Lanes

The lanes used within the test can be either loaded from a saved file or surveyed live within the software when in 'Online' mode. Once lanes have been configured, you can use the window at the bottom to visualise (check) the lanes, designated as L1 and L2. You are also able to change the associated colours and apply smoothing.
 

VBTS R79 Settings Lane.png
 

Note: If only 1 lane is available, the software will still calculate lane range values.

Load Lanes

To load the lanes from saved .vbo (VBOX), .vbc (lane departure) or previously surveyed files, select the dropdown menu next to a lane and click on 'Load Lane File'. Navigate to the saved file and select 'Open' to load in to the software. Repeat for the other lane.

Interim result(s)

The software allows the user to display intermediary results called ‘Interim results’. The Interim results are determined by adding in ‘Interim Conditions’.

Pressing the '+' button will add a new interim result. It is possible to have this line appear at ‘Every’ instance of the value (e.g. Every 10 km/h), ‘At’ an instance of a value (e.g. Only at 10 km/h) or 'Between' values (e.g. Between 30 km/h and 50 km/h).

When 'Columns' is selected, each interim result is shown as a column within the right hand side of the results table, if 'Separate Table' is selected, each interim result is shown as a row in a separate table next to the results table.

Completing a Test

To start an online test, the user must first select the correct COM port from the ‘Online’ drop down menu in home tab. Once connected to a VBOX, the dashboard will change to show the 'START', 'STOP' and 'RESET' buttons.

Setting Start/Finish Lines

Before the software can begin to produce results, the user must first set the ‘Start Gate’ and ‘Finish Gate’ lines. To do this when connected to a VBOX, the user must drive to the required point on the track and press the relevant button on the ‘Test Setup’ tab. Once pressed, the software will require the user to drive away in a straight line to understand the direction of which the line should be set.

To set the start lines in a previously recorded file, the user must position the map cursor on the correct part of the track and then press the relevant button on the ‘Test Setup’ tab.

No matter whether the user is connected to a VBOX or not, Racelogic recommend that the saving of test settings once the lines have been set. This will allow the user to repeatedly recall these test lines without having to set them individually for each test.

Starting, Stopping and Resetting a Test

By pressing the 'START' button, the software will add a tab to the Test Results area ready to be populated with results once the start and end criteria have been met. The 'START' button will also change to a 'PAUSE' button, allowing the user to pause the test. To resume the test, simply press the 'RESUME' button.

To finish a test, simply press the 'STOP' button. This will stop all open tests. Once the stop button has be pressed, future results cannot be added to that results tab. Pressing the 'START' button will open up a new results tab, however once the stop button has been pressed, the user will be required to calibrate the wheel speeds again (if wheel speed channel(s) are selected) before a new test can be started.

If, for any reason, a mistake has been made during the test, it is possible to restart the test by pressing the 'RESET' button and again this will require a calibration of the wheel speeds.

​Test Results Area

The test results area is the area that displays all of the results from the current test. Within this area it is possible to include/exclude results from the chart area, display the average/max/min values and also easily identify any runs which have not met the pass criteria.

Every time a new test is started (via the 'START' button on the dashboard), or a new file is loaded, a new tab will be added to the test results area, allowing the user to switch between separate tests or files and compare runs from each. A session can be removed from the results area by pressing the ‘x’ icon on the tab.

Rename file

It is possible to rename the session tab by double clicking on the tab header. Changing the session tab within the software will automatically change the name of the locally saved .vbo file.

​Session Data

By pressing the 'Edit Data' button  steering_wheel1 (11).jpg next to the name of the file/run or in the ‘Test Setup' ribbon bar, a new window will be displayed whereby the user can add various different pieces of vehicle and test information, such as:-

Vehicle Overlay

The vehicle overlay section allows the user to configure the required vehicle measurement points and enter antenna placement offsets.

There is no limit to the number of vehicle measurement points that can be set.

Points should be measured from the primary antenna as shown below.

When in 'Online' mode, a newly-created session will be populated with session data from the previous session.

