1. A vehicle approach notification sound generating apparatus comprising:

  • a vehicle approach notifying unit that outputs a vehicle approach notification sound for notifying pedestrians of approach of an own vehicle;

    a vehicle approach notification sound acquiring unit that acquires a vehicle approach notification sound output from another vehicle;

    a similarity distance calculating unit that calculates a similarity distance which is a metric of similarity between said vehicle approach notification sound of the own vehicle output from said vehicle approach notifying unit and said vehicle approach notification sound of said another vehicle acquired by said vehicle approach notification sound acquiring unit;

    a communication unit configured for communicating with said another vehicle to determine which of said vehicle approach notification sound of said another vehicle and said own vehicle is to be changed; and

    a controller that, when said similarity distance is a predetermined threshold or less, attempts to communicate with said another vehicle via said communication unit and, based on the attempted communication, determines whether said vehicle approach notification sound of said another vehicle or said own vehicle is to be changed, and when said vehicle approach notification sound of said own vehicle is to be changed, makes control to change said vehicle approach notification sound of said own vehicle so that said similarity distance calculated by said similarity distance calculating unit is more than the predetermined threshold.
