Aggressive driver, defensive driver, middle-of-the-road driver; all drivers have a unique set of habits and behaviors behind the wheel that determine their individual style of driving. DaimlerChrysler researchers in Germany have developed computer software that constantly monitors and analyzes a driver's maneuvers, such as acceleration, braking and steering, then classifies the driver by style. The computer program goes even further: it adapts the engine and transmission within a fraction of a second to accommodate the individual's driving style. The computer software also recognizes changes in driving conditions, such as a move from expressway to city street driving. The result is a more comfortable ride, better fuel economy and a longer service life for the automobile.
