Sending CAN Flexible Data-Rate Frames in an Automatic Manner to Improve Vehicle Diagnose Processes

This paper provides an algorithm for the Controller Area Network (CAN) protocol, which enables transmission of CAN single frames and CAN flexible data-rate frames in an automatic manner. The automotive industry is of key importance nowadays and, in this context, our research focuses on autonomous/ automatic diagnosis and predictive maintenance techniques, which can also be easily extended to other important areas such as mechanical engineering, robotics, avionics, healthcare and so on. Our study shows improvements of up to 14% for validating and interpreting the data with respect to the response time of the ECU, which is not negligible for real-life and industrial applications, where time efficiency in detecting malfunctions is a sensitive issue.
