu or by touching the TS (touch screen) whilst reverse gear is selected and the camera view is displayed.

Special Views

The special views are a selection of pre-set views that provide the driver with some useful driving aids. These can be considered as a shortcut to some pre-determined images that have been developed to assist the driver in various situations:

• Kerb view: downward view from the two door mirror cameras.
• Junction view: outward view from the two front cameras.

System Calibration

This level of accuracy must be maintained after any service procedures are performed on the vehicle that affects the proximity camera system. Should the control module or any one of the cameras require replacement, static re-calibration must be carried out using the approved Land Rover diagnostic equipment.

Camera replacement is detected by the Camera Control Module (CCM), through the recognition of a new serial number during the 'camera count' procedure that takes place during the 'ignition on' phase via the Local Interconnect Network (LIN) bus.

If a new camera is installed calibration must be performed using the diagnostic equipment and the vehicle's Touch Screen or Audio Head Unit (AHU) (depending on audio system vehicle using). During the calibration procedure, setup software in the control module overlays fine colored lines on the TS or AHU highlighting reference points on the bodywork. For example, the mirror camera image must capture the side repeater indicator, the shut-line of the doors and the lower sill trim.

Direction arrows are pressed to shift the image in the desired direction to meet the reference points viewed on the TS or AHU.

Adjustments include:

• Up
• Down
• Left
• Right
• Rotation

When the reference points correspond exactly, the setting is saved and the calibration procedure is complete for that camera.

If body repairs are performed that affect the camera system, a calibration procedure must be executed after the repairs are completed.

System Fault

In the event of camera fault, a Diagnostic Trouble Code (DTC) is logged in the Camera Control Module (CCM), and an icon is presented to the driver on the Touch Screen (TS) or Audio Head Unit (AHU) (depending on audio system vehicle using) where the camera image would normally be viewed.
