In the
Formula 1 of the future, the use of simulation
techniques will become ever more important and so, after
many years working with the FIAT Research Centre,
Ferrari chose to take the very important step of
building a simulator based on a specification that
places it at the cutting edge in this area.
Marco
Fainello, Head of Vehicle Performance and the design of
the simulator:
Can you
start by explaining what exactly is a simulator?
“Basically, it consists of a Formula 1 car cockpit,
surrounded by images that a driver would see if he was
at the wheel of a real car, including what can be seen
in the rear view mirrors. The cockpit, fitted with
identical controls (pedals, steering wheel and so on) as
used on track, is mounted on a platform which transmits
signals from electronically controlled actuators, which
can reproduce every possible movement in all directions,
thus putting together everything a driver could feel if
in a car. It is impossible to exactly reproduce every
movement of the real car because that would require a
space as big as a real race track: therefore techniques
are used to select and replicate some of these movements
in a way that is compatible with the space available and
that are also useful in terms of getting the driver to
experience some of the sensations he would feel on a
track.”
What does
the driver see when he is in the cockpit? The track
is replicated on a specific computer that uses a
faithful 3D reproduction, including objects found at the
side of the track and in the background, the track
itself, it’s characteristics in terms of kerbs, and the
actual track surface. Furthermore we have imaged data
relative to the position of the sun and shadows that
this creates and we can modify some external parameters,
such as air and track temperature, as well as wind
direction and strength.”
What is
the real scope of a simulator? No driving simulator
is capable of reproducing the real feeling that a driver
experiences in a car: the sensitivity of human beings
and expert drivers such as those in Formula 1, is too
high to create the impression of being in a real car,
when driving on a non-straight course while sitting in a
room. Nevertheless, simulators can provide some
sensations (visual, forces, movement, vibration, noise)
which in some areas are identical, in others are similar
or in others still, are different but close enough to
real ones. This means it is possible to drive a model of
a virtual vehicle, experiencing sensations that can be
referenced to a real one. With a sufficiently
experienced driver and engineers, who analyse the
results, it is possible for a simulator test to produce
data useful to the development of the car and in terms
of how the driver interacts with the handling and the
controls on the vehicle. All of these elements come
together with the advantage of being able to carry out
various tests in total safety, reducing costs in terms
of logistics and equipment, saving time and without
being at the whim of the weather, which can be set and
maintained to whatever one wants. Finally, with similar
results, the simulator reduces the effect on the
environment, compared to a real test, using much less
energy than if the same tests had been carried out on
track.”
Can one
say that the simulator can totally replace on-track
development? Driving simulators can definitely not
replace real track testing, but like many other
calculator-based methods and test benches (in fact, this
piece of equipment is a mix of both these methods) it
can contribute to the design and development process for
new parts that can be used on the car, thus reducing
costs and saving time.”
