PATH CONTROL SYSTEM Russian patent published in 2023 - IPC B61K9/08 

FIELD: vehicle path control system.

SUBSTANCE: path control system comprises a position and orientation measuring unit configured to determine the geographic position and orientation of the system during at least one passage of the vehicle along the path, an information carrier for storing path geometry data, a laser imaging and/or scanning unit configured to determine the position of the at least one rail relative to the track control system and the position of the at least one rail and the environment relative to the track control system, during at least one pass, and the processor. The processor is configured to determine, in at least one pass, a first georeferenced rail position, based on the geographic position and orientation of the rail monitoring system and the position of the at least one rail relative to the system, determine, in at least one pass, a second georeferenced rail position, based on the geographic position and orientation of the rail inspection system and the position of at least one rail and surroundings relative to the rail inspection system, determining a third georeferenced rail position based on the first and second georeferenced rail positions and corresponding georeferenced track geometry data, receiving, in the additional pass, track geometry data associated with each rail position relative to the rail monitoring system, and the output of the position and orientation measurement unit, updating, based on the third georeferenced rail position, the track geometry data obtained in the additional pass, and saving updated path geometry data on a storage medium.

EFFECT: as a result, it is possible to collect and update data on track geometry during one pass of a vehicle moving at high speed along its trajectory, and the quality of track control is improved.
