Zusammenfassung:In a vehicle in which a continuously variable transmission, which is connected to an electric motor via a clutch, is operated using oil pressure of an oil pump driven by the electric motor, erroneous engagement of the clutch is quickly determined. The vehicle has the electric motor (2) serving as a vehicle driving source, the oil pump (50) connected to the electric motor (2), the hydraulically-operated continuously variable transmission (3) that uses the oil pressure from the oil pump (50), the clutch (7) interposed between the electric motor (2) and the continuously variable transmission (3), a clutch control means (30) for controlling the clutch (7) such that the clutch enters into a completely engaged state, a slip-engaged state, or a release state, and a vehicle control means (10) for controlling the electric motor (2) such that the electric motor rotates at a target rotation speed. Also provided is an erroneous engagement handling control means (34) that executes torque adjustment control to decrease an output torque of the vehicle driving source when it is determined that the clutch (7) is in an erroneously engaged state where the clutch (7) is erroneously completely engaged.
