Vehicle OBE --> Remote Vehicle OBEs:
vehicle control event

This triple is bi-directional. See also Remote Vehicle OBEs --> Vehicle OBE: vehicle control event


vehicle control event (Information Flow): Notification that the vehicle has performed an emergency maneuver that could impact the safety of surrounding vehicles. This includes hard braking and activation of traction/stability control systems or other maneuvers that warrant immediate notification of surrounding vehicles. The information flow conveys the current vehicle location, path, and current control actions.

Vehicle OBE (Source Physical Object): The Vehicle On-Board Equipment (OBE) provides the vehicle-based processing, storage, and communications functions necessary to support connected vehicle operations. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. This communication platform is augmented with processing and data storage capability that supports the connected vehicle applications.

In CVRIA, the Vehicle OBE includes the functions and interfaces that support connected vehicle applications for passenger cars, trucks, and motorcycles. Many of these applications (e.g., V2V Safety applications) apply to all vehicle types including personal vehicles, commercial vehicles, emergency vehicles, transit vehicles, and maintenance vehicles. From this perspective, the Vehicle OBE includes the common interfaces and functions that apply to all motorized vehicles.

Remote Vehicle OBEs (Destination Physical Object): 'Remote Vehicle OBEs' represents other connected vehicles that are communicating with the host vehicle. This includes all connected motorized vehicles including passenger cars, trucks, and motorcycles and specialty vehicles (e.g., maintenance vehicles, transit vehicles) that also include the basic 'Vehicle OBE' functionality that supports V2V communications. In CVRIA, this object provides a source and destination for information transfers between connected vehicles. The host vehicle on-board equipment, represented by the Vehicle OBE physical object, sends information to, and receives information from the Remote Vehicle OBEs to model all connected vehicle V2V communications in CVRIA.
