A shift drum angle detecting device includes: a first angle sensor configured to output a first sensor output value corresponding to a shaft rotational angle of a first sensor shaft integrally rotating with a shift drum; and a second angle sensor configured to output a second sensor output value corresponding to a shaft rotational angle of a second sensor shaft rotating at an increased speed as a result of a speed increasing mechanism increasing the rotation of the first sensor shaft. A first sensor switching angle where the maximum value and the minimum value of the first sensor output value are switched and a second sensor switching angle where the maximum value and the minimum value of the second sensor output value are switched are set to be different from each other in rotational angle of the shift drum. Such device precisely detects any rotational angle of the shift drum.

A gear shift control system controls an actuator so that a pushing force will be a constant gearing-phase pushing force, during a gearing phase. The gear shift control system performs control on the basis of the number of rotation of the engine in the gearing phase, which is measured at the start of the gearing phase, so that the constant gearing-phase pushing force will increase as a number of rotation of the engine in the gearing phase increases. Thus, the hitting sound due to collision between the sleeve and the shift gear in shifting gears is reduced.

A power transmission device for a vehicle includes a control unit adapted to automatically control engagement or disengagement of a clutch, and is further equipped with a clutch lever for manually engaging or disengaging the clutch. The power transmission device includes a manual mode in which the clutch is engaged or disengaged by a driver performing an engagement or disengagement operation with the clutch engagement/disengagement operating element and an automatic mode in which the clutch is engaged or disengaged under the control of the control unit without the driver performing the engagement or disengagement operation. The manual mode or the automatic mode is selectable by the driver. In the manual mode, it is further possible to select a plurality of control modes with differing levels of intervention of the automatic control.

A synchronizer-mechanism-equipped transmission capable of moving tips of sleeve teeth and ring teeth away from butting each other by moving a synchronizer sleeve with biasing means even if the tips of the sleeve teeth and ring teeth are in contact when actuator driving stops. When sleeve teeth of a synchronizer sleeve that moves during gear shifting are located at a first synchronization position where the sleeve teeth begin to come into contact with ring teeth, a pressing member of a detent mechanism is in contact with a pre-gear-shifting detent recessed portion of a star cam.

Synchronizer-mechanism-equipped transmission

A twin-clutch transmission that can always effectively reduce gear shift shock and a collision sound even under the existence of variation attributed to component tolerance and change over the ages attributed to wear. A twin-clutch transmission calculates a rotational speed difference (|Na&#x2212;Nb|) between an odd-stage main shaft rotational speed (Na) and an even-stage main shaft rotational speed (Nb) and learns synchronization start gear shift drive displacement (&#x3b8;s) detected by a gear shift drive displacement detecting unit at the timing at which the rotational speed difference (|Na&#x2212;Nb|) reaches a predetermined synchronization start determination rotational speed difference (Ds) from gear shift start. The twin-clutch transmission controls an actuator on the basis of the learned synchronization start gear shift drive displacement (&#x3b8;s).

The variable speed control system further includes an engine revolution speed detection sensor which detects an engine revolution speed. The control unit changes the pedal load threshold according to the engine revolution speed detected.
