Modification in the Design of ECU of a Motor Vehicle to Control the Speed Depending on the Density of Vehicle

Abstract

The need of a vehicle either a two wheeler or a four wheeler has become a necessity for almost all middle class and upper class people in these days. This leads to several problems in the city like traffic jam, accidents, air polutions etc. Because of the density of vehicles in the city we find more and more accidents especially with the two wheelers, three wheelers and four wheelers. The main reason for the accidents in the city is the over speed without caring the movement of the other vehicles. The rider/driver is not bothered about the density of vehicles in the city. In this paper a suggestion is given to a special design for an Engine Control Unit (ECU) which will control the firing of engine based on the density of a vehicle in the city along with the accelerator given by the rider/driver. The paper suggests the government authorities to adopt a mobile SIM exclusively for each vehicle based on the vehicle registration number which should not be transferable. Using GPS techniques the entire information of the vehicle like speed in kmph, longitude, latitude, timing factor etc. should be monitored by the central server using the SIM and the server should send the maximum speed limit for that vehicle depending on the density of vehicles in the corresponding area. The ECU system should receive this maximum speed limit from the central server and the vehicle should not cross the limit even though the rider/driver raises the accelerator of the same. This technique will definitely reduce the accidents and gives a hassle free driving for all.
