<p><P>PROBLEM TO BE SOLVED: To propose a new readhesion control technique that strikes a balance between an elimination of a noise component and reduction of time delay included in a rotation detection signal. <P>SOLUTION: An acceleration detector 612 for slip and skid detection, an acceleration detector 622 for recovery detection and an acceleration detector 632 for readhesion detection have a differentiation calculator to differentiation-operate a shaft speed V detected by a speed detector 601 and further a smoothing unit to smooth to a time base direction each and detect acceleration but time-widths to smooth are different. Smoothing time width Ta2 of the acceleration detector 622 for recovery detection and smoothing time width Ta3 of the acceleration detector 632 for readhesion detection are determined in narrower time width than that of smoothing time width Ta1 of the acceleration detector 612 for slip and skid detection. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
