Commercial Vehicles - Vehicle Functionality
Subsystem Description
This subsystem provides the sensory, processing, storage, and communications functions necessary to support efficient, safe, and convenient travel. These functions reside in general vehicles including personal automobiles, commercial vehicles, emergency vehicles, transit vehicles, or other vehicle types. Information services provide the driver with current travel conditions and the availability of services along the route and at the destination. Both one-way and two-way communications options support a spectrum of information services from low-cost broadcast services to advanced, pay for use 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. Initial collision avoidance functions provide “vigilant co-pilot” driver warning capabilities. More advanced functions assume limited control of the vehicle to maintain safe headway. Ultimately, this subsystem supports completely automated vehicle operation through advanced communications with other vehicles in the vicinity and in coordination with supporting infrastructure subsystems. Pre-crash safety systems are deployed and emergency notification messages are issued when unavoidable collisions do occur.
Functional Area: Vehicle Location Determination
Receives current location of the vehicle from GPS or other positioning technology and provides this information to other in-vehicle functions.
| ID | Requirement | Status |
|---|---|---|
| 1 | The vehicle shall provide the vehicle's current location to other in-vehicle functions. | Planned |
| 2 | The vehicle shall calculate the location from one or more data sources including positioning systems such as GPS, sensors that track vehicle movement, and maps used to determine the likely vehicle route. | Planned |
Functional Area: Vehicle Mayday I/F
In-vehicle capability for drivers or collision detection sensors onboard a vehicle to report an emergency and summon assistance.
| ID | Requirement | Status |
|---|---|---|
| 1 | The vehicle shall provide the capability for a driver to report an emergency and summon assistance. | Planned |
| 2 | The vehicle shall provide the capability to accept input from a driver via a panic button or some other functionally similar form of input device provided as part of the in-vehicle equipment. | Planned |
| 4 | The vehicle shall forward a request for assistance to a center containing the driver's current location, its identity and basic vehicle data relevant to its current condition, as well as any other data, such as personal medical history, vehicle orientation, etc., that may be developed in-vehicle by other systems. | Planned |
| 5 | The vehicle shall acknowledge the driver's request for emergency assistance. | Planned |
| 6 | The vehicle shall provide further details about the emergency to the center upon request from that function. | Planned |
