Abstract:
1. A vehicle comprising: an engine; a continuously variable transmission that receives a torque from the engine, the continuously variable transmission including a stationary sheave, a movable sheave provided opposite to and capable of moving relative to the stationary sheave, and an actuator that moves the movable sheave; a control device arranged and programmed to drive the actuator to control a clamping force that is a force to clamp a belt with the stationary sheave and the movable sheave; a drive wheel that receives a torque from the continuously variable transmission; and a torque damping mechanism provided on a torque transmission path between the continuously variable transmission and the drive wheel, to delay timing of transmission of torque fluctuation with a negative angular acceleration occurring at a downstream torque transmission member positioned downstream of the torque damping mechanism to an upstream torque transmission member positioned upstream of the torque damping mechanism, in which a rotation direction of the downstream torque transmission member is defined as positive; wherein the control device includes: a state information obtaining unit that obtains information indicating a state of the torque damping mechanism; and a clamping force changing processing unit that changes the clamping force based on the state of the torque damping mechanism.
