Abstract

DC60 to reduce jerk generated at the clutch stroke in vehicle gear shifting. A straddle type with a gearshift control device that provides clutch and shifting operations. Gear by using the actuator power And to enhance the driving feeling of the vehicle The actuator is controlled according to the rotation position and the speed of the shift shaft when the rotation position of the shift shaft is between the first and the second position. The replacement shaft will Is rotated at a speed lower than the speed at which the shift shaft is rotated first to the Connect the clutch to shift gears at low speed. The first and second positions are set in a At the clutch, the gearshift is halfway connected when the shift shaft is in the rotation position. Between the first and second position (problem) to reduce the jerk generated at the clutch stroke when shifting in a vehicle. A straddle type with a gearshift control device that provides clutch and shifting operations. Gear by using the actuator power And to enhance the driving feeling of the vehicle (Method for correction) The actuator is controlled according to the rotation position and the speed of the shift shaft when the rotation position of the shift shaft is between the first and the second position. The replacement shaft will Is rotated at a speed lower than the speed at which the shift shaft is rotated first to the Connect the clutch to shift gears at low speed. The first and second positions are set in a At the clutch, the gearshift is halfway connected when the shift shaft is in the rotation position. Between first and second position
