Beschreibung
Zusammenfassung:	On an automatic transmission (3) equipped with a first clutch engaged at startup time, a brake engaged together with the first clutch at two-speed stage, and a second clutch engaged together with thefirst clutch at three-speed stage, especially when it is determined that a path is flat in performing neutral control, a three-speed stage state is placed by the second clutch without carrying out Hill hold by the brake. During neutral control, braking never causes rotating parts in a transmission mechanism to be fixed to a transmission case, thereby preventing idle vibration of an engine from being transferred from the transmission mechanism.Further, higher change gear ratio of an automatic transmission mechanism (5) reduces amplification of idle vibration, resulting in vibration transferredto drive wheels being alleviated.
