Automatic Vehicle Speed Control: An Assistance for Accident Avoidance

Looking at the current scenario; increasing the speed of vehicles causes a lot of accidents and eventually a lot of deaths. The government has made it compulsory for all the transport vehicles in India to follow a maximum speed of 80 km per hour on highways. For this reason, the use of Speed Governors is made. Everywhere in the country, we find such zones that have certain speed limits. The objective of our research work is to develop an automatic speed control in which the speed of the vehicle in a particular zone will automatically be reduced to the specified speed of the concerned zone. We have detected the initial speed of the vehicle in the zone and the position of the accelerator. Upon detection, the position of the throttle valve is controlled. In turn the air to fuel ratio is controlled which controls the speed of the vehicle. The implementation of this prototype is not only possible on highways, but also on local roads to avoid accidents in the city as well.
