Active Stabilizer Suspension System

rdf:langString Active Stabilizer Suspension System

rdf:langString Active Power Stabilizer Suspension System (APSSS), is an electric active suspension system with active anti-roll bars developed by Toyota Motor Corporation for its high-end vehicles including Lexus models. By altering stabilizer bar stiffness, this system acts to reduce body tilt during cornering, keeping the vehicle more level during turns and improving handling, as opposed to the natural tendency of a vehicle to roll due to the lateral forces experienced during high-speed maneuvering. The active stabilizer system relies on vehicle body sensors and electric motors. The first production usage of this system was introduced in August 2005 with the Lexus GS430 sport sedan, followed by the 2008 Lexus LS 600h luxury sedan. The development of APSSS is claimed to be the world's first electric active stabilizer system. It is a system improvement of an earlier Toyota technology called Toyota TEMS (Toyota Electronic Modulated Suspension).
