Development of an On-Board Diagnostic (OBD) kit for troubleshooting of compliant vehicles

Driving Big Data: A First Look at Driving Behavior via a Large-Scale Private Car Dataset

“…As shown in Fig. 1(b), each car is installed with a lightweight and lowcost On-board Diagnostics (OBD) monitor which is compatible with ISO 14230 (KWP2000) and Society of Automobile Engineers (SAE) protocols [9]. OBD monitors are in the charge of recording the status of vehicle subsystems, such as the engine, braking system, cooling system, and the electronic control module.…”

“…These distributions also suggest that a private car has more than 17% probability to make four trips per day, and a trip has more than 25% probability to last 20-30 minutes and 33% probability to travel 10 Kilometers during the trip. The average fuel efficiency vehicle trajectory, the human trajectory [3][4][5][6][7][8][9][10][11][12][13][14][15], in which the trajectory data were ile phone and cellular communication s in [13] discovered human mobility patl and individual levels, and a parametered to detect hotspots. Trajectory data for llected by a large Chinese 4G service days (October 10th 2013 to October sed in their experiments.…”

“…The paper [15] studied individual ith the mobile phone trace data and ection data in the Boston Metropolitan vehicle-related data used in most of cted from public vehicles. For instance, s or taxies was used in [8], [9], [10], e all know, there are notable differences rs and buses or taxis in some aspects. ld a large proportion in the total amount rban road network, especially in China e cars are used with a clear purpose tly reflect the personal travel demand.…”

Mobil Cihaz Temelli Araç Hız Uyarı Sistemi

“…OBD-II portuna uyumlu fiziksel bir dönüştürücü cihaz ile CAN veri yolu üzerinden okunan veriler anlamlı hale getirilir [6]. OBD-II standardını destekleyen OBD diagnostik cihazları farklı araçlara uyum sağlar nitelikte geliştirilmektedir [7]. Araç ile haberleşme ECU verilerinin ELM327 OBD-II cihazı üzerinden bilgisayar ya da mobil bir cihazda görüntülenmesi ile sağlanır.…”

“…Araç ile haberleşme ECU verilerinin ELM327 OBD-II cihazı üzerinden bilgisayar ya da mobil bir cihazda görüntülenmesi ile sağlanır. OBD-II protokollerini dönüştürmek için kullanılan ELM327 OBD-II cihazı RS232 seri portu ve OBD-II portu arasında köprü görevi görür [4,7]. İlerleyen süreçte OBD-II diagnostik cihazları kablosuz olarak üretilmiş ve CAN veri yoluna mobil cihaz ya da tablet gibi taşınabilir cihazlar ile erişim sağlanmıştır.…”
