ABSTRACT:
Riding comfort of a vehicle is improved by reducing deceleration and acceleration exceeding the expectation of a rider due to gear changes. A gear change control device calculates current torque being transmitted from a drive-side member of a clutch to a driven-side member of the clutch, and calculates post-completion torque estimated to be transmitted from the drive-side member to the driven-side member after the completion of engagement of the clutch. The gear change control device then controls the degree of engagement of the clutch according to the difference between the current torque and the post-completion torque, and receives a next gear change command according to the difference between the current torque and the post-completion torque.
