I'm sure that all of you out there are familiar with the inherant problem with suspension systems. In order to get better handling you have to stiffin up the ride and sacrifice ride quality. I'm sure everyone here has heard of the BOSE company and their sound technology. What I'm sure you didn't know is that Mr. Bose himself has been spending the last 16 years solving the issue of car suspension. He has developed a system with high speed electronic motors on each shock that are wired into a computer that reacts virtually instantaneously in order to move the shocks when it hits a bump or you take a turn going fast. On top of that because the shocks can adjust fast enough bumps in the road might as well not exist. The only trade off is what comes out of your wallet. It won't be consumer ready for four more years, but when it is it will no doubt be rediculously expensive. The point is that in the not that distant future higher end cars will start using something like this, and once the technology becomes used more it will become cheaper and trickle down and become something that could be available to anyone.

Someone already posted about this, plus that thread had links to video footage demonstrating different cars equipped with the suspension system. It was pretty cool.

Cadillac already has a system in production that uses a magnetic fluid in the shocks and a set of electro magnets coupled to the car computers to adjust ride on the fly.

Much simpler than the Bose system.

Works very well.

I'm not familiar with the Cadillac system, but this Bose system basically keeps the car level at all times. They show the car doing slaloms at full speed side by side with the same car on stock shocks and the one with the Bose system barely sways at all while the regular car sways like crazy. And because all 4 wheels are on the ground, it performs much better.

**EDIT**

Here's the link to the Bose Suspension, and there are quicktime movies that demonstrate the system. Very amazing.

so it wont be ready for 4 more years?? good, thats probably how long it will take people to save enough money for it

thats all well and good but as you said it will sure ding your wallet but maybe not as much as one would think.

and in those vids even though it is impressive the driver of the non bose car would jerk the car to accentuate the effect, very hard to notice but something in most of those videos seemed ...off, I really liked the speed bump and manhole thing cause I deal with lots of those. Everytime the trepid goes over a manhole cover that is slightly resessed I cringe as it makes the car hop pretty bad.

****, where else was it posted? How could I have missed that.

I thought it was already out I saw it on well this website with the Lexus LS400 that had the suspension installed on it

That's pretty impressive. I don't know if I'd want it myself though. I'm not a huge fan of an excessive amount of gadgetry, and, as much as this works well, it seems like a gadget. If nothing else, it'll be expensive when it breaks down.

This was first used in Formula 1 in the early 90s (maybe late 80s). This 'Active Suspension' (AKA adaptive damping) reads what happens to the FRONT suspension and translates it to the rear in anticipation, Front bumps are still felt but the rear is not. This suspension was outlawed in F1 subsequent to the death of Ayrton Senna on May 1, 1994 in the San Marino Gran Prix at Imola. While active suspension was eventually downplayed as a factor in the crash it has never returned to F1

I dont think that it is the same with the BOSE suspension it is still an active damping suspension but the BOSE suspension works independently I believe it reads the road fast enough to compensate without the driver feeling a thing

HOW then does it read it?

It is simply being able to react fast enough. The suspension has to be able to move in order for it to react, but in this system it picks up the tiniest movement and begins compensating imediatly for it. The principle is that you aren't going to feel movement of say a milimeter so as it just has to be able to react fast enough to keep the movement within a cirtain tolerance level which isn't noticable to the driver/passengers.

it can prob' sense a bump during the first few miliseconds of it and adjust accordingly, and as for the cornering which is a gradual motion it shouldnt have a problem making changes on the fly.

Not sure exactly how it works though.

I don't know how the Bose system works, but the GM system, I kinda understand. There are sensors in the car that can tell car movement, position, speed, all that kind of stuff. Meanwhile, the shock absorbers in the car have tiny metal particles in the fluid. A computer in the car takes the information of the sensors, and sends a varying electrical charge to the shock absorbers, which changes the position of the metal particles, and therefore the viscosity of the fluid. Thus, the stiffness of the shock absorbers are changed, apparantly 60 times a second. I've seen a comparison of a Z51 Corvette, and one with the magnetic shocks, and the differance is noticeable, in ride, at least. A bump that would send the Z51 airborne (admittedly, Z51 is fairly hard), the magnetic shocks took with little change in stability. However, there is a noticeable preformance tradeoff.
I don't know if the Bose system works the same way, though.

Sorry pal,

That dog won't hunt. IF it senses a movement of 2mm and then begins to compensate and the size of the bump was only 2 mm it would CREATE more of a bump feel by compensating than was there. Sorry if my engineering mind doesn't grasp this one.

I don't know the specs on how precise it actually is, since bose doesn't release information like that usually. No it is nothing like the GM system, they are electrical motors. If you don't buy my explanation go to the Bose link and read for yourself.

My guess is it has more to do with keeping a consistent (not constant) pressure than it does with wheel travel - though the two are somewhat related. Don't know how they'd compensate for a pressure change that fast but I guess if I knew I'd be the millionaire ...!
