Method for detecting systematic deviations during determination of a movement variable of a ground-based, more particularly rail-based, vehicle

A configuration for detecting systematic deviations during determination of a movement variable of a ground-based vehicle, the configuration comprising:

• at least one sensor;
• and
• a computer configured to detect the systematic deviations during the determination of the movement variable of the ground-based vehicle, said computer being programmed to:
• determine a value of the movement variable associated with a time point on a basis of a measurement value, associated with the time point, of said at least one sensor;
• form a test variable value associated with the time point dependent upon the value, associated with the time point, of the movement variable and upon a statistical sensor accuracy value of said at least one sensor determined for the value;
• further form the test variable value in dependence on an expected value of the movement variable for the time point;
• compare the test variable value with a specified test limit, in order to make an assumption, dependent upon a comparison result obtained from a comparison, with regard to an existence of a systematic deviation:
• determine an expected system state of the ground-based vehicle or the time point on a basis of a movement model applied to a previous system state of the ground-based vehicle;
• determine the expected value of the movement variable for the time point on a basis of a transfer model applied to the expected system state;
• change the movement variable of the ground-based vehicle such that a slippage of wheels of the ground-based vehicle on a ground or rails is substantially prevented by brakes of the ground-based vehicle or by a drive of the ground-based vehicle.
