ADVANCETRAC® WITH ROLL STABILITY CONTROL™ – THE FORD ADVANTAGE
2005 Shanghai Motor ShowAdvanceTrac® with Roll Stability Control ™ (RSC) is standard equipment on the 2005 Lincoln Navigator that is on display at this year's Shanghai auto show.
Ford is the first automaker to develop AdvanceTrac® with RSC™ technology – an active stability enhancement system that significantly builds upon existing stability control systems on the market today. While typical electronic stability control systems are designed to control yaw or spin-out only, Ford’s AdvanceTrac® with RSC™ goes one important step further.
AdvanceTrac® with RSC™ adds a second gyroscopic roll sensor to determine the vehicle’s body roll angle and roll rate. If this unique roll rate sensor detects that the vehicle is about to roll, the system automatically applies additional countermeasures – such as reducing engine power 15 percent and/or applying brakes to one or more wheels – to enhance vehicle rollover resistance.
AdvanceTrac® with RSC™ – Four Systems in One
AdvanceTrac® with RSC™ is an integrated system of four major components – one more than typical electronic stability control systems. Ford’s exclusive vehicle roll motion sensor sets AdvanceTrac® with RSC™ apart from other automakers’ stability control systems and takes additional steps to enhance vehicle rollover resistance. The system includes:
Anti-lock Brake System (ABS)
Anti-lock Brake System (ABS) – this feature regulates brake pressure to help prevent wheel lock-up when trying to stop the vehicle.
Traction Control
When the system detects a loss of traction, this quickly responds by reducing engine power when necessary and selectively applying brake force to the slipping wheel while transferring power to the opposite wheel. It helps give drivers a more seamless and controlled driving experience.
Yaw Control
This component helps drivers avoid skidding and fishtailing. When understeer (which leads to skidding) or oversteer (which leads to fishtailing) is detected, the system selectively applies individual brakes and modifies engine power to maximize control.
Vehicle Roll Motion Sensor (a Ford exclusive)
Ford-exclusive AdvanceTrac® with RSC™ utilizes a gyroscopic sensor to help monitor vehicle roll motion approximately 150 times per second. If it detects the possibility of a rollover, the system automatically engages AdvanceTrac® with RSC™ to help keep all four wheels safely on the ground. This feature is especially beneficial when a vehicle is fully loaded.
Stability Control Plus Choice
On/Off Switch – For added security: AdvanceTrac® with RSC™ is automatically engaged each time the vehicle is started. However, a center-console button allows drivers to turn the system off on the rare occasion, such as during low-speed off-roading, or in deep snow or mud, when they may want the wheels to spin freely to help the tires "dig" for traction.
An Extra Measure of Control
The Ford AdvanceTrac® with RSC™ system adds another dimension of advanced technologies and software to monitor and control a vehicle’s roll motion during extreme maneuvers. AdvanceTrac® with RSC™ continuously calculates if the vehicle may be approaching a situation where rollover is probable and takes additional action to help enhance rollover resistance.
