<p>PURPOSE:To reduce shock at the start and/or speed change of a vehicle by selecting the most suitable property from plural preset hydraulic waveform curved lines according to the operating position detected of an axle pedal so as to control a clutch control valve. CONSTITUTION:The operating position of an axle pedal 10 is detected by a limit switch 12 while being classified into an axle-off position A, a half-axle position B, and a full-axle position C. A controller 8 selects the most suitable property from plural preset hydraulic waveform curved lines according to axle signals A-C detected, and hydraulic pressure to the hydraulic clutch 5 of an automatic transmission 3 is controlled via a driving circuit 9 and a clutch control valve 7, following the property. Sudden start and/or sudden acceleration of a vehicle is thus enabled and also shock at the start and speed change of the vehicle reduced.</p> |
