On Board Diagnostics (OBD) Scan Tool to Diagnose Emission Control System

Climate change has become very important issue the world is facing today. To control impact of climate change and improve quality of life, one of the key factor targeted is vehicular emissions. To control emissions very stringent emission norms are introduced by various government agencies across the world. This called for increased use for electronics in the engines and vehicles. This complicates the matter at service and manufacturers. The engine computer (Electronic Control Unit) with international protocol like OBD is used to control electronic parameters in engines. This review paper describes emission compliance requirement with brief introduction of the OBD system along with scan tool to diagnose the system

SMART sensor network: with Bluetooth low energy and CAN-BUS

This paper proposes a system to monitor, through the internet, the data of a logistics distribution truck. For this, it was implemented a reliable and flexible wireless sensor network with low energy consumption. The technology used for the radio system was Bluetooth Low Energy (BLE). Each node in the network contains one type of sensor. The sensors information together with GPS and On-Board Diagnostics (OBD) data collected by the central unit, and later transmitted to the cloud by GSM or Wi-Fi.info:eu-repo/semantics/acceptedVersio

Pemanfaatan Fitur On Board Diagnostics (OBD-II) Pada Kendaraan Roda Empat

Kecelakaan lalu lintas adalah suatu peristiwa di jalan yang tidak diduga dan tidak disengaja melibatkan kendaraan dengan atau tanpa pengguna jalan lain yang mengakibatkan korban manusia dan/atau kerugian harta benda. Pemerintah telah membuat peraturan mengenai investigasi kecelakaan dan penanganan pertama pada suatu kecelakaan. Purwarupa pada tugas akhir ini adalah sistem yang dapat merekam dan mengklasifikasi jika terjadi kecelakaan. Perekaman kondisi kendaraan memanfaatkan fitur OBD-II dengan parameter berupa kecepatan kendaraan dan temperatur mesin. Pengklasifikasian kecelakaan memanfaatkan kecepatan kendaraan, kondisi airbag, dan nilai Gs akselerometer. Fitur OBD-II dapat dimanfaatkan purwarupa dalam pengujian perekaman data pada mobil Toyota Yaris. Akselerometer ADXL345 dan DTC dapat dimanfaatkan untuk klasifikasi kecelakaan, SIM900 dapat dimanfaatkan untuk mengirim data pada server dan mengirim notifikasi berupa SMS jika terjadi kecelakaan kepada pihak berwenang

Real-world performance of catalytic converters

This paper investigates experimentally the performance of a three-way catalytic (TWC) converter for real-world passenger car driving in the United Kingdom. A systematic approach is followed for the analysis using a Euro-IV vehicle coupled with a TWC converter. The analysis shows that the real-world performance of TWC converters is significantly different from the performance established on legislative test cycles. It is identified that a light-duty passenger vehicle certified for Euro-IV emissions reaches the gross polluting threshold limits during real-world driving conditions. This result is shown to have implications for overall emission levels and the use of remote emissions sensing and on-board diagnostics (OBD) systems

Managing nonuniformities and uncertainties in vehicle-oriented sensor data over next generation networks

Detailed and accurate vehicle-oriented sensor data is considered fundamental for efficient vehicle-to-everything V2X communication applications, especially in the upcoming highly heterogeneous, brisk and agile 5G networking era. Information retrieval, transfer and manipulation in real-time offers a small margin for erratic behavior, regardless of its root cause. This paper presents a method for managing nonuniformities and uncertainties found on datasets, based on an elaborate Matrix Completion technique, with superior performance in three distinct cases of vehicle-related sensor data, collected under real driving conditions. Our approach appears capable of handling sensing and communication irregularities, minimizing at the same time the storage and transmission requirements of Multi-access Edge Computing applications

On the road with RTLola : Testing real driving emissions on your phone

This paper is about shipping runtime verification to the masses. It presents the crucial technology enabling everyday car owners to monitor the behaviour of their cars in-the-wild. Concretely, we present an Android app that deploys rtlola runtime monitors for the purpose of diagnosing automotive exhaust emissions. For this, it harvests the availability of cheap Bluetooth adapters to the On-Board-Diagnostics (obd) ports, which are ubiquitous in cars nowadays. The app is a central piece in a set of tools and services we have developed for black-box analysis of automotive vehicles. We detail its use in the context of real driving emission (rde) tests and report on sample runs that helped identify violations of the regulatory framework currently valid in the European Union

Deteksi Jalan Basah Pada Kendaraan Dikombinasikan Dengan OBD-II Protocol

Di era modern saat ini, tingkat otomatisasi pada kendaraan bermotor cenderung mengalami peningkatan dari perspektif keselamatan pengemudi, karena itu deteksi permukaan jalan basah yang disebabkan oleh air atau oli menjadi lebih penting untuk informasi keselamatan terhadap pengemudi. Meskipun pengemudi dapat dengan mudah membedakan antara jalan yang kering dan basah, namun mengingat kondisi ini berguna secara langsung untuk keamanan pengemudi dalam situasi yang menuntut untuk mengembalikan kendaraan bermotor dari situasi kritis kembali menjadi kepada keadaan aman, tetapi sejauh ini sulit untuk mengukur lapisan jalan yang basah dan dampak terhadap dinamika kendaraan, oleh karena itu, dengan menggunakan sistem yang tidak banyak mengeluarkan biaya dan tidak merugikan pengguna serta sederhana dan mudah dipasang. On-board vehicle road wetness detection (deteksi jalan basah untuk kendaraan) dapat menjadi sebuah solusi untuk permasalahan tersebut. on-board vehicle road wetness detection menyajikan pendekatan baru untuk mendeteksi basah permukaan jalan dengan on-board diagnostics (OBD) II sensor board dan multi-sensor data fusion pada kendaraan. Metodologi yang digunakan untuk pembuatan tugas akhir ini adalah dengan menggunakan pengolahan data fuzzy logic, lalu percobaan di bangku uji kemudian di integrasikan kedalam kendaraan dan menganalisa metode serta studi pustaka, dimana akan digunakan sebuah kendaraan yang memiliki ECU (engine control unit) untuk dihubungkan dengan OBD II protocol sebagai objek pengujian. Kata Kunci: On-Board Diagnostics (OBD), Multi-Sensor data fusion, Engine Control Unit (ECU)

Evaluation of Eco-Driving Using Smart Mobile Devices

The methods of measuring driving behaviour and the quality of drive in road transport are important factors in data acquisition and subsequent analysis of driving. The prevalence of smart terminal devices and cost effectiveness of On-Board Diagnostics (OBD) sensor devices provide great potential and the availability of the aforementioned technologies. This study shows the possibility of using information and communication technologies (ICT) and sensor devices for measuring the effectiveness of eco-driving. The ease of implementation of ICT elements, the accuracy of collected data and their storage for later data analysis offer a number of possibilities to use. This study shows the technical solution of the system and analysis of collected data on actual driving samples. By comparing normal and eco-driving modes, the advantage of using eco-driving modes is demonstrated through reduced fuel consumption and CO2 emissions amounting to almost 23% and 31%, respectively
