Build Automotive Gateways with Ease
Don Hatfield explores central automotive gateways, explaining how multi-bus routing, translation, and security firewalls protect in-vehicle networks.
Summary
The Evolution of In-Vehicle Network Topologies
Modern vehicles integrate dozens of Electronic Control Units (ECUs) communicating across divergent protocols—such as CAN, CAN FD, LIN, FlexRay, and Automotive Ethernet.
The Central Role of Automotive Gateways
Don Hatfield explains how automotive central gateways act as the nervous system, routing messages, translating frame formats, and isolating security domains.
Designing Secure and Flexible Gateway Hardware
Hatfield demonstrates building prototype automotive gateways using open hardware and modular embedded development platforms.
Implementing Diagnostic Firewalling and Filtering
The presentation details implementing stateful CAN frame filtering and rate limiting to prevent compromised infotainment units from injecting safety-critical commands.
