摘要： A motorcycle includes a transmission, a first measuring unit, a second measuring unit, and a controller. The transmission is configured to automatically shift gears between a driving shaft and a driven shaft to transmit power from the driving shaft to the driven shaft. The first measuring unit is configured to measure the magnitude of a roll angle of a vehicle body. The second measuring unit is configured to measure the angular velocity of the roll angle of the vehicle body. The controller is configured to inhibit the transmission from shifting gears, based on the magnitude and the angular velocity of the roll angle. This configuration provides a motorcycle that enables gear shift control with more detailed response to a situation of a vehicle body.

摘要： A driving force control device for saddled vehicle includes a transmission that transmits driving force of an engine to a driving wheel of a vehicle at predetermined reduction ratio; a clutch that connects/disconnects the driving force between the engine and the transmission; and a controller that controls the transmission and the clutch. The controller permits selection of a normal mode in which the reduction ratio of the transmission is varied according to a running condition and a slow mode permitting slow forward movement and slow backward movement by varying the reduction ratio of the transmission to a fixed reduction ratio according to predetermined operation, and the controller holds the clutch in a partial clutch engagement condition so as to prevent the vehicle from moving forward or backward when the slow mode is selected and no predetermined operation is performed.
