THE DYNAMICS DUO
Measuring Motion
Our Dynamics Duo, VBOX 4 and IMU05, provides a single, consistent reference for vehicle motion, supporting accurate, repeatable results under real test conditions.
Ensuring Data Integrity
Inconsistent test entries and uncontrolled driver inputs often compromise data integrity before a manoeuvre even begins. When engineers cannot separate true vehicle behaviour from variables such as pedal force variation or inconsistent entry speed, valuable track time is lost on results that cannot be reliably compared or explained.
When vehicle motion becomes complex, confidence in the data depends on a measurement reference you can trust. By combining the VBOX 4 dynamics GNSS data logger with the IMU05 inertial measurement unit, VBOX Automotive provides a single, integrated measurement foundation designed to reduce uncertainty.
Together, they form the Dynamics Duo: an easy-to-deploy system that enables fast, consistent testing, provides immediate confidence in each run, and delivers cleaner data for reliable post-test analysis.
Why Dynamics Duo?
The Dynamics Duo is engineered to tackle your challenges head-on.
Cleaner Data. Greater Confidence.When IMU05 is used in conjunction with VBOX 4 Dynamics: - GNSS-based measurements become significantly more noise-free - Data remains reliable in less-than-favourable GNSS environments - Inertial measurements bridge gaps where satellite visibility is compromised The result is smoother signals, more stable outputs, and data you can trust – lap after lap, test after test. 
Live Visibility. Instant Validation.See exactly how the vehicle performs as it happens. With real-time data streaming and live results in VBOX Test Suite, you can validate every run while still on the track. - Instantly verify if entry speeds, pedal force, or steering rates met the test protocol. - Reduce Costly Retests: Identify inconsistent runs or driver-influenced outliers immediately. - Decisions can be made trackside, saving valuable development time From high-speed braking to complex dynamic handling, the Dynamics Duo keeps you connected to the metrics that define a successful test day. |
True Vehicle Dynamics, Measured DirectlyThe Dynamics Duo doesn’t just improve existing measurements, it expands what’s possible. Engineers gain accurate, repeatable measurement of key vehicle dynamics parameters, including: - Pitch angle - Roll angle - Body heading angle - Slip angle These are delivered directly from the combined GNSS and inertial solution, without estimation, complex post-processing, or additional sensor integration. 
Fast Setup. Efficient Test Days.Ease of use is fundamental to the Dynamics Duo: - Fast installation and simple configuration - Intuitive software and workflows - Minimal setup time, maximum test time Whether in proving grounds, public roads, or challenging real-world environments, the system works the way test engineers expect it to. 
One Platform. Deep Analysis.Beyond core GNSS and inertial measurements, the VBOX ecosystem allows engineers to: - Capture a wide range of vehicle data not natively measured by VBOX or IMU - Integrate CAN, analogue, digital, and third-party sensors - Synchronise all data streams with absolute time accuracy This creates a single, coherent dataset – no guesswork, no manual alignment, no compromises. |

What Engineers can measure
The Dynamics Duo delivers the measurements required to assess performance, stability and vehicle behaviour using objective, reproducible parameters.
Braking & Longitudinal PerformanceUsed across brake, ABS and tyre-related testing, align directly with UNECE, FMVSS, ISO and OEM protocols: - Stopping distance and time to stop - Mean Fully Developed Deceleration (MFDD) - Brake event timing (brake application, deceleration build-up, ABS entry) - Longitudinal deceleration profile (Ax vs time or distance) - Vehicle speed at defined distance or time gates Driver & System InputsVehicle and system signals correlated with motion data to support deeper analysis: - Brake pedal force or position (external sensor or CAN) - Brake line pressure (external pressure sensor or vehicle CAN) - Wheel speeds (vehicle CAN or external sensors) - Longitudinal deceleration profile (Ax vs time or distance) - Brake temperature (external sensors) |
Stability & Control BehaviourUsed across ESC, handling and stability testing to assess vehicle response under changing conditions, asymmetric grip and control intervention scenarios: - Yaw rate and yaw response - Lateral acceleration (Ay) - Brake event timing (brake application, deceleration build-up, ABS entry) - Longitudinal deceleration profile (Ax vs time or distance) - Vehicle speed at defined distance or time gates Vehicle Motion (CG-Referenced)Parameters describing the motion of the vehicle centre of gravity, independent of wheel behaviour, braking system response or driver interpretation: - True vehicle speed vs distance - Longitudinal acceleration / deceleration (Ax) - Vehicle position and trajectory |
A Motion Reference That Fits the Test
The Dynamics Duo provides a single, consistent motion reference that acts as the core measurement for vehicle dynamics testing. It also integrates seamlessly into established brake and stability workflows where procedures and validation criteria already exist.
Engineers can work within familiar processes, with the confidence that results remain consistent, defensible and suitable for validation, sign-off and comparison against recognised standards such as UNECE and FMVSS.
