Automobiles are the major mode for the transportation, in this current era. Due to the technological advancements there were lot of new upgrades, new safety features available which comforts the driver and also the passengers. Many modern vehicles were introduced with new features like automatic door locking system, Temperature stabiliser, window closing systems, power steering system, Anti-lock Braking Systems, ESP’s etc. Manual engagement of clutch while shifting between the gears in traffic areas is a hectic job for drivers. This project is proposed to avoid the necessity of pressing the cutch plates while changing gears. The semi-automatic clutch system comprises a switch in the gear rod knob. With this switch the driver controls the clutching operation. The controlling is done with a Propotional Control Valve and the actuation by a double acting cylinder. The positioning of the clutch is done by the pneumatics by using metering out circuit. Hence engaging of the clutch is done semi-automatically by this mechanism and the retraction of the pneumatic cylinder is achieved smoothly. Instead of pressing the clutch manually, the engagement and disengagement of the clutch is done semi automatically. Driver indeed will be experiencing more comfort in two pedal systems than in common three pedal systems. This project will be much comfortable for amputees who have the spirit of driving heavy vehicles.
