Local Maintenance and Construction Vehicles - 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 Environmental Monitoring
'Vehicle Environmental Monitoring' collects data from on–board sensors and systems related to environmental conditions and sends the collected data to the infrastructure as the vehicle travels. The collected data is a byproduct of vehicle safety and convenience systems and includes ambient air temperature and precipitation measures and status of the wipers, lights, ABS, and traction control systems.
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 Map Management
'Vehicle Map Management' supports map updates and makes current map and geometry data available to other applications. It manages map data on–board and provides map data to end–user applications that provide location–based services.
Functional Object: Vehicle Safety Monitoring
'Vehicle Safety Monitoring' monitors critical components of the vehicle and warns the driver of safety issues. These capabilities are provided by on–board sensors that monitor vehicle condition and performance, including steering, braking, acceleration, emissions, fuel economy, engine performance, etc.
This functional object can also monitor the driver's condition and warn the driver of potential safety issues. It includes sensors and behavior monitoring capabilities that assess the suitability of the driver (e.g., fitness and alertness) to assume or maintain manual control of the vehicle.
Functional Object: Vehicle Secure Area Access System
'Vehicle Secure Area Access System' provides access to secure areas such as shipping yards, warehouses, airports, transit–only ramps, parking gates and other areas. It accepts inputs from the vehicle driver that include the necessary identity information and uses this information to generate the request to activate a barrier to gain access to the area.
Functional Object: Vehicle System Executive
'Vehicle System Executive' provides the operating system kernel and executive functions that manage the software configuration and operation and support computer resource management, security, and software installation and upgrade.
Functional Object: Vehicle System Monitoring and Diagnostics
'Vehicle System Monitoring and Diagnostics' includes on–board sensors and integrated self test software that monitors the condition of each of the vehicle systems and diagnostics that can be used to support vehicle maintenance. The status of the vehicle and ancillary equipment and diagnostic information is provided to the driver and service center.
