Magneti Marelli's technological contribution to innovation
and safety with the CDC (Chassis Domain
Control) control unit and with front and rear lighting, infotainment,
suspensions, exhausts and engine control components.
The
Queen of the Frankfurt Motor Show, the new Alfa Romeo Giulia Quadrifoglio, has
adopted distinctive technologies designed in conjunction with Magneti Marelli.
Magneti
Marelli is making an important contribution, first and foremost within the area
of electronic systems: at
the forefront is the CDC (Chassis
Domain Control) electronic control unit, the "brain" of the car, and
the new infotainment system equipped
with an 8.8 "black panel" TFT (Thin Film Transistor) display which
integrates innovative "optical bonding" technologies designed for
perfect display readability.
The CDC is the electronic control unit
developed by Magneti Marelli that represents the "brain" of the
on-board electronics and optimises handling and performance.
Specifically,
the CDC is a "supervisor" which adapts the car set-up dynamically and
in real-time, based on the data from inertial sensors that measure the
vertical, lateral and longitudinal accelerations and rotation. The system
anticipates and manages critical situations, informing in advance the specific
control units involved in the electronic system through the vehicle networks.
The
CDC control unit increases driving comfort and safety by predictively adopting
control and management protocols that coordinate the action of the
Alfa DNA, of the Torque Vectoring (the system that allows the rear
differential to separately control the torque for each wheel), of
the Aero Splitter (the
electro-mechanical system that dynamically manages the downforce, which is the
aerodynamic force that enables car road grip, and of the Active Damping Control (adaptive electronic suspensions), as
well as the control of the stability, the chassis, the braking system, the
steering and the driving assistance.
Again
in the context of electronic
systems, Magneti Marelli has developed for the Alfa Romeo Giulia
Quadrifoglio the multimedia infotainment system and
the Connect 3D navigation system with an 8.8" total black "TFT
display". The system uses Genivi open source technology and responds to
automotive performance and robustness criteria. Based on Linux language, it
integrates the connection with the electronic control network of the car.
Aiming at the objective of the "connected car", the Alfa Romeo Giulia
infotainment system offers a sophisticated set of features and functionalities
including the features of media player, navigation system and the management of
vehicle parameters. The heart of the system is a latest-generation HMI (Human-Machine
Interface) developed with HTML5 programming language where management of the
system primarily takes place via the Rotary Pad and through the 8.8" TFT
display on the car dashboard.
Navigation
is characterised by high-resolution maps with 3D and high-speed elements for
the calculation of routes and by Dead Reckoning technology that even follows
the route in areas not covered by a GPS signal. The 8.8" TFT display also
shows the vehicle settings, the diagnostics, the parking assistant control,
highlighting the type of set-up associated with the Alfa DNA, and interaction
with the CAN network for the collection and exchange of data.
Moreover
the display is fully integrated within the design of the dashboard, thanks to
the innovative optical construction of the clear black plastic mask that is
coupled with the TFT display through a process of "optical bonding".
This procedure consists of a peculiar bonding of two surfaces which, allowing
more effective filtering of the light, results in increased brightness and
readability of a display. This technology thus provides a "total
black" curve mask that is aesthetically harmonised with the car dashboard.
In practice, from the user's perspective, the image of the display appears on
the surface of the dashboard with an excellent level of viewing and contrast.
With
regard to lighting systems, Magneti Marelli has collaborated with
Alfa Romeo to produce the headlamps and headlights of the Giulia, distinctive
and characteristic design elements of the car. The Giulia Quadrifoglio
headlamps are made with Xenon technology equipped with AFS (Adaptive Frontlight
System) technology and with a 35W lighting module, a solution that increases
the lighting capability by 200% compared to standard halogen headlamps, thus
ensuring greater safety when driving. The LED technology is adopted for
position lights, DRL (Daytime Running Light), cornering lights and for the
indicators. The LED rear tail lights, a synthesis of stylistic and
technological excellence, identify the rear of the car uniquely and
distinctively, further enhancing the straight and dynamic line of the car.
There
are also many technologies in the other powertrain areas. The 510 hp 6-cylinder petrol 3.0 engine with twin
turbo-charger in fact has a motorised throttle and intake manifold manufactured
by Magneti Marelli. Magneti Marelli also produced the components of the front
and rear suspensions, the exhaust system, the pedal board and the plastic parts.
A Magneti Marelli corner will be present within the Alfa
Romeo stand at the Frankfurt Motor Show where the functions of the infotainment
system of the Alfa Romeo Giulia Quadrifoglio will be demonstrated.
