  • Electrical power assisted steering systems
    Patent number: 6729434
    Abstract: An electric power assisted steering system is disclosed in which a torque demand signal (8) is generated and applied to an electric motor (1) operatively connected to a steering mechanism (5) in order to assist a driver of the vehicle when steering the vehicle. The torque demand signal (8) includes a damping component that is dependent upon a measurement of torque T carried by the steering mechanism and a measurement of the angular velocity &ohgr; of the steering mechanism. The torque produced by the motor (1) is not obtrusive during “hands-on” maneuvers but provides enhanced damping in other maneuvers such as a steering flick.
    Type: Grant
    Filed: June 29, 2001
    Date of Patent: May 4, 2004
    Assignee: TRW LucasVarity Electric Steering Ltd.
    Inventors: Simon David Stevens, Anthony Walter Burton, Andrew James Stephen Williams, John Nicholas Cheel, Russell Wilson Jones
