Overview

VBOX 3i uses a powerful GPS/GLONASS receiver logging data 100 times a second to achieve high level accuracy. With IMU integration, USB and Bluetooth connectivity, compact flash card logging and audio functionality for voice tagging, the VBOX 3i represents a flexible solution to a range of testing requirements.

IMU Integration
VBOX 3i has the ability to utilise data from a RACELOGIC IMU and uses a Kalman Filter to improve all parameters measured in real-time. IMU integration ensures accurate test results in areas of unreliable satellite reception, typically caused by trees, buildings and bridges.

The vehicle's body angles are also measured to a high accuracy without the need to use a dual antenna system. Dynamic overshoot is eliminated through lever arm correction.

Accuracy
Velocity and heading data are calculated from Doppler Shift in the GPS carrier signal, providing users with unparalleled accuracy. For example, over 10 tests between two light barriers placed exactly 1000m apart, the VBOX will report a distance within ±2-3 cm, on every test, and the average comes out to within less than 1cm. Impressive for a device using satellites 18,000 km away!

Brake distance accuracy is equally impressive, using a brake pedal mounted trigger input, VBOX 3i will measure the braking distance to within ±1.8 cm for a typical 100-0 kph brake stop.

VBOX 3i comes in three versions, single antenna, dual antenna and (dual antenna) RTK. In conjunction with a DGPS Base Station (Option 1) VBOX 3i Single Antenna can achieve a positional accuracy of 80 cm


IMU Integration
IMU04-with-xyzVBOX 3i has the ability to utilise data from a RACELOGIC IMU and uses a Kalman Filter to improve all parameters measured in real-time. All captured data is processed at 100 Hz, improving accuracy / noise levels and enhancing the dynamic response to velocity.

IMU integration ensures accurate test results in areas of unreliable satellite reception, typically caused by trees, buildings and bridges.

The vehicle's attitude (pitch, roll and yaw angles) is also measured to a high accuracy without the need to use a dual antenna system (roll/pitch at 0.06° rms, Yaw at 0.5° rms). Dynamic overshoot is eliminated through lever arm correction.

Applications
VBOX 3i can be used for a multitude of test applications such as
• Brake Testing
• Handling & Dynamics
• ADAS & Safety Systems Testing
• Performance Testing
• and more.

The VBOX Tools analysis package allows you to carry out sophisticated tests in real-time and in post processing.
All parameters can be viewed in a customisable graph, and the data can be scanned, analysed and manipulated using the very powerful Report Generator function.

For customers with focused test requirements, we offer dedicated software packages to simplify the test procedure:
• Aquaplane
• Coastdown
• Lane Change
• Centreline Deviation
• Brake Testing


Parameters
VBOX 3i measures the following parameters as standard, at 100 samples per second, and purely from GPS/GLONASS:
• Time
• Position
• Velocity
• Heading
• Height
• Vertical velocity
• Lateral acceleration
• Longitudinal acceleration
• Radius of turn
• Centreline deviation
By adding a RACELOGIC Inertial Measurement Unit (IMU), you can also measure...

• Pitch angles
• Roll angles
• Yaw angles
...at 100 Hz.

Many other external parameters can be logged, either:
• by using the four high resolution analogue inputs built into the unit
• from a number of versatile VBOX Input Modules
• directly from the CAN bus of the vehicle using the RACELOGIC Vehicle CAN Database.
