Driving assistance apparatus and program

A non-transitory computer-readable storage medium storing a program enabling a computer to perform:

• a no-passing determining step of determining whether or not a road section corresponding to a current location of an own vehicle corresponds to a no-passing zone;
• a vehicle detecting step of detecting a leading vehicle that is a vehicle ahead of the own vehicle on a course on which the own vehicle is traveling;
• an operation state recognizing step of recognizing an operation state of the lading vehicle detected at the vehicle detecting step;
• a passing detecting step of detecting a passing maneuver performed by the own vehicle to pass the leading vehicle detected at the vehicle detecting step;
• and
• a warning control step of performing a warning operation that is an operation to output a warning to a driver of the own vehicle when the passing maneuver is detected at the passing detecting step under a condition that the road section corresponding to the current location is determined to correspond to the no-passing zone at the no-passing determining step, and prohibiting the warning operation when the operation state of the leading vehicle recognized at the operation state recognizing step meets a predetermined passing-allowed condition that is a condition under which passing is allowed.

A driving assistance method comprising:

• determining, by a driving assistance apparatus mounted to an own vehicle, whether or not a road section corresponding to a current location of the own vehicle corresponds to a no-passing zone;
• detecting, by the driving assistance apparatus, a leading vehicle that is a vehicle ahead of the own vehicle on a course on which the own vehicle is traveling;
• recognizing, by the driving assistance apparatus, an operation state of the detected lading vehicle;
• detecting, by the driving assistance apparatus, a passing maneuver performed by the own vehicle to pass the detected leading vehicle;
• performing, by the driving assistance apparatus, a warning operation that is an operation to output a warning to a driver of the own vehicle when the passing maneuver is detected under a condition that the road section corresponding to the current location is determined to correspond to the no-passing zone;
• and
• prohibiting, by the driving assistance apparatus, the warning operation when the recognized operation state of the leading vehicle meets a predetermined passing-allowed condition that is a condition under which passing is allowed.
