DISTANCE MEASURING SYSTEM
To provide a distance measuring system that can ensure the communication performance of indoor ranging communication regardless of an open or closed state of an opening.SOLUTION: Two vehicle anchors 11 and 12 for transmitting and receiving ranging signals in a UWB band are installed in a passenger compartment. When a door is closed, only the vehicle anchor 11 is used and UWB communication (indoor ranging communication) with a portable device 2 is performed with the one vehicle anchor 11. On the other hand, when the door is open, since an effect of multipath cannot be expected, the vehicle anchor 12 is also used in addition to the vehicle anchor 11, and UWB communication (indoor ranging communication) with the portable device 2 is performed with the plurality of vehicle anchors 11 and 12.SELECTED DRAWING: Figure 2
【課題】開口部の開閉状態にかかわらず室内測距通信の通信性能の確保を可能にした距離測定システムを提供すること。【解決手段】車室内には、ＵＷＢ帯の測距信号を送受信する２つの車両アンカー１１、１２が設置されている。ドア閉時は、車両アンカー１１のみを使用して、１つの車両アンカー１１で携帯機２とＵＷＢ通信（室内測距通信）を行う。一方、ドア開時は、マルチパスの影響を期待できなくなるので、車両アンカー１１の他、車両アンカー１２も使用して、複数の車両アンカー１１、１２で携帯機２とＵＷＢ通信（室内測距通信）を行う。【選択図】図２
