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.
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.
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 is 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.
Smooth longitudinal acceleration
This parameter allows a smoothing level to be applied to the longitudinal acceleration channel that is used for computing the maximum deceleration during a test. When selected, a dropdown menu is presented allowing you to choose a smoothing level (1 by default)

As the trigger may not be activated at exactly the same speed on each run, VBOX Test Suite has a feature that will correct the brake distances to the same speeds.
The corrected trigger distance calculation compensates for the over or under-speed application and normalises the result to a set start speed value maintaining the original initial braking reaction time, as if the brakes had been applied at that exact set speed.
Start Speed (km/h)
Specify the required start speed in km/h.
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.
Auto
You can set this to be done automatically to the nearest 10 km/h by ticking the Auto box.
The corrected distance is calculated by using the following equation:
Corrected distance = Trigger Distance * ((Nominated Speed ^ 2 - End speed ^ 2)/(Trigger speed ^ 2 - End speed ^ 2))
Nominated Speed is the speed nearest to 10 km/h (or mph) of the trigger speed.

This is where you to set up the start and end of the Mean Fully Developed Deceleration (MFDD) analysis period.
Percentage
This deceleration figure is used to show the maximum deceleration a vehicle can achieve. It is usually the deceleration between 80% and 10% of the trigger activation speed, the time at which the vehicle is loaded up and braking at its highest achievable level.
The MFDD is calculated by the following formula (using the default 80% – 10% value):
MFDD = ((v_08)² – (v_01)²) / (25.92 * (s_01 – s_08))
Where:
v_08 is the speed at 80% of the brake trigger activation speed.
v_01 is the speed at 10% of the brake trigger activation speed.
s_01 is the distance at which the speed is v_01.
s_08 is the distance at which the speed is v_08.
Speed
MFDD can also be calculated by using speed. To do this, you must select the Speed option and enter the required From and To values (in km/h). The maximum From speed is the same as the entered Start Speed in the Test Condition section.
If the MFDD To value is below the End Speed entered in the Test Condition section, for example a 35 to 5 km/h test with 80 to 10% MFDD values, you will see a notification warning you that the MFDD conditions are invalid. The test will still run, but VBOX Test Suite will not populate MFDD results.

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).
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.
The Test Results area has the following default columns:
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. |

Avg Decel = (v²-u²)/(2s)
Where:
v is the final velocity, measured in m/s.
u is the initial velocity, measured in m/s.
s is the distance, measured in m.
The software will automatically add columns based on the configuration in the Settings.
