Abstract
A navigation system suitable for use by an automated vehicle includes a first sensor, a second sensor, a digital-map, and a controller. The digital-map includes a first data-group of navigation-features preferentially detected by the first sensor-technology, and a second data-group of navigation-features preferentially detected by the second sensor-technology. The controller determines, on the digital-map, first and second locations of the host-vehicle using the first and second sensors, respectively. The controller selects one of the first and second locations to navigate the host-vehicle based on a comparison of the first data-density and the second data-density. Alternatively, the controller determines a first feature-density and a second feature-density of navigation-features detected by the first and second sensors respectively, and selects one of the first location and the second location to navigate the host-vehicle based on a comparison of the first feature-density and the second feature-density.
