Abstract: A method for determining navigation data by way of a GNSS localization device is disclosed. The method includes a) obtaining GNSS satellite signals from GNSS satellites; b) receiving at least two alternative GNSS correction data from at least two different correction data sources c) analyzing the alternative GNSS correction data and determining the validated correction data; and d) determining navigation data from received GNSS satellite signals and validated correction data.

Abstract: The disclosure concerns a method for GNSS-based location of a vehicle having a GNSS location device in view of integrity information provided in relation to GNSS correction data, comprising at least the following steps: (a) receiving GNSS correction data for correcting delay measurements for GNSS-based location from a GNSS correction data provision system, (b) receiving at least one piece of integrity information about the reliability of the GNSS correction data from the GNSS correction data provision system, (c) evaluating the at least one piece of integrity information about the reliability of the GNSS correction data that was received in step (b), and (d) influencing GNSS-based location of the vehicle on the basis of the evaluation from step (c).

Abstract: In order to perform a simple plausibility check of a rollover decision which is as reliable as possible, an arrangement is provided which signal plausibility of the rollover decision if an acceleration measured in the direction of the vertical axis of the vehicle is either above a preset upper threshold or below a preset lower threshold, or if the acceleration measured in the direction of the vertical axis is between the two thresholds, but an acceleration measured in the direction of the transverse axis of the motor vehicle simultaneously exceeds a threshold which depends on the acceleration measured in the direction of the vertical axis.

Abstract: The system is intended to have the ability to differentiate between various characteristic driving maneuvers, so that a special triggering algorithm of restraint devices can be initiated for each class of driving maneuvers. This system has an acceleration sensor that measures the acceleration of the vehicle in the direction of its vertical axis. A classifier is provided which, when the measured acceleration is above a threshold of 1 g, decides on a driving maneuver in which the vehicle lifts upward on one side, as when driving on a ramp. If the measured acceleration is between 0 g and 1 g, then the classifier decides on a driving maneuver during which the vehicle tips downward on one side, as when driving on a slope.

Abstract: The arrangement is to allow timely rollover recognition in the event of tipping over an embankment. For this purpose, the arrangement determines a predictive value of the yaw rate of the vehicle after a fictitious impact of the wheels on one longitudinal side of the vehicle against the ground from a yaw rate prevailing prior to the fictitious impact, the momentum of the vehicle in the direction of its vertical axis, and the angular momentum of the center of gravity of the vehicle prior to the fictitious impact. In addition, using the currently measured angle of inclination of the vehicle, it determines a critical yaw rate of the vehicle about its longitudinal axis instantaneously measured by the arrangement, which would be required to cause the vehicle to roll over. A conclusion is drawn about an imminent rollover if the predictive value of the yaw rate exceeds the critical yaw rate.
