【発明の属する技術分野】
本発明は、車両盗難防止システムに関するものである。
【0002】
【従来の技術】
従来この種の車両盗難防止システムとして、例えば特許文献1または特許文献2に開示されているものがある。なお、ここでいう車両盗難とは、車両自体の盗難および車両内ある物の盗難の両方を示す。
【0003】
特許文献1に開示されている盗難防止装置は、挿入孔にキー以外の物が挿入された時に沈み込むトップリングと、このトップリングが沈み込んだことを検出するセンサとを有し、キー以外の物が挿入孔に挿入されると前記トップリングが沈み込み、それを前記センサにより検出し警報を発することで車両盗難を防止している。
【0004】
また、特許文献2に開示されている車両監視装置においては、振動センサを用いて車両への侵入者を検知すると共に、さらに磁界センサを用いて侵入者の乗車/降車の手順からその侵入者が正規の所有者かどうかを判断し、正規の所有者ではないと判断すれば、警告ランプやスピーカを用いて警報を発し、車両盗難を防止している。
【0005】

【発明が解決しようとする課題】
しかしながら、上記した特許文献1の発明では、ピッキング以外の手段(例えば、窓ガラスを破壊されたなど。)で車内に侵入されてしまうと警報が作動せず容易に盗難行為をされてしまう恐れがあった。また、この発明を用いるには、車両の改造又は専門者による取り付け作業が必要となり、使用者が簡単に使用することができなかった。
【0008】
また、特許文献2の発明は、車の所有者が手順通りに乗車/降車を行わないと正しく監視モードのセット/解除ができず、車両の所有者にとって面倒なものとなっていた。

【0016】
請求項6記載の車両盗難防止システムは、請求項5記載の発明において、前記振動センサの感度を切り替える感度切替部を前記無線送信器に設けたものとした。
【0017】
【発明の実施の形態】
以下、本発明を実施形態1から実施形態3によって説明する。
【0018】
(実施形態1)
図1に、本実施形態の車両盗難防止システムの構成をブロック図で示す。この車両盗難防止システムは、車内に設置され車内への侵入者を検知すると無線で外部に検知信号s1を出力する無線送信器Aと、車の所有者の自宅に設置され、無線送信器Aからの検知信号を受信すると外部に警報を出力し家人に車両盗難を知らせる無線受信器Bとからなる。
【0019】
無線送信器Aは、車内への侵入者を振動により検知する振動センサ1と、警戒状態と非警戒状態との2つの状態を有し警戒状態の時に振動センサ1の出力から車内へ人が侵入してきたと判断すると無線送信部3から特定小電力無線などを用いて無線で検知信号s1を送信する送信側状態判断部2と、振動センサ1の感度を切り替える感度切替スイッチS4とを備えている。
【0020】
送信側状態判断部2と無線送信部3は、図2に示すように器体Aa内に収容され、振動センサ1はハーネスhを介して器体Aaと接続されている。感度切替スイッチ4は、器体Aaの表面に切替え操作可能に設置され(図示せず)、振動センサ1の感度を例えば3段階(高、中、低)に切り替えることができる。振動センサ1の感度を切り替えることで、送信側状態判断部2が車内へ人が侵入してきたと判断する判断基準を調節することができる。
【0021】
器体Aaの後面側には、図3に示すようにマグネットmが固着されており、マグネットmの磁力により器体Aaを車内のスチール部分に簡単に取り付けることができる。また、器体Aaをマグネットmで取り付けることにより、器体Aaの設置場所の変更も容易である。
【0022】
また、図2に示すように振動センサ1には吸着板1aが取り付けてあり、車内の窓ガラスなどに吸着板1aを介して振動センサ1を貼り付けることができる。振動センサ1を窓ガラスに貼り付けることで、窓ガラスの破壊等による侵入も検知することができる。
【0023】
