***Display parameters calculated using UTC time, for example; Peak Deceleration must be performed either side of 11.59pm. Tests, which start before 11.59 and end after 12.00 may contain invalid data.

Brake Parameters

Code Name Units
TV * Speed at trigger km/h or mph
TD * Distance from trigger m or ft
TT * Time from trigger s
DG * Peak deceleration g
AD * Average deceleration (click for description) m/s²
DO * Average deceleration 2 (click for description) g
OD * Corrected distance m or ft
ST ** Deceleration time s
DS Deceleration distance m or ft

* A brake trigger must be present in order to use these parameters. 

**To set up the start and end speed for the acceleration / deceleration tests enter the CONFIG DISPLAY MENU from screens 1, 2 or 3, scroll across until the screen displays ACCEL/DECEL SETUP press OK to enter the test set-up menu.


Accel Parameters  

Code Name Units
VT Maximum speed km/h or mph
AT ** Acceleration time s
DA Acceleration distance m or ft
OV Velocity at target distance km/h or mph
OT Time to target distance s

**To set up the start and end speed for the acceleration / deceleration tests enter the CONFIG DISPLAY MENU from screens 1, 2 or 3, scroll across until the screen displays ACCEL/DECEL SETUP press OK to enter the test set-up menu.

CAN Parameters

The first 32 CAN channels currently being logged by the VBOX are selectable here. These can include internal module channels such as internal A/D parameters, ADAS parameters, IMU KF parameters and dual antenna parameters.

If no channels are currently being logged then you will be unable to enter this submenu.

Note: To allow the MFD to read the available CAN channels it must be connected up to a VBOX and VBOX Setup entered. Failure to do so will result in this list being blank or incomplete.

Kalman Filter Status

The table below shows the hex and decimal numbers associated with Kalman filter status. The VBOX can have a number of these status flags active at the same time so the resultant number shown in VBOX Tools or a logged file will be a result of adding together the numbers of the active statuses shown below.

Kalman Filter Status Hex Decimal
kf_Clear 0x0000 0
kf_NEWIMUVersion 0x0001 1
kf_TestMode 0x0002 2
kf_Use 0x0004 4
kf_Initialised 0x0008 8
kf_IMUDataFound 0x0010 16
kf_GoodLock 0x0020 32
kf_Reset 0x0040 64
kf_CoastingTimeout 0x0080 128
kf_IMUFound 0x0100 256
kf_Initialise 0x0200 512
