A method for determining an integrity range of a parameter estimation is disclosed. The integrity range describes the range in which an estimated parameter lies with a minimum probability. The method includes at least the following steps: a) ascertaining first integrity information on the basis of at least data from at least one first sensor or on the basis of a first method for determining the integrity information, b) ascertaining second integrity information on the basis of at least data from at least one second sensor that is different from the first sensor or on the basis of a second method that is different from the first method, for determining the integrity information, and c) determining the integrity range by merging at least the first integrity information and the second integrity information.

Method for determining an integrity range

A method for the adaptive ascertainment of an integrity range of a parameter estimate, the integrity range describing the range within which an estimated parameter is located with a minimum probability. The method includes: a) Ascertaining basic integrity information with the aid of a base module of a modular system, b) ascertaining an item of first supplementary integrity information with the aid of a first supplementary module of the modular system if at least one precondition for the ascertaining of the item of first supplementary integrity information has been satisfied, c) ascertaining the integrity range using at least the item of basic integrity information or at least the basic integrity information and the item of first supplementary integrity information if the first item of supplementary integrity information was ascertained.

The disclosure concerns a method for ascertaining at least one piece of integrity information relating to a location result of a GNSS-based location device of a vehicle in the event of an abruptly and significantly changing GNSS reception situation, comprising at least the following steps: (a) ascertaining the current ego position of the vehicle by means of the GNSS-based location device; (b) ascertaining at least one piece of integrity information relating to the ego position ascertained in step (a), by means of the GNSS-based location device; (c) detecting an abruptly and significantly changing or significantly altered GNSS reception situation; and (d) adapting the ascertainment of the at least one piece of integrity information for the changing or altered GNSS reception situation.