無線受信器Bは、前記無線送信部3からの信号を受信する無線受信部10と、警戒状態と非警戒状態との2つの状態を有し警戒状態の時に前記無線受信部10が検知信号s1を受信すると異常発生と判断し警報出力部12としてのスピーカと警報ランプから警報を発生させる受信側状態判断部11と、前記受信側状態判断部11の警戒状態を解除するための警戒解除釦13と、警戒解除釦13が操作された時点から所定の時間遅延させて受信側状態判断部11の警戒状態を解除し非警戒状態へと移行させる遅延回路14と、前記受信側状態判断部11を警戒状態に再セットするための警戒セット釦(図示せず。)とを備えている。
【0024】
なお、前記警戒セット釦と警戒解除釦13との代わりに、例えば、1つのレバースイッチの切り替えにより受信側状態判断部11の状態を切替えるようにしてもよい。
【0025】
無線受信器Bは、図示しない器体内に受信側状態判断部11と無線受信部10と遅延回路14とが収納され、前記警戒セット釦と警戒解除釦13とが前記器体の表面に操作可能に設置され、警報出力部12としてのスピーカと警告ランプとが器体の表面から外部に臨んでいる。
【0026】
次に、以上のように構成された本実施形態の車両盗難防止システムの動作について説明する。
【0027】
まず準備として、無線送信器Aの器体Aaをマグネットmにより車内に取り付け、振動センサ1を吸着板1aにより窓ガラスに貼り付けておく。無線送信機Aは、降車の際に図示しない警戒セット釦により警戒状態にセットしておく。無線受信器Bは自宅に設置し、受信側状態判断部11を警戒状態にセットしておく。
【0028】
人が車の窓ガラスを割ったり鍵をこじ開けたりして車内に侵入しようとすると、その時の振動を振動センサ1が検知して、送信側状態判断部2へと信号を出力する。
【0029】
送信側状態判断部2は、振動センサ1の出力から車内へ人が侵入してきたか否かを判断し、侵入者と判断すれば無線送信部3から検知信号s1を出力する。
【0030】
無線受信器Bは、無線送信器Aからの検知信号s1を受信すると受信側状態判断部11が異常発生と判断し、警報出力部12としてのスピーカと警告ランプから警報音と光を発生させて、家人に車内に人が侵入してきたことを報知する。
【0031】
これにより、家人は侵入者に気づき、車両盗難を防止することができる。
【0032】
車の所有者が車で外出する場合は、所有者自身の乗車動作によって警報が誤発報されないように、無線受信器Bの警戒解除釦13を操作して受信側状態判断部11を非警戒状態へと切り替えてから外出する。
【0033】
この時、無線受信器Bでは遅延回路14が働き、前記解除操作から予め設定しておいた所定の時間(例えば、自宅から駐車場へ行くまでの時間。)経過後に受信側状態判断部11が非警戒状態へと移行する。つまり、無線受信器Bの警戒解除釦13を操作しても、操作から所定の時間内は非警戒状態に移行せず、警戒状態が維持される。
【0034】
よって、自宅と駐車場とが離れていて自宅を出てから駐車場に着くまでに時間がかかるような場合でも、所定の時間内は無線受信器Bの警戒状態が維持されるので、万が一自宅から駐車場に着くまでの間に車両盗難が行われようとしても、無線受信器Bから警報が発せられ、家に居る家人が侵入者に気づき、車両盗難を防止することができる。
【0035】
所定の時間経過後は、受信側状態判断部11が非警戒状態へと移行するので、無線送信器Aの警戒状態を解除する前に乗車しても、その乗車動作によって警報が誤発報されることもない。
【0036】
かかる車両盗難防止システムにおいては、無線送信器Aを車内にマグネットmにより取り付け、振動センサ1を吸着板1aにより窓ガラスなどに貼り付けるだけで、簡単に使用することができ、車両の改造や専門者による取り付け作業も必要としない。さらに、遅延回路14を設けたことにより、自宅と駐車場とが離れていて自宅を出てから駐車場に着くまでに時間がかかるような場合でも、自宅で警戒状態を解除してから所定の時間内は無線受信器Bの警戒状態が維持されるので、万が一自宅から駐車場に着くまでの間に車両盗難が行われようとしても車両盗難を防止することができ、盗難防止効果が高い。また、感度切替スイッチ4を設けたことにより、振動センサ1の取り付け場所や車の停車場所などに応じて振動センサ1の感度を切り替えることができ、誤発報を減らすことができる。
【0037】
(実施形態2)
