Abstract: The travel situation of a vehicle is detected by sensors and a sensor section 110 recognizes the moving state of the vehicle and outputs event signals. A processing section 180 has a sound emission control section that acquires a MIDI message to be used for notifying the travel situation by means of a MIDI sound source generating section. At the same time, it recognizes the priority level of the event signal to be used for notification in terms of urgency or significance and defines the parameter value of the MIDI message so as to bring the localized sound image of the sound to be emitted from a speaker located substantially at the center relative to a driver according to the priority level. Then, it has a sound emitting section 150 emit the sound.

Abstract: A dummy sound generating apparatus includes a dummy sound information storage unit that stores one or more dummy sounds, and an outer generating unit that generates one of the one or more dummy sounds outside of the vehicle upon reception of a dummy sound generation instruction signal. The dummy sound generating apparatus also includes a generation place information storage unit that stores information on a place where a dummy sound is to be generated a current position information acquiring unit that acquires information on a current position of the vehicle, and a control unit that outputs a dummy sound generation instruction signal to the outer generating unit when the current position acquired by the current position information acquiring unit matches with information on a place stored in the generation place information storage unit.

Abstract: A dummy sound information storage unit stores information on a dummy sound, an outer generating unit generates a dummy sound outside the vehicle based upon information stored in the dummy sound information storage unit, a detecting unit detects a predetermined situation while the vehicle is running, and a control unit controls an output of a dummy sound generation instruction signal to the outer generating unit based upon the result detected by the detecting unit.
