Emergency Vehicle OBE --> Vehicle:
vehicle maneuver coordination

Definitions

vehicle maneuver coordination (Information Flow): Statements of intent, permission and status of a lane change or merge operation by a connected vehicle

Emergency Vehicle OBE (Source Physical Object): The 'Emergency Vehicle On-Board Equipment' (OBE) resides in an emergency vehicle and provides the processing, storage, and communications functions that support public safety-related connected vehicle applications. It represents a range of vehicles including those operated by police, fire, and emergency medical services. In addition, it represents other incident response vehicles including towing and recovery vehicles and freeway service patrols. It includes two-way communications to support coordinated response to emergencies. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including emergency vehicles. The Emergency Vehicle OBE supplements these general capabilities with capabilities that are specific to emergency vehicles.

Vehicle (Destination Physical Object): This 'Vehicle' physical object is used to model core capabilities that are common to more than one type of Vehicle. It provides the vehicle-based general sensory, processing, storage, and communications functions that support efficient, safe, and convenient travel. 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 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. Both one-way and two-way communications options support a spectrum of information services from basic broadcast to advanced personalized information services. 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.

Communication Solutions

  • US: SAE Maneuver Coordination - LTE-V2X WSMP (10)
Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

US: SAE Maneuver Coordination - LTE-V2X WSMP

Solution Description

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Maneuver Coordination with those for V-X: LTE-V2X WSMP. The US: SAE Maneuver Coordination standards include upper-layer standards required to enable maneuver coordination between equipped vehicles. The V-X: LTE-V2X WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C-V2X in the 5.9GHz spectrum.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Low High Low
Basis Data contained within this flow is intended to alert other nearby vehicles to a desired or impending movement by the source vehicle. The data does include identifiers indicating the sending vehicle, which needs to be recognized and protected as appropriate. It may be impractical to encrypt this data to meet performance requirements, and in any event no more than one vehicle would be identified and only in the field environment, so mass collection of this information would be difficult. This flow is core to automated vehicle merge and lane change operations; flaws in the data could result in a crash, and so integrity should be ensured to the highest practical level. L4/5 ADS will operate more smoothly if this flow works, but as the vehicle fleet will include L0 vehicles for the foreseeable future, any ADS must use other methods to ensure safe operation anyway. May be MODERATE in ADS-dedicated facilities.
