Abstract
A vehicular drive system provided with an electric motor for generating a drive force to be transmitted to drive wheels, includes: the electric motor including an output rotary member having opposite end portions from which the drive force of the electric motor is transmitted to the drive wheels; two power connecting/disconnecting devices respectively configured to selectively connect and disconnect each of the opposite end portions of the output rotary member to and from the drive wheels; and the two power connecting/disconnecting devices being controlled to selectively connect the opposite end portions of the output rotary member to the drive wheels, for thereby changing a ratio of rotating speeds of the drive wheels to an operating speed of the electric motor.
