Patent ID: 11967160
Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. An own position inferring device comprising:
a sensor white line detector to detect a white line position on the basis of an output from an on-vehicle sensor;
a sensor point group extractor to extract first point group information from the white line position detected by the sensor white line detector;
an own position detector to measure an own position on the basis of an output from a position measurement device;
a map white line acquisition circuitry to acquire a white line position from map information about a region around the own position detected by the own position detector;
a map point group extraction circuitry to extract second point group information from the white line position acquired from the map information by the map white line acquisition circuitry;
a point group extraction condition changer to change a point group extraction condition for the sensor point group extraction unit and the map point group extractor;
a white line position matching circuitry to perform position matching between the first point group information extracted by the sensor point group extractor and the second point group information extracted by the map point group extractor; and
an own position corrector to correct the own position on the basis of a result of the position matching circuitry performed by the white line position matching circuitry.
