CONTROLLER AREA NETWORK AS THE SECURITY OF THE VEHICLES

ABSTRACT Automobile industry is buzzing about avoidingvehicle theft in the present. By making use of the GPS feature in the mobile phone the design and development of a theft control system for an automobile can be achieved. In this system mobile phone used is embedded in the vehicle with an interfacing to Engine Control Module (ECM) through CAN (Controller Area Network) Bus. This in turn is communicated to the ECM. By using the GPS feature of mobile phone the owner of the vehicle being stolen can stop the vehicle and this information is also used by the owner for future processing. The owner can send a message to the mobile which is embedded in the vehicle which is stolen and in turn can control the vehicles engine by locking the working of the engine. Through CAN Bus, the developed system accept the message send by the owner and this is broadcasted to the vehicles network. The locked engine can be unlocked only by owner by sending the message again. Also as soon as the engine is locked all the windows of the vehicle get locked and a poisonous gas comes through AC and thief becomes unconscious. This prevents the thief from escaping in any way. The goal behind the design and the system is to develop security for vehicles
