Next generation auto theft prevention and tracking system for land vehicles

Automobile theft has been a persisting problem around the world and greater challenge comes from professional thieves. A modern vehicle utilizes remote keyless entry system and immobilizer system as the main weaponry against vehicle theft. But these systems prevent unauthorized access of the vehicle to a certain extent only. Smart gravitational lock is used to prevent the theft by providing the air gesture key from key fob to the vehicle which provides high security to the vehicle. When there is no usage of key fob, then the vehicle is secured by touch screen ignition where the software key gesture is given to the touch screen. GPS and GSM technologies enable the vehicle owners to track and monitor the vehicle at anytime from anywhere. During GPS outage environment, Inertial Navigation Sensor is used that contains 3-axis MEMS magnetometer and accelerometer which inform the vehicle positions to the owner by use of dead reckoning method. To restrict the vehicle movement within a particular area, GPS fencing is used in which fence radius can be programmed in the touch screen display. The integrated motions sensing subsystem is used which measures the vehicles 3-D position and detects if vehicle is moved or tilted, when the threshold level is exceeded. In case of auto theft, fuel supply will be made to cut off slowly by sending the message thereby disabling the vehicle.
