Abstract: A method and apparatus for determining a center position of the vehicular steering system includes a steering sensor and a control unit. A dynamic center find routine and a long term center find routine are run simultaneously and the results compared to assure accurate dynamic center position for controlling automotive devices.

Abstract: An apparatus and method for determining the centripetal force of an automotive vehicle operating on a roadway includes a vehicle speed measuring mechanism and a steering force measuring mechanism. Information regarding vehicle speed and steering force are fed into a processor which determines the centripetal force of the vehicle.

Abstract: A circuit for correcting a fault in an automotive system having at least two operating states includes an actuator mechanism for placing the system into one of at least two operating states and a switching mechanism, such as a relay, operatively connected with the actuator mechanism for driving the actuator mechanism upon passing a current through the switching mechanism. The circuit further includes a fault warning mechanism for detecting an inability of the actuator to place the system into a desired operating state and for generating a fault warning signal in response to the detection as well as a control unit for activating the switching mechanism according to a predetermined sequence upon generation of the fault warning signal to correct the inability of the actuator mechanism to place the system into a desired operating state.

Abstract: A method and apparatus for determining a center position of the vehicular steering system includes a steering sensor and a control unit. A variable threshold time strategy is employed with a fixed window of operation and a movable window of operation to determine a precise center for the steering system. As an option, the control algorithm may employ both a variable theshold time and a variable size for the movable window of operation.
