Private Vehicle - Vehicle OBE Functionality
Subsystem Description
The Vehicle On–Board Equipment (OBE) provides the vehicle–based sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. The Vehicle OBE includes general capabilities that apply to passenger cars, trucks, and motorcycles. Many of these capabilities (e.g., see the Vehicle Safety service packages) 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. The radio(s) supporting V2V and V2I communications are a key component of the Vehicle OBE. Both one–way and two–way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. Route guidance capabilities assist in formulation of an optimal route and step by step guidance along the travel route. Advanced sensors, processors, enhanced driver interfaces, and actuators complement the driver information services so that, in addition to making informed mode and route selections, the driver travels these routes in a safer and more consistent manner. This physical object supports all six levels of driving automation as defined in SAE J3016. Initial collision avoidance functions provide 'vigilant co–pilot' driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain lane position and safe headways. In the most advanced implementations, this Physical Object supports full automation of all aspects of the driving task, aided by communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems.
Functional Object: Vehicle Basic Toll/Parking Payment
'Vehicle Basic Toll/Parking Payment' includes the traditional on–board systems that pay for tolls and parking electronically. It includes the 'tag' in–vehicle equipment that communicates with the toll/parking plaza and an optional interface to a carry–in payment device. See also 'Vehicle Payment Services', which provides a broader range of payment services.
Functional Object: Vehicle Emergency Notification
'Vehicle Emergency Notification' provides the capability for drivers or collision detection sensors to report an emergency and summon assistance. It gathers data from on–board collision detection sensors, provides a mechanism for the driver to summon assistance, and includes a communications capability to report the collision including indicators of collision severity, the number of passengers involved, and information about the vehicle that may affect the response.
Functional Object: Vehicle Interactive Traveler Information
'Vehicle Interactive Traveler Information' provides drivers with personalized traveler information including traffic and road conditions, transit information, maintenance and construction information, multimodal information, event information, and weather information. The provided information is tailored based on driver requests. Both one–time requests for information and on–going information streams based on a submitted traveler profile and preferences are supported.
Functional Object: Vehicle Local Route Guidance
'Vehicle Local Route Guidance' provides route planning and turn by turn route guidance to a driver using computational resources and a digital map on–board the vehicle. It includes autonomous systems that are not configured to receive or process real–time information as well as systems that are equipped to receive real–time traffic and road conditions information from the infrastructure that are factored into the route selection and guidance algorithms.
Functional Object: Vehicle Location Determination
'Vehicle Location Determination' receives current location of the vehicle and provides this information to vehicle applications that use the location information to provide ITS services.
Functional Object: Vehicle Roadside Information Reception
'Vehicle Roadside Information Reception' receives advisories, vehicle signage data, and other driver information 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.
Functional Object: Vehicle Situation Data Monitoring
'Vehicle Situation Data Monitoring' is the highest–level representation of the functionality required to collect traffic and environmental situation data by monitoring and storing the experience of the vehicle as it travels through the road network. Collected data is aggregated into snapshots that are reported when communications is available and with flow control based on parameters provided by the infrastructure. Note that this functional object supports collection of data for areas remote from RSEs or other communications infrastructure.
Functional Object: Vehicle Traveler Information Reception
'Vehicle Traveler Information Reception' provides the capability for drivers to receive general transportation information including traffic and road conditions, traffic regulations, incident information, maintenance and construction information, event information, transit information, parking information, weather information, and broadcast alerts.
Functional Object: Vehicle Trip Planning and Route Guidance
'Vehicle Trip Planning and Route Guidance' includes the in–vehicle system that coordinates with a traveler information center to provide a personalized trip plan to the driver. The trip plan is calculated by the Transportation Information Center (TIC) based on preferences and constraints supplied by the driver and provided to the driver for confirmation. Reservations and advanced payment may also be processed to confirm the trip plan. Coordination with the TIC may continue during the trip so that the route plan can be modified to account for new information. Many equipment configurations are possible including in–vehicle systems that provide a basic trip plan to the driver as well as more sophisticated systems that can provide turn by turn guidance to the driver along the route.
