Abstract

An example system includes a vehicle having an Ethernet based network and a controller area network (CAN) based network; a CAN vehicle control device disposed onboard the vehicle and structured to control operation of a component of the vehicle; an Ethernet vehicle control device disposed onboard the vehicle and structured to electrically communicate with the CAN vehicle control device; an Ethernet switch disposed onboard the vehicle and having a plurality of physical ports connected to the Ethernet based network; a CAN gateway disposed onboard the vehicle and connected to the CAN based network and the Ethernet switch; and a network convergence circuit defined at least in part by the Ethernet switch and/or the CAN gateway, and structured to facilitate electronic communications between the Ethernet vehicle control device and the CAN vehicle control device.

First claim

What is claimed is:

1. A system comprising:
a vehicle having an Ethernet based network and a controller area network (CAN) based network;
a CAN vehicle control device disposed onboard the vehicle, connected to the CAN based network, and structured to control operation of a component of the vehicle;
an Ethernet vehicle control device disposed onboard the vehicle, connected to the Ethernet based network, and structured to electrically communicate with the CAN vehicle control device;
an Ethernet switch disposed onboard the vehicle and having a plurality of physical ports connected to the Ethernet based network, at least one physical port of the plurality forming part of a physical network path between the Ethernet switch and the Ethernet vehicle control device;
a CAN gateway disposed onboard the vehicle and connected to the CAN based network and the Ethernet switch; and
a network convergence circuit defined at least in part by the Ethernet switch and/or the CAN gateway, and structured to facilitate electronic communications between the Ethernet vehicle control device and the CAN vehicle control device by translating and relaying data messages between the Ethernet based network and the CAN based network;
wherein:
the network convergence circuit is selectively configurable via a configuration command value transmitted over the Ethernet based network from a service device external to the vehicle; and
the configuration command value is structured to modify the network convergence circuit via selectively configuring which of one or more portions of the network convergence circuit are defined by the Ethernet switch and/or the CAN gateway.

2. The system of claim 1 , wherein:
a first physical port of the plurality selectively mirrors a second physical port of the plurality in response to the configuration command value.

3. An apparatus comprising:
a first network interface circuit structured to interpret a first Ethernet data set and to transmit a second Ethernet data set;
a second network interface circuit structured to transmit a first controller area network (CAN) data set and to interpret a second CAN data set;
a translation circuit structured to:
determine a first message value from the first Ethernet data set and to encapsulate the first message value in the CAN data set; and
determine a second message value from the second CAN data set and to encapsulate the second message value in the second Ethernet data set; and

a configuration circuit;
wherein:
the first network interface circuit, the translation circuit, and the second network interface circuit are defined by an Ethernet switch and/or a CAN gateway both structured to be incorporated into a vehicle; and
the configuration circuit is defined by the Ethernet switch and/or the CAN gateway and structured to:
modify the first network interface circuit, the translation circuit, and/or the second network interface circuit in response to a configuration command value; and
selectively configure which of one or more portions of the first network interface circuit, the translation circuit, and/or the second network interface circuit are defined by the Ethernet switch and/or the CAN gateway.

4. The apparatus of claim 3 , wherein the first network interface circuit is defined by the Ethernet switch and the second network interface circuit is defined by the CAN gateway.

5. The apparatus of claim 4 , wherein the translation circuit is defined by the CAN gateway.

6. The apparatus of claim 4 , wherein the translation circuit is defined by the Ethernet switch.
