To provide a wheel speed calculation device capable of accurately calculating the latest wheel speed even when the latest wheel speed changes suddenly.SOLUTION: A wheel speed calculation device comprises a sensor unit 1 for sequentially detecting that a rotating body has rotated by a predetermined amount and converting to a signal, a data processing unit 2 for shaping the signal converted by the sensor unit 1, generating a pulse signal, measuring and recording a pulse width of the pulse signal, a pulse width updating unit 3 for updating a predetermined number of pulse widths obtained by excluding latest pulse width from a plurality of pulse widths based on the latest pulse widths among of the plurality of pulse widths recorded in the data processing unit 2, and a wheel speed calculation unit 4 for calculating a wheel speed by dividing a rotation amount required for detecting an added pulse width by a value obtained by adding the predetermined number of pulse widths updated by the pulse width updating unit 3 and the latest value.SELECTED DRAWING: Figure 1

    【課題】最新の車輪速が急変した場合にも、最新の車輪速を精度良く演算できる車輪速演算装置を提供する。【解決手段】回転体が所定量を回転したことを逐次検出して信号に変換するセンサ部1と、センサ部1により変換された信号を整形してパルス信号を生成し当該パルス信号のパルス幅を計測して記録するデータ処理部2と、データ処理部2に記録された複数のパルス幅のうち最新のパルス幅に基づいて前記複数のパルス幅から前記最新のパルス幅を除いた所定数のパルス幅を更新するパルス幅更新部3と、パルス幅更新部3により更新された前記所定数のパルス幅と前記最新値を合算した値により、合算したパルス幅を検出するために要した回転量を除して車輪速を演算する車輪速演算部4と、を備える。【選択図】図1
