CARTOGRAPHIC INFORMATION CORRECTION METHOD, DRIVING ASSISTANCE METHOD AND CARTOGRAPHIC INFORMATION CORRECTION DEVICE Russian patent published in 2023 - IPC G01C21/32 

FIELD: cartography.

SUBSTANCE: method for correcting cartographic information, method for assisting driving, and device for correcting cartographic information. The cartographic information correction method includes lane boundary line information, wherein the position with respect to the own vehicle (V) of the lane boundary line actually installed on the road surface around the own vehicle is detected. Then evaluate own position on the map of own vehicle; and correct, depending on the estimated own position and the detected position of the lane boundary line, the position of the lane boundary line included in the cartographic information, in the first area, relatively close to the own vehicle, by a larger amount of rotational correction than in the second area, relatively far from own vehicle, and in the second area by a greater amount of shear correction than in the first area.

EFFECT: providing the possibility of preventing a change in the behavior of the vehicle, even when the cartographic information, including information about the position of the lane boundaries, is corrected during the execution of the driving assistance control.
