Abstract
Description
図1(a)に示すように、タイヤ状態監視装置としてのタイヤ状態監視システム30は、車両10に搭載されている。まず、車両10について説明する。
図1(a)に示すように、タイヤ状態監視システム30は、4つの車輪11にそれぞれ装着される4つの送信機31と、車両10に設置される受信機50とを備える。送信機31は、タイヤ13の内部空間に配置されるように、車輪11に取り付けられている。送信機31としては、タイヤバルブに固定されたものや、ホイール12やタイヤ13に固定されたものが用いられる。送信機31は、対応するタイヤ13の状態(例えば、タイヤ空気圧やタイヤ内温度)を検出して、検出したタイヤ13の情報を含む送信データを受信機50に無線送信する。タイヤ状態監視システム30は、送信機31から送信される送信データを受信機50で受信することで、タイヤ13の状態を監視する。
なお、検出軸34a以外にも検出軸を有する多軸の加速度センサ34の場合には、それぞれの検出軸に作用する加速度が個別に検出される。以下の説明において、加速度センサ34によって検出される加速度とは、検出軸34aによって検出される加速度を示す。
図1(a)に示すように、受信機50は、受信制御部51と、受信回路52と、受信アンテナ56とを備える。受信制御部51には、車両10に搭載された表示器57が接続されている。受信制御部51は受信CPU54及び受信記憶部55(ROMやRAM等)を含むマイクロコンピュータ等よりなる。受信制御部51は、計時機能を備える。計時機能は、例えば、タイマや、カウンタによって実現される。受信回路52は、各送信機31から受信アンテナ56を介して受信された無線信号を復調して、送信データを受信制御部51に出力する。受信回路52が受信部として機能する。
(1)受信制御部51は、特定角度同士の角度差(等角度)を用いて取得回転角度を補正または変換する。これにより得られた特定回転角度は、一定角度(1つの特定角度)で送信された送信データの受信を契機として取得された回転角度とみなすことができる。したがって、取得回転角度を補正することなく各送信機31がいずれの車輪11に装着されているかを特定する場合に比べて、各送信機31がいずれの車輪11に装着されているかの特定に要する時間の短縮化が図られる。
・特定回転角度の算出態様は、剰余演算以外であってもよい。受信制御部51は、取得回転角度が180度以上の場合には、取得回転角度から180度を減算することで特定回転角度を得てもよい。この場合、受信制御部51は、取得回転角度が180度未満の場合には、そのままの値を特定回転角度とする。
・実施形態では、パルスカウント値を回転角度に変換して、各種処理を行ったが、パルスカウント値が回転角度を示していることを考慮すれば、パルスカウント値を用いて処理を行うこともできる。例えば、特定回転角度は、取得されたパルスカウント値を48で剰余演算することで得ればよい。「回転角度」とは、回転角度そのものに限られず、回転角度を示すパラメータであればよいといえる。
