Claims (4)
- 複数のホイールにそれぞれ装着されタイヤの空気圧情報を含む信号により変調された電磁波を送出するセンサ装置と、車両に装備されこの電磁波を受信する受信アンテナと、この受信アンテナに受信された電磁波から前記空気圧情報を復調する受信機と、その空気圧情報に応じて運転席に警報を送出する手段とを備えたタイヤ空気圧警報装置において、
前記受信アンテナは、その指向特性の最も有効な角度が前記センサ装置から送信され路面に反射した電磁波に対して向けられたことを特徴とするタイヤの空気圧警報装置。 - 前記受信アンテナは、一または複数の前軸に装着された複数のホイールにそれぞれ設けられた前記センサ装置が送出する電磁波を受信するために車両前方下部に共通に1個が設けられた請求項1記載のタイヤの空気圧警報装置。
- 前記受信アンテナは、一または複数の後軸に装着された複数のホイールにそれぞれ設けられた前記センサ装置が送出する電磁波を受信するために車両側部の左右にそれぞれ1個ずつが設けられた請求項1記載のタイヤ空気圧警報装置。
- 前記受信アンテナは、金属板の打ち抜き加工によりループ状に形成され、受信機の要部回路とともにプラスチック製筐体の内部に実装された構造である請求項1記載のタイヤ空気圧警報装置。
