Dual-network for fault tolerance

The vehicle of claim 2, wherein the first device of the first plurality of devices includes a first communication interface coupled to the first communication network and a second communication interface coupled to the second communication network, and wherein the first device of the second plurality of devices includes a first communication interface coupled to the first communication network and a second communication interface coupled to the second communication network.

The vehicle of claim 3, wherein the second communication network is a communication pathway directly connecting the second communication interface of the first device of the first plurality of devices to the second communication interface of the first device of the second plurality of devices.

The vehicle of claim 4, wherein communication via the first communication network is in accordance with an Ethernet protocol and communication via the second communication network is in accordance with a controller area network protocol.

A non-transitory information storage media having stored thereon one or more instructions, that when executed by one or more processors, cause a processor to perform a method, the method comprising:

• determining if a communication message originating from a device associated with a first vehicle function is to be routed over a first communication network or a second communication network, wherein the first communication network communicatively couples each of a first plurality of devices to each other, communicatively couples each of a second plurality of devices to each other, and communicatively couples the first plurality of devices to the second plurality of devices, and the second communication network communicatively coupling less than all of the first plurality of devices to less than all of the second plurality of devices;
• and
• routing the communication message over the second communication network when the communication message is determined to be critical.
