Abstract: The disclosure relates to a method for operating a sensor circuit in a motor vehicle, wherein a processor in the sensor circuit receives a reflection signal from an environment of the motor vehicle by way of an environmental sensor and ascertains from the reflection signal a particular detection point, which describes a relative position of a reflection event with respect to the motor vehicle. The disclosure involves the processor using pattern data to establish a surface region in the environment and a category of the surface region and checking for the detection point whether it lies in the surface region, and the detection point which lies in a surface region is categorized according to the pattern data of the surface region and the detection point is filtered according to its categorization by way of a filtering action for trajectory planning of a driving trajectory of the motor vehicle.

Abstract: A method for localizing a motor vehicle in an environment during a driving operation comprises, by a processor circuit in repeated estimation cycles, receiving sensor data of landmarks of the environment from an environment sensor, and ascertaining a respective estimated position of the motor vehicle from feature data, which are formed of map data of a map region of the environment and of the sensor data, using an estimation module. A movement path is estimated from the positions of multiple of the estimation cycles using a statistical observer model, and the observer model, during the formation of the movement path, models measurement noise contained in the position data as a covariance matrix of position coordinates of the position data, with matrix values of the covariance matrix being ascertained by the estimation module as a function of the sensor data and the map data.

Abstract: A method for operating a driving dynamics system facility of a motor vehicle includes using a control device that provides driving style data while driving, and establishes a driver type for the driver based on this. The control device establishes a road category of a roadway. With the aid of the driver type and the road category, the control device establishes a current driving context, and carries out a preliminary selection of at least one driving mode. With the aid of driver monitoring data, the control device establishes a current emotion of the driver, and selects with the aid of this one of the preselected driving modes. The control device generates a switching signal for switching to the driving mode being activated and configures accordingly the at least two motor vehicle systems. The driving mode can be adapted with the aid of further driver monitoring data, describing a reaction of the driver to the activated driving mode.

Abstract: According to a method for self-localization of a vehicle, a first pose of the vehicle is determined in a map coordinates system, based on environment sensor data representing an environment of the vehicle, a landmark is detected in the environment, a position of the landmark is determined in the map coordinates system and a second pose of the vehicle is determined in the map coordinates system dependent on the position of the landmark. An assignment instruction is consulted, matching up the first pose with at last one preferred sensor type or at least one dominant landmark type. Depending on the assignment instruction, a first environment sensor system is activated and a second environment sensor system is deactivated, whereupon the environment sensor data are generated by means of the first environment sensor system.
