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. 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

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.

RepGen is very customizable, allowing results to be produced for virtually any type of automotive test. All created configurations can be saved and easily recalled for future analysis. 

For customers with focused test requirements, we offer dedicated software packages to simplify the test procedure:

• Aquaplane
• Coastdown

• Centreline Deviation
• Brake Testing

Inputs / Outputs

Inputs

• 2x CAN Bus
  Two CAN Bus interfaces are available. The first CAN Bus connections allows data to be logged from RACELOGIC modules such as TC8 and FIM03. The second CAN Bus interface allows you to log up to 16 CAN signals from a different CAN source (e.g. Vehicle CAN Bus, laser height sensors, or steering wheel sensor). VBOX Tools analyisis software is able to load signal data from an industry standard CAN database file (.DBC).
  
  
• Digital Input
  
  Brake / Event Trigger
  By using a physical pressure switch on the brake pedal, a precise 'start of braking event' can be captured. The brake/event trigger input is oversampled to 25 nS for high distance accuracy.
  Log Switch
  A start/stop logging switch allows users to manually choose when they wish to record data.
  
  
• 4x Analogue Inputs
  Each of the four analogue input channels have a dedicated 24 bit analogue converter. Data is recorded from each channel simultaneously to avoid latency between analogue channel data. The name, scale and offset of each analogue input channel can be adjusted using VBOX Tools software to allow sensor calibration and therefore logging of data in standard SI units. The analogue input connector also provides two power outputs that may be used for driving sensors. These are in the form of a 5 V DC isolated supply and an output equal to the VBOX power supply voltage. Log rates can be set to either 100 Hz or 500 Hz.
  
  
• Voice Tagging
  VBOX 3i can record a GPS synchronised WAV audio tag up to 30 seconds long to a time accuracy of 0.5 sec. The recorded WAV file is then logged to the CF card.
  
  
• Power Supply
  VBOX 3i can accept a supply voltage between 7-30 V DC. Low current consumption results in extended battery life.

Outputs

• CAN Bus
  One of the two VBOX CAN ports can be used to output VBOX GPS parameters plus any 12 channels from connected input modules or internal AD channels. The baud rate and CAN id's for these outputs are user configurable.
  
  
• RS232
  The RS232 connector is used for VBOX configuration and output of real-time GPS data. Provides the facility to connect to a radio telemetry system to offer PC monitoring of test data.

• Bluetooth
  VBOX 3i comes equipped with an internal Bluetooth Radio allowing remote configuration and remote output of real-time GPS data to any Bluetooth capable PC or Data logger. The Bluetooth connection is capable of sending data at the full 100 Hz rate.
  
  
• 2x Digital Outputs
  The first digital output is assigned to 'Speed/Distance' with adjustable 'Pulses per Meter' setting, while the second output is a level switch output enabling users to select any one of the logged channels and assign it a threshold value, e.g. output high (5 V) when speed greater than 20 km/h.
  
  
• 2x Analogue Outputs
  Both 16 bit analogue outputs can be configured to output velocity (or other GPS parameters) for use by additional data logging equipment. The voltage output range is from 0 to 5 V DC with a resolution of 76 μV per bit.
  
  
• CF Card
  Data is logged in a space-delimited text format. Recording time dependent on flash card capacity, log frequency, number of channels and logging conditions. Approximately 29Mb per hour used when logging GPS data at 100 Hz; approx. 182 MB per hour total logging capacity. Please note only compact flash cards up to 32 GB capacity are supported.

Applications

Applications

VBOX Mini is a perfect tool for any vehicle testing department as you can carry out a large number of standard tests very simply, with results being shown in real-time.

VBOX Mini does not have vehicle CAN connectivity. If you need to connect to a vehicle's CAN Bus, please refer to our CAN enabled data loggers from the VBOX IISX or VBOX 3i range.

Performance Testing

Using the built in screen you can measure many different types of acceleration test, 0-60, 0-100, 0-100-0, 1/4 mile, 1/2 mile etc. There are also a number of configurable tests, making the unit extremely versatile.

The G-force screens showing your acceleration, braking or cornering force are updated 10 times a second and the maximums can be reset by pressing the RESET button. All of these performance tests are accurate to 0.1s and 0.1kmh as the unit comes with a full calibration certificate.

If you carry out lots of detailed performance tests on different cars, then the VBOX Mini is the right tool for the job, and is used by magazines, TV companies and test departments around the world.

Lap Timing

The VBOX Mini is one of the most powerful lap timers you can buy with the added benefit that you don't need to set up any external beacons.

Because the VBOX Mini knows where you are 10 times a second, you simply drive over the place where you want to set your start/finish line and press a button. It then calculates the direction you were travelling, and draws a virtual line in its memory at 90 degrees and 25m wide. From then on it knows where your lap starts and ends and instantly displays and records this lap time, accurate to 0.1s.

The VBOX Mini comes with a 99 lap memory and stores all laps on the SD card.

In addition there are 6 split lines that can be defined, and the speed at each of these virtual gates can be frozen to examine corner exit speed or apex speed, giving valuable and instant feedback for the driver from corner to corner.

