Mercedes Active Body Control To Go 'Magic' in Next Generation

[Wolfgang]

Dieter Zetsche dreams of flying cars

What is the future of the car? Dieter Zetsche, Daimler chief, is certain:
In 125 years vehicles will no longer drive on the street, but in the air.
And soon the driver can take a nap - the boss tells Stern.

^^Wolfgang, your avatar is very appropriate for this topic as well. LOL

Could somebody please "shed some light" on the BOLD phrase? See picture is that the steel coil spring inside the AIRMATIC DC unit they refer too?


Driven: Mercedes-Benz Magic Body Control - Car News
This “magical” technology relies on a forward-scanning camera to anticipate road imperfections. Car and Driver.

"Mercedes' current ABC system uses a hydraulic piston to act on each steel coil spring to quickly and independently adjust the suspension on each wheel in reaction to the road surface, and it does a fine job keeping the ride smooth and occupants unjostled. But the key term there is “reaction”—the suspension deals with the bumps after the wheel has encountered them. What if the car knew what was coming in advance, with absolute certainty and down to every imperfection? The oil flow at each corner could be
adjusted so accurately that any surface flaw could be practically neutralized."

In this video it is interesting to see (driving a Rolls-Royce Ghost) how the laws of physics and suspension movement apply to the car's occupants. See the guy sitting in the left - rear seat especially

The picture you included is incorrect, since it shows an Airmatic strut (the less expensive option, also used on the GL for example). An ABC strut can be actively controlled hydraulically.

Thanks Wolfgang!

Ah, I see. So the strut includes a steel coil and air spring - the latter at the top (if I am correct?)

OR is the coil steel springs chamber filled with air (adaptive air suspension) also?

 

[Wolfgang]

No air on top, just oil. There might be some air in the damper at the bottom.

Thanks again! Fully understood from the last cutaway sketches

Ingenious damper indeed!

I am sorry that I came so late to the discussion, I want to ask a question regarding ABC that I suppose has been asked and answered.

First I believe firmly that a coil spring delivers the most accurate in suspension control and that is why Super cars are fitted with coils i.e. Bugatti Veyron, Ferrari, Zonda, Aston and the SLS etc.

Now in my books the ABC strut assy. is brilliant - wrapping a coil spring in a rubber casing with a piston and actuator on-top and manipulating the damper and rebound rates accordingly

My question: Why didn't M-B use ABC on the SLS?

Haha, wtf.

I just wanted to make a case in point for the ABC, this suspension system really 'moves' me, the best IMO.

From Car and Driver:

We also were told that the technology was not created by a supplier and Mercedes will not offer it for sale or licensing. The brand, however, is considering offering the regular, non-magical ABC suspension to competitors.

BMW & Rolls-Royce would certainly benefit 101% from this opportunity

Same goes for the Borg's products i.e. Audi (sedans, coupes), Porsche, Bentley. Adaptive air suspensions does not impress me at all, the ABC from Daimler reigns supreme.

Because it's heavy, quite large in terms of space needed, and also eats some horsepowers for the active struts to fight bodyroll.

It's absolutely not something you can see, in it's current stance, on a true-blood sportscar, or on a small car for that matter.

But it's the perfect system for a luxury barge.

Thank you Coolraoul

Yes, I just have to stop being lazy and read I read in the press release about the Magic Body Control about the space taken up etc. Also that the
M-B engineers are working on a more compact system.

Normal ABC is a must for RR, BMW 7er, Bentley, A8 & A6 and even the Panamera could benefit from ABC. Here COIL is the magic word, whilst dropping AIR for better control whilst driving in a sporty manner.

I thought so! I was just testing the water

Lol. I have no idea what was going on in that. I figure that guy (or should I say, kid?) is the owner? Seems a gleeful bunch, unaware of how they appear to those outside of the confines of that gorgeous car. I guess cruising around in a Ghost would make me act the same way! Lol.
