INTELLIGENT VEHICLE CONTROL BASED ON IDENTIFICATION OF ROAD SIGNS BY SOLAR POWERED RFID TRANSPONDERS

Our paper deals with automatic vehicle speed limit on roads by using solar powered RFID technology to control an automobile. In the present scenario traffic violations are increasing rapidly. It gives rise to major problems which are beyond human control directly and therefore there is a need for automation. An RFID reader present in the vehicle senses the vehicle speed limit on the tag as a reference speed input(attached to the speed limit signboard).Here,the active RFID tag is used in the signboard which is having a battery supplied from the solar panel. This reference speed is given to the electronic control unit. Meanwhile the vehicle speed sensor present in the wheel gives the actual speed of the vehicle on road. The output of this ECU unit is given to the proposed braking system present in the automobiles. We here suggest two braking systems in this paper. It’s having an advantage of not supplying the power to rural area signboards
