The low-frequency current ripple is supplied by the battery which minimizes the effects of such ripple being drawn directly from the PV itself. The single-phase boost inverter is voltage-mode controlled and the dc–dc bidirectional converter is current-mode controlled. In addition, the proposed system incorporates battery-based energy storage and a dc–dc bidirectional converter to support the slow dynamics of the PV. In this project, the boost-inverter topology is used as a building block for a single-phase grid-connected photo voltaic cell (PV) system offering low cost and compactness. When the vehicle is stolen, owner of vehicle may stop the vehicle by just sending a SMS " OFF " to the GSM modem and with the help of SIM tracking knows the location of vehicle and informs to the local police or stops it from further movement. The owner of the vehicle and the central processing system only know this secured password. Again it will come to the normal condition only after entering a secured password. By reading the SMS received by the mobile, one can control the ignition of the engine say to lock it or to stop the engine immediately. Once, the vehicle is being stolen, alert SMS will be sent to the vehicle owner for further processing. An interfacing mobile is also connected to the microcontroller, which is in turn, connected to the engine. The designed and developed system is installed in the vehicle. The developed system makes use of an embedded system based on GSM technology. This paper proposes a Driverless Intelligent Vehicle that has an onboard GPS equipped autopilot system, which is capable of driving the vehicle from one point to another without human operator and also with a theft control system for an automobile, which is being used to prevent/control the theft of a vehicle.
