Abstract
A method and a device are provided for detecting when the driver of a motor vehicle becomes inattentive. A steering inactivity phase and a subsequent steering action are detected in this context. A steering inactivity phase is detected if the absolute value of the steering wheel angle, of its change over time, or both, during a predefined time threshold value, does not exceed a first threshold value. A steering action is detected if the absolute value of the steering wheel angle, of its change over time, or both, exceeds a second threshold value. The first threshold value and the second threshold value are modified in a driver-specific fashion.

10. A method for detecting when a driver of a vehicle becomes inattentive, in which inattentiveness is determined as a function of a steering inactivity phase and a subsequent steering action, comprising:
-
detecting a steering inactivity phase when the absolute value of at least one of a steering wheel angle and a change in the steering wheel angle over time during the period of a predefined time threshold value does not exceed a first threshold value that is modifiable in a driver-specific fashion, and detecting a steering action when the absolute value of at least one of the steering wheel angle and a change in the steering wheel angle over time exceeds a second threshold value that is modifiable in a driver-specific fashion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
