Abstract
A method controls the height of a floor of a car of a vehicle relative to a platform. The car includes a body provided with a distance sensor, at least one bogie and at least one secondary suspension between the bogie and the body. The method includes measuring the distance between the distance sensor and the platform via the distance sensor, calculating the difference between the height of the platform and the height of the floor from the measured distance, and adjusting the height of the secondary suspension based on the difference.
