摘要： ECU executes in-neutral control in a case where a first clutch is brought into a half-engagement state on the basis of execution of neutral control. During the in-neutral control, ECU detects engine speed and input-shaft rotating speed, and detects differential rotation before an oil pressure change. Subsequently, in a case where the differential rotation before an oil pressure change detected by ECU has exceeded a first differential rotation threshold value, the operating oil pressure for a hydraulic servo is reduced by the first oil pressure.
