Dual-network for fault tolerance

Abstract:

Embodiments herein relate to a vehicle, including a first plurality of devices associated with a first vehicle function and a second plurality of devices associated with a second vehicle function. The first communication network communicatively couples each of the first plurality of devices to each other, communicatively couples each of the second plurality of devices to each other, and communicatively couple the first plurality of devices to the second plurality of devices. Further, a second communication network communicatively couples less than all of the first plurality of devices to less than all of the second plurality of devices, where the second communication network transmits messages determined to be critical from a first device of the first plurality of devices to a first device of the second plurality of devices.