There is also a separate finish line that can be defined so that you can use the VBOX Mini to time slalom runs or sprint courses with separate start & finish lines.

Speed Measurement

Like all other VBOXs, the VBOX Mini measures velocity using the doppler shift technique, which means that the speed output is very accurate. Included is a large speedometer, and also a speed averaging screen.

This is very useful for calibrating speedometers and also checking the speed of the vehicle between two points. The averaging process can be activated by hitting the OK button, by crossing a start line/split line or by using an external trigger (via the Mini Input Module.)

The VBOX Mini comes with a full calibration certificate which is generated on our state of the art GPS constellation simulator.

Analysis Software

The VBOX Mini is supplied with the complete VBOX Tools software package. VBOX Tools has been developed in conjunction with our customers over many years making it very powerful yet easy to use.

With VBOX Tools you can analyse acceleration tests, braking tests, compare and overlay files in the graph screen. You can setup a real-time test with multiple display windows showing g-force, speed, distance etc., alongside a customisable table of results.

You can use the software in real-time mode connected directly to a VBOX, or in post processing mode using the data stored on the removable flash card. For more information, please see the software page.

Circuit Tools software is also included if you are concentrating on driver training and track analysis.

Applications

Applications

VBOX IISX Dual Antenna can be used for a number of different applications:

• Dynamic Tests
  Slip and pitch angles updated at 20Hz alongside speed, distance and acceleration.
• Steady State Cornering
  Slip angle without any drift or correction over time.
• Trailer Angles
  Measure relative angles between two fixed bodies (two systems needed).
• Brake testing
  Having a maximum update rate of 20Hz is still plenty fast enough for brake testing, you don’t quite get the phenomenal ±1.8cm resolution of the VBOX 3i, but for many purposes the ±10cm achieved is more than adequate. The VBOX IISX has a high speed brake trigger input, which scans for a braking event 100,000 times a second.
• Performance testing
  This unit is perfect for all variations of performance testing, the accuracy and quick response of the 20Hz unit gives very repeatable and accurate results, when tested back to back with the VBOX 3i, they are within a few hundredths of a second every time.
• Durability testing
  The lower sample rates of 5Hz and 10Hz make this unit suitable for long term testing where high speed logging is not required.
• Driving line analysis
  The great positional accuracy and 20Hz update rate are perfect for professional level driving line analysis at an affordable cost.

The VBOX Tools software 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.

There are a number of standard test configurations which can be loaded into the software with one button click:

• Brake Testing – distance, time, MFDD, corrected distance, trigger speed etc.
• Acceleration Testing – instantly view speed versus time & distance tables.
• Circuit Testing – extract and analyse lap information.

We offer dedicated software solutions for a number of specialised tests such as:

• Aquaplane
• Coastdown
• Lane Change
• Centreline Deviation

• 2x GPS Antennas
  By utilising two GPS engines configured in a 'fixed baseline RTK setup', true heading, yaw rate, lateral and longitudinal velocity, slip angle and pitch angle can be measured, (slip is measured at the point at which you place the main reference antenna. This can be translated to any point on the vehicle in post processing). How does it work?
• CAN Bus
  Data can be logged from external modules e.g. the Thermocouple Interface or the Frequency & Pulse Counter Input Module. Up to 16 CAN signals can also be logged from a different CAN source (e.g. Vehicle CAN Bus). When logging data from another source, VBOX Tools can load signal data from an industry standard CAN database file (.DBC).
• Brake Trigger
  By using a physical switch on the brake pedal, a precise 'start of braking event' can be captured. This is required to capture true Stopping Distance to the accuracy quoted.

Applications

Applications

VBOX 3i Dual Antenna can be used for a multitude of test applications such as 

• Brake Testing
• Handling & Dynamics (ESC Testing, Aquaplane, Centreline Deviation, Lane Change, ...)
• ADAS & Safety Systems Testing
• Performance Testing (Coastdown, Pass-by-Noise, Speed & Distance Verification, ...)
• and more.

The VBOX Tools software 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.

VBOX Tools is able to load signal data from an industry standard CAN database file (.DBC).

There are a number of standard test configurations which can be loaded into the software with one button click:

• Brake Testing – Using a brake pedal mounted trigger input, VB3iSL will measure braking distance to within ±1.8cm.
• Performance Testing – This unit is perfect for all variations of performance testing, the accuracy and quick response of the 100 Hz unit gives very repeatable and accurate results.
• Acceleration Testing – Instantly view speed versus time & distance tables.
• Circuit Testing - Extract and analyse lap information.
• Dynamic Tests - Slip and pitch angles updated at 100 Hz alongside speed, distance and acceleration.
• Steady State Cornering - Slip angle without any drift or correction over time.
• Trailer Angles - Measure relative angles between two fixed bodies (two systems needed)
• Accident Reconstruction - Log and animate the vehicle's movement in three axis

RepGen is very customizable, allowing results to be produced for virtually any type of automotive test. All created configurations can be saved and easily recalled for future analysis. 

