Driving comfort is a classic Mercedes area of expertise. One of the most important innovations of recent times was the world’s first actively controlled suspension system, Active Body Control ABC, which was introduced by Mercedes-Benz in the CL coupe in 1999.
The system reduces body vibrations caused by bouncing and rolling movements when cornering or pitching movements when braking. The ADVANCED AGILITY package made its debut in 2007, when it appeared first in the new C-Class. The package offers two shifting modes: Sport and Comfort. As part of these shifting programs, each wheel has its own shock absorber with an infinitely variable electronic control.
In 2007 Mercedes-Benz also unveiled the revolutionary PRE-SCAN chassis, which it presented in the F 700 research vehicle. The system can register road conditions in advance, react very sensitively to bumps and potholes, and compensate for them more effectively than other chassis. The PRE-SCAN chassis uses two laser sensors in the headlights as “eyes.”
The MAGIC BODY CONTROL chassis that Mercedes-Benz presented in fall 2010 is an advanced system that literally looks ahead — a highly sensitive stereo camera mounted on the windshield, above the rearview mirror, “observes” the road in front of the vehicle from two different perspectives, enabling the system to recognize uneven road surfaces in even greater detail. Fast onboard computers process all of the data in real time and control the active ABC chassis, which can adjust the forces at each wheel separately. This allows the vehicle body’s movements to be largely compensated for, compared to those of today’s standard chassis.
