Method for Determining an Object's Position Using Different Items of Sensor Information

A method for determining an object's position using different items of sensor information includes: a) reading the sensor information into a Kalman filter, b) merging the sensor information with the Kalman filter, with the Kalman filter supplying as a result estimated values for states and information associated with the estimated values regarding the accuracy of the estimates, c) monitoring the results of the Kalman filter by estimating a probability of accuracy, with which the estimation error lies within an error band, with the probability of accuracy being determined on the basis of a plurality of conditional probabilities, the conditions for which each relate to estimation errors from at least one earlier series.
