Electronic automatic gear shifting system for a motorcycle

Abstract

Motorcycle is widely used around the world and particularly in Pakistan. The gear shifting system of the motorcycle is conventionally manual. This paper covers development of an indigenous automatic gear shifting/changing system for the standard motorcycle. By this system the manual mechanicalgear-shifting system will remain unchanged because an additional electro-mechanical system is placed on the vehicle to shift the gear and for automatic controlling the clutch. So the system has both the options manual as well as automatic. This system uses low-cost microcontrollers to make the accurate decision for shifting the gear up and down by observing the speed, and it controls the clutch transmission where necessary. The complete hardware and software has been tested and the functioning of the automatic gear shifting system is verified. This system is flexile and can be used with any motorcycle manufactured in Pakistan ranging from 50cc to 200cc. © 2008 Springer-Verlag.
