Abstract

A method for ascertaining a critical driver behavior, in which an operative control undertaken by the driver is evaluated and compared to a stored user profile in such a way that, given a deviation of the operative control from the stored user profile, a critical driver behavior is ascertained.

Claims

1-8. -8. (canceled)

9. A method for ascertaining a critical driver behavior, comprising:

evaluating an operative-control behavior of a driver;

comparing the operator-control behavior to a stored user profile; and

ascertaining a critical driver behavior if the operative-control behavior deviates from the stored user profile.

10. The method as recited in claim 9, wherein the evaluating step includes evaluating, for determining the operative-control behavior, at least one of an operative-control frequency, an operative-control selection, and an operative-control dynamics.

11. The method as recited in claim 9, wherein repeated deviations from the user profile are evaluated for correction of the user profile.

12. The method as recited in claim 9, wherein a critical driver behavior is relayed to at least one warning system in the vehicle for lowering warning thresholds.

13. The method as recited in claim 9, wherein the operative control includes at least one of a radio operative control, an air conditioner control, a window control, and a seat control.

14. A device for ascertaining a critical driver, behavior, comprising:

a central data acquisition unit configured to acquire a plurality of operator actions;

a memory to store a user profile;

a processing unit configured to compare the operator actions to the user profile; and

an interface configured to output a critical driver behavior to vehicle systems.

15. The device as recited in claim 14, wherein forces acting on operating elements during the plurality of operator actions are communicated to the central data acquisition unit.

16. An operating unit for connection to a central data acquisition unit for recording a plurality of operator actions, comprising:

a device for measuring a force exerted on an operating element during an operator action, the device configured to transmit the measure of the force to the data acquisition unit which determines a critical driver behavior as a function of the measured force and a stored user profile.
