Abstract
A method for controlling a position of a floor of a carriage of a railway vehicle moving on rails, relative to a platform. The carriage includes a body including the floor, at least one bogie, and at least one suspension interposed between the body and the bogie. The method includes determining a level difference between the actual position of the carriage relative to the platform and an expected position of the carriage relative to the platform, adjusting a height of the suspension for compensating the determined level difference. Determining the level difference includes capturing an image of at least one predetermined pattern comprised on the platform with a camera borne by the body, comparing the captured image with a memorized reference image of the at least one pattern of the platform, and calculating a vertical displacement from the images to determine the level difference.
