PROBLEM TO BE SOLVED: To suitably perform output control of simulated sound while considering possibility of existence of an object to be informed in surroundings to change in accordance with a road type on which a vehicle travels.SOLUTION: A determination unit 740A acquires road information in a storage unit 710 on the basis of a current position of a vehicle CR detected by a position detecting unit 720 and specifies presence or absence of an opposite traffic lane of a road on which the vehicle CR travels. Then, the determination unit 740A determines a reaching range of simulated sound to be output toward the outside of the vehicle on the basis of the specified result on presence or absence of the opposite traffic lane. Continuously, a control unit 750 controls an output amount of the simulated sound to be output from a speaker of a simulated sound generating unit 760A on the basis of the determined reaching range. Consequently, the simulated sound having the controlled amount is output toward the outside of the vehicle from the speaker of the simulated sound generating unit 760A.SELECTED DRAWING: Figure 1

    【課題】走行中の道路種別に対応して変化する周囲における報知対象の存在の可能性を考慮しつつ、擬似音の出力制御を適切に行う。【解決手段】決定部740Aが、位置検出部720が検出した車両CRの現在位置に基づいて、記憶部710内の道路情報を取得し、車両CRが走行中の道路の対向車線の有無を特定する。そして、決定部740Aが、対向車線の有無の特定結果に基づいて、車外に向けて出力する擬似音の到達範囲を決定する。引き続き、制御部750が、決定された到達範囲に基づいて、擬似音生成部760Aのスピーカから出力する擬似音の出力音量を制御する。この結果、擬似音生成部760Aのスピーカから、当該制御された音量の擬似音が、車外へ向けて出力される。【選択図】 図1
