Abstract (en)
[origin: EP0147539A2] In a drowsy driving detection system, drowsiness is recognized when an extended period without any steering adlustments is followed by abrupt steering corrections, of at least minimal speed and extent, in both directions. The minimal speed values are selected in accordance with the detected angular extent of each steering correction. The extent of each steering correction may be subdivided into a number of ranges, each associated with a predetermined reference minimal steering speed value. The reference speed value selection process may be applied to the steering corrections in either or both directions.
