摘要： A power transmission apparatus includes a shift drum, a clutch, a clutch lifter, and a transmission body. The shift drum makes a dowel be extracted/inserted between a shifter and a shift gear. The clutch has first friction plates and second friction plates. The first friction plates rotate around a main shaft by receiving power from a crankshaft. The second friction plates are disposed alternately with the first friction plates and are relatively non-rotatably supported by the main shaft. The clutch lifter is displaced between a connection position at which power is transmitted by the clutch and a disconnection position at which the transmission of the power is disconnected. The transmission body transmits a driving force to the shift drum while the clutch lifter moves from the connection position to the disconnection position, in accordance with rotation of a shift spindle that rotates in accordance with a driving force.

摘要： A shift position detecting device that determines a shift position based on a detection logic formed of a combination of turning on or off of a plurality of switches that are fixedly arranged at least one by one at positions corresponding to a plurality of detecting object portion rows mounted on a shift drum. An accurate shift position can be detected even if there is an irregularity in switching timings of switching modes of the plurality of switches. A shift position detecting member establishes the shift position as a new shift position and outputs shift position information, while when the detection logic after the transition is a detection logic other than the detection logic corresponding to the changeable shift position, sets the new shift position not yet established and outputs information corresponding to non-establishment of the shift position.

摘要： A basic clutch capacity calculating unit calculates a clutch capacity of the DCT applying an engine speed, a degree of throttle opening, and a front wheel vehicle speed to a map. The basic clutch capacity calculating unit further calculates the DCT basic clutch capacity by amending the basic clutch capacity based on an oil temperature and a water temperature. An NE converted value calculating unit calculates an NE converted value obtained by converting a vehicle speed into an engine speed with the front wheel vehicle speed and a DCT speed change stage as input parameters. A hunting detecting unit detects hunting by comparing the engine speed with the NE converted value when a throttle operation is detected. A DCT clutch capacity correcting unit makes decreasing correction of a DCT clutch capacity when hunting is detected for suppressing the hunting.

摘要： In a rough terrain vehicle, at a time of preparing to start movement, in a case that a left paddle switch and a right paddle switch are operated together with an accelerator pedal, an ECU disengages a clutch of an automatic transmission, and causes an output of an engine to increase. On the other hand, at a time of starting movement, in a case that the left paddle switch and the right paddle switch are returned to their initial positions, the ECU engages the clutch and transmits the output of the engine from the engine to vehicle wheels via the automatic transmission, to thereby rapidly start movement of the rough terrain vehicle.

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.
