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. 

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.

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. 

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.
