CarTwin—Development of a Digital Twin for a Real-World In-Vehicle CAN Network

Digital twins are used to replicate the behavior of physical systems, and in-vehicle networks can greatly benefit from this technology. This is mainly because circulate large amounts data coming various sources such as wired, or in some cases even wireless, sensors that fused by actuators responsible for safety-critical tasks require careful testing. In work, we build a laboratory network mimics real vehicle regards wire length, number stubs devices connected it. The Controller Area Network (CAN), which still most popular communication bus inside cars, layer. Using models defined MATLAB subsystems, e.g., Anti-lock Braking System (ABS), Powertrain Electric Power-Steering, deployed on automotive-grade microcontrollers, evaluate digital twin providing realistic inputs recording reproducing traffic. experimental results showed good correlation between output implemented collected an actual car.
