MercedesBerater Posted February 6, 2016 Share Posted February 6, 2016 Silly Bose..... that's old hat even GM has a production semi-active suspension. Google or YouTube ABC suspension, or check this out- http://www.motorauthority.com/news/1092532_mercedes-details-2015-s-class-coupes-curve-tilting-function Quote Link to comment Share on other sites More sharing options...
Quiet_Hollow Posted February 6, 2016 Share Posted February 6, 2016 even GM has a production semi-active suspension. Where do you think Delphi got the idea from? Commercial flop for Bose? Arguably so. Game-changing research in the field of dynamic systems & control? Absolutely. 1 Quote Link to comment Share on other sites More sharing options...
MercedesBerater Posted February 6, 2016 Share Posted February 6, 2016 Right, but what I meant was companies have had these systems since early 2000's. And in 2004 is when Bose announced they had secretly been working on this project. Good on Bose trying to create something.... Maybe they should just focus on speakers. Perfect that first Quote Link to comment Share on other sites More sharing options...
Woofers and Tweeters Posted February 7, 2016 Share Posted February 7, 2016 I don't see anyone else's suspension bumping a 2x4....or spike strips.. Quote Link to comment Share on other sites More sharing options...
wvu80 Posted February 7, 2016 Share Posted February 7, 2016 (edited) There's more to the story, there has to be, it looks too good to be true. A suspension that good would be worth a fortune to any off road racer or rider, car, truck or motorcycle.

The first Race Motorcycle parts that I made weighed pounds rather than oz. It adds up. Quote Link to comment Share on other sites More sharing options...
jason str Posted February 7, 2016 Share Posted February 7, 2016 I don't see anyone else's suspension bumping a 2x4....or spike strips.. The difference looks to be the way it was implemented more than anything, GM's suspension can do the same thing its just they probably don't want it to for safety reasons.

Quiet_Hollow Posted February 7, 2016 Share Posted February 7, 2016 There's more to the story, there has to be, it looks too good to be true. The failure modes of a fully-active suspension are typically spectacular and catastrophic. The systems employed in cars of the last decade are a cost/safety compromise.

I want a suspension that will leapfrog me in front of the Darwin Award candidate who is stopped and texting at a green light....Better yet, leapfrog me over the ones coming head on. 1 Quote Link to comment Share on other sites More sharing options...

Just install a beefy hydraulic suspension similar to the ones the low riders use. Quote Link to comment Share on other sites More sharing options...
Audio Android Posted February 9, 2016 Share Posted February 9, 2016 Cool video, never knew or have seen this before from Bose....The Bose ride for truck driver seats is a great invention..Here is to their happy asses .... The GM suspension is the Delphi system, MagnaRide. It's so good Ferrari uses it on the F12... Quote Link to comment Share on other sites More sharing options...
NBPK402 Posted February 9, 2016 Share Posted February 9, 2016 (edited) When I was stationed in the UK between 1978, and 1981)... Rover used to advertise their active suspension too. The commercial I remember was the car (a sedan that they were also using at the time as a Police Car) was heading toward a cliff and a tire blew ( or something that might cause you to lose control or go off the cliff), and the car continued on as if nothing ever happened, and avoided going off the cliff.

The failure modes of a fully-active suspension are typically spectacular and catastrophic. The systems employed in cars of the last decade are a cost/safety compromise. How so? How would it be anymore catastrophic than a leaf spring breaking? Or a coil spring breaking or coming out of its cup? Or a strut bending or breaking? I rarely see failures of the suspension, it's typically with the pump output pressure. Most failures are with rather simple air ride suspensions.. As the bellows rupture or leak.

Quiet_Hollow Posted February 10, 2016 Share Posted February 10, 2016 Via hydraulic or electronic failure. Which in a fully-active system, like the Bose depicted, not only terminates any damping capability, but also ride height. Critical to maintaining any semblance of control. For compare, when adaptive systems like Magnaride and other similar implementations fail, damping is only partially impaired and ride height is fully maintained. One of the single biggest hurdles in the adaptation of high performance linear actuators by industry is not how they perform, but rather how they fail.

Quiet_Hollow Posted February 10, 2016 Share Posted February 10, 2016 (edited) Active suspension (a form of hydraulic control) is not new and has roots dating all the way back to the industrial revolution. Popularity in vehicular applications, like everything else, stems from the progressive reductions in cost and packaging. What's not shown in the videos is the interior of the cars laden with so much telemetry and sensory gear that the driver hardly has any room. Yes, this stuff was very hot in the 90's...along with Pamela Anderson and Cindy Crawford. Edited February 10, 2016 by Quiet_Hollow Quote Link to comment Share on other sites More sharing options...
