摘要： Method for determining states of a system by means of an estimation filter, in which first state values are determined by calculating a mean value of a probability distribution for the states, in which a probability for deviation for the case that the first state values deviate from the actual states of the system is calculated, and in which the states of the system are measured as state data. In the method the first state values are corrected by means of the state data then, if the probability for deviation is larger than a threshold.
