Experimental Automatic Gear Shifting for a Combustion Race Car

Automatic gear shifting is a process in which an electronic hardware system is installed in the vehicle and the gear shifts automatically when it moves, without the need for any person to manually shift it. This automation is accomplished through the use of a microcontroller as well as the necessary sensors. The automatic gear shifting system is designed to keep the engine running at optimal revolutions per minute (RPM). The transmission must automatically up-shift as the engine revolutions rise above the top limit. This results in the efficient working of the engine, also increasing its longevity making the task of the driver easier. The microcontrollers communicate with the control systems and other components in the car using the Controller Area Network (CAN) protocol. This work discusses the algorithm involved, the sensors used to achieve the perfect output and safe transmission. Comparing the graphs of the manual transmission and automatic transmission. The proposed work also allows shifting from AMT to manual mode with the use of a simple button controlled using the micro-controller. Finally, the modifications required on the existing car models to achieve higher speeds at a shorter period of time and the improvements in a car after the implementation of the concept.
