<p>[PROBLEM TO BE SOLVED] TO REDUCE A SHOCK GENERATED AT A CLUTCH ENGAGEMENT MOMENT IN A GEARSHIFT OPERATION IN A STRADDLE TYPE VEHICLE (10) USING A COMMON ACTUATOR (75) TO DRIVE BOTH OF A CLUTCH (37) AND A SHIFTER (38) AND TO ENHANCE THE RIDE FEELINGS OF THE VEHICLE. [SOLUTION] A MOTORCYCLE (10) HAS A GEARSHIFT CLUTCH (37), A GEAR SHIFTER (38), A SHIFT SHAFT (70) ROTATED BY THE DRIVING FORCE OF AN ACTUATOR (75), AND A POWER TRANSMITTING MECHANISM OPERATING THE GEARSHIFT CLUTCH (37) AND THE GEAR SHIFTER (38) TOGETHER WITH THE ROTATION OF THE SHIFT SHAFT (70) WHEN A GEARSHIFT OPERATION IS MADE. WHEN AN ENGINE SPEED REACHES OR EXCEEDS A PRESET VALUE IN A SHIFT UP OPERATION, AN ECU (100) OF THE MOTORCYCLE (10) EXECUTES AN ENGINE OUTPUT REDUCING PROCESS IN WHICH AN ENGINE OUTPUT IS REDUCED TO BE LESS THAN THE OUTPUT GIVEN WHEN THE ENGINE SPEED DOES NOT REACH THE PRESET VALUE.</p> |
