RFID BASED PROTOTYPE DEVELOPMENT OF IMMOBILIZER FOR TWO WHEELER VEHICLE SECURITY

Abstract

An immobilizer is an electronic device fitted to an automobile which prevents the engine from running unless the vehicle has the proper access to it. The main use of this system is to protect the vehicle from being stealth as it deactivates the engine. The immobilizer security system is mainly seen in four wheeler vehicles. The same idea can be implemented for 2 wheeler vehicles which are in huge number in countries like India and Japan, as the vehicles are being stolen very frequently. Early models of immobiliser used a static code in the ignition key itself in place of a remote RFID tag, which was recognized by an RFID loop around the lock barrel and checked against the vehicle's Engine Control Unit (ECU) for a match. If the code is unrecognised, the ECU will not allow fuel to flow and ignition to take place. When the ECU determines that the coded key is valid then the ECU activates the fuel-injection sequence. The aim of this paper is to develop a prototype for immobilizing the vehicle with the help of RFID. The tag should be in the pocket of the vehicle owner, when the tag comes into the EMF field which is surrounded around the bike. The ID present in the tag has to be read by the reader and compare the id present in the controller. If the ID gets matched then the ignition will turn on or else not. The owner will be having only one ID. In any case if some other tries to start the bike by using other tag having different ID it will not work and the bike will not get started. This unique feature of the prototype adds more security for two wheeler vehicles.
