PROBLEM TO BE SOLVED: To provide an axle rotation detection pulse counter capable of accurately counting pulses of pulse signals to be output from an axle rotation detection part, and a tire position determination system.SOLUTION: Pulse signals Spl are input in an axle rotation detection pulse counter 23 from axle rotation detection parts 22a-22d provided in respective axles 18a-18d, and these pulse count values are counted. The axle rotation detection pulse counter 23 acquires travel information Ddr through CAN, etc., and counts the pulse count values on the basis of the acquired travel information Ddr when the pulse count values of the respective axles 18a-18d are counted. Specifically, the pulse count values are counted by adding count values when a vehicle 1 travels forward, and subtracting the count values when the vehicle 1 travels backward.

    【課題】車軸回転検出部から出力されるパルス信号のパルスを精度よく計数することができる車軸回転検出パルス計数装置及びタイヤ位置判定システムを提供する。【解決手段】車軸回転検出パルス計数装置23は、各車軸18a〜18dに設けられた車軸回転検出部22a〜22dからパルス信号Splを入力し、これらのパルス計数値を計数する。車軸回転検出パルス計数装置23は、各車軸18a〜18dのパルス計数値を計測するにあたり、CAN等を通じて走行情報Ddrを取得し、それに基づいてパルス計数値を計数する。具体的には、車両1が前進するときはカウント値を加算し、車両1がバックするときはカウント値を減算することにより、パルス計数値を計数する。【選択図】図1
