PROBLEM TO BE SOLVED: To balance between an advantage of quietness during motor-driven travel and addition of a pseudo engine sound.MEANS FOR SOLVING THE PROBLEM: A pseudo engine sound is generated upon detection of a person, detection of being outside an express highway by an ETC, detection of a narrow road through car navigation, and detection of a cross walk through a signal wave. During an environment silent time and a midnight time zone, the pseudo engine sound is not generated. A volume of the pseudo engine sound is adjusted according to a magnitude of environment sound, time zone, image recognition in a drive recorder and weather and the like. The pseudo engine sound is generated mildly for preventing a pedestrian from being amazed. A volume balance between the front and back sides and the right and left sides of the vehicle is changed during back and winker operation time. The pseudo engine sound is pulsed during a brake or acceleration operation. In place of the pseudo engine sound, an ultrasonic for seeing-eye dog is output. Generation of the pseudo engine sound is displayed in the vehicle. For sampling of the engine sound, the vehicle is forced to travel at low speed on an engine. A pseudo engine sound-off travel is recorded by the drive recorder. A travel without the pseudo engine sound is inhibited when a person is detected or in the vicinity of a cross walk.SELECTED DRAWING: Figure 1
【課題】モータ走行における静粛性の利点と擬似エンジン音付加の調和をとる。【課題を解決するための手段】人検知、ETCによる高速道路外検知、カーナビによる狭道検知や信号電波による横断歩道検知等で擬似エンジン音を発生させる。環境静寂時や深夜時間帯、擬似エンジン音を発生させない。環境音の大小、時間帯、ドライブレコーダの画像認識、天候等に応じ擬似エンジン音量を調節する。擬似エンジン音をソフト発生させ歩行者を驚かせない。バック時やウインカ操作時、車両の前後左右の音量バランスを変える。ブレーキやアクセル操作で擬似エンジン音を脈動させる。擬似エンジン音に代え盲導犬用超音波を出す。擬似エンジン音発生を車内表示する。エンジン音サンプリングのため、低速強制エンジン走行させる。擬似エンジン音オフ走行をドライブレコーダに記録する。人検知時や横断歩道近辺での擬似エンジン音なし走行を禁止する。【選択図】図1
