Driving support apparatus, driving support method, and computer-readable recording medium storing driving support program

A driving support method configured to cause a computer to execute a process, the process comprising:

• judging a type of line-of-sight data indicating a direction of the line of sight of a driver;
• estimating an attentive watching state of the driver on a target area to be attentively watched, based on the following:
• the target area to be attentively watched being set depending on a driving situation based on vehicle state information indicating a vehicle state and surrounding state information indicating a state surrounding the vehicle, and
• a direction of the line of sight indicated by a plurality of pieces of line-of-sight data acquired in a judgment time determined depending on the driving situation;
• and
• calculating a confidence level of an estimation result of the attentive watching state based on at least one of the following:
• setting accuracy of the target area to be attentively watched, and
• a configuration state of line-of-sight data associated with each type of the plurality of pieces of line-of-sight data acquired in the judgment time.

A non-transitory computer-readable recording medium storing a driving support program that, when executed, causes a computer to perform a process, the process comprising:

• judging a type of line-of-sight data indicating a direction of the line of sight of a driver;
