Driving Enjoyment at the Highest Level: Protected and Supported
The new Mercedes-Benz S-Class has become more intelligent in many areas, and the driving experience reaches new heights. The digital innovations in e.g. MBUX include new features that make driving even more enjoyable and even safer: among them are rear-axle steering with a large steering angle and safety innovations such as the rear airbag. Furthermore - as a new function of PRE-SAFE® Impulse Side – the vehicle body can be raised just before a side impact thanks to the active E-ACTIVE BODY CONTROL suspension. Following further systematic development, the driving assistance systems are a further step towards autonomous driving. Thanks to improved environmental sensors, for example, the parking systems give the driver even better support when manoeuvring at low speed. While visualisation reaches new levels by virtue of integration into the intuitive operation of MBUX.
Can a luxury sedan with a long wheelbase be almost as manoeuvrable and agile as a compact car around town? Yes, if it has all-wheel steering with a large steering angle at the rear axle.
Are more safety innovations even possible in the interior? Yes, as the S-Class demonstrates: The rear airbag for severe frontal collisions deploys from the front seat backrests, extending the protective systems for the two passengers on the outer rear seats.
Can the active E-ACTIVE BODY CONTROL (optional) suspension improve not only comfort, but also safety? Yes, because in addition to the well-proven PRE-SAFE® Impulse Side system, the new S-Class is able to raise the entire vehicle body immediately before an impending side collision. This can benefit all the occupants.
Can the driving assistance systems be improved even further? Yes, in the new S-Class, Mercedes-Benz comes another big step closer to its vision of accident-free driving. The driver is assisted in controlling the vehicle by numerous new or extended driving assistance systems. He/she thereby has a reduced workload in day-to-day situations, and is able to drive comfortably and safely. When danger threatens, the assistance systems are able to help the driver respond to impending collisions as the situation demands, and ideally prevent them. Active Parking Assist and the 360° camera with a new 3D view assist the driver more easily and conveniently than ever before when parking and unparking, or when negotiating tight spaces.
Overview of key features
With five multi-core processors, more than 20 sensors and the use of the stereo camera, the E-ACTIVE BODY CONTROL suspension (optional) responds predictively to different driving situations:
·Fully-active suspension on a 48-volt basis, with very wide variation of handling characteristics in the different driving modes
·The system's control units analyse the driving situation 1000 times per second, and adapt the suspension accordingly
·E-ACTIVE BODY CONTROL regulates the damping and spring forces individually at each wheel, and not only counters body roll, pitch and lift
·In the COMFORT driving mode, ROAD SURFACE SCAN uses the stereo multi-purpose camera (SMPC) to monitor the road surface ahead of the vehicle. The spring struts are then actuated to greatly reduce body movements when crossing road bumps
·In CURVE driving mode the vehicle actively leans into bends. The leaning function and comfortable suspension setup greatly benefit ride comfort, while passengers with a sensitive stomach feel particularly well
·E-ACTIVE BODY CONTROL enables a new PRE-SAFE® function when a lateral collision threatens (see below)
Thanks to rear-axle steering (optional), the S-Class is as manoeuvrable as a compact car. The steering angle at the rear axle is up to ten degrees, allowing impressive manoeuvrability and agility in urban areas. At the same time the handling benefits from a virtual extension of the wheelbase at higher speeds:
·with all-wheel steering and a large steering angle at the rear, the turning circle of the S-Class is reduced by up to 2 metres. This gives the long-wheelbase S-Class a turning circle of less than 11 metres
·This extraordinary manoeuvrability and agility is also achieved by combining the rear-axle steering with a more direct front-axle steering ratio
·Integrated actuation of the steering and brakes makes handling even more precise and stable in dynamic situations
o When opting for this feature, customers have a choice between two variants, one with a rear steering angle of up to ten degrees and one with up to 4.5 degrees
The new S-Class also sets standards where accident safety is concerned:
·With a new function of PRE-SAFE® Impulse Side, Mercedes-Benz has now augmented its measures in the pre-impact phase:
o when a side impact threatens, the vehicle body can be raised by the E-ACTIVE BODY CONTROL suspension (optional) within a few tenths of a second. This directs the impact forces towards particularly resistant structures in the lower area of the vehicle
·The occupant protection measures are derived from many of the innovations in the Experimental Safety Vehicle (ESF) 2019:
o The new rear airbag (optional) is the world's first frontal airbag for the two passengers on the outer rear seats. Its design with an innovative, tubular structure is unique. As a result it deploys especially gently, and in severe frontal collisions it can greatly reduce the loads acting on the heads and necks of the outer rear passengers (for details see next but one page)
o The new, illuminated designer belt buckles (optional) are easy to locate. This makes attaching the seat belt more intuitive
o In combination with the MBUX Interior Assistant, a camera can now be used to detect a child seat on the front passenger seat for the first time. A belt fastening message for the child seat appears in the central display before the driver moves off
o During a severe side impact, the new centre airbag (available depending on country) positions itself between the driver and front passenger seat, reducing the risk of their heads making contact
The latest generation of the Driving Assistance Package has new and numerous improved functions. Two examples:
·Active Blind Spot Assist:
o The exit warning function now gives a warning as soon as the driver or front passenger reach for the door. This is because the MBUX Interior Assistant recognises when a hand approaches the door handle.
o A visual warning is given by a red warning triangle in the exterior mirror and via the active ambient lighting
·Active Steering Assist:
o This assists the driver in forming an emergency corridor, and encourages other drivers to form a corridor as well
Thanks to improved environmental sensors and integration into MBUX, the parking systems give the driver even better support when manoeuvring at low speed:
·Active Parking Assist:
o Improved environmental sensors: 12 ultrasonic sensors at the front and rear, with improved performance
o Newly developed, understandable and simplified user interface, integrated into MBUX, convenient touch control
o The positions of road users and objects can be registered reliably and highly precisely
§ Emergency braking function when reversing
o Integration of the optional rear axle steering, commensurate trajectory planning
·Parking package with 360° camera:
o Extended environmental sensors, now with sensor fusion: Four additional cameras (front, rear, exterior mirrors)
o These enable more parking spaces to be recognised and offered
§ Parking spaces defined by lines (not by vehicles) can also be used for automated parking for the first time
o The four individual camera images are combined into a three-dimensional image of the vehicle's surroundings. This is shown in the central display with dynamic perspectives
o The three-dimensional image can be intuitively rotated around the vehicle as a virtual camera view, and even has a zoom function
o Extended side view: Makes manoeuvring easier near parallel obstacles such as kerbs, garage walls etc.
o Automatic braking for pedestrians either forwards or when reversing if Parking Assist is active
o Collision prevention around the entire vehicle is possible, while complying with the strict requirements of UNECE R79 for automated parking
o Model of the vehicle is calculated in real time
§ Shows the vehicle status (e.g. indicators, braking)
§ Reveals visual obstructions (e.g. open doors, folded mirrors)
