Summary:

An electronically controlled belt-type CVT (Continuously Variable Transmission) has been developed for scooter type two-wheeled vehicles. Related to two-wheeled vehicles, the electronically controlled belt-type CVT has advantages over the conventional belt-type CVT, such as more compact and lighter weight. This was achieved by developing a new rubber belt-type. The new rubber belt-type CVT uses a rubber belt with high friction coefficient and pulleys made of aluminum. To obtain good shifting characteristics, the desired speed ratio related to throttle opening and drive speed is calculated. When moving, the actual speed ratio automatically adjusts to the desired value. For the shift modes, three shift modes, two automatic modes and one manual mode with six-speeds were prepared. The electronically controlled CVT increased the range of usable engine speeds compared to the conventional belt-type CVT. Therefore good drivability is maintained. Good fuel consumption, exhaust emission, low noise were also achieved. By pressing the switches located on the handlebar the riders can change the shift mode according to the situation. The switches are arranged on the handlebar close to the hand for easy hand operation
