Abstract: This study presents a design model for position based driver assistance systems to locate the position of the vehicles using GPS-GPRS based vehicle tracking system. The GPS tracking system of smart phone can give assistance to the driver while travelling. The GPRS technology is used to send the position of the vehicle as a SMS to the owner of the vehicle. It is used to provide security to the vehicle and driver, so, there is no needed emergency at the place in proposed method. This study focuses on tracking the position of the vehicle and sends SMS to the destination/registered mobile number through wireless technology. This system is used to provide GPS and GPRS modules interfaced with the beagle board into the vehicle. The embedded operating system angstrom is used to implement the proposed system. The processor used in the beagle board for development of device drivers of GPS and GPRS is OMAP 3530 processor. Standard Linux kernel and open CV package are used to interface GPS and GPRS modules to the driver assistance system.
