Abstract: A method is for checking whether a digital road map correctly reproduces actual circumstances visible from at least one predefined pose. The method includes procuring observations of a scenario from the at least one predefined pose, determining an actual behavior of one or more other road users from the procured observations, and determining a reference behavior of the one or more other road users based on one or more features of the digital road map. The method further includes, in response to the determined actual behavior being consistent with the determined reference behavior, establishing that the digital road map correctly reproduces the actual circumstances visible from the at least one predefined pose at least with regard to the one or more features from which the reference behavior was determined.

Abstract: A method for determining, from a plurality of satellites, a position of a mobile object having a reception device configured to receive satellite signals, includes performing a measurement of a plurality of pseudo-distances between the reception device and the plurality of satellites using the satellite signals. The method further includes correcting a result of the measurement using a surroundings model of surroundings of the mobile object to produce at least one corrected pseudo-distance. The surroundings model is indicative of at least one reflection plane of satellite signals.

Abstract: A method provides and transmits surroundings models and/or sensor data between at least two vehicles having the same or different automation levels by way of at least one controller. A first vehicle determines sensor data of its surroundings and creates a surroundings model for its own use. The created surroundings model and/or the sensor data of the first vehicle are transmitted for use to at least one second vehicle via a communication connection.
