Active Systems
Some high-priced cars, such as the Range Rover Sport and BMW 7-series, have begun to use "active" anti-roll bars that can be proportionally controlled automatically by a suspension-control computer, reducing body lean in turns while improving rough-road ride quality. The first to use this was the Citroen Xantia Activa, a medium sized sedan sold in Europe. The Activa system featured an anti-roll bar that could be stiffened under the command of the suspension ECU during hard cornering. The car rolled at any time at most 2 degrees. Mercedes S-class ABC system uses another approach: the computer uses sensors to detect lateral load, lateral force, and height difference in the suspension strut, then uses hydraulic pressure to raise or lower the spring to counter roll. This system removes the anti-roll bar. Most active roll control systems allow a small degree of roll to give a more natural feel.

Famous quotes containing the words active and/or systems:
“So hills and valleys into singing break;
And though poor stones have neither speech nor tongue,
While active winds and streams both run and speak,
Yet stones are deep in admiration.
Thus praise and prayer here beneath the Sun
Make lesser mornings when the great are done.”
—Henry Vaughan (1622–1695)
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
