Method for assisting driver of motor vehicle given loss of alertness

Abstract

A method for assisting the driver of a motor vehicle is provided. The method includes prescribing a desired driver behavior parameter that describes a desired driver behavior, determining an actual driver behavior parameter that describes an actual driver behavior, and determining a deviation parameter that describes a deviation between the desired driver behavior parameter and the actual driver behavior parameter. The method also includes prescribing a first threshold value for the deviation parameter, raising an error counter if the deviation parameter exceeds the first threshold value, and lowering the error counter if the deviation parameter falls below the first threshold value. The method includes determining an evaluation parameter that describes a change in the error counter over time, prescribing a lower threshold value for the evaluation parameter, and initiating a reaction that affects the behavior of the motor vehicle and/or driver if the evaluation parameter exceeds the lower threshold value.
