Transitioning to a roadside unit state
First Claim
1. A method performed by one or more processors, comprising:
- receiving, at an interface of a vehicular device that is associated with the one or more processors, a notification message indicative of an occurrence of an event, wherein the interface is configured for communication with the one or more processors of the vehicular device;
determining that a position of the vehicular device is located on a boundary of a reachability area surrounding a source of the event, the boundary of the reachability area being the position of the vehicular device proximate to (i) one or more vehicular devices that are informed of the occurrence of the event and that are located inside of the reachability area, and (ii) one or more vehicular devices that are uninformed of the occurrence of the event and that are located outside of the reachability area;
determining that a direction of movement of the vehicular device is towards the source;
responsive to determining that the position is on the boundary of the reachability area and that the direction of movement of the vehicular device is towards the source, automatically controlling an operational state of the vehicular device for entering a roadside unit state in which the vehicular device acts a roadside unit for a pre-defined period of time;
detecting the one or more vehicular devices that are uninformed of the occurrence of the event and that are located outside of the reachability area; and
broadcasting the notification message to the one or more uninformed vehicular devices.

11. One or more non-transitory machine-readable media configured to store instructions that are executable by one or more processors to perform operations comprising:
- receiving, at an interface of a vehicular device that is associated with the one or more processors, a notification message indicative of an occurrence of an event, wherein the interface is configured for communication with the one or more processors of the vehicular device;
determining that a position of the vehicular device is located on a boundary of a reachability area surrounding a source of the event, the boundary of the reachability area being the position of the vehicular device proximate to (i) one or more vehicular devices that are informed of the occurrence of the event and that are located inside of the reachability area, and (ii) one or more vehicular devices that are uninformed of the occurrence of the event and that are located outside of the reachability area;
determining that a direction of movement of the vehicular device is towards the source;
responsive to determining that the position is on the boundary of the reachability area and that the direction of movement of the vehicular device is towards the source, automatically controlling an operational state of the vehicular device for entering a roadside unit state in which the vehicular device acts a roadside unit for a pre-defined period of time;
detecting the one or more vehicular devices that are uninformed of the occurrence of the event and that are located outside of the reachability area; and
broadcasting the notification message to the one or more uninformed vehicular devices. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
