Implementation of integrated OBD-II connector with external network

摘要

AbstractOrdinarily, a driver knows the current driving state of a vehicle through the On Board Diagnosis-II (OBD-II) data. Lately convenience devices related to real-time vehicle control and driving information data have been using OBD-II from the vehicle network.However, when these devices receive vehicle data rom the OBD-II network, each device receives its own information separately using its own vehicle network. If the driver changes the product and OBD-II connector to use OBD-II, the driver also changes the OBD-II connector. As a result, the driver spends useless money for the product and vehicle to use OBD-II.In this paper, we implemented integrating an OBD-II connector that uses Bluetooth, Wi-Fi, and WCDMA modules to overcome the above disadvantage.
