In-Depth Information
The communications networks serving the full vehicle will be of different
classes and share data via gateways. For example, apart from the powertrain,
chassis, and energy system functions illustrated in Figure 4.49, there would be
additional networks for safety and mobility, body control and infotainment as
shown in Figure 4.50, and perhaps others interconnected via gateways.

Figure 4.50 Multiple layer in-vehicle architecture
In Figure 4.50, the power and data architecture is shown with class A/B network
for body and energy management and a class C network for powertrain and hybrid
system control as well as safety and mobility plus infotainment. This high speed
network can be upgraded to include a separate, higher speed, dedicated network to
serve the infotainment functions as these become more pervasive in the automobile.
