vehicle commands

Definitions

vehicle commands (Information Flow): System-level control commands issued to vehicle equipment such as reset and remote diagnostics.

Vehicle Application and Service Center (Source Physical Object): 'Vehicle Application and Service Center' (VSAC) represents centers that provide telematics services to vehicles using wide-area (e.g. cellular) communications, including traveler information, emergency services, vehicle diagnostics, and provision of service options for these vehicles. See also 'Transportation Information Center' that provides traveler information, trip planning, and routing services and 'Emergency Management Center' that provides call-taking and emergency response services that may also be implemented by a VASC.

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 (including motorcycles), 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

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - Secure Wireless Internet (EU)

Solution Description

This solution is used within Australia and the E.U.. It combines standards associated with (None-Data) with those for I-M: Secure Wireless Internet (EU). The (None-Data) standards include an unspecified set of standards at the upper layers. The I-M: Secure Wireless Internet (EU) standards include lower-layer standards that support secure communications between two entities, either or both of which may be mobile devices, but they must be stationary or only moving within wireless range of a single wireless access point (e.g., a parked car). Security is based on X.509 certificates. A non-mobile (if any) endpoint may connect to the service provider using any Internet connection method.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Security

Information Flow Security
  Confidentiality Integrity Availability
Rating Moderate High Moderate
Basis Commands could be sensitive and should include authentication data, thus should be MODERATE. Invalid or corrupted vehicle control commands could have a significant safety impact, depending on the level of isolation between the Vehicle OBE and vehicle control systems. Without the ability to locally diagnose, operate, update and configure the Vehicle OBE, the OBE is effectively out of control and would have to be taken out of service. Marked MODERATE and not HIGH however because a vehicle system is presumed to be able to operate without a connection to a backoffice service. For specific instances where this flow is used as part of a local, in-person configuration or maintenance service, would be HIGH.
