Abstract

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.
