Automotive Electronic safety for Intelligent Transportation System

The use of tracking a vehicle become critical in many applications including personal vehicle security, public transportation systems, passengers safety, fleet management and others. Also, it is expected to rapid increase of vehicles on road globally. Therefore, the development of vehicle tracking system as per Automotive Industry Standard (AIS-140) using the Global Positioning System (GPS), Indian Regional Navigation Satellite System (IRNSS) and Global System for Mobile Communications/General Packet Radio Services (GSM/GPRS) modem is undertaken with the aim of enabling users and government bodies to locate the vehicles to monitor and control in an ease and efficient manner. The user also can track, monitor and control their vehicle remotely through mobile network. This paper is intended for the development of the vehicle tracking system's hardware prototype as per AIS-140. Specifically, this paper proposes the architecture for protection of power input against the automotive electrical transients as per ISO 7637-2 (2004). It includes under voltage cut off and pi filter to make the system electromagnetic compatible with vehicle electronics sub system.
