To calculate the speed of a vehicle accurately in real time.SOLUTION: A wheel rate detector 12 includes: a wheel rate sensor 44 using a pulsar ring rotatably and integrally attached to a front wheel; a pulse-vehicle rate converter 62 for generating a raw vehicle rate signal Vp from a pulse signal Sp detected by the wheel rate sensor; and a vehicle rate signal calculation unit 64 for correcting the raw vehicle rate signal in consideration of information related to the eccentricity to the vehicle axis of the pulsar ring and calculating a vehicle rate signal V with less eccentricity noise caused by eccentricity.SELECTED DRAWING: Figure 4

    【課題】車速を高精度かつリアルタイムに算出する。【解決手段】車速検出装置12は前輪に一体的に回転可能に取り付けられたパルサーリングを用いた車輪速センサ44と、車輪速センサにより検出されたパルス信号Spから原車速信号Vpを生成するパルス・車速変換器62と、パルサーリングの車軸に対する偏心に関連する情報を考慮して原車速信号を補正し、偏心を原因とする偏心ノイズを低減した車速信号Vを算出する車速信号算出器64と、を備える。【選択図】図4
