Jorge Jauregui opens a garage
door at Bosch’s winter test centre in Arjeplog, located in the north of Sweden.
His warm breath condenses into wisps of fog. The thermometer reads minus 20°C.
He is a development engineer and has taken out vehicles a countless number of
times on the icy and snowy roadways here, analyzing measurement data and optimising
system calibrations. But today is special: the hypercar behind the garage door
will be driven on a test track just a few kilometres south of the Arctic Circle
for the first time.
The Pagani Huayra BC boasts 12
cylinders and more than 750 hp. Bosch makes its ABS antilock braking system,
the traction control system, and the ESP electronic stability programme. Viewed
from the outside, these electronic guardian angels watching over this
lightweight wonder are no different than the components found in millions of
other vehicles on the road all over the world. But the software in this
application was tailored for Pagani’s small production run, using a unique
configuration of the software in each of the only 20 vehicles produced and five
prototypes. The behaviour of the systems can be adjusted for one of five
stages, ranging from comfort to maximum dynamic handling.
This type of precision
engineering work is the task of Jauregui and his colleagues, who will be
stationed at the test centre in Sweden with one of the prototypes for two
weeks. Although they have already subjected a number of vehicles to extreme
testing under winter weather conditions as a part of these “winter tests”, this
time things are different. As Jauregui says, with a gleam in his eye, “Getting
more than 750 hp under control on the snow is a special challenge, even for me.
It’s not something I do every day.”
Pagani and Bosch
Pagani relies on Bosch for the
driving safety and braking control systems used on its Huayra and Huayra BC
vehicles. “The philosophy of our vehicles is a combination between art and
science, technology and design, performance and uncompromising safety. Bosch
Engineering has been our partner for a number of years now in this endeavor,”
says Horacio Pagani, founder of Italian hypercar manufacturer Pagani
Automobili. Although the ABS and ESP hardware come from Bosch’s mass-production
automotive portfolio, it is Bosch Engineering GmbH, a subsidiary of the
supplier of technology and services, that is responsible for the custom
adaptation of the software. Bosch Engineering employs more than 2,000 engineers
whose expertise extends to every aspect of their field – except off-the-shelf
solutions. As they have already done with the Huayra and the Zonda, the company
is using the Pagani Huayra BC to showcase its ability to tailor and configure
both software and electronics to meet vehicle-specific requirements. Because in
order to perform ideally in all situations, the ABS and ESP systems require
extremely precise software calibration to accommodate both the performance
characteristics of a hypercar as well as the particularities of summer and
winter road conditions.
“This is the only way in which
we can exploit the entire safety potential of the software while creating the
dynamic handling particular to this brand. We understand Pagani’s requirements
in this regard, and are developing a tailor-made software accordingly,” says
Bernhard Bihr, president of Bosch Engineering Group.
Testing day in northern Sweden
For Jauregui and his
colleagues, the days in northern Sweden begin early while it is still dark
outside. Although sunrise is still a few hours away, large floodlights already
illuminate the various road course modules both over land and over parts of the
huge frozen lake. “First we test the ABS on a roadway surface that is iced over
on one side. Later on we see how the car handles on a testing course located on
the frozen lake,” native Argentinean who works for Bosch Engineering for more
than 10 years explains. An electronic stability programme, for instance,
contains over 3,000 parameters in its software that affect the system’s
reactions. “The greatest challenge for us is making all of the vehicle’s power
and handling controllable and safe, even in critical situations, without losing
sight of performance.”
Jauregui’s most important ally
in this task is Jakob Hellkvist, who is an “icemaker”. Working morning, noon,
and night, his job is to prepare the road courses, making sure that the driving
surface conditions on land and on the lake are always the same. Several times a
day, he sprays the roadways and course modules with water and then smooth them
out, after which he will use specialized equipment to give the ice surfaces
exactly the right amount of friction. All of this ensures that even the
smallest changes in handling behavior can be analysed following software
adjustments, and that these changes are not the result of variations in driving
“For us the reproducibility and comparability
of measurement data is very important. We want to be able to measure how the
handling will change when we adjust one of the parameters. When the road
surface is always the same, we can eliminate it as a factor,” Jauregui
explains. His laptop is mounted above the center console of the vehicle. After
every test drive, he checks the measurement values, stores data, enters new
command combinations into the computer, and then starts driving again. He will
keep doing so until this symbiosis of safety and performance of Pagani’s Huayra
BC is perfect, even on ice and snow.
Winter testing in northern Sweden
Bosch conducts winter testing
on its state-of-the-art driving dynamics control systems at its test centre in
Vaitoudden near Arjeplog in northern Sweden. This testing allows engineers to
ensure that safety systems such as ABS and ESP will perform as intended in
every situation to provide maximum assistance to the driver. The new, expanded
testing grounds were officially opened in December 2003 by King Carl XVI Gustaf
of Sweden. The total investment volume totaled 20 million euros.
