1. A warning system, comprising:

  • an angle-detector that indicates a steering-angle of a hand-wheel of a host-vehicle;

    a curvature-detection-means that detects a curvature of a portion of a roadway traveled by the host-vehicle, said portion characterized as ahead of the host-vehicle in a current direction of travel;

    an alert-device; and

    a controller-circuit in communication with the angle-detector, the curvature-detection-means, and the alert-device, the controller-circuit configured to;

    determine an average-steering-angle in accordance with the steering-angle indicated by the angle-detector;

    determine an expected-steering-angle based on the curvature detected by the curvature-detection-means;

    determine a steering-angle-deviation based on the average-steering-angle and the expected-steering-angle;

    determine whether the steering-angle-deviation is greater than a predetermined deviation-threshold;

    in accordance with the determination that the steering-angle-deviation is greater than the deviation-threshold determine a frequency of the steering-angle-deviation; and

    activate the alert-device when the frequency of the steering-angle-deviation exceeds a change-threshold.
