Vehicle On-Board Equipment
Status: Existing
Description
Vehicle on–board equipment (OBE) provides the vehicle–based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel.
Stakeholders
Physical Objects
Functional Objects
| Functional Object | Description | User Defined |
|---|
| Vehicle Basic Safety Communication | 'Vehicle Basic Safety Communication' exchanges current vehicle location and motion information with other vehicles in the vicinity, uses that information to calculate vehicle paths, and warns the driver when the potential for an impending collision is detected. If available, map data is used to filter and interpret the relative location and motion of vehicles in the vicinity. Information from on–board sensors (e.g., radars and image processing) are also used, if available, in combination with the V2V communications to detect non–equipped vehicles and corroborate connected vehicle data. Vehicle location and motion broadcasts are also received by the infrastructure and used by the infrastructure to support a wide range of roadside safety and mobility applications. This object represents a broad range of implementations ranging from basic Vehicle Awareness Devices that only broadcast vehicle location and motion and provide no driver warnings to advanced integrated safety systems that may, in addition to warning the driver, provide collision warning information to support automated control functions that can support control intervention. | False |

| Vehicle Speed Management Assist | 'Vehicle Speed Management Assist' assists the driver in operating the vehicle within the current speed limit. It monitors current vehicle speed and communicates with the infrastructure to receive current speed limits and associated road configuration change notifications. Driver warnings are issued when unsafe or excessive speeds are detected based on the provided speed limits and current conditions. | False |
|---|
| Vehicle Traveler Information Reception | 'Vehicle Traveler Information Reception' receives advisories, vehicle signage data, and other driver information of use to all types of vehicles and drivers and presents this information to the driver using in–vehicle equipment. Information presented may include fixed sign information, traffic control device status (e.g., signal phase and timing data), advisory and detour information, warnings of adverse road and weather conditions, travel times, and other driver information. | False |
