Warning System for a Motor Vehicle
First Claim
1. A warning system for a motor vehicle, comprising:
- sensor devices for detecting a driving situation;
a warning device for output of a warning to a driver of the motor vehicle;
a device for detecting a driver'"'"'s state of attention, said driver'"'"'s state of attention detecting device comprising operating elements of normally existing vehicle components;
a control device for triggering the warning device as a function of data from the sensor devices and the driver'"'"'s state of attention detecting device; and
wherein the driver'"'"'s state of attention detecting device is operatively configured to infer a degree of a driver'"'"'s reduced attention when a total duration of a sequence of several operating actions with respect to the operating elements of the normally existing vehicle components exceeds a minimum time duration.

Abstract
A warning system for a motor vehicle includes sensor devices for detecting a driving situation, a warning device for the output of a warning to a driver of the motor vehicle, a device for detecting the driver'"'"'s state of attention that includes operating elements of existing vehicle components, and a control device which triggers the warning device as a function of data of the sensor devices and the device for detecting the state of attention. In this warning system, the device for detecting the state of attention infers a reduced degree of driver attention when a total duration of a sequence of several operating actions related to the operating elements exceeds a minimum duration. A conclusion can also be drawn that the degree of driver attention is reduced when operating inputs are triggered that are known a priori as being cognitively demanding, for example, operating a telephone keypad.

17. A method of operating a warning system in a motor vehicle, the warning system including a driver'"'"'s state of attention detection device that includes operating elements of existing vehicle components, the method comprising the acts of:
-
monitoring a total duration of a sequence of several operating actions with respect to the operating elements of the existing vehicle components; determining whether the total duration exceeds a minimum duration; and inferring a reduced degree of driver attention when the total duration exceeds the minimum duration. - View Dependent Claims (18, 19, 20)
