DEVICE FOR EVALUATION OF POSITION OF VEHICLE AND METHOD FOR ESTIMATING POSITION OF VEHICLE Russian patent published in 2019 - IPC G01C21/30 

FIELD: transportation.

SUBSTANCE: disclosed group of inventions relates to means of assessing the position of vehicles. Device for estimating the position of a vehicle comprises: a unit for detecting positions of the target object; unit for detecting movement value; target object storage unit; unit for obtaining cartographic information; a vehicle position evaluation unit configured to, by comparing the position data of the target object stored in the target object storage unit with the target object positions in the map information, evaluate the position of the vehicle near the vehicle; and a turning point detecting unit configured to detect a turning point of the vehicle from vehicle movement values. At that, the target object storage unit saves in memory at least the target object positions data in the range going back from the current location to the predetermined first specified distance, and target object position data in the range going back from the turning point to a predetermined second predetermined distance. Said device implements corresponding method of vehicle position evaluation.

EFFECT: this group of inventions allows, together with preservation of accuracy of evaluation of vehicle positions, enabling adjustment of the number of data of positions of the target object.
