Abstract

Mesh node modules are associated with vehicles and companion nodes can dynamically form a mesh network which uploads location information of the nodes and in some cases additional information, e.g., road condition or proximity to objects.

First claim

1 . Display device, comprising:
at least one computer memory that is not a transitory signal and that comprises instructions executable by at least one processor to: present on a display user interface (UI), the UI indicating a location of the device on which the UI is presented, along with locations of plural vehicles in a wireless mesh network that includes a vehicle in which the UI is presented, the locations of the other vehicles being received through the mesh network.

2 . The device of claim 1 , wherein the UI presents arrows whose magnitudes and directions are defined by headings and speeds of respective vehicles as reported via the mesh network.

3 . The device of claim 1 , wherein the UI presents an alpha-numeric indication of a speed of a vehicle other than the vehicle in which the UI is presented.

4 . The device of claim 1 , wherein the UI includes an alpha-numeric indication of a type of a vehicle reporting via the mesh network.

5 . The device of claim 1 , wherein the UI presents icons unique to vehicle types based on type information reported b the vehicles through the mesh network.

6 . The device of claim 1 , wherein the UI presents an alpha numeric indication of a vehicle having a speed satisfying a threshold.

7 . Display device, comprising:
at least one computer readable storage medium bearing instructions executable by a processor; and at least one processor configured for accessing the computer readable storage medium to execute the instructions to configure the processor to: present on a display a user interface (UI) including one or more filter selectors selectable to filter traffic/road reports uploaded from vehicle ad hoc networks (VANETs) and presented on the UI.

8 . The device of claim 7 , wherein the UI indicates a location of the device on which the UI is presented, along with locations of plural vehicles in a wireless mesh network that includes a vehicle in which the UI is presented, the locations of the other vehicles being received through the mesh network.

9 . The device of claim 7 , wherein the UI presents arrows whose magnitudes and directions are defined by headings and speeds of respective vehicles as reported via the mesh network.

10 . The device of claim 7 , wherein the UI presents an alpha-numeric indication of a speed of a vehicle other than the vehicle in which the UI is presented.

11 . The device of claim 7 , wherein the UI includes an alpha-numeric indication of a type of a vehicle reporting via the mesh network.

12 . The device of claim 7 , wherein the UI presents icons unique to vehicle types based on type information reported by the vehicles through the mesh network.

13 . The device of claim 7 , wherein the UI presents an alpha numeric indication of a vehicle having a speed satisfying a threshold.

14 . The device of claim 7 , wherein the filter selectors include a “local” selector which when selected causes information to be presented on the display showing information only within a predetermined distance of the display, a “state” selector which when selected causes information to he presented on the display showing information only for an entire state in which the display is located, and a “national” selector which when selected causes information to be presented on the display showing information only for an entire nation in which the display is located.

15 . The device of claim 7 , wherein the UI presents indications based on information reported by a VANET indicating current road condition.

16 . Method comprising:
automatically establishing a vehicle ad hoc network (VANET) among node modules of adjacent vehicles such that as vehicle travels it dynamically enters and leaves mesh networks formed by its node module and node modules of other vehicles that are sufficiently nearby to permit mesh network communication; uploading, through the VANET, vehicle parameters received by the node modules; uploading, through the VANET, signals from sensors reported to a node module; reporting, through the VANET, detection of a group of vehicles in a mesh network, a location of the group being propagated back through the VANET to inform of the presence of the group, to enable drivers to take appropriate precautions.

16 . The method of claim 16 , wherein a node module of a vehicle does not establish a mesh network with nearby node modules even if the nearby modules are sufficiently close unless a predetermined event occurs.

18 . The method of claim 17 wherein the predetermined event includes braking.

19 . The method of claim 17 wherein the predetermined event includes weather.

17 . The method of claim 17 wherein the predetermined event includes detection of a slow moving-object.
