By
well directed braking actions, ESP is making sure to correct driving faults
causing understeer or oversteer.
Specifically every single wheel can be slowed down and, if necessary,
the engine power is adapted automatically. The braking actions are happening
as fast as lightning and they are lasting only fractions of seconds. The
"brain", steering those interventions, is the main computer.
Therefore, the Audi R&D Team had developed software, called "Dynamic
Stabilization Systems". This program is permanently checking the
actual performance of the car against the given values.
To verify and quantify the different software versions and updates, they
mounted 7 M5 sensors to a car, to conduct different tests.
Afterwards, on the basis of the logged data, a reliable system adjustment
could be made.
"Without the fast and reliable M5 sensors, the results of this test
would haven been conjectural", was the comment of the R&D team
leader.
The M5 sensor is the predecessor of the now available
M7 distance sensor. With
an increased sampling frequency of 54 kHz measurings of fast moving objects can be made.

A sensor, working
on average technique, may be accurate, but not fast.
Vibration and oscillation measurement is demanding for fast, reliable,
accurate and contactless measuring tools.
We have a large assortment of fast and accurate laser sensors, useable
for the most diverse applications.
