(3) Maximum brake force
(4) Slip
The brake slip is the difference between the vehicle speed and the wheel circumference speed.
If the wheel locks, the slip is greatest, that is 100 %. If the wheel is running freely and unbraked,
the slip is the lowest, equal to 0 %. Slip can be calculated from the vehicle speed Vveh and the
wheel speed Vw. The equation for this is:
V - V
veh w
S =
V

The braking process cannot be described
sufficiently accurately with the brake forces
calculated. The values calculated only apply if
the wheel is not locked. In the case of a
locking wheel, the static friction turns into
lower sliding friction, with the result that the
stopping distance is increased. This loss of
friction is termed "slip" in specialist literature.
