  • Patent number: 8170751
    Abstract: A method for controlling an assisted steering maneuver in an electric power steering (EPS) system includes modeling steering dynamics during a torque overlay operation to generate a dynamic steering model (DSM), measuring vehicle operating values, and detecting a driver intervention in the torque overlay operation based on the DSM and the vehicle operating values. The torque overlay operation is overridden when driver intervention is detected, allowing the driver to regain control of the steering maneuver. A vehicle includes a steering wheel, a steering assist mechanism, and an EPS system having an electronic control unit (ECU) adapted to determine a present intent of a driver of the vehicle to interrupt application of the TOC based on a vehicle operating value transmitted by the driver to the steering wheel. The ECU is operable for interrupting the torque overlay operation when the present intent of the driver is determined.
