<p><P>PROBLEM TO BE SOLVED: To provide a working vehicle having a hydraulic control device devised so that a hydraulic clutch to put on and off a transmission inconjunction with manipulated variable of a clutch operation means of such as operation of a clutch pedal does not influence upon operation feeling of the clutch operation means. <P>SOLUTION: This travelling vehicle is furnished with the hydraulic control device 100 to change hydraulic pressure until a connected state from an unconnected state for each of the hydraulic clutches by estimating a reduction ratio until a clutch shaft of the relative hydraulic clutch from an engine output shaft 1 for each of a plurality of the hydraulic clutches (D,...) and the number of rotation of the relative hydraulic clutch in accordance with a detected value of a rotation number sensor 122 of the engine output shaft 1, correcting thrust of a clutch piston by influence of centrifugal force generated by rotation of the relative hydraulic clutch for each of the hydraulic clutches and correcting hydraulic pressure of hydraulic oil for each of the hydraulic clutches in accordance with the corrected value. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
