Abstract
In a departure standby state in which a transmission is shifted to a drive stage and a mechanical clutch is disengaged, if a vehicle speed is greater than or equal to a predetermined value, the transmission is shifted to the neutral, and then the mechanical clutch is engaged. Then, it is determined whether the transmission is being rotated in reverse or not based on a rotational fluctuation on the driving side or the driven side in the process for engaging the mechanical clutch. When an accelerator pedal is pressed down at an angle greater than or equal to a predetermined angle, or when a gear shift instruction is input from the shift lever, if the transmission is being rotated in reverse the transmission is inhibited from being shifted to the drive stage, while if the transmission is not being rotated in reverse the transmission is shifted to the drive stage according to the pressed down state of the accelerator pedal, or a gear shift in instruction.
