Autonomously Vehicle Network PIDs Parsing to Support Threat Monitoring and Early Warning Research

Abstract

The CAN Bus Messages are mostly customized on various types of vehicles. A PID-CAN-Bus-Message-Pairs parser has been designed to analyze those customized CAN Bus message stream from vehicle network. It is composed of a downstream module and a upstream module. The downstream module works for vehicle dynamic behavior fusion and real-time CAN Bus message acquisition. The upstream module gets fused vehicle dynamic behavior and real-time CAN Bus messages from downlink module to autonomously parse out the parameter identify codes which are subsequently stored to serve as the basis for autonomous driving and vehicle network information security protection research.
