ABSTRACT:
A clutch controller that transmits appropriate torque during engaging operation of a clutch and prevents excessive increase or decrease in engine speed. The clutch controller performs request follow-up control under which a clutch actuator is actuated based on a difference between actual transmission torque that is transmitted from a drive-side member to a driven-side member of a clutch, and request transmission torque that is determined based on a rider's accelerator operation, such that the actual transmission torque approximates the request transmission torque. In an operation range in which engine torque increases as engine speed increases, the clutch controller performs rotational speed induction control, in place of request follow-up control, under which the clutch actuator is actuated such that engine speed increases or decreases to a predetermined engine speed.
