Slip Calculation

The slips are calculated in the ISO coordinate system as represented below:
Figure 1.


Longitudinal Slip

The ratio between the contact patch longitudinal velocity and the wheel center longitudinal velocity.


Where is the longitudinal slip velocity of the contact point and is the longitudinal velocity of the wheel along .



Lateral Slip

The angle between the lateral slip velocity of the contact patch and the longitudinal velocity vector of the rim.

Where is the lateral slip velocity of the contact point in the ISO coordinate system.
