Abstract

A starting clutch control device controls such that the transmission torque capacity of a starting clutch (clutch torque) becomes a value required to transmit a torque equal to an engine absorption torque at the time of power-off running. A control of gradually increasing a clutch torque is carried out with a delay after an accelerator pedal is depressed during power-off running, to thereby prevent the occurrence of surging vibrations when an accelerator pedal is abruptly depressed during power-off running.
