Abstract
A control device for a transmission including a clutch driven by an actuator mechanism, such as a motor, is provided. The control device controls the actuator so that the rider does not perceive generation of a braking force when the clutch is shifted from a disengaged state to an engaged state while traveling, thereby enhancing riding comfort. In performing the control to actuate a clutch from a disengaged state to an engaged state, the control device makes a determination about whether or not to restrict engagement of the clutch based on information about a rotational speed on an upstream side of the clutch and information about a rotational speed on a downstream side of the clutch. If it is determined that engagement of the clutch is to be restricted, the control device delays engagement of the clutch until the engine speed is increased to an acceptable level.
