System Operation
The Ethernet communication network enables data transfer speeds of 100Mbps to 1Gbps to support the on vehicle applications that require high data transfer rates such as over-the-air updates, driver assistance systems (video data, radar data, ultrasonic data), multimedia and entertainment systems and connectivity to external devices and services. The GWM is the primary module within the Ethernet communication network and manages the distribution of data to the other connected modules on the network. Data from external sources (cloud-based data) is received by the TCU and transferred over the Ethernet communication network to the GWM where it is distributed to the other modules connected to the Ethernet communication network and the various vehicle communication networks. The modules connected to the Ethernet communication network are dependent on the vehicle configuration.
