Vehicular navigation based on site specific sensor quality data
First Claim
1. A method for determining a location of a vehicle, the method comprising:
- establishing a first zone in a work area, the first zone being where reception location data is applied exclusively as refined location data;
establishing a second zone in the work area, the second zone being where optical location data is applied exclusively as refined location data;
determining at least one of reception location data and optical location data to estimate preliminary location data indicating whether the vehicle is located in the first zone or the second zone; and
selecting at least one of the reception location data and the optical location data as refined location data based on whether the preliminary indication data falls within the established first zone or the second zone.

Abstract
A method and system for determining a location of a vehicle, the method comprises determining reception location data within a first cell of a work area for a vehicle. A reception quality estimator estimates reception quality data for the corresponding reception location data for the first cell. Optical location data is determined within a first cell of a work area for a vehicle. An optical quality estimator estimates optical quality data for the corresponding optical location data for the first cell. A data processor selects at least one of the reception location data and the optical location data as refined location data associated with the first cell based on the estimated reception quality data and estimated optical quality data.

9. A method for determining a location of a vehicle, the method comprising:
-
establishing a first zone in a work area, the first zone being where reception location data is applied exclusively as refined location data;
establishing a second zone in the work area, the second zone being where optical location data is applied exclusively as refined location data;
establishing a third zone in a the work area, the third zone being where optical location data is applied exclusive as refined location data;
determining at least one of reception location data, optical location data, and dead-reckoning location data to estimate preliminary location data indicating whether the vehicle is located in the first zone, the second zone, or the third zone; and
selecting at least one of the reception location data and the optical location data as refined location data based on whether the preliminary indication data falls within the established first zone, the established second zone, or the established third zone.

18. A system for determining a location of a vehicle, the system comprising:
-
a reception quality estimator for establishing a first zone in a work area, the first zone being where reception location data is applied exclusively as refined location data;
an optical quality estimator for establishing a second zone in the work area, the second zone being where optical location data is applied exclusively as refined location data;
a location-sensing system for determining at least one of reception location data and optical location data to estimate preliminary location data indicating whether the vehicle is located in the first zone or the second zone; and
a data processor for selecting at least one of the reception location data and the optical location data as refined location data based on whether the preliminary indication data falls within the established first zone or the second zone. - View Dependent Claims (19)
