I was browsing through stuff tonight and I stumbled upon this, it seems like a very interesting and promising new concept in hos suspensions are made. I know there is air ride and all kinds of other stuff which I may or may not be completely informed about but I read through this and I just wanted to know what you guys thought. They have some demo videos and such on there along with a good bit of information.
thats some crazy shit
Whoa
They probably have force-feedback sensors of some kind and a quick computer to pulse the actuators…pulsing the actuator based on force received and roll/pitch/acceleration as well as speed and steering wheel position.
IOW: It’s basically a giant speaker with a really smart computer to drive it based on current input instead of an mp3 player.
Neat!
If I was baller, I’d deffinetly pay for a suspension that good.
Seems like you could easily adjust ride height also, since it is all computer operated.
that’s fuckin nuts. who would have thought bose would make such a thing.
I’m actually co-oping at bose right now. They do a lot of interesting projects. They had a baby bottle that would always keep milk a the right temperature and a similar think with a hot lunch box from what I recall. The techonology is pretty cool.
Here’s a link of a full length video of it. Different language but they do some cool stuff like hoping over a 2x4. Should be interesting when it finally comes out.
You pretty much hit the nail on the head. Works a lot like the noise canceling headphones. You recieve an input wave and are basically creating another wave which is the exact opposite resulting in the waves canceling. Therefore you don’t feel the bump.
How about this: replace the hydraulics on lowriders with this setup to make their cars dance to the music instead of having to program a sequencer or manually using a control box?
man… those things are bumpin
Supposedly it will be one of the most expensive options ever available in a car.
Fortunately technology always gets cheaper, because that is some awesome suspension.
I believe that the University of Texas and a couple individuals in europe are working on the same technology with electromagnet motors. The technology isn’t supposed to come to market for 4+ years, but it will be interesting to see how quickly competitors pop up and what the price range will drop to.
I’m not sure what the weight difference will be. I know it is at least a few hundred pounds more than a current setup, but at the same time there a few other components that you can remove such as the sway bar ect.
dear lord that is rediculous…
I had a friend translate the french version on youtube. Here it is for anyone who is interested.

Since the invention of the suspension, which works with a piston and hydraulics, it is now electronic, seen here with Mercedes. The best compromise between comfort and sportiness. In the united states, we found it even better.
It’s in Boston where we went to find a major invention regarding suspension. Boston is a city on the east coast which is home to Harvard and the famous MIT, the institute of research technology, a city where anything can happen. In Boston is also found the headquarters of Bose, one of the largest specialists in sound. This big name in acoustics also decided to try its hand in a concept of active suspension after 24 years of research.
There is a connection between sound and suspension. Look here for example, at these headphones that filter sonar vibrations, whereas the active suspension filters vibrations in the road.
Demonstration: like you can see, this equipped vehicle stays remarkably stable through braking and it rolls like a magic carpet over the bumps.
Comparing it with a conventional model at the right, we see that the car sways from side to side in turns and that the nose of the car plunges forward when coming to a stop. Another useful comparison with a sports
car: this Porsche provides a suspension less supple. Passing
over these bumps in three cars shows the advantage of the active
suspension. We can also see the difference when the car
turns in a parking lot. The secret comes from this electro-magnetic motor.
“One of the big advantages compared to other technologies is the speed of the motor. The motor is capable of readjusting to a bump in a matter of 1/20th of a second, if not faster.”This kind of invention would never have seen the light of day with out the persistence of Dr. Bose, founder of the enterprise that bears his name. His passion of technology regarding auto suspensions has spanned a long time; he even once drove a Citroen DS.
“It would have been impossible in any other company. I would have been fired a long time ago.”The result is stunning. Even more, the system uses three times less energy than an air conditioning unit.
To give better control through turns, the active suspension can lean to one side like a motorcycle. But keeping the best for last, you saw correctly, the car jumped the obstacle. I hope that like us, you have appreciated this segment.
I saw a design proposal thing similar to that in popular mechanics about 10 years ago, bout time they figured it out.
Leaning into turns and jumping. That is awesome!
couple things…
i thought the caddy magnetic ride was rediculous but this takes the cake.
i know its in the XLR & optional on the STS & SRX…not sure on the other caddys
INFO:
Magnetic Ride Control - electronically-controlled, magnetic-fluid based real-time damping. The system uses four wheel-to-body displacement sensors to measure wheel motion over the road surface and responds by adjusting the shock damping at speeds approaching one millisecond. That’s five times faster than previous “real time” damping systems.
The secret behind Magnetic Ride Control is the magneto-rheological fluid contained in its dampers, replacing traditional mechanical valves. Suspended in this fluid are tiny iron particles that respond to an electromagnetic charge.
The Magnetic Ride controller will activate if needed to help respond to weight transfer, or roll gradient, of the vehicle - for example during braking, by stiffening the damping rate in one or more corners to maintain smooth body motions.
on a sounds cancellation note…
i don’t know if anyone saw it…but gearhead, dirtygeorge & I talked about it may times… there was some japanese company that did a similar sounds cancelling thing with exhaust noise…
forget the exact setup but there was a mic bud in the exhast somewhere that would record the exhaust tone & a chip would process and output the cancellation tone to a speaker & cancel out the exhaust noise
it was SICK
I assume the cancellation wave would be played through your cars stereo system correct? So only if you were sititng in the car you wouldn’t be able to hear it?
I know for the noise cancelling headphones you have to have a closed system (almost like ear plugs/covers) otherwise the cancellation wave is not as effective.
It be pretty cool if you could actually do it externally for the car exhaust but the dispersion of the sound would probably be to much for current technology I’m guessing. Imagine pulling up to someone with a 3" exhaust and being quiter than a stock car ha.
