A Combined Pedal for Brake and Accelerator

The present paper deals with design, construction and working of Accelerator and Brake operated by one pedal, which may be a technique for reducing road accidents. The main objective of this innovation is to eliminate the operator’s risk of pressing the wrong pedal at the time of emergency as well as reduction in the driver’s reaction time to switch from accelerator to brakes or vice versa. This new mechanism is designed in such a way that it can be used in any type of automotive vehicle. The mechanism used for combined brake and accelerator is simple and can be adopted conveniently. At the present time automobiles are equipped with independent pedal controls for operating the accelerator and brake, these pedals being operated by right foot, and since the two functions are opposed and incompatible it is necessary to leave one pedal free in order to operate the other. It can therefore be supposed that some drivers have difficulty in removing their foot from the accelerator pedal and transferring it to the brake pedal quickly in emergency situations. To solve this problem, a new brake pedal and accelerator system is designed. The detailed design of combined pedal mechanism is modelled using CATIA V5 R20. Then a prototype has been prepared which confirms the required mechanism and finally tested for its working. Therefore, it gives an optimized design for new combined pedal mechanism. Hopefully this project will help everyone to understand how implemented mechanism works more efficiently, which can help to reduce the accident that may happen in each day.
