Gear-change control device, straddle-type vehicle, and gear-change control method

摘要

To provide a gear-change control device for a straddle-type vehicle in which a friction clutch is operated by an actuator which can improve acceleration performance and prevent degradation of the ride quality at the time of gear change. A gear-change control device actuates an actuator in response to an input of a gear-change command and sets the clutch in an intermediate state between the engaged and disengaged states before a plurality of gears in the transmission are selectively engaged by dog clutches. In the intermediate state, a driving-side friction member and a driven-side friction member of the clutch are pressed against each other at a pressure lower than in the engaged state. The gear-change control device actuates the clutch actuator to restore the friction clutch set in the intermediate state to the engaged state after the plurality of gears are selectively engaged.
