Abstract

A vehicle drive unit to prevent a single phase lock of a motor as a prime mover to limit damage is provided. The drive unit includes: a first transmission route to deliver drive force of an engine to drive wheels; and a second transmission route to deliver drive force of a motor to the drive wheels. The second transmission route comprises an intermediate shaft that transmits the drive force of the motor to the first transmission route. A fluid coupling is disposed between the motor and the intermediate shaft. A lockup clutch is arranged parallel to the fluid coupling between the motor and the intermediate shaft.
