Team Status Report 5/1/21

This week our team continued working on the three subsystems – OBDII signal detection, OBDII data analysis, and web application data display. In the OBDII detection area, we found more data points to gather to improve our safe-driving analysis. Specifically, we started measuring a number of signals that detect internal problems with the vehicle’s mechanical and electrical systems that are not obviously apparent to the user. We realized that even though vehicles often notify the driver when there is a system error through the dashboard lights, it is important to track that data so the user knows not only what the problem is, but also when the problem started. In the data analysis section, we optimized the use of API calls, making sure they are only used in locations we have not driven before. This results in a faster, less expensive final product. Finally, we have improved the web interface by adding a page that displays the status of each infraction our analysis measures. We made sure to keep it simple so the user can quickly understand if they are making an infraction and in which category. We did this using binary light displays for each infraction – either the user is making the infraction or they are not. This is important because it gives the user the option to view their mistakes in real-time and correct them, instead of only knowing after the fact when the drive is over.
