1 (X):  Left Wheel Roll Inclination

% (deg/100 deg)

The left wheel camber angle change with respect to the true ground line (line connecting tire patches) due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or:

track = abs((right wheel center y) - (left wheel center y))

deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness)

Orientation A:

roll inclination = 100-(-C(4,3)+C(4,9))*track/deltaz*100

Orientation B:

roll inclination = 100-(C(4,3)-C(4,9))*track/deltaz*100

2 (Y):  Right Wheel Roll Inclination

% (deg/100 deg)

The right wheel camber angle change with respect to the true ground line (line connecting tire patches) due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or:

track = abs((right wheel center y) - (left wheel center y))

deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness)

Orientation A:

roll inclination = 100-(-C(10,3)+C(10,9))*track/deltaz*100

Orientation B:

roll inclination = 100-(C(10,3)-C(10,9))*track/deltaz*100

3 (Z): Average Roll Inclination

% (deg/100 deg)

The mean of components 1 and 2.
