Vehicle Dynamics Study

A car is stable on entry but develops understeer at mid-corner in medium- and high-speed turns, costing minimum speed.

1. 01Calculate a balance indicator from steering, yaw rate and lateral acceleration.
2. 02Segment corners by speed band and phase.
3. 03Review ride-height and damper data to understand platform behaviour.

Understeer grows with speed, and front ride height drops further than expected under load — pointing to platform rather than mechanical-balance causes.

• Balance shift is speed-dependent, not corner-type dependent.
• Front platform control is the likely primary contributor.
• Two of four setup directions moved balance toward neutral in the model.

A targeted platform change offers a more consistent mid-corner balance across speed bands.

Splitting balance by phase and speed separates symptoms from causes and narrows the setup search.
