    • A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits a starting movement notification sound to outside of a vehicle to inform a person in an outside area surrounding the vehicle that the vehicle will transition from a stopped state to a moving state, and emits a moving notification sound to outside of the vehicle to inform a person in the outside area surrounding the vehicle that the vehicle is moving. The notification sound control device operates the sound emitting device to selectively emit the starting movement notification sound. The notification sound control device includes a notification sound emission timing section that sets a start timing of the starting movement notification sound in response to a shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed.
    • 车辆通知声发射装置基本上设置有发声装置和通知声音控制装置。 声音发射装置向车辆外部发出开始移动通知声音,以通知车辆周围的外部区域的车辆将从停止状态转移到移动状态,并且向外部发出移动通知声音 车辆通知车辆周围的外部区域的车辆正在移动。 通知声音控制装置操作声音发射装置以选择性地发出开始移动通知声音。 通知声音控制装置包括通知声发射定时部,其响应于已经执行的换档操作和执行了车辆的附加的开始动作准备操作,来设定起动运动通知声的开始定时。

    • A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits forward and reverse advancement notification sounds outside of a vehicle to inform a person in an area surrounding the vehicle that the vehicle will move. The notification sound control device operates the sound emitting device to selectively emit the forward and reverse movement notifications. The notification sound control device includes forward and reverse advancement notification sound emission timing sections. A start timing of the forward advancement notification sound is set in response to both a forward movement shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed. A start timing of the reverse movement notification sound is set to be emitted immediately in response to the reverse movement shift operation having been performed.
    • 车辆通知声发射装置基本上设置有发声装置和通知声音控制装置。 声音发射装置在车辆外部发出向前和向后推进通知声音,以通知车辆周围的区域车辆将移动。 通知声音控制装置操作声音发射装置以选择性地发射正向和反向移动通知。 通知声音控制装置包括前进和后退提前通知声音发射定时部分。 响应于已经执行的前进移动换档操作和已经执行的车辆的附加开始动作准备操作两者来设定前进提前通知声音的开始定时。 响应于已经执行的反向移动移动操作,立即将反向移动通知声的开始定时立即发出。
