- Automated wheel speed calibration procedure
- Free analysis software with plugins for Lateral and Longitudinal aquaplane testing
- Simple to set up and easy to use
Highly Accurate
The VBOX provides high accuracy speed, position and heading data, and is the industry standard measurement tool when it comes to tyre testing and vehicle dynamics.
Free Data Analysis Software
VBOX Test Suite is free to all VBOX users and comes pre-installed with dedicated Lateral and Longitudinal analysis plugins, to speed up the testing process.
Wheel Speed Calibration
Automated wheel speed calibration procedure to simplify system setup in Longitudinal Aquaplane or Tyre Traction tests.
Live Display
VBOX Test Suite installed on a Windows device within the test vehicle offers real-time display of all measured parameters.
Reduce Test Time
You can see if your system has passed or failed the test in real-time, by easily configuring your own pass and fail criteria in the software, which can reduce post-processing time.
Map Integration
Overlay a positional trace onto a satellite image to help better understand the testing environment.
Lateral
As test entry speeds increase, the lateral acceleration obtained will also increase. However, once the vehicle starts to aquaplane the acceleration values begin to decline.
By closely monitoring the vehicle's lateral acceleration throughout the test procedure, the Lateral Aquaplane plugin produces a comprehensive report outlining in detail the maximum acceleration obtained and how quickly, and to what degree, this value decreases when the tyres begin to aquaplane.
This data can be directly compared to other tyre compounds to provide you with the information you need to grade tyre performance in wet corner conditions.
Longitudinal
The VTS Longitudinal Aquaplane plugin can be used to denote a threshold slip value for each wheel, providing you with the opportunity to choose between reaching the aquaplane condition when one, or all of the tyres, exceed this value.
It provides the ability to set pre-entry test conditions in order to ensure the vehicle is in a steady state before the test begins, and automatically calibrates wheel speeds simply by driving at a constant speed - removing the restraints of having to calibrate within the test area.
Testing Equipment
A typical Aquaplane test setup consists of a VBOX 4 data logger available with a choice of single or dual antennas. When integrated with a VBOX Inertial Measurement Unit (IMU), the system can be used to accurately measure pitch, roll and yaw rate.
Measured Parameters
- Vehicle speed (0.1 km/h RMS)
- Distance accuracy 0.05 % (<50 cm per km)
- Heading resolution (0.01°)
IMU Integration:
- Pitch and roll angle (0.06° RMS)
- Yaw rate resolution (0.00085°)
Powerful 100 Hz Data Logging
VBOX 4 is the pinnacle of the VBOX product range. It uses a powerful GPS/GLONASS receiver and logs data 100 times per second, to achieve high level accuracy.
Tablet or PC for live data display
Want to save time analysing your data? Let VBOX Test Suite do it for you. Our free data analysis software comes with dedicated Aquaplane plugins, and shows you live data from your vehicle in real-time, allowing you to review tyre performance instantly.
Video Integration
A VBOX video logger can be used to simultaneously log data and graphically enhanced video.
Graphical overlay is totally user configurable and can be easily altered to present relevant information according to the tests being conducted.