Note: The 'Other Information' parameters are purely optional and has no effect on the test or test result.
 

To save time, it is possible for the user to import and export the session information for use in other sessions (the entire range of data is exported not just the visible screen).
 

Once the session information has been completed, it is possible to export the data to a .vbses file. This file will contain all the session information that can then be imported into the open session information field.

Result Columns

 

VBTS R79 MLA Results.png
 

Along the top of the Test results area are some default columns. These columns are:-

  • Run – Indicates which run number the results relate to, with run one being the first run completed. There is also a selection box that, when ticked, includes that run in the graph and into the Average/Max/Min/Standard Deviation calculations. Once selected, a coloured square will appear to indicate which colour this run is displayed as on the graph.
    Note: If you are loading a file offline, all valid runs are ticked automatically.
  • Time – The total time the run has taken.
  • Min Speed – The minimum speed during the run. If the Vsmin parameter is exceeded, this column will be highlighted deep red and the whole run will be highlighted light red.
  • Max Speed – The max speed during the run. If the Vsmax parameter is exceeded, this column will be highlighted deep red and the whole run will be highlighted light red.
  • Lat Accel (Max) – The maximum absolute value of lateral acceleration between the start of test and end of test. If the aysmax parameter is exceeded, this column will be highlighted deep red and the whole run will be highlighted light red.
    Note: This channel is subject to a 4th order Butterworth filter with a 0.5 Hz cutoff.
  • Lat Jerk (Max) – The maximum absolute value of Lateral Jerk, which is the rate of change of lateral acceleration, smoothed over 0.5 s. This parameter has a pass condition of ±5 m/s³, if the value is exceeded, the column will be highlighted deep red and the whole run will be highlighted light red.
  • Lane Cross – A YES/NO indication of whether the vehicle crossed the lane, if the Lane is crossed, this column will be highlighted deep red and the whole run will be highlighted light red. 
Adding a Column

It is possible to add columns to the test results area by selecting the ‘Add’ button on the ‘Test Setup' tab in the ribbon bar. Selecting this button will display a drop down list of all available channels which the user can select to display as a results column. By default, this value is displayed as an ‘At End’ value, whereby the column will display the value of that parameter at the end of the run.

It is also possible to right click anywhere in the test results area and select the ‘Add’ option from the dropdown menu.

To remove a column, simply select the ‘x’ icon that appears when you hover over the column title. If a column has been removed, it can be added again by selecting the ‘Add’ button and choosing the desired channel.

UNR79 Specific L1 and L2 Measurements

Within the Add column drop down menu, a list of UNR79 specific measurements are available to choose from, e.g. RangeP1_L1.


These lane range measurements are calculated perpendicular to lane headings. The created channels will be labelled L1 and L2 relative to what is shown in the 'Lane Settings' window. The range values are signed negative when the lane is to the left of the vehicle and positive when the lane is to the right of the vehicle.


Two points in relation to the lanes will exist for every vehicle measurement point. For example, the P1_L1 measurement is the range of the first defined vehicle measurement point to lane 1.

Editing a Column

As default, a column is added as an ‘At End’ condition. It is possible to change this by selecting the column title you wish to edit (once selected, the column will be highlighted in yellow) and changing the condition in the ‘data column’ area in the ‘Test Setup’ tab of the ribbon bar.
 

VBTS Edit Column.png
 

It is possible to choose the following conditions for the main results:-

  • Avg – The mean average of the parameter during the run.
  • Max – The maximum value of the parameter during the run.
  • Min – The minimum value of the parameter during the run.
  • Delta – The difference between the start and end value of the parameter.
  • Std Dev – The standard deviation of the parameter during the run.
  • At Start – The value of the parameter at the start of the run.
  • At End – The value of the parameter at the end of the run.
  • Gate – The value of the parameter at the crossing of the specified gate line (e.g. Start of Test).


It is also possible to change the displayed parameter, by using the other drop down menu on the ribbon tab and selecting the desired parameter.
