PORTABLE MACHINE AND ELECTRONIC KEY SYSTEM FOR VEHICLE
To prevent a response signal from being output in response to a signal transmitted from an on-vehicle machine in a situation where a portable machine is not carried by a user.SOLUTION: A mobile machine includes a strength detection unit 121 that detects a received signal strength of a signal from an on-vehicle machine, a storage medium 130, a strength vector storage control unit 122 that newly stores or overwrites and stores a received signal strength of a first signal polled from the on-vehicle machine as a strength vector on the storage medium and newly stores a received signal strength of a second signal transmitted from the on-vehicle machine corresponding to an operation of a door of a vehicle as a strength vector, a movement state estimation unit 123 that estimates whether or not the mobile machine is in a moving state by using the strength vector corresponding to the received signal strength of the second signal and a strength vector stored prior to the strength vector in time, and response signal output units 124, 125 that output a response signal including an identifier of the mobile machine when the mobile machine is estimated to be in the moving state, and do not output the response signal when estimated not to be in the moving state.SELECTED DRAWING: Figure 1
【課題】携帯機がユーザに携帯されていない状況において、車載機から送信される信号に対して応答信号を出力することを抑制する。【解決手段】携帯機は、車載機からの信号の受信信号強度を検知する強度検知部１２１と、記憶媒体１３０と、車載機からポーリングされる第１信号の受信信号強度を強度ベクトルとして記憶媒体に新規記憶又は上書き記憶し、車両のドアの操作に応じて車載機から送信される第２信号の受信信号強度を強度ベクトルとして新規記憶する強度ベクトル記憶制御部１２２と、第２信号の受信信号強度に相当する強度ベクトルと、該強度ベクトルよりも時間的に前に記憶された強度ベクトルとを利用して、携帯機が移動状態であるか否かを推定する移動状態推定部１２３と、移動状態であると推定された場合に携帯機の識別子を含む応答信号を出力し、移動状態でないと推定された場合に応答信号を出力しない応答信号出力部１２４、１２５と、を備える。【選択図】図１
