Driving innovation
It takes courage to drive innovation forward. It
takesasense of responsibility and know-how.
And it takes a sense both of timing and of what the
motorist expects of a car in the future.
At the end of the 1990s, all these factors came
together in Active Steering. The idea was not new
at that time. An American professor had already
patented the principle in 1990, but the time was not
ripe for the development of an innovation from this
idea. During development work for the new BMW 5
Series, all the factors fell into place that determine
when new technologies of benefit to the customer
should be introduced. One of the tasks of the BMW
innovation management is to constantly monitor
these factors.
In 1999, the Active Steering project was imple-
mented. A team of mechanical and electrical engi-
neers got together to form the core development
team.Test models were designed, constructed, tested
and refined. The challenge was how to enable the
driver to learn intuitively about the new possibilities.
How strongly and when should Active Steering inter-
vene? How much correction does a BMW driver con-
sider beneficial? And how much is sensible?
Strictly scientific measuring methods provided
the basis for the initial application program developed
by BMW engineers. The application program is the
core of the Active Steering system, with which the
BMW Group again demonstrates its technological
lead.
In order to further advance the innovation, experts
from all the relevant disciplines were consulted. For
example, a team of psychologists from Würzburg
University studied how a driver would react in the
worst possible case – the failure of Active Steering in
a random motoring situation. If he were simply to
notice that the system has cut out then the driver
would cope. However, if he were alarmed, he might
react faultily. An entire series of tests with very dif-
ferent types of drivers showed unequivocally that
every theoretically possible system failure lies well
below a danger threshold.
