Abstract
A system includes a processor and a memory. The memory stores instructions executable by the processor to select a technique, from a plurality of techniques, to identify a vehicle location by sensor and map data based on features detected in sensor data of an area in which the vehicle is located, to determine a location of the vehicle based on the selected technique; and to navigate the vehicle based at least in part on the identified location.
Claims17
A system, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- determine a selected technique, from a plurality of techniques, to identify a vehicle location by sensor and map data based on features detected in sensor data of an area in which the vehicle is located by:
- determining a first ratio of a first number of available points in a first map based on a first technique from the plurality of techniques divided by a first minimum number of points for detecting the location based on the first map;
- determining a second ratio of a second number of available points in a second map based on a second technique from the plurality of techniques divided by a second minimum number of points for detecting the location based on the second map;
- selecting the first technique as the selected technique upon determining that the first ratio is greater than the second ratio;
- and
- determining the location of the vehicle based on the first map and data received from a vehicle sensor;
- determine a location of the vehicle based on the selected technique;
- and
- navigate the vehicle based at least in part on the identified location.
