Next Generation In-vehicle Networking (IVN): Enabling Connected and Autonomous Driving
Modern vehicles are increasingly becoming more connected and automated with advanced driver assistance systems. However, the traditional in-vehicle networks are proving to be inadequate to support the data and communication requirements of next generation connected and autonomous vehicles. Next generation IVN standards are being developed to overcome the limitations of current networks and enable new autonomous driving technologies. Introduction to Current IVN Technologies Currently, most vehicles rely on Controller Area Network (CAN) bus as the main in-vehicle network for connecting electronic control units (ECUs) and transmitting data. CAN bus has served vehicle networking needs well since its introduction but it has some drawbacks. CAN bus has a limited data transmission rate of only around 125 Kbps to 1 Mbps which is insufficient for handling vast amounts of sensor and system status data in connected and autonomous vehicles. It also does not support advanced features like pri
