Abstract
A method for determining a location of a vehicle. The method includes steps of acquiring a plurality of sensor data from a radar sensor associated with the vehicle; obtaining an approximate location of the vehicle using a GPS unit; comparing the sensor data to a database of geo-referenced sensor data; and based on the comparison, determining a location of the vehicle.
Claims17
A method for determining a location of a vehicle, comprising:
- acquiring a plurality of sensor data traces from a radar sensor associated with the vehicle;
- obtaining velocity information from the plurality of sensor data traces;
- using the velocity information, identifying a portion of the plurality of sensor data traces corresponding to a moving object;
- removing the portion of the plurality of sensor data traces corresponding to the moving object from the plurality of sensor data traces;
- obtaining an approximate location of the vehicle using a GPS unit;
- comparing the sensor data traces to a database of geo-referenced sensor data traces;
- and
- based on the comparison, determining the location of the vehicle.

A system for determining a location of a vehicle, comprising:
- a vehicle having at least one radar sensor and a GPS unit associated therewith;
- a controller in communication with the at least one radar sensor and the GPS unit, the controller configured to
- acquire a plurality of sensor data traces from the radar sensor associated with the vehicle;
- obtain velocity information from the plurality of sensor data traces;
- using the velocity information, identify a portion of the plurality of sensor data traces corresponding to a moving object;
- remove the portion of the plurality of sensor data traces corresponding to the moving object from the plurality of sensor data traces;
- compare the sensor data traces to a database of geo-referenced sensor data traces;
- and
- based on the comparison, determine the location of the vehicle.
