Description

Connected vehicle technology enables cars, trucks, buses, and other vehicles to "talk" to each other with in–vehicle or aftermarket devices that continuously share important safety and mobility information. Fully automated, autonomous, or "self–driving" vehicles are defined by the U.S. DOT's National Highway Traffic Safety Administration (NHTSA) as "those in which operation of the vehicle occurs without direct driver input to control the steering, acceleration, and braking and are designed so that the driver is not expected to constantly monitor the roadway while operating in self–driving mode."

Functional Objects

Functional ObjectDescriptionUser 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 Communications Support'Vehicle Communications Support' supports secure, reliable communications with other connected devices. It provides the communications functions that add a timestamp, the message origin, and a digital signature in outbound messages and processes, verifies, and authenticates the same fields in inbound messages. It also encrypts (outbound) and decrypts (inbound) sensitive data.False
Vehicle Control Automation'Vehicle Control Automation' provides lateral and/or longitudinal control of a vehicle to allow 'hands off' and/or 'feet off' driving, automating the steering, accelerator, and brake control functions. It builds on the sensors included in 'Vehicle Safety Monitoring' and 'Vehicle Control Warning' and uses the information about the area surrounding the vehicle to safely control the vehicle. It covers the range of incremental control capabilities from driver assistance systems that take over steering or acceleration/deceleration in limited scenarios with direct monitoring by the driver to full automation where all aspects of driving are automated under all roadway and environmental conditions.False
Vehicle Control Warning'Vehicle Control Warning' monitors areas around the vehicle and provides warnings to a driver so the driver can take action to recover and maintain safe control of the vehicle. It includes lateral warning systems that warn of lane departures and obstacles or vehicles to the sides of the vehicle and longitudinal warning systems that monitor areas in the vehicle path and provide warnings when headways are insufficient or obstacles are detected in front of or behind the vehicle. It includes on–board sensors, including radars and imaging systems, and the driver information system that provides the visual, audible, and/or haptic warnings to the driver.False
Vehicle Data Subscription Management'Vehicle Data Subscription Management' manages data subscriptions for an end user. It provides access to a catalog of available data, manages the necessary user information and rules that govern the data subscriptions, supports communications with data providers to collect data per the subscription rules, and makes the data available to the end user. It provides the local user interface through which a user can specify and manage subscriptions. It supports different mechansims for collecting data for the end–user including one–time query–response as well as publish–subscribe services.False
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.False
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.False
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.False
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.False
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.
False
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.False
Vehicle Support Services'Vehicle Support Services' provides foundational functions that supports data collection, management, and distribution. It coordinates with Object Registration and Discovery to acquire necessary communications information. It maintains the necessary security credentials, authorizations, and associated keys to support communications in the connected vehicle environment.False
Vehicle System Executive'Vehicle System Executive' provides the operating system kernal and executive functions that manage the software configuration and operation and support computer resource management, security, and software installation and upgrade.False
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.False
Vehicle Trust Management'Vehicle Trust Management' manages the certificates and associated keys that are used to sign, encrypt, decrypt, and authenticate messages. It communicates with the Security and Credentials Management System to maintain a current, valid set of security certificates and identifies, logs, and reports events that may indicate a threat to the Connected Vehicle Environment security.False
