Abstract
Technologies and techniques for combating drowsiness of a driver of a motor vehicle. A calculation rule is used in which a fatigue progression curve, that represents a fatigue development of the driver over time, can be generated based on a parameter set, and specific values for the parameter set are determined for a route ahead. The fatigue progression curve for the route ahead may be determined via the calculation rule using the determined values for the parameter set, and the fatigue progression curve is analyzed. A countermeasure may be initiated depending on a result of the analysis, in which countermeasure at least one value of a variable parameter of the parameter set is specifically changed.
Claims19
A method for combating drowsiness of a driver of a motor vehicle, comprising:
- determining a fatigue class representing a fatigue level of the driver, wherein the fatigue class is determined based on at least one evaluation criterion;
- selecting at least one countermeasure for the determined fatigue class using an assignment rule in which different fatigue classes are assigned respective countermeasures;
- and
- triggering the at least one selected countermeasure.
A method for combating drowsiness of a driver of a motor vehicle, comprising:
- processing a calculation rule based on a parameter set to generate a fatigue progression curve representing a fatigue development of the driver over time;
- determining values for the parameter set for a driving route;
- determining a predicted fatigue progression curve for the driving route based on the calculation rule using the determined values for the parameter set;
- processing the predicted fatigue progression curve;
- and
- initiating a countermeasure based on the processed predicted fatigue progression curve, wherein the countermeasure comprises changing at least one value of a variable parameter of the parameter set.
An apparatus for combating drowsiness of a driver of a motor vehicle, comprising:
- one or more sensors;
- and
- an electronic computing device, operatively coupled to the one or more sensors, the electronic computing device being configured to:
- process a calculation rule based on a parameter set to generate a fatigue progression curve representing a fatigue development of the driver over time;
