SHIFT CONTROL DEVICE AND STRADDLE TYPE VEHICLE

摘要

SHIFT CONTROL DEVICE AND STRADDLE TYPE VEHICLE [PROBLEM TO BE SOLVED] TO REDUCE A SHOCK GENERATED AT A CLUTCH ENGAGEMENT MOMENT IN A GEARSHIFT OPERATION IN A STRADDLE TYPE 5 VEHICLE HAVING A SHIFT CONTROL DEVICE WHICH MAKES THE CLUTCH OPERATION AND THE GEARSHIFT OPERATION USING THE POWER OF AN ACTUATOR, AND TO ENHANCE THE RIDE FEELINGS OF THE VEHICLE. [SOLUTION] THE ACTUATOR IS CONTROLLED BASED UPON A ROTATIONAL POSITION AND A SPEED OF A SHIFT SHAFT. WHEN THE ROTATIONAL 10 POSITION OF THE SHIFT SHAFT IS LOCATED BETWEEN A FIRST POSITION AND A SECOND POSITION, THE SHIFT SHAFT IS ROTATED AT A SPEED SLOWER THAN A ROTATIONAL SPEED AT WHICH THE SHIFT SHAFT IS ROTATED BEFORE REACHING THE FIRST POSITION TO ENGAGE A GEARSHIFT CLUTCH AT A LOW SPEED. THE FIRST POSITION AND THE SECOND 15 POSITION ARE SET IN SUCH A MANNER THAT THE GEARSHIFT CLUTCH IS IN A HALFWAY ENGAGED STATE WHEN THE SHIFT SHAFT IS LOCATED AT A ROTATIONAL POSITION BETWEEN THE FIRST POSITION AND THE SECOND POSITION.