本実施形態における基本構成は実施形態1と共通するために共通する部分については同一の符号を付して説明を省略し、本実施形態の特徴となる部分についてのみ詳細に説明する。
【0038】
則ち本実施形態は、実施形態1に対して、無線送信Aに遅延回路6を設けた点に特徴がある。
【0039】
本実施形態の無線送信器A1の構成を図4のブロック図に示す。無線送信器A1は、振動センサ1と送信側状態判断部2’と無線送信部3と感度切替スイッチ4と警戒セット釦5と遅延回路6と警戒解除釦(図示せず)とを備えている。
【0040】
遅延回路6は、警戒セット釦5が操作された時点から所定の時間(例えば、30秒。)経過後に送信側状態判断部2を非警戒状態から警戒状態へと移行させ警戒状態を開始させる。つまり、警戒セット釦5を操作しても、操作から所定の時間内は警戒状態が開始せず、非警戒状態が維持される。
【0041】
かかる車両盗難防止システムにおいては、車から降りる際に無線送信器A1の警戒セット釦5を操作して無線送信器A1を警戒状態にしても、遅延回路6によりその操作の時点から所定の時間内は非警戒状態が維持され警報が発せられないので、前記所定の時間内に降車すれば、仮に無線受信器Bが警戒状態のままでも、降車の際のドアの開閉などによる振動で警報が誤発報されることがない。
【0042】
なお、図5に示すように、警戒セット釦5と前記警戒解除釦との代わりに、電源スイッチ5’を用いてもよい。すなわち、電源スイッチ5’のオフ状態では各部に電源7が供給されないため非警戒状態となり、電源スイッチ5’のオン状態では各部に電源7が供給され警戒状態となる。
【0043】
この場合も、遅延回路6を設けることにより、電源スイッチ5’がオンされた時点から所定の時間内は各部に電源が供給されず非警戒状態が維持され、所定の時間経過後に各部に電源が供給され警戒状態が開始される。
【0044】
電源スイッチ5’を設けることにより、無線送信器A2の電池寿命を延ばすこともできる。
【0045】
(実施形態3)
本実施形態における基本構成は実施形態1と共通するために共通する部分については同一の符号を付して説明を省略し、本実施形態の特徴となる部分についてのみ詳細に説明する。
【0046】
則ち本実施形態は、実施形態1に対して、無線送信器Aに無線受信器Bの警戒状態を開始させるための警戒セット釦8を設け、無線受信器Bに、第2の遅延回路15を設けた点に特徴がある。
【0047】
本実施形態の無線送信器A3と無線受信器B1の構成を図6のブロック図に示す。
【0048】
無線送信器A3は、無線送信器Aの振動センサ1と送信側状態判断部2と無線送信部3と感度切替スイッチ4と警戒セット釦8とを備えている。
【0049】
警戒セット釦8は、押操作されると、無線受信器B1の警戒状態を開始させるための警戒セット信号s2を無線送信部3を介して無線受信器B1に送信する。
【0050】
無線受信器B1は、無線送信器Bの無線受信部10と受信側状態判断部11と出力部12と遅延回路14と警戒解除釦13と第2の遅延回路15とを備えている。
【0051】
第2の遅延回路15は、無線受信部10が無線送信部3からの警戒セット信号s2を受信すると、受信した時点から所定の時間(例えば、30秒。)経過した後に受信側状態判断部11を警戒状態へと移行させる。
【0052】
以上のように構成された車両盗難防止システムにおいては、車から降りる際に無線送信器A3の警戒セット釦8を操作すれば、無線送信部3から無線受信部10へ警戒セット信号s2が送信され、第2の遅延回路15により無線受信部10が開始信号s2を受信した時点から所定の時間経過後に受信側状態判断部11が警戒状態へと移行する。
【0053】
よって、外出前に無線受信器B1の警戒状態を解除していても、降車の際に無線送信器A3の警戒セット釦5を操作すれば、再び無線受信器B1の警戒状態が開始され、さらに、第2の遅延回路15により、無線受信部10が開始信号s2を受信した時点から所定の時間経過後に受信側状態判断部11が警戒状態へと移行するので、実施形態2と同様に、前記所定の時間内に降車すれば、降車の際のドアの開閉などによる振動で警報が誤発報されることがない。
【0054】
