ABSTRACT:
An anti-creep control apparatus of an automatic transmission has a forward clutch control section which controls the hydraulic pressure of a forward clutch by slipping the forward clutch when the automatic transmission is set in a drive range and the vehicle is stopped while an engine is operating. The anti-creep control apparatus controls an hydraulic pressure of the forward clutch to be held or increased by a predetermined value when a relative rotation of the forward clutch is detected during the anti-creep control. The controlled hydraulic pressure is set as a lower limit value of the forward clutch hydraulic pressure in a present anti-creep control.
