The world is moving towards a cleaner and sustainable technology, an electric car is one of them. Nowadays most of the electric cars are using manual transmission which can be converted in to semi-automatic and automatic transmission by installing an electro-pneumatic shifting mechanism. In this article, work concerning about the product design of shifter on a sequential transmission is described. The mechanism is achieved by using a pneumatic cylinder, sensors, solenoid valves, air reservoir, microcontroller and paddle shifter. The gears can be shifted either by the driver or an electronic control unit (ECU) on a real time basis. ECU takes input from the paddles attached behind the steering wheel or vehicle speed sensor and the gear is shifted by the pneumatic cylinders, controlled by a control unit through the solenoid valves. Numerical results for the automated shifting system in the vehicle show an increment of 26% in the top speed and 28% in the average power along with improved cornering velocity with respect to the vehicle without shifter. The automated shifting mechanism is much more helpful for straight line path as it changes the gears to achieve maximum acceleration in minimal time. This Electro-Pneumatic shifter setup is cost effective and gives an excellent opportunity to have a feel of driving a sports vehicle.
