摘要： A device estimates an actual trajectory of a vehicle. The device is designed to determine a sequence of measured position values over a corresponding sequence of times by use of a position sensor. The device is further designed to determine a sequence of odometry values on the basis of sensor data from one or more vehicle sensors. The device is also designed to determine, as an estimation of the actual trajectory of the vehicle, a sequence of estimated pose values for the sequence of times and a systematic position offset for the sequence of measured position values so that an optimization criterion is improved, in particular is optimized at least locally.

摘要： A method determines a weather area for a motor vehicle, with which a sensor system and a communications interface are associated, which are coupled to one another via signals. The method includes: receiving data including geographical information in the form of a map; and creating a grid by dividing the received data into a plurality of adjacent grid cells. The method also includes: providing a measurement signal of the sensor system, representing a location-related local weather situation in one of the grid cells; and determining a local weather area for the respective grid cell according to the provided measurement signal.

摘要： A road having a lane includes a first and a second segment having no branch-offs, and a third segment, which lies between the first and second segments and in the range of which the road forms a single-level traffic junction with another road. A method for determining the course of the lane includes steps of determining driving trajectories of a plurality of motor vehicles in the lane in the range of the first and/or the second segment; determining the course of the lane in the range of the first and second segments on the basis of the driving trajectories; determining a probable driving trajectory of the motor vehicles in the range of the third segment on the basis of the determined course in the first and second segments; and determining the course of the lane in the range of the third segment.

摘要： A method for determining a road construction site for a motor vehicle, with which a sensor system and a communications interface are associated, which includes: providing a first measurement signal of the sensor system, representing a sign of a first speed limit for the motor vehicle and determining a location-related actual speed identification according to the first measurement signal. The method also includes: providing mapped data including information relating to a location-related local speed limit and detecting a road construction site according to the actual speed identification and the mapped data.
