Abstract
When an N position sensor is ON, even though the N position is selected, the oil pressure supplied to a clutch C1 which is engaged during the transition from the non-running state to the running state is raised in advance to a predetermined oil pressure; and, if a running request is detected when a D position decision has not been made, irrespective of whether or not a shift lever has been shifted from its N position to its D position, first speed starting off from rest control is performed, in which the oil pressure supplied to the clutch C1 is raised to an oil pressure at which the clutch C1 is capable of power transmission.
