Abstract

A wired and wireless vehicle communication network includes network node modules, switch modules, bridge-routing modules, and a network manager. The network manager is operable to determine a wired packet communication mode and/or a wireless packet communication mode. When the network is in the wireless packet communication mode, the network manager coordinates wireless communication of packets among the network node modules, the switch modules, and the bridge-routing modules based on individual content of the packets and wireless channel mapping. When the network is in the wired packet communication mode, the network manager coordinates wired communication of packets among the network node modules, the switch modules, and the bridge-routing modules based on the individual content of the packets and in accordance with a global vehicle network communication protocol.

First claim

What is claimed is:

1. A wireless communication network operable in an automotive vehicle comprises:
a plurality of wireless network node modules in the automotive vehicle; and
a network manager in the automotive vehicle operable to coordinate wireless communication of a plurality of packets among the plurality of wireless network node modules based on a wireless channel mapping, wherein the wireless channel mapping includes:
a permanent allocation of at least one channel of a set of channels for one or more of the plurality of packets when a source or a destination of the one or more of the plurality of packets is a safety critical automotive vehicle device;
a non-permanent allocation of at least one channel of the set of channels for the one or more of the plurality of packets when the source or the destination of the one or more of the plurality of packets is a non-safety critical automotive vehicle device; and
an allocation of the set of channels in a cellular pattern among a plurality of regions within the wireless communication network of the automotive vehicle to reduce channel interference from overlapping channel use in different ones of the plurality of regions within the wireless communication network of the automotive vehicle.

2. The wireless communication network of claim 1 , wherein the wireless channel mapping further includes:
a permanent allocation of at least one channel of the set of channels when the one or more of the plurality of packets is of a first content type, wherein the first content type includes at least vehicle safety critical content.

3. The wireless communication network of claim 2 , wherein the wireless channel mapping further includes:
a semi-permanent allocation of at least one channel of the set of channels when the one or more of the plurality of packets is of a second content type, wherein the second content type includes network data content.

4. The wireless communication network of claim 2 , wherein the wireless channel mapping further includes:
a semi-permanent allocation of at least one channel of the set of channels when the one or more of the plurality of packets is of a second content type, wherein the second content type includes non-critical vehicle operation content.

5. The wireless communication network of claim 2 , wherein the wireless channel mapping further includes:
a dynamic allocation of at least one channel of the set of channels when the one or more of the plurality of packets is of a third content type, wherein the third content type includes multimedia content.

6. The wireless communication network of claim 1 , wherein the non-permanent allocation of at least one channel of the set of channels for the one or more of the plurality of packets when the source or the destination of the one or more of the plurality of packets is the non-safety critical automotive vehicle device comprises:
a semi-permanent allocation of at least one channel of the set of channels when the source or the destination of the one or more of the plurality of packets is at least one of: a non-critical automotive vehicle operation device or the network manager; and
a dynamic allocation of at least one channel of the set of channels when the source or the destination of the one or more of the plurality of packets includes at least one of: a multimedia automotive processing device or a non-critical sensor automotive device.

7. The wireless communication network of claim 1 , further comprising a wireless network interface configured to bridge communications to a wireless data network external to the automotive vehicle.

8. An automotive vehicle, comprises:
a plurality of wireless network node modules in the automotive vehicle operable to transmit and receive a plurality of packets using wireless channel mapping, wherein the wireless channel mapping includes:
a permanent allocation of a channel when at least a source or a destination of a packet is a safety critical device in the automotive vehicle;
a non-permanent allocation of the channel when at least the source or the destination of the packet is a non-safety critical device in the automotive vehicle; and
an allocation of channels within a frequency band in a cellular pattern among a plurality of regions within the automotive vehicle to reduce channel interference from overlapping channel use in different ones of the plurality of regions within the automotive vehicle.

9. The automotive vehicle of claim 8 , wherein the non-permanent allocation of the channel when at least the source or the destination of the packet is a non-safety critical device in the automotive vehicle comprises:
a dynamic allocation of the channel when the source or the destination is at least one of: a multimedia processing device or a non-critical sensor device.

10. The automotive vehicle of claim 8 , further comprising a wireless network interface configured to bridge communications to a wireless data network external to the automotive vehicle.

11. The automotive vehicle of claim 8 , wherein the wireless channel mapping comprises:
allocating the channel from a set of channels within a frequency band for at least a portion of conveyance of the packet.

12. The automotive vehicle of claim 11 , wherein the wireless channel mapping comprises:
allocating a second channel of the set of channels within the frequency band for a second portion of conveyance of the packet from the source to the destination.

13. The automotive vehicle of claim 8 , further comprising:
a network manager, wherein the network manager is operable to coordinate wireless communication of the plurality of packets among the plurality of wireless network node modules in accordance with a global vehicle network communication protocol.

14. The automotive vehicle of claim 13 , wherein the global vehicle network communication protocol comprises at least one of: information relating to a network fabric formatting of the packets; information relating to packet transmission prioritization schemes; information relating to network management processing; or information relating to vehicle network operation parameters.

15. The automotive vehicle of claim 8 , wherein the wireless channel mapping further comprises at least one of:
a permanent allocation of the channel when the packet is of a first content type, wherein the first content type includes at least a vehicle safety critical content;
a semi-permanent allocation of the channel when the packet is of a second content type, wherein the second content type includes at least one of: network data content or non-critical vehicle operation content; or
a dynamic allocation of the channel when the packet is of a third content type, wherein the third content type includes at least one of: non-critical vehicle operation content or multimedia content.

16. A vehicle network module comprises:
a wireless network interface in an automotive vehicle; and a network manager in the automotive vehicle operable to:
authorize the wireless network interface to wirelessly communicate a packet with one or more other wireless network interfaces in the automotive vehicle using wireless channel mapping, wherein the wireless channel mapping comprises:
a permanent allocation of a channel when a source or a destination of the packet is a safety critical automotive vehicle device;
a non-permanent allocation of the channel when the source or the destination of the packet is a non-safety critical automotive vehicle device; and
an allocation of a channel from a set of channels within a frequency band to reduce channel interference from overl
