The table above is a continuation of the previous indicating the relationships for the friction-related accelerating and climbing ability for a vehicle equipped with an all-wheel drive system.
Presuming that that the wheel resistance coefficient is much smaller than the coefficient of friction (fR<<μ) the following is applicable:

Eq. 3-44

The following relations are obtained for driving limits in the plane:

Eq. 3-45

Eq. 3-46

and:

Eq. 3-47

Eq. 3-48

where FZ f stat, 0, FZ r stat, 0=statistic axle loads in the plain.
