Driver assistance system and driver assistance method for a vehicle

A driver assistance method for a vehicle, comprising:

• recognizing, with a processor of a driver assistance system, a multiplicity of individual glances by a driver away from a reference line of vision;
• determining, with the processor, a glance duration for each individual glance of the multiplicity of individual glances;
• recognizing, with the processor, a change in the glance duration over time and with regard to a threshold value;
• and
• triggering, with the processor, at least one vehicle function on the basis of the recognized change in the glance duration;
• wherein the method further comprises
• changing, with the processor, the threshold value from a first value to a second value, which is different than the first value, when the change in the glance duration is recognized;
• and
• changing, with the processor, the threshold value from the second value back to the first value when a retrograde change in the glance duration is recognized.

A non-transitory computer-readable storage medium, comprising a set of instructions configured to be executed on one or more processors and cause the one or more processors to perform acts of:

• recognizing a multiplicity of individual glances by a driver away from a reference line of vision;
• determining a glance duration for each individual glance of the multiplicity of individual glances;
• recognizing a change in the glance duration over time and with regard to a threshold value;
• and
• triggering at least one vehicle function on the basis of the recognized change in the glance duration;
• wherein the set of instructions further cause the one or more processors to perform acts of:
• changing the threshold value from a first value to a second value, which is different than the first value, when the change in the glance duration is recognized;
• and
• changing the threshold value from the second value back to the first value when a retrograde change in the glance duration is recognized.
