A method for determining at least one integrity information regarding the location determination result of a vehicle's GNSS-based positioning device when the GNSS reception situation changes suddenly and significantly.

摘要

PROBLEM TO BE SOLVED: To determine at least one integrity information regarding a position identification result of a position identification device (2) based on the GNSS of a vehicle (1) when the GNSS reception situation suddenly and remarkably changes. Regarding the method. In the method, a) a step of identifying the current self-position of a vehicle (1) using a GNSS-based position specifying device (2), and b) a GNSS-based position specifying device (2). It is used to determine at least one integrity information about the self-position identified in step a), c) identify a sudden and significantly changed or significantly changed GNSS reception status, and d). A method comprising at least one step of determining integrity information, a step of adapting to a changed or altered GNSS reception situation. [Selection diagram] Fig. 1
