Method and device for warning a driver
First Claim
Patent Images
1. A method for adaptively warning a driver, comprising:
- implementing a warning by at least one of an acoustic, an optical and a haptic indicator;
deriving a variable that represents a degree of a driver'"'"'s inattentiveness at a selected point in time, from at least one operating variable; and
generating an initial warning signal that is adapted to the degree of the driver'"'"'s inattentiveness at the selected point in time, wherein a magnitude of the initial warning signal is varied depending upon the variable that represents the degree of the driver'"'"'s inattentiveness at the selected point in time.

-
implementing a warning by at least one of an acoustic, an optical and a haptic indicator;
deriving a variable that represents a degree of a driver'"'"'s inattentiveness, from at least one operating variable; and
generating a warning signal, wherein a magnitude of the warning signal is varied depending upon the variable that represents the degree of the driver'"'"'s inattentiveness, and wherein the magnitude of the warning signal is independent of a duration of driver inattentiveness.

10. A device for adaptively warning a driver, comprising:
a control unit for receiving at least one operating variable, deriving a variable that represents a degree of a driver'"'"'s inattentiveness at a selected point in time, based on the at least one operating variable, and outputting an initial warning signal that is adapted to the degree of the driver'"'"'s inattentiveness at the selected point in time, the control unit including means for generating the warning signal, the control unit further including means for specifying a magnitude of the warning signal that varies depending upon the variable that represents the degree of a driver'"'"'s inattentiveness at the selected point in time.
