Aurais-tu plus de détails?
Ce systeme de suspension a fini d'etre au point dans le debut des annes 2000 (en 2004 exactement). le principe est celui d'un electro-aimant. Plus que tu veux qui suporte un poids, plus que tu dois envoyer du courant. Le systeme est base sur du haut voltage. En fait le gros probleme de ce projet est le poids et les couts. le projets aurait coute pres de 100 millions de $.

Unlike spring-and-shock absorber systems, Bose's suspension uses high-voltage electrical coils and magnets to counter bumps in the road and prevent roll around corners.



Will people pay for it?
The approach is drawing praise as a revolutionary way to ensure a smooth ride, but doubts center on its cost as rivals push their own suspension improvements that are less radical, but more affordable. Bose's system could add $5,000 or so to a car's cost, along with a few hundred pounds.
"Technically, on paper, I think it's brilliant," said Aly Badawy, a vice president at Livonia, Mich.-based auto parts maker TRW Automotive Holdings Corp., which is developing its own high-end suspension system expected to be ready years before Bose's. "The problem is, is it going to be affordable?"
Bose says his suspension's technical advantages will win over high-end car buyers.
"If you ride over those roll bumps," he said, pointing to obstacles set up for the demonstration, "after just 50 feet you know you've been in a vehicle that has comfort like nothing else."
By year's end, Bose hopes to select a single automaker from a handful of companies interested in making the suspension commercially available in five to six years. He wouldn't identify the companies.
