Design and Development of Flexible On-Board Diagnostics and Mobile Communication for Internet of Vehicles

Internet of Vehicles is an upcoming technology. In our project, we are taking a step towards this vision by developing a system that could be easily connected to the Electronic Control Unit of vehicles using Raspberry Pi, Arduino, and Wi-Fi, to connect the OBD of any vehicle with a Smartphone. The proposed system establishes a connection with OBD of a vehicle and provides vehicular connectivity with Smartphones using internet for the already existing vehicles that don't have an inbuilt vehicular connection, plus add additional sensor units which are not present, making it easy to monitor all the systems in the vehicle. Most vehicles that are on roads don't have this technology and this is mostly found in expensive cars. Using the proposed system, such vehicular connection system can be installed separately at a cheaper expense in all vehicles. Through this, the status of the vehicle is diagnosed by the OBD system and the report is transferred using Wi-Fi to the car owner's smartphone. Using the system, additional sensors can be added to a vehicle to upgrade its functionality, which the system supports. Additionally, driver assist functions are introduced, helping the driver during travel.
