Abstract
A method for measuring a parameter relevant to a journey of a rail vehicle. A parameter measurement value is determined using a control loop. A vehicle-side torque acting on a rotational part on the vehicle side is ascertained. A calculation module uses the vehicle-side torque value and a frictional engagement torque acting between the rotational part and a rail, to calculate a rotational acceleration of the rotational part and an expected rotational speed. A difference between the rotational estimated value and an actual rotational speed is supplied to a control device which outputs a controller output value at the output side. A frictional engagement torque value is recalculated with the controller output value and is coupled back into the computer module to close the control loop. The controller output and/or the recalculated frictional engagement torque value is considered the parameter measurement value, which is stored or output.
