Title:
車両用オーディオ装置における設定音量調節装置及び調節方法
Document Type and Number:
Japanese Patent JP4116980
Kind Code:
B2
Abstract:
A set volume control device for an on-vehicle audio system includes: a volume control switch (3) to which a vehicle occupant can arbitrarily give an operational input; and a controller for controlling a set volume changer based on a vehicle speed detected by a vehicle speed detector (Sv) and the operational input to the volume control switch(3) so that a set volume of an audio system becomes a low vehicle speed region set volume fixed independently of vehicle speed change in a low vehicle speed region; becomes a high vehicle speed region set volume fixed independently of the vehicle speed change in a high vehicle speed region; and changes according to the vehicle speed change along a predetermined medium vehicle speed region set volume change line connecting the low vehicle speed region set volume and the high vehicle speed region set volume in a medium vehicle speed region between the low vehicle speed region and the high vehicle speed region. The controller changes a setting of the low vehicle speed region set volume according to an operational input to the volume control switch (3) within a first volume setting range set up in advance when the volume control switch (3) is operated in the low vehicle speed region, and changes a setting of the high vehicle speed region set volume according to an operational input to the volume control switch (3) within a millisecond volume setting range set up in advance when the volume control switch (3) is operated in the high vehicle speed region. A lower limit of the millisecond volume setting range is set higher than an upper limit of the first volume setting range. Thus, it is possible to accurately control the volume of the audio system and improve feeling of volume change.
