Commercial Vehicle Databus --> Commercial Vehicle OBE:
host commercial vehicle status


host commercial vehicle status (Information Flow): Information provided to the Connected Vehicle on-board equipment from other systems on the Commercial Vehicle Platform.

Commercial Vehicle Databus (Source Physical Object): The 'Commercial Vehicle Databus' represents the interface to the heavy vehicle databus that connects on-board systems included in the commercial vehicle. This vehicle is used to transport goods, is operated by a professional driver and typically administered as part of a larger fleet. Commercial Vehicle classification applies to all goods transport vehicles ranging from small panel vans used in local pick-up and delivery services to large, multi-axle tractor-trailer rigs operating on long haul routes. It is a specialized and extended form of the Vehicle Databus that may be subject to different vehicle databus standards and connect with a broad range of components that are specific to commercial vehicles including the systems that are used to monitor, secure, and maintain freight while enroute. As a specialized form of the Vehicle Databus, it also provides access to the general-purpose sensors (e.g., radars, cameras), GPS, drive train monitoring and control systems, and vehicle safety features that support connected vehicle applications.

Commercial Vehicle OBE (Destination Physical Object): The Commercial Vehicle On-Board Equipment (OBE) resides in a commercial vehicle and provides the sensory, processing, storage, and communications functions necessary to support safe and efficient commercial vehicle operations. It provides two-way communications between the commercial vehicle drivers, their fleet managers, attached freight equipment, and roadside officials. In CVRIA, a separate 'Vehicle OBE' physical object supports the general V2V and V2I safety applications and other applications that apply to all vehicles, including commercial vehicles. The Commercial Vehicle OBE supplements these general capabilities with capabilities that are specific to commercial vehicles.
