Track width
Also: wheel separation, axle track
The effective lateral distance between left and right wheel contact paths.
Differential-drive yaw estimation uses effective track width, which may differ from a ruler measurement because of compliance and scrub.
- Units
- metre (m)
Example A larger track width produces less yaw for the same left-right travel difference.
Common misconception Nominal wheel-center spacing is not always the best calibrated kinematic value.
