Municipal Maintenance 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 Environmental Probe Support
Vehicle probes with added capability and intelligence to sense and send road conditions as the vehicle travels; may include road conditions and surface weather information.
| ID | Requirement | Status |
|---|---|---|
| 1 | The vehicle shall collect and process environmental sensor data, including air temperature and rain sensors. | Planned |
| 2 | The vehicle shall monitor the status of vehicle convenience and safety systems (wiper status, headlight status, traction control system status) that can be used to measure environmental conditions and record snapshots of significant events in these systems. | Planned |
| 3 | The vehicle shall transmit environmental probe data to the center along with location and timestamp information. | Planned |
| 4 | The vehicle shall transmit environmental probe data to field equipment located along the roadway using short range communications. | Planned |
Functional Area: Vehicle Safety Monitoring System
On-board systems to diagnose critical components of the vehicle and warn the driver of potential dangers, including steering, braking, acceleration, emissions, fuel economy, engine performance, etc.
| ID | Requirement | Status |
|---|---|---|
| 1 | The vehicle shall collect and monitor data concerning the safety of the vehicle - including, steering, braking, acceleration, emissions, fuel economy, engine performance, etc. | Planned |
| 2 | The vehicle shall determine the status of the vehicle in terms of its continued ability to operate in a safe manner. | Planned |
| 3 | The vehicle shall provide warnings to the driver of potential dangers based on sensor input and analysis concerning the safety of the vehicle. | Planned |
| 4 | The vehicle shall present information to the driver in audible or visual forms without impairing the driver's ability to control the vehicle in a safe manner. | Planned |
