    Counteracting the Lever-Arm effect during Brake Tests

    It is largely accepted that the most accurate and cost effective way to perform brake distance tests is with the use of a high speed GPS sensor which can measure distances to within a few cm.

    During a brake test however, the necessary placement of a GPS antenna high up on the vehicle roof can lead to a certain amount of unwanted variation in GPS speed output. This occurs due to the way that a car pitches forward and backwards as it travels, a feature particularly prevalent during braking. Due to the roof momentarily travelling faster than the rest of the vehicle, the ‘lever-arm’ effect can cause an overshoot in the GPS speed recorded compared with the speed at the wheels.

    By using an Inertial Measurement Unit (IMU04) with a VBOX3i, it is now possible to compensate for this overshoot. It works by calculating the pitch and roll angles of the vehicle, and translates the data measured at the antenna point on the car roof to the Centre of Gravity where it is mounted. As a result the speed measurement closely represents the true speed of the vehicle.

    You may have seen the article that was published recently in Vehicle Dynamics International magazine which focusses on using an Inertial Measurement Unit to aid GPS test systems. Click here to read more >

    Online product tutorials

    To help you to get the most out of your VBOX we have started to produce insightful product tutorials. These are designed to enable new customers to learn how VBOX systems can be used to log high accuracy speed and position data, and show existing customers additional VBOX functionalities.

    The first product tutorial is focussed on how integrating an Inertial Measurement Unit (IMU04) with a VBOX3i can improve the accuracy of brake and vehicle dynamic tests. Click here to view the tutorial >

    VBOX show season! EuroBrake, Sensor & Test and ATE Europe

    As ever we will be exhibiting at ATE Europe (24-26 June) but this year we are attending two shows that are new to us: EuroBrake (13-15 May); and Sensor and Test (3-5 June) – where we also have a daily demonstration of the new IMU04’s capabilities.

    If you are attending any of these shows please feel free to visit us, we will be happy to discuss any testing needs you may have.

    MIRA installs RTK transmitter

    MIRA proving ground have recently installed a permanent VBOX compatible GPS base station which transmits RTK correctional signals to nearly every part of the facility.

    This means that any VBOX3i RTK system (with a suitable radio) can be used to perform tests which require 2cm positional accuracy - reducing costs and the time required to validate applications like Lane Departure Warning and Blind Spot Detection.

    One of the by-products of this is consistency in brake testing. Although positional accuracy is not required to measure stopping distances, it does allow very accurate comparisons to be made from slightly different areas of the braking zone, where general road surface wear can lead to variations in results. The ability to know at which point of the track the tests are being performed can be used to average out these differences.



    To help us keep you up to date with the latest vehicle test solutions, we have set-up a dedicated VBOX Blog.

    Convert OEM CAN data files to digital or analogue signals

    New firmware (v1.0.5) for the CAN to Analogue Output Module now allows it to be used alongside the Racelogic Config software and support the huge database of OEM Racelogic CAN database files (REF files).

    By adding this support, users can download and import vehicle CAN data straight into the module and convert it into analogue, digital or digital frequency signals.

    For example, this module can be used to take the throttle position from a vehicle CAN bus and convert it into an analogue signal to drive a gauge in the vehicle.

    VBOX Legacy Firmware and Software

    With an ever-increasing product range and continuing development of software packages, it is essential that we ensure all firmware files and software downloads are easily accessible from the VelocityBox website. As a result we have recently introduced a dedicated firmware legacy page and will also launch a software legacy page when new versions are released.

    Microsoft discontinuing support for Windows XP - how will it affect you?

    Microsoft has recently announced that their support of Windows XP has now ended. This also means that the Microsoft based developments tools that we use for writing Racelogic software will provide less support for Windows XP environments in the future.  In the light of this we have chosen to not to include XP compatibility in future releases of Racelogic application, setup or configuration software.

    The current released versions of our software, which are all XP compatible, will be frozen and will be made available to download from a software legacy page when new versions are released.
