Robot Modes - Vehico

VB3iSL-RTK is compatible with Vehico robot systems, allowing the user to complete high accuracy ADAS tests.

Hardware configuration

For successful integration with the Vehico system, the user will need the following equipment in each Vehicle: -

  • 1 x VB3iSL-RTK system (with both GPS antennas connected and placed 1 m apart*)
  • 1 x IMU04 (connected to the VBOX via the RLCAB119)
  • 1 x IMU Roof Mount
  • 1 x DGPS Radio and antenna
  • 1 x ADAS vehicle to vehicle communication radio and antenna

VBOX Manager Configuration

Enabling Vehico Mode

  1. Connect VBOX Manager to the VBOX.
     
  2. Enter the 'SETUP' menu of VBOX Manager.
     
     
  3. Select the 'Robot Modes' option and choose 'Configure'.

Selecting the ‘Vehico - Auto Configure' option within VBOX Manager will automatically configure the VBOX to work with the Vehico system by applying the following settings:
 

  • Dynamic Mode – 'High'
  • Hi Dynamic KF – 'Disabled'
  • Log Rate – '100 Hz'
  • DGPS Mode – 'RTCM v3*'
  • Dual Antenna Mode – 'Enabled'
  • Dual Antenna Orientation – 'Pitch Mode'
  • Dual Antenna Separation – '1.000 m**'
  • IMU Integration – 'Enabled'
  • IMU Roof Mount – 'Enabled'
  • VCI CAN Rate – '500 kbit/s'
  • VCI CAN bus – 'RS232 port'
  • VCI Termination – 'Enabled
  • The following CAN IDs will also be switched on, more information on these is available here:-
    • 308
    • 309
    • 314
  • Longitudinal and lateral acceleration values will be output in m/s² rather than g
  • The following CAN pass through channels will be applied:-
    • 600 - X Acceleration

*Please note that the user must manually select the correct DGPS serial rate that relates to the radio system they are using.

**1.000 m is the default dual antenna separation. If it is not possible to gain a 1 m separation, then the user will have to enter the required separation value in the 'Dual Antenna' area of VBOX Manager.

Setting the Datum Point

The Datum point is the origin point of the local X-Y coordinate system, from which all positional information will reference. Selecting will use the current location of the GPS antenna as the Datum point.

Setting the Track Direction

The track direction dictates the direction which the Vehico system will consider it’s ‘North’ value. VBOX 3i will automatically work out the heading and apply this heading as the track direction.
 

  1. After setting the 'Datum Point' drive along the track to another location.
     
  2. Scroll to 'Track Dir.' and select.

Setting the Heading

Alternatively to setting the 'Track Direction', a numerical heading value can be manually entered.
 

  1. Scroll to 'Enter Heading' and select.

  2. Enter the heading value by pressing the scroll wheel to move along the digits and rotating to the desired number, selecting past the final digit will store the value.

Saving, Loading and Clearing the Datum Point, Track Direction and Heading

Once the user has defined the Datum point and track direction, it is possible to save this information to be recalled at a later date. To do this the user must save the information by pressing the ‘Save’ option within VBOX Manager, doing this will allow the user to either create a new file or overwrite an existing file.

Once saved, it is possible to load this information into the VBOX using the ‘Load’ option on VBOX Manager, allowing the user to select the required file.

To clear the current track direction and datum point, the user can use the ‘Clear’ function. Selecting this option will clear the current track direction before setting the current antenna location as the datum point.

Setting the ADAS mode

The user will still need to manually set the VBOXs as either a ‘Subject Vehicle’ or ‘Target Vehicle’ in the '1 Target' ADAS mode. More information on this is available here.

Channel Changes

Once Vehico mode is enabled, the Position channels output over CAN (IDs 308 and 309) are now in a local X and Y coordinates, rather than the standard global coordinate system the VBOX typically uses. The origin of this local X and Y system will be the user nominated Datum point.

The Latdif_tg1 and Lngdif_tg1 channels also change function, being populated with the Target’s position with regards to the Datum, i.e the x and y position in metres.

As the Vehico system allows the user to define a Track direction, the VBOX’s True heading 2 value is calculated with reference to the ‘y’ direction (Track Direction) in the image below, as opposed to using North as the reference.

Disabling Vehico Mode

Please note that the VBOX will continue to operate in ‘Vehico mode’ until either a different Robot mode is selected (DSD, ABD) or ‘Off’ is selected from within VBOX Manager.
