Next generation Telematics services demanding remote access to vehicle operational data. A challenge with vehicles utilizing complicated embedded systems is how to extract the vehicle diagnostic data, evaluate it to expose possible problems and determine how to fix any problems. This paper describes a vehicle data acquisition system by use of Embedded system places in vehicle and GPRS connectivity. Large number of data can be transmitted from the vehicle after collecting it from the ECU’s fitted in the vehicle. This system is reliable and cost effective also. Keywords — Vehicle Telematics, Embedded Syatem, GPRS 1 Introduction Now a day’s vehicles are equipped with more and more electronic gadgets. These Electronics devices plays vital role in controlling engine parameters (i.e. proper functioning of engine as well as emissions parameters), safety, comfort, navigation, entertainment and much more. Most of these devices are connected to each other for gathering information. Further these Electronic modules provide a diagnostic network interface through a In-Vehicle network protocols (such as KWP2000, LIN and CAN) to read number of parameters related to the engine and vehicle body electrical and also monitor the Diagnostic Trouble Codes (DTC’s). The DTC’s provide valuable information on the faults and also the sub system where the faults have occurred. There is need of access of the data available in vehicle for Vehicle parameters monitoring at the time of vehicle testing (when vehicle is in design stage), to monitor the vehicle to diagnostic and resolve any problem detected when vehicle is away from home place and from security point of view also. Earlier the testing vehicle (running on highway) equipped with data loggers and other test equipments were able to give collected data only when that will come back to office. And hence there were chance of data loss. Hence repeated testing was required in some cases. To solve all these problems we have designed a system by help of an embedded system along with GPRS modem and vehicle electrical and electronics systems to give cost effective solution to collect correct and large number of data. Hence test engineer can access the Vehicle Data by using GPRS Embedded Web server fitted in the vehicle. Using this technique the vehicle test engineers / owners are able to access vehicle operational and diagnostic data remotely as well as control certain parameters / systems from any place in the world, because this data is available on internet. 2. Overview and Related Work Basically Telemetics [1] has meant the blending of telecommunications and informatics. Vehicle Telematics deals with exchange of data from vehicle collected from vehicle networks and used for vehicle tracking, vehicle monitoring, and toll collection and for number of things. Phalake M.
