Driving the Future

A CAN bus, the common intra-vehicle network standard, has been used for over three decades. However, its weight, maintenance costs, and installation complexity increase with more ECUs, especially in AVs. This book aims to replace wired CAN with wireless CAN. Proposed solutions include designing an AV model with external and internal ECUs using CANoe/MATLAB simulation. Modifying ECU architecture for wireless communication, implementing a hidden communication environment with CCK modulation, and addressing jamming signals using dual channels. Testing using MATLAB and OPNET shows stable BER and packet loss, with robust CCK modification and challenges in signal interception. Results indicate successful integration of internal and external ECUs with IEEE 802.11b, and using 100BaseT Fast Ethernet for high bandwidth LiDAR data and delay requirements.
