Patent ID: 8636621

Claim:
A control device of a vehicle comprising: a transmission mechanism that includes a plurality of rotating elements rotated by torque output and transmitted from a plurality of power sources, and that switches a transmission mode according to engaging states of the respective rotating elements; and a transmission mode changing unit that includes a first engaging member and a second engaging member having a backlash between them in a rotating direction thereof, and that alters the transmission mode to a fixed transmission ratio mode by engaging the first engaging member, connected to one of the rotating elements, with the second engaging member, and alters the transmission mode to a continuously variable transmission ratio mode by releasing the engagement, wherein when a direction of rotating torque acting on the first engaging member is reversed, rotation restraining torque is generated at the first engaging member by using torque output from at least one of the power sources until the backlash has been completely taken up as the direction is reversed, the rotation restraining torque being against, in reverse direction to, and smaller in absolute value than the reversed rotating torque acting on the first engaging member.
