Clutch controller, method for controlling clutch, and straddle-type vehicle

A clutch controller comprising:

• an actuator for changing a degree of engagement between drive-side and driven-side members of a clutch that are downstream of an engine in a torque transmission path;
• an actual torque obtaining section for obtaining torque transmitted from the drive-side member to a downstream mechanism of the torque transmission path as actual transmission torque, the downstream mechanism including the driven-side member;
• a request torque obtaining section for obtaining torque determined based on a rider's accelerator operation as request transmission torque;
• an engine torque obtaining section for obtaining torque outputted from the engine as engine torque;
• and
• a control unit for performing a first control under which the actuator is actuated based on a difference between the actual transmission torque and the request transmission torque, such that the actual transmission torque approximates the request transmission torque,
• wherein the control unit determines whether or not the engine operates in a predetermined operation range, and depending on the determination result, performs a second control under which the actuator is actuated such that the actual transmission torque approximates the engine torque, in place of the first control.
