Method for furnishing a warning signal, and method for generating a pre-microsleep pattern for detection of an impending microsleep event for a vehicle

A microsleep early detection apparatus for warning of an impending microsleep event for a vehicle, the microsleep early detection apparatus comprising:

• an interface to a behavior sensor unit;
• processing circuitry;
• and
• an output device;
• wherein the processing circuitry is configured to:
• obtain, based on information obtained via the interface, at least one pattern of a behavior of a driver while driving the vehicle;
• compare the obtained pattern to at least one stored pre-microsleep pattern that represents an individual behavior of the driver that occurs prior to a microsleep event;
• and
• output, via the output device, a warning signal responsive to determining, based on a result of the comparison, that a predetermined relationship exists between the obtained pattern and the pre-microsleep pattern.

A generating apparatus for generating a pre-microsleep pattern for detection of an imminent microsleep event for a vehicle, the generating apparatus comprising:

• an interface;
• processing circuitry;
• and
• a data storage;
• wherein the processing circuitry is configured to:
• read in, via the interface, the pre-microsleep pattern, the pre-microsleep pattern representing an individual behavior of a driver that occurs prior to a microsleep event;
• and
• store the read in pattern in the data storage.

A non-transitory computer-readable medium on which are stored instructions that are executable by a computer processor and that, when executed by the processor, cause the processor to perform a method for warning of an imminent microsleep event, the method comprising:

• obtaining at least one pattern of a driver while driving a vehicle;
• comparing the obtained pattern to at least one stored pre-microsleep pattern that represents an individual behavior of the driver that occurs prior to a microsleep event;
• and
• outputting a warning signal responsive to determining, based on a result of the comparison, that a predetermined relationship exists between the obtained pattern and the pre-microsleep pattern.
