- the in-vehicle device receives the response signal and performs authentication based on whether or not the ID code registered in advance matches the ID code included in the response signal.
- the electronic key since the electronic key transmits and receives signals to and from the in-vehicle device, the remaining amount of the storage battery built in the electronic key gradually decreases. For this reason, when the remaining amount of the storage battery falls below a predetermined level, it becomes impossible to lock and unlock the door of the vehicle using the electronic key, start the engine, or the like.
- the transmission interval of the response request signal transmitted by the electronic key during wireless communication with the in-vehicle device is set in advance.
- the transmission interval is longer than the set transmission interval.

Abstract
Description
上記課題を解決するため本発明に従う電子キー端末の電力消費抑制装置は、車両に搭載された車載装置との通信を行う電子キー端末の電力消費を抑制する電子キー端末の電力消費抑制装置であって、前記電子キー端末が備える蓄電池を充電可能な地点である充電ポイントを特定する充電ポイント特定部と、前記特定された充電ポイントが前記車両の到着地及び目的地及び該目的地までの経路のいずれかに含まれないことを条件として前記電子キー端末の電力消費の抑制を行う電力消費抑制部と、を備える。
例えば、車両や電子キー端末のユーザの自宅や勤務先等は、車両の拠点であり、電子キー端末の充電が安定して行われる傾向にある。また、拠点では、電子キー端末の充電が行われる頻度が高い。
図1に示すように、本実施の形態の電子キー端末の電力消費抑制装置及び電子キー端末の電力消費抑制方法が適用される車両100は、該車両100のエンジンの運転開始(スタート)及び運転終了(ストップ)を検知するスタート/ストップ検知部110を備えている。また、車両100は、当該車両100のドアの施錠(ロック)及び解錠(アンロック)を検知するロック/アンロック検知部120を備えている。さらに、車両100は、当該車両100の到着地及び目的地に関する情報を検出する到着地/目的地検出部130を備えている。
また、到着地/目的地検出部130は、車両100の目的地に関する情報を取得する。到着地/目的地検出部130は、例えば、ナビゲーションシステム131に設定された目的地に基づき、車両100の目的地の緯度経度等を示す情報を取得する。到着地/目的地検出部130は、取得した目的地の緯度経度等を示す情報を、通信部101を介して電子キー端末200に送信する。
図2に示すように、ステップS100において、電子キー端末200により、車両100のエンジンがストップされ、ドアがロックされたことが検出されると、車両100が停止し、或る地点に到着したことが検出される。
また、図3に示すように、電子キー端末200が車両100内で利用されるときには、電子キー端末200により、車両100のドアがアンロックされ、エンジンがスタートされたことが検出されると、車両100が走行を開始し、或る目的地に向かっていることが検出される(ステップS200)。
次に、図4を参照して、本実施の形態の電子キー端末の電力消費抑制装置及び電子キー端末の電力消費抑制方法による電力消費の抑制態様を説明する。
また、例えば車両100が自宅に駐車され、車両100を下車したユーザに所持された電子キー端末200が自宅から地点Cに向かうときには、電子キー端末200が地点Cで電子キーとして利用されないことから、蓄電池203の電力消費の抑制が行われない。
(1)電子キー端末200が備える蓄電池203を充電可能な充電ポイントが特定された。そして、特定された充電ポイントが車両100の到着地及び目的地に含まれないことを条件として電子キー端末200の電力消費が抑制された。このため、蓄電池203の充電が困難な状況下では蓄電池203の残量が低下することが抑制される。よって、蓄電池203の残量が低下する以前に電力消費が抑制される。これにより、電子キー端末200の消費電力の的確な抑制が図られる。
・スタート/ストップ検知部110は、電子キー端末200から送信される信号に基づき、エンジンの運転開始(スタート)及び運転停止(ストップ)を検知した。これに限らず、スタート/ストップ検知部110は、例えば、車両100のアクセサリーポジションのオン/オフの切り換えに基づき、エンジンのスタート/ストップを検知してもよい。また、スタート/ストップ検知部110は、例えば、車両100のエンジンを制御する制御装置の制御信号に基づき、エンジンのスタート/ストップを検知してもよい。この他、エンジンのスタート/ストップの検知手法は適宜変更されることが可能である。
・充電ポイントは、目的地及び到着地を含む所定範囲のエリアであってもよい。
