In a method for the probabilistic estimation of measurements, based on a measurement signal in which an interference signal is superimposed on the value to be measured, the measurement signal is sampled at specified chronological intervals. A defined measurement range associated with the value to be measured is divided into discrete values and a model is formed of a process on which the measurement signal is based with discrete states that correspond to the discrete values of the measurement range. In the model, a probability value of the occurrence of each state is assigned for each sampling time, and the value to be measured is determined on the basis of the probability value of at least one state in this model. In addition, for each state of the model at a sampling time, a probability for the state to remain in its current state is determined, as well as a probability for the state to change to another state by the next sampling time. On the basis of the value of the measurement signal sampled in a current sampling time, the probability value for the occurrence of the states in the preceding sampling time and the probability for each state to remain unchanged and to change to another state between the two sampling times, the probability values for the occurrence of the states of the model for the current sampling time are recalculated.
