Test Settings

If you are creating a new test, the Settings window will open when you add the new test. This is where you can define the test parameters.

If you have already added a test and you have it open, you can click on the Configure button to open the Settings window to define or amend the test parameters.

VBTS_R139_Settings.svg

Test Condition
Start Condition

This is where you define when the test will start. Use the dropdown menu to decide if the test is to begin on a trigger, or when a set CAN channel reaches a the user-defined positive or negative value.

Note: If a trigger is used as the start condition, the test will not restart if the trigger is activated within 1 second of the previous trigger activation.
 

Minimum Trigger Speed

You can enter a minimum speed at which trigger activation becomes valid. If the trigger is detected below this speed, the test will not start.

Use the up and down arrows next to the value boxes to increase/decrease the speed values. You can also type the required speed value directly into the box.


End Speed

This where you define the speed that will end the test. 

Use the up and down arrows next to the value boxes to increase/decrease the speed values. You can also type the required speed value directly into the box.

 VBTS_R139_Settings_TestCondition.svg
Brake Parameters

These parameters allow the selection of the Brake Pressure and Pedal Stroke channels to be used for the test.
 

Brake Pressure Channel 1

Click on the dropdown arrow to see a list of available channels and select the first input channel for the brake pressure.

 VBTS_R139_Settings_BrakeParameters.svg
Time/Distance Between Runs

To ensure that sufficient time or distance has passed since the previous run was completed or started, you can enter a minimum time and/or distance that must elapse before the next run takes place. If a run takes place before the specified time/distance has elapsed, that run will be highlighted in red to indicate an invalid run.
 

Minimum/Maximum

Select if the settings will apply as the minimum or maximum value.
 

Time (s)

You can set a maximum time between runs. If a run takes place outside of the specified time, that run will be highlighted in red to indicate an invalid run.
 

Distance (m)

You can set a maximum distance between runs. If a run takes place outside of the specified distance, that run will be highlighted in red to indicate an invalid run.
 

Measured from

You can select between two options for the source: it can either measured from the Last completed run (default) or the Last started or completed run (covering situations where a test has been started but then aborted).

Click on the option you want to use for your test.

Reference Test Validation
Ignore deceleration values after 1.5s have elapsed

Sometimes after this period, the deceleration channel can become noisy, which in turn can make the brake test deceleration curve extend out of the test corridor, leading to an invalid test.

Tick this option to make the software ignore deceleration values 1.5 seconds after the brake pedal has been pressed.
 

Apply Butterworth filter to Force & Decel

Tick this option to apply a Butterworth filter of 2 Hz to both the pedal force and deceleration values.

 VBTS_R139_Settings_ReferenceTestValidation.svg
Start of Test Temperature

As many brake test procedures require the brakes to be between, or below, a certain temperature, you can specify the Temperature channels and add a gauge to the dashboard that states if the temperature is OK, LOW or HIGH.
 

Channel

Click on the dropdown arrow to see the available channels and select the channel you want to use for the temperature input. 
 

Min Value

Specify the minimum brake temperature for the test.

Use the up and down arrows next to the value boxes to increase/decrease the speed values or type the required speed value directly into the box.
 

Max Value 

Specify the maximum brake temperature for the test.

Use the up and down arrows next to the value boxes to increase/decrease the speed values or type the required speed value directly into the box.
 

Add

Click on the + button to add another condition.
 

Delete

Click on the X button to remove a condition.

 VBTS_R139_Settings_StartofTestTemp.svg
Test Results Area

The Test Results area is the area that displays all of the results from the current test. In this area, you can include/exclude results from the Chart area, display the average/max/min values and also easily identify any runs that have not met the pass criteria.

Every time you start a new test (via the START button on the dashboard), or load a new file, a new tab will be added to the Test Results area. This gives you the ability to switch between separate tests or files and compare runs from each. You can remove a session from the Test Results area by clicking on the X icon on the session tab.

Note: Whenever you make any changes to the test configuration, maths channels, vehicle dimensions, test units or session data, Test Suite will perform a file scan to apply the changes to the loaded files and update the Test Results, Map and Chart areas.  If you, for any reason, want to cancel this results scan, you can click the red X in the top right corner of the workspace. This will keep the updated settings but will not update the Test Results, Map and Chart areas accordingly.  
Rename File

You can rename a session tab by double-clicking the tab header. Changing the name on the session tab in the software will automatically change the name of the locally saved VBOX file (.vbo or .vbb).

Edit Session Data

By pressing the Edit Data button next to the name of the session in the Test Results area or on the Test Setup tab on the ribbon, you can add vehicle and test information to the session.

  • When in Offline mode, this information will be saved into the VBOX file, meaning that this information will be recalled every time the file is loaded into VBOX Test Suite.
  • When in Online mode, a newly created session will be populated with session data from the previous session.

This information will be included in the test report to make it easier to see under what conditions the test was conducted.

To save time, you can 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, you can 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

 

The Test Results area has the following default columns:

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 in Offline mode, all valid runs will automatically be ticked.
Time (s) The total time the run has taken.
Distance (m) The total distance travelled in that run.
Start Speed (km/h) The speed at which the test started.
aMAX (g) The maximum deceleration during the brake stop.
90% aMAX (g) The 90% value of the maximum deceleration during the brake stop.
Ref-aABS (g) The average deceleration of all the values above the 90% aMAX value.
Pass/Fail Whether the run has passed or failed the test, showing that the deceleration did not exceed the +/-0.5 s corridor as shown in deceleration graph for the brake stop.

The software will automatically add columns based on the configuration in the Settings.
