A method and apparatus for classifying a steering behavior of a driver of a vehicle into one of a plurality of behavior control classes for a fatigue detection

摘要

The invention relates to a method and a device (100) for classifying a steering behavior of a driver of a vehicle into one of a plurality of steering behavior classes (105) in order to detect driver fatigue. The method comprises at least one step of reading at least one steering parameter, a step of classifying the driver into one of the steering behavior classes, and a step of determining a fatigue parameter. In the step of reading the at least one steering parameter (125) of the driver is read. The at least one steering parameter (125) represents a steering speed (315) and / or a steering angle, in particular a reaction amplitude and / or a steering speed (315) of the driver. In the classifying step, the driver is classified into one of the steering performance classes (105) using the at least one steering parameter (125) and a predetermined comparison rule (135) to provide the driver's steering behavior class (140). In the step of determining, the fatigue parameter representing a tiredness degree of the driver is determined. The fatigue parameter is determined using the driver's steering behavior class (140) and a number and / or length of deadband events, so-called deadband events. A dead zone event represents an inactive phase in the driver's steering behavior with an immediate subsequent steering action.
