Than the 2021 RAV4 Hybrid, meaning a different set of CAN signals are produced. If you want to read the data from these vehicles, you need to have the ability to have different DBC files for each. This leads to a lot of complexity. DIMO has over 10,000 types of cars in our database (accounting for different years and trims). Most cars have 70+ ECUs and sensors, meaning there is a huge number of DBC files to figure out how to read if we want to maximize the data we get from each car. So how do we tackle this huge problem? Open-Source DBC Decoding Luckily, people have been hard at work decoding DBC files around the world. Some of those folks are already a part of the DIMO community. Generally, these are car hackers who want to understand their own vehicle and believe that information should be free and open: they’re helping push back against the monopoly of car data between dealerships and car makers. The most prominent project is OpenDBC, started by comma.ai to facilitate DBC decoding for their after-market self-driving system (which is super cool). They have helped decode 100s of cars and made that DBC files available to others. Other companies and projects have made it their business to decode vehicles. DIMO is already supporting DBC decoding efforts and will begin supporting others in a more prominent way via bounties and more. If you’re interested in helping to decode DBC files, please contact hello@dimo.zone and we can help integrate you with the existing community. What does this all mean for DIMO? Decoding DBCs is a task that requires the person or team to go one signal at a time. Each task requires physically being in the car, executing actions and analyzing data. All told it can
