2) Speedometer Gauge
The speedometer indicates the vehicle speed by calculating the signals from the rear left and rear
right wheel speed sensors through ABS or ESP unit. (For the vehicle without ABS or ESP, the
signals are received from the EMS)
If the speedometer gauge vibrates, stops at a certain range or makes an abnormal noise, there
could be defectives in speedometer. However, these symptoms also could be occured when th
e
tire has uneven wear, different tire inflation pressures or different tire specifications.
Perform the speedometer test regarding the tolerance as described. However, it is not similar
simple work in field due to lack of measuring conditions such as test equipment and preciseness.
Check the allowable tolerance of the speedometer and operations of the trip odometer by
using a tester.
Check if the speedometer pointer is shaking and the abnormal noise sounds.
Eliminate the hysteresis by tapping the speedometer. 1.

The allowable tolerance increases when the tires are worn or the tire pressure is out of
specified range.

KAMM circle ▶
Before we go into the Kamm circle, you
should know that a tire offers a maximum of
100 % transmissibility. It is all the same for the
tire whether we require 100 % in the direction
of braking or in the direction of the acting
lateral force, e.g. when driving round curves. If
we drive into a curve too fast and the tire
requires 100 % transmissibility as cornering
force, the tire cannot transmit any additional
brake force. In spite of the ABS the car is
carried out of the curve. The relationship
between brake force B and cornering force S
is shown very clearly in the Kamm circle. If we
put a vehicle wheel in this circle, the
relationship becomes even clearer. In this
relationship: as long as the acting forces and
the resulting force remain within the circle, the
vehicle is stable to drive. If a force exceeds
the circle, the vehicle leaves the road.
Brake force
When depressing the brake pedal the brake
force increases to the maximum, then the
brake force decreases until the wheel locks.
Cornering force
The cornering force is a maximum when the
wheel is turning freely with zero slip. When
braking the cornering force falls to zero if the
wheel locks (slip 100 %).
ABS operating range
The operating range starts just before the
maximum brake force and ends in maximum,
for the unstable range then begins, in which
no further modulation is possible. The ABS
controls the regulation of the brake pressure
so that the brake force only becomes great
enough for a sufficient proportion of cornering
force to remain. With ABS we remain in the
Kamm circle as long as the car is driving
sensibly. We will leave driving physics with
these statements and turn to the braking
systems with and without ABS. -
