1 International Journal of Advanced Research in Computer Engineering & Technology (IJARCET). Volume 3 Issue 3, March 2014. ON-BOARD DIAGNOSTIC SYSTEM FOR VEHICLES . , , , ABSTRACT LITERATURE SURVEY. ON-BOARD DIAGNOSTIC [1] From Parking vehicle systems play an important role in the positioning SYSTEM based on ZigBee , Jia current generation of cars and will play an Huiqin1 Xi'an Shiyou University, China, increasingly important role in the next it is observed that ZigBee is a new kind of future. This paper proposes the short distance, low power consumption, development of ON-BOARD low cost, low rate and low complexity DIAGNOSTIC SYSTEM for VEHICLES wireless network technology. It takes all using wireless sensor network. This OBD advantages of In this paper SYSTEM consists of Arduino board which ,we use ZigBee technology to construct a has an ATMEGA microcontroller that acts wireless communication network, setting a as a processing unit where the program is full function ZigBee module as a written using ARDUINO software, coordinator in the proper place of the sensors, LCD and keypad as user interface.

2 Parking lot, it communicate directly with The vehicle parameters such as fuel level, the host computer. Install several ZigBee temperature, voltage are sensed and those routers according to the distance need, and results are viewed from LCD display. record their position information. Because Initially, the sensors are installed at this SYSTEM is directed to card users, so different parts of the vehicle to sense each vehicle is required to install a ZigBee various vehicle parameters. For wireless module. data transmission, zigbee is used. [2] From Generating ON-BOARD KEY WORDS: Arduino,OBD, Sensor, diagnostics of dynamic automotive Zigbee. systems based on qualitative models . Centro Ricerche Fiat, Strada Torino 50;. Dip.

3 Informatica, University di Torino, it is understood that offboard diagnosis can INTRODUCTION take full advantage of the model-based approach, ON-BOARD diagnosis requires ON-BOARD DIAGNOSTIC some further considerations and taking systems play a very important role in the into account some important practical performance of VEHICLES . Usually it takes constraints. First of all, in the ON-BOARD more time to diagnose a problem in case the DIAGNOSTIC SYSTEM must react vehicle than to rectify it. So these systems promptly to anomalies and must run fast in not only diagnose the faults but also save order to interpret the anomalies and, which us a lot of time. Parameters observed and is most important, in order to take an diagnosed by OBD SYSTEM are used by the appropriate recovery action.

4 This means Electronic Control Unit (ECU) of vehicle also that the ON-BOARD diagnostics should which in turn controls the engine's main be focused only on performing recovery operation (like spark timing control, air actions, rather than on the actual isolation fuel mixture, fuel injectors spraying period of the fault(s) . However, keeping track of etc.).Combination of these two systems more detailed information about the ensures safety and efficient vehicle fault(s) that occurred can be extremely operation. important, as it is a valuable information to ISSN: 2278 1323 All Rights Reserved 2014 IJARCET 860.

5 Be passed to the DIAGNOSTIC SYSTEM that will VEHICLES generally safer. This paper will be used in the workshop to actually locate provide details about a number of events and identify the fault . Moreover, only a and probable scenarios to demonstrate the few measurements can be available added value of having access to the onboard and the possibility of performing vehicle's communication network. tests/probes is very limited . [5] From A Study on Remote [3] From ZigBee-based Vehicle On-Line DIAGNOSTIC SYSTEM for Access Control SYSTEM by Rong Zhou, VEHICLES by Integrating the Technology Chunyue Zhao, Lili Fu, Ao Chen and of OBD, GPS, and 3G by Jyong Lin, Meiqian Ye College of Information & Shih-Chang Chen, Yu-Tsen Shih, and Shi- Electronic Engineering Zhejiang Huang Chen it is cleared When the OBD.

6 Gongshang University Hangzhou, China SYSTEM detects a malfunction, OBD. following is understood. when a vehicle regulations require the Electronic Control assess to the entrance, the transmitter Unit (ECU) of the vehicle to save a installed in the car sends related standardized DIAGNOSTIC Trouble Code information, through the radio transmitter (DTC) about the information of module in CC2430 chip, to the receiver malfunction in the memory. An OBD Scan which is set in the access control office. Tool for the servicemen can access the After successfully received the vehicle's DTC from the ECU quickly and accurately information, the receiver passes the data to to confirm the malfunctioning microcontroller to decode them. The characteristics and location in accordance control SYSTEM will receive this with the prompts of DTC that shortens the information and store it in the database.

7 Service time largely. Moreover, currently The manager can query all the information the number of item for the real-time in database, including license plate driving status that OBD can monitor is as number, driver number and so on. high as up to 80 items [4] From Vehicle ON-BOARD diagnostics Added Values Technical EXISTING SYSTEM . Paper by H tu, S. Plante we understood that Today's VEHICLES have In 1996, OBD-II SYSTEM was more and more electronics, and this leads developed by SAE ( of to a greater wealth of information available automotive engineers), EPA (Environment on a vehicle's communication network. protection agency ) and CARB. This paper will address the added value of (California air resources board ). Majority having access to this information.

8 Whether of automobiles that were introduced in you are the development engineer, the after 1996 had this SYSTEM . This dealership mechanic or the end-user, the SYSTEM has become a standard for all information available to the different VEHICLES . These systems monitor different individuals has become indispensable. parameters of vehicle and store Rapid diagnostics of events and faults, information in memory but don't have any automatic correctional interaction of interface for user. Whenever a fault arises vehicle equipment to compensate failures, in the vehicle, the SYSTEM senses it and as well as preventive maintenance alerts of notifies the user of warnings using a specific vehicle components are all actions malfunction indication light (MIL).

9 That are helping the various individuals Flashing of MIL in different sequences throughout the vehicle's existence. These tells user nature of problem ; This, actions are helping to save time, increase however, is not an effective way of diagnostics accuracy and make the warning indication as user cannot tell ISSN: 2278 1323 All Rights Reserved 2014 IJARCET 861.
