1. A method for determining a steering wheel angle of an automotive steering mechanism and controlling an automotive device, comprising the steps of:

  • counting steering position data from a steering angle sensor and generating a first signal therefrom representing rotational motion of the steering mechanism;

    measuring a yaw rate from a yaw rate sensor and producing a second signal therefrom representing a steering wheel angle computed from said yaw rate;

    determining a center position estimate from said first signal and said second signal and generating a center position signal therefrom;

    estimating an actual steering wheel angle from said first signal and said center position signal and generating an estimated steering wheel angle signal therefrom; and

    controlling the automotive device using said estimated steering wheel angle signal.
