Active Steering

	Active Steering Active steering describes a steering system for a vehicle in which the relationship between the driver’s steer inputs and the angle of the steered road wheels may be continuously and intelligently altered. Whilst active steering systems may be found in agricultural equipment and heavy plant, this article concentrates on the application of active steering in BMW passenger cars. ''Active steering'' describes a type of power electric variable gear ratio power steering technology introduced by BMW in 2003 first appearing on the redesigned 5 Series which varies the degree that the wheels turn in response to the steering wheel. At lower speeds, this technology reduces the amount that the steering wheel must be turned – improving performance in situations such as parking and other urban area traffic maneuvers. At higher speeds, the performance is such that increased responsiveness from speed is avoided, improving directional stability. Overview The BMW active steering system util ...

picture info	Power Steering A power steering is a mechanical device equipped on a motor vehicle that helps drivers steer the vehicle by reducing steering effort needed to turn the steering wheel, making it easier for the vehicle to turn or maneuver at lower speeds. Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and reduce considerably the physical effort necessary to turn the wheels when a vehicle is stopped or moving slowly. Power steering can also be engineered to provide some artificial feedback of forces acting on the steered wheels. Hydraulic power steering systems for cars augment steering effort via an actuator, a hydraulic cylinder that is part of a servo system. These systems have a direct mechanical connection between the steering wheel and the linkage that steers the wheels. This means that power-steering system failure (to augment effort) still permits the vehicle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Directional Stability Directional stability is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium (water, air, road surface, etc.) when disturbed (rotated) away from that original direction. If a vehicle is directionally stable, a restoring moment is produced which is in a direction ''opposite'' to the rotational disturbance. This "pushes" the vehicle (in rotation) so as to return it to the original orientation, thus tending to keep the vehicle oriented in the original direction. Directional stability is frequently called "weather vaning" because a directionally stable vehicle free to rotate about its center of mass is similar to a weather vane rotating about its (vertical) pivot. With the exception of spacecraft, vehicles generally have a recognisable front and rear and are designed so that the front points ...

picture info	ZF Friedrichshafen ZF Friedrichshafen AG, also known as ZF Group, originally ''Zahnradfabrik Friedrichshafen'', and commonly abbreviated to ZF (ZF = "Zahnradfabrik" = "Cogwheel Factory"), is a German car parts maker headquartered in Friedrichshafen, in the south-west German state of Baden-Württemberg. Specialising in engineering, it is primarily known for its design, research and development, and manufacturing activities in the automotive industry. It is a worldwide supplier of driveline and chassis technology for cars and commercial vehicles, along with specialist plant equipment such as construction equipment. It is also involved in rail, marine, defense and aviation industries, as well as general industrial applications. ZF has 241 production locations in 41 countries with approximately 148,000 (2019) employees. ZF Friedrichshafen is more than 90% owned by the Zeppelin Foundation, which is largely controlled by the town of Friedrichshafen. History The company was founded in 1915 in Friedri ...
