Vehicle Basic Safety Communication Functional Area


'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.

Functional Requirements

01The vehicle shall provide its location with lane–level accuracy to on–board applications.
02The vehicle shall provide its location with road–level accuracy to on–board applications.
03The vehicle shall collect road condition data from other vehicles.
04The vehicle shall calculate vehicle paths in order to determine if an impending collision is detected.
05The vehicle shall exchange location and motion information with roadside equipment and nearby vehicles.
06The vehicle shall be able to receive warnings, informational road signs, traffic meters, and signals provided by infrastructure devices.
07The vehicle shall warn the driver of an Emergency Electronic Brake Light (EEBL) Event.
08The vehicle shall determine when its host Vehicle is braking in an emergency fashion and broadcast an Emergency Electronic Brake Light (EEBL) notification.
09The vehicle shall determine the status of host vehicle systems including vehicle speed, heading, yaw, wheelspin, ABS, traction control, and wiper status.
10The vehicle shall determine if vehicle systems status indicates a potentially hazardous road condition.
11The vehicle shall analyze its own applications' performance and enter fail–safe mode (a mode such that the application cannot provide information or perform actions that affect its host) when critical components fail.
12The vehicle shall notify the driver when onboard components or safety applications are offline.
