CGW is the central communication node, acts as a router (for in-vehicle communication and through the CCU to the outside) and is the gate for all data coming into the vehicle. It supports various bus systems (Ethernet, CAN, LIN).
Centralized communication node
Allows data exchange between different domains and control units within vehicles
Handles the fast growing in-vehicle data rate and also the communication to the outer world
Protects the in-vehicle network against unauthorized access with security concepts like e.g. Firewall, Hardware Security Module (HSM) or Intrusion Detection System (IDS)
The central communication node “Gateway” is the home for the growing number of cross domain functions and IoT services around the vehicle
