CAN Data Transfer from Vehicle to Cloud via Smartphone

Smartphones have evolved into multipurpose handheld devices and have exceeded their limits beyond communication. Apart from communication, these devices have been utilized for mobile payment, cloud-based services, artificial intelligence, Internet of Things (IoT) applications, and more. In this study, an Arduino-based system has been developed to receive commercial heavy-duty vehicle data in accordance with the SAE J1939 standard through the On Board Diagnosis II (OBD-II) connection. In addition, a smartphone application supported by graphical interface has been created to transmit processed data to the cloud. The designed system has been tested and verified by using data from an internal combustion engine passenger bus. The reliable transfer of selected data has been realized in both the smartphone and cloud environments. This study has offered a cost-effective solution for transmitting J1939 standardized vehicle data to a remote operator via a smartphone based on verified successful applications. Moreover, the created system will be a good significant resource for comparison to future applications.
