Abstract

A navigation system for a restricted-use automated-vehicle includes a digital-map, a location-detector, and a controller. The digital-map characterizes roadways on the digital-map with a usage-rating. The usage-rating is indicative of a minimum-value of a vehicle-rating of a vehicle allowed to use each of the roadways. The location-detector indicates a location of a host-vehicle on the digital-map. The controller is in communication with the digital-map and the location-detector. The controller receives a destination of the host-vehicle, and determines a route from the location to the destination that avoids roadways with usage-ratings greater than the vehicle-rating of the host-vehicle.

Claims

1. A navigation system for a restricted-use automated-vehicle, said system comprising:

a digital-map that characterizes roadways on the digital-map with a usage-rating, wherein the usage-rating is indicative of a minimum-value of a vehicle-rating of a vehicle allowed to use each of the roadways;

a location-detector that indicates a location of a host-vehicle on the digital-map; and

a controller in communication with the digital-map and the location-detector, said controller receives a destination of the host-vehicle, and determines a route from the location to the destination that avoids roadways with usage-ratings greater than the vehicle-rating of the host-vehicle.

2. The system in accordance with claim 1, wherein the usage-rating is based on a speed-limit of the roadway, and the route avoids roadways where the speed-limit is greater than a speed-threshold of the host-vehicle.

3. The system in accordance with claim 2, wherein the route crosses roadways characterized by a speed-limit greater than the speed-threshold only where a traffic-control-device is present that momentarily stops cross-traffic of the roadway.

4. The system in accordance with claim 1, wherein the usage-rating is based on a time-of-day, and the route avoids a roadway when usage-rating of the roadway is greater than the vehicle-rating of the host-vehicle.

5. The system in accordance with claim 1, wherein the usage-rating of a roadway is determined dynamically based on information from a road-sensor, and the route avoids a roadway when the usage-rating of the roadway is greater than the vehicle-rating of the host-vehicle.

6. The system in accordance with claim 1, wherein the usage-rating is based on a vertical-slope of a roadway, and the route avoids the roadway when the vertical-slope is greater than a slope-threshold of the host-vehicle.

7. The system in accordance with claim 1, wherein the usage-rating is based on a maximum-weight of vehicles allowed to operate on a roadway, and the route avoids the roadway when the maximum-weight is greater than a weight-threshold of the host-vehicle.

8. The system in accordance with claim 1, wherein the usage-rating is based on an accident-history of a roadway, and the route avoids the roadway when the accident-history of the roadway is greater than an accident-threshold of the host-vehicle.
