ABSTRACT:
An anti-creep control apparatus has a forward clutch control section that controls the hydraulic pressure of a forward clutch so as to slip the forward clutch when an automatic transmission is set in a drive range and the vehicle is stopped. The anti-creep control apparatus sets a target engagement time that is inversely proportional to the engine rotation speed at the time just before starting anti-creep control. The anti-creep control apparatus controls an oil pressure modulator so that one of a slip amount of the forward clutch and the output shaft rotation speed of the torque converter becomes nearly zero when the target engagement time elapses.