For customers with focused test requirements, we offer dedicated software packages to simplify the test procedure:

• Aquaplane
• Coastdown
• Lane Change
• Centreline Deviation

We also offer complete packages of hardware for specific tests:

• Test and Validation of Advanced Driver Assistance Systems (ADAS)
• Lane Departure Warning - 2cm accuracy combined with calibrated video overlay
• Adaptive Cruise Control - 2cm vehicle to vehicle accuracy
• Collision Avoidance Systems - vehicle to point, vehicle to vehicle
• Blind Spot Detection - Calibrated Video Overlay

Inputs/Outputs

Inputs

 

• 100 Hz GPS / GLONASS Engine
  VB3iSLR features a powerful GPS engine embracing two antennas and capable of providing 100 Hz signal up date rate for all GPS/GLONASS parameters (i.e. velocity, heading & position). Velocity and heading are calculated via Doppler Shift in the GPS carrier signal, providing you with unparalleled data accuracy.
  
  
• 2x GPS/GLONASS Antennas
  All standard parameters like time, speed, distance, and position are measured at the primary antenna. The secondary antenna enables logging of additional channels like slip angle, pitch or roll angle (depending on antenna orientation).
  
  
• 2x CAN Bus
  Two CAN Bus interfaces are available. The first CAN Bus connections allows data to be logged from external RACELOGIC modules such as TC8 and FIM03. The second CAN Bus interface allows you to log up to 16 CAN signals from a different CAN source (e.g. Vehicle CAN Bus, laser height sensors, or steering wheel sensor). VBOX Tools analyisis software is able to load signal data from an industry standard CAN database file (.DBC).
  
  
• Brake Trigger
  By using a physical pressure switch on the brake pedal, a precise 'start of braking event' can be captured. The brake/event trigger input is oversampled to 25nS for high distance accuracy.
  
  
• Log Switch
  A start/stop logging switch allows users to manually choose when they wish to record data.
  
  
• 4x Analogue Inputs
  Each of the four analogue input channels have a dedicated 24bit analogue converter. Data is recorded from each channel simultaneously to avoid latency between analogue channel data. The name, scale and offset of each analogue input channel can be adjusted using VBOX Tools software to allow sensor calibration and therefore logging of data in standard SI units. The analogue input connector also provides two power outputs that may be used for driving sensors. These are in the form of a 5v DC isolated supply and an output equal to the VBOX power supply voltage. Log rates can be set to either 100 Hz or 500 Hz.
  
  
• Voice Tagging
  VBOX 3i can record a GPS synchronised WAV audio tag up to 30 seconds long to a time accuracy of 0.5 sec. The recorded WAV file is then logged to the CF card.
  
  
• Power Supply
  VBOX 3i can accept a supply voltage between 7 to 30V DC. Low current consumption results in extended battery life.

Outputs

 

• CAN Bus
  One of the two VBOX CAN ports can be used to output VBOX GPS parameters plus any 12 channels from connected input modules or internal AD channels. The baud rate and CAN id's for these outputs are user configurable.
  
  
• RS232
  The RS232 connector is used for VBOX configuration and output of real-time GPS data. Provides the facility to connect to a radio telemetry system to offer PC monitoring of test data.
  
  
• USB
  VBOX 3i USB connector can be used for VBOX configuration and to output real-time data at 100 Hz to a PC.
  
  
• Bluetooth
  VBOX 3i comes equipped with an internal Bluetooth Radio allowing remote configuration and remote output of real-time GPS data to any Bluetooth capable PC or Data logger. The Bluetooth connection is capable of sending data at the full 100 Hz rate.
  
  
• 2x Digital Outputs
  The first digital output is assigned to 'Speed/Distance' with adjustable 'Pulses per Meter' setting, while the second output is a level switch output enabling users to select any one of the logged channels and assign it a threshold value, e.g. output high (5 V) when speed greater than 20 km/h.
  
  
• 2x Analogue Outputs
  Both 16 bit analogue outputs can be configured to output velocity (or other GPS parameters) for use by additional data logging equipment. The voltage output range is from 0 to 5v DC with a resolution of 76 μV per bit.
  
  
• CF Card
  Data is logged in a space-delimited text format. Recording time dependent on flash card capacity, log frequency, number of channels and logging conditions. Approximately 29Mb per hour used when logging GPS data at 100 Hz; approx. 182 Mb per hour total logging capacity. Please note that only compact flash cards up to 32 GB are supported.

Parameters

Parameters VBOX 3i Dual Antenna measures the following parameters at 100 samples per second:
Time Position Velocity Vertical velocity Longitudinal velocity Lateral velocity Height	Heading True heading Lateral acceleration Longitudinal acceleration Distance between two cars Centreline deviation	Slip angle Pitch angle or roll angle, depending on antenna orientation Yaw rate Radius of turn

By adding data from an IMU additional benefits can be achieved, such as:

• Logging pitch and roll angle in real time
• Improved yaw rate and slip angle measurement
• Resilience against GPS dropouts

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 RACELOGIC VBOX Input Modules
• or directly from the CAN bus of the vehicle using the RACELOGIC Vehicle CAN Database.
