Abstract
An ECU is configured to disengage a clutch by driving a motor upon detection of starting of a shift operation, and to engage the clutch upon detection of completion of the shift change. The shift operation starting detection is detected upon determination that an operational force given to a shift pedal is equal to or more than a predetermined operational force, and the shift change completion detection is detected upon determination that a rotational angle of a shift drum from a shift gear position before a shift gear operation becomes equal to or more than a first predetermined angle. The shift operation starting detection is also detected upon determination that the rotational angle of the shift drum from a shift gear position before a shift gear operation is a second predetermined angle or more which is smaller than the first predetermined angle.
