Design and Development of OBD-II Compliant Driver Information System

Abstract

Background/Objectives: On-Board Diagnostics, or OBD, in a vehicle connection, is a term alluding to a vehicle's logical toward oneself and reporting ability. OBD systems give the vehicle proprietor or a repair expert access to condition of origin data for different vehicle sub-systems. Methods/Statistical Analysis: The driver data framework (DIS) is connected in a vehicle through OBD-II connector. Initially, live information undertaking that gives real time gauges reading. The live information is constrained to show an ambient temperature, Throttle position, Intake manifold absolute pressure, MAF air flow rate, calculated engine load value, intake air temperature, Engine coolant temperature, RPM and vehicle speed (km/h). Second assignment is DTC filtering framework that offers diagnostic trouble codes. Findings: The point of this venture is to get a completely useful Programmable System on Chip (PSoC) platform working with observing live data monitoring and DTCs corresponds with all present day vehicles. Correspondence to and from the ECU will be done utilizing the On-Board Diagnostics two (OBD-II) standard. The correspondence with the ECU must be taken care of utilizing a surveying sort system as information programmed overhauling of information from the ECU isn't possible sporadically. Rather a cyclic process or string will need to run ceaselessly to do a question to the ECU took after by the perusing of the answer. The product will need to work with the returned hexadecimal information in a manner that gives the client or driver valuable information. Conclusion/Improvements: Driver Information System (DIS) helps effective and efficient use of vehicles and can assist a relatively inexperienced drive to shift to proper gears or proper acceleration according to the load on the engine and there by achieve better fuel economy and better emission performance.
