METHOD FOR DETECTING SYSTEMATIC DEVIATIONS DURING DETERMINATION OF A MOVEMENT VARIABLE OF A GROUND-BASED, MORE PARTICULARLY RAIL-BASED, VEHICLE

A method detects systematic deviations during a determination of a movement variable of a ground-based, more particularly rail-based, vehicle. To optimize the operation of the vehicle, more particularly to minimize operational restrictions during operation of the vehicle, the method proposes that—based on a measurement value, assigned to a time, of at least one sensor, a value, assigned to the time, of the movement variable is determined and—subject to the value, assigned to the time, of the movement variable and a statistical sensor accuracy value, determined for this value, of the at least one sensor, a test variable value, assigned to the time, is formed and is compared in a comparison with a predefined test bound in order to make an assumption regarding an existence of a systematic deviation. The assumption is subject to a comparison result obtained from the comparison.
