The Global Positioning System (GPS) is a space-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a
2. Control area network (CAN) and Intelligent vehicle: Intelligent vehicles are an application in which the words “intelligent autonomous systems” represent not only an important research topic but also a strategic solution to the mobility problems that may arise in the coming years. Automotive Electronics sector is now a day's becoming more in demand due to its increasing technology. Most of luxurious cars consist of automatic controls for different parameters present in the car surrounding. As more and more applications are available of on-vehicle information system, the connection between the vehicle bus network and information system is becoming a trend. Basically in automobile industries CAN protocol is used for communication. The proposed system presents the development and implementation of a digital driving system for a semi-autonomous vehicle to improve the driver-vehicle interface and can provide technological development for future applications in vehicle's information system. The system is able to monitor Road lane violation, Drowsiness and Alcohol with the help of sensors and webcam which can minimize road accidents. System contains controller block designed using ARM, alcohol and Eye-blink sensors, CAN controller, Webcam, GPS and GSM modules.
