Anti-rollover system to be offered on Ford SUVs

Dearborn, Michigan – Ford’s “Roll Stability Control” (RSC), a rollover prevention system that controls a vehicle’s roll motion during extreme maneuvers, is now available for the 2004 Lincoln Aviator and Lincoln Navigator, the company announced. It first debuted on the 2003 Volvo XC90. RSC also will be available on the Ford Explorer, Ford Expedition, and Mercury Mountaineer in the 2005 model year.

Ford’s RSC technology is an active stability enhancement system that builds upon existing yaw stability control systems in the market today. The RSC system continuously calculates if the vehicle may be approaching a situation where rollover is probable and takes action to help prevent rollover.

In Ford’s RSC system, a gyroscopic sensor is included that determines the vehicle’s body roll angle and roll rate. Along with Ford developed algorithms embedded in advanced software, this information is used with other vehicle sensors’ inertial information including yaw rate, lateral and longitudinal accelerations to monitor the vehicle’s roll stability condition approximately 150 times per second. If the vehicle approaches an unstable situation, the vehicle’s RSC system is activated: engine power is reduced and/or the brakes are applied to one or more of the wheels as necessary to help regain vehicle stability.

Ford has a significant number of issued and pending patents on the RSC technology. Because of the immediate safety benefits RSC provides, Ford is already making it available to other companies and automakers via licenses.
