1 (X): Left Braking Force Steer

deg/g

The left wheel change in steer angle induced by vehicle braking.  See brake dive/lift above for calculation of intermediate terms.

Orientation A:

tfs = rtod*weight*(C(6,3)*aczleft+C(6,9)*aczright+

acx*(C(6,1)-slr*C(6,5))+acx*(C(6,7)-slr*C(6,11)))

Orientation B:

tfs = rtod*weight*(C(6,3)*aczleft+C(6,9)*aczright+

acx*(-C(6,1)+slr*C(6,5))+acx*(-C(6,7)+slr*C(6,11)))

2 (Y): Right Braking Force Steer

deg/g

The right wheel change in steer angle induced by vehicle braking.  See brake dive/lift above for calculation of intermediate terms.

Orientation A:

tfs = rtod*weight*(C(12,3)*aczleft+C(12,9)*aczright+

acx*(C(12,1)-slr*C(12,5))+acx*(C(12,7)-slr*C(12,11)))

Orientation B:

tfs = rtod*weight*(C(12,3)*aczleft+C(12,9)*aczright+

acx*(-C(12,1)+slr*C(12,5))+acx*(-C(12,7)+slr*C(12,11)))

3 (Z):  Average Braking Force Steer

deg/g

The mean of components 1 and 2.

4 (RX): Left Braking Force Windup

deg/g

The left wheel change in caster angle induced by vehicle braking.  See brake dive/lift above for calculation of intermediate terms.

Orientation A:

tfs = rtod*weight*(C(5,3)*aczleft+C(5,9)*aczright+

acx*(C(5,1)-slr*C(5,5))+acx*(C(5,7)-slr*C(5,11)))

Orientation B:

tfs = rtod*weight*(-C(5,3)*aczleft-C(5,9)*aczright+

acx*(C(5,1)-slr*C(5,5))+acx*(C(5,7)-slr*C(5,11)))

5 (RY): Right Braking Force Windup

deg/g

The right wheel change in caster angle induced by vehicle braking.  See brake dive/lift above for calculation of intermediate terms.

Orientation A:

tfs = rtod*weight*(C(11,3)*aczleft+C(11,9)*aczright+

acx*(C(11,1)-slr*C(11,5))+acx*(C(11,7)-slr*C(11,11)))

Orientation B:

tfs = rtod*weight*(-C(11,3)*aczleft-C(11,9)*aczright+

acx*(C(11,1)-slr*C(11,5))+acx*(C(11,7)-slr*C(11,11)))

6 (RZ):  Average Braking Force Windup

deg/g

The mean of components 4 and 5.
