When response gets dynamic, confidence drops
ESC and handling tests are run on controlled surfaces, and the challenge is interpreting behaviour when manoeuvres are fast and systems intervene. Steering input, yaw and body motion happen together. If those signals are noisy, delayed, or referenced to the wrong point on the car, cause and effect becomes ambiguous.
A single reference for vehicle motion
Dynamics Duo combines VBOX 4 and IMU05 for a unified centre-of-gravity-referenced vehicle motion measurement. Steering input, yaw rate, slip angle, lateral acceleration and path are all captured on one time base, with low noise and lag, displayed in real-time.
This allows engineers to see the true relationship between input and response so vehicle behaviour and handling balance can be evaluated objectively, without subjectivity.
Accurate Inputs. True Vehicle Behaviour
For handling analysis, measurements must reflect how the vehicle moves at the true centre of gravity.
Dynamics Duo provides:
- Speed referenced to the centre of gravity, unaffected by wheel slip
- Yaw rate and lateral acceleration calculated at the CG
- Accurate vehicle trajectory for path assessment
- Longitudinal acceleration (Ax) to understand braking or lift-off during intervention
This keeps stability analysis tied to the true motion of the vehicle.
Clean Data. More Reliable Analysis
During fast manoeuvres, noisy or biased data makes behaviour hard to interpret.
With low-noise inertial data:
- Pitch and roll are measured during rapid steering inputs
- Yaw rate and lateral acceleration remain stable in aggressive events
- Vehicle rotation is measured without roof-mounted exaggeration
This means conclusions about stability and ESC performance are based on clear, reliable signals.
Clearly Separate Driver and ESC Actions
To tune ESC, you need to know what the driver did and what the system did.
The Dynamics Duo lets you:
- Log steering angle alongside yaw rate
- Compare wheel speeds with vehicle rotation
- Record ESC status and brake signals via CAN
This makes it easier to see whether behaviour comes from driver input or system intervention.
One Reliable Setup for ESC & Handling Testing
From ISO lane change tests to sine-with-dwell and steady-state manoeuvres:
- One installation supports multiple test types
- Alignment is quick, even across vehicle changes
- Real-time feedback confirms that the run is valid
Measure motion once and use it across the full stability programme.
Software to Support ESC & Handling
After testing, VBOX Test Suite lets you overlay runs under identical conditions compare steering and yaw response, visualise slip angle and lateral acceleration together, and export data for review, benchmarking and development.
