Automated vehicle sensor selection based on map data density and navigation feature density

1. A navigation system suitable for use by an automated vehicle, said system comprising:

a first sensor used to determine a first relative-position of a first navigation-feature relative to a host-vehicle, said first sensor characterized as based on a first sensor-technology;

a second sensor used to determine a second relative-position of a second navigation-feature relative to the host-vehicle, said second sensor characterized as based on a second sensor-technology different from the first sensor-technology;

a digital-map that includes a first data-group composed of navigation-features characterized as preferentially detected by the first sensor-technology, and a second data-group composed of navigation-features characterized as preferentially detected by the second sensor-technology; and

a controller in communication with the first sensor, the second sensor, and the digital-map, said controller configured to

determine a first location of the host-vehicle on the digital-map based on the first relative-position of the first navigation-feature indicated by the first sensor, wherein the first data-group of the digital-map proximate to the first location is characterized by a first data-density,

determine a second location of the host-vehicle on the digital-map based on the second relative-position of the second navigation-feature indicated by the second sensor, wherein the second data-group on the digital-map proximate to the second location is characterized by a second data-density, and

select one of the first location and the second location for use to navigate the host-vehicle based on a comparison of the first data-density and the second data-density.

2. The system in accordance with claim 1 , wherein the first sensor and the second sensor are each one of a camera, a radar-unit, and a lidar-unit, and the first sensor is different from the second sensor.

3. The system in accordance with claim 1 , wherein the first navigation-feature is associated with a first object and the second navigation-feature is associated with a second object different from the first object.

4. The system in accordance with claim 1 , wherein the first navigation-feature and the second navigation-feature are associated with a same object.

5. The system in accordance with claim 1 , wherein the host-vehicle is navigated in accordance with the first location when the first data-density is greater than the second data-density, and the host-vehicle is operated in accordance with the second location when the first data-density is not greater than the second data-density.

6. The system in accordance with claim 1 , wherein the controller is further configured to

determine an average-location based on the first location and the second location, and

navigate the host-vehicle in accordance with the average-location when the first data-density and the second data-density are both less than a data-threshold.

7. The system in accordance with claim 1 , wherein the system includes a location-device used to determine a third location of the host-vehicle on the digital-map.
