Perfect Suspension System

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.



My car won't ever be done because I'm insane. That is all.

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.

Pretty cool!
Wow, back to longitudinal torsion bars!!! But am I seeing a 2-piece torsion bar? I'd like to see a close-up of that ...

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.

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.
