Abstract: A computer-implemented method estimates a vehicle position. The method provides a first position estimate based on position information from at least one first source, wherein the first position estimate is assigned a first bias value and a first statistical variance; provides a second position estimate based on position information from at least one second source; determines a third bias value and a third statistical variance, wherein the third bias value and the third statistical variance are assigned to a third position estimate which results from a combination of the first position estimate and the second position estimate; and evaluates the first position estimate and the third position estimate on the basis of a quality criterion which takes into account the bias value assigned to each position estimate and the statistical variance assigned to each position estimate.

Abstract: A method for determining the validity of an estimated position of a vehicle includes receiving the estimated position; receiving sensor information relating to a vehicle environment; detecting a number of first features in the digital map and a number of second features in the sensor information, wherein the features indicate at least one object beside a road; grouping the first features into a number of first feature groups and grouping the second features into a number of second feature groups; rejecting first and/or second feature groups; assigning at least some of the first feature groups which have not been rejected to a particular second feature group which has not been rejected; and determining the validity of the estimated position based on a comparison of positions of a number of the first feature groups which have not been rejected with positions of the respectively assigned second feature groups.

Abstract: A method for operating a driver assistance system of a vehicle includes the steps of: checking whether there is a motorway exit or roadworks on a first side of the vehicle; checking whether an environment sensor system of the vehicle detects a lane marking that bounds a lane of the vehicle on a second side, which is opposite the first side; if the result of the checking is that there is a motorway exit or roadworks on the first side of the vehicle and that the environment sensor system detects the lane marking, operating a lane-keeping function of the driver assistance system; and if the result of the checking is that there is a motorway exit or roadworks on the first side of the vehicle and that the environment sensor system does not detect the lane marking, triggering a takeover request to a driver of the vehicle.

Abstract: A method for controlling a first vehicle, travelling on a road, that has a second vehicle travelling ahead of it, includes the steps of: scanning the second vehicle from the first vehicle by use of multiple sensors; providing individual determinations, each on the basis of scans by only one of the sensors, concerning whether the first and the second vehicle are travelling in the same lane of the road, wherein each sensor has an associated determination certainty; and providing a collision warning if a product of the determination certainties is below a predetermined threshold value.

Abstract: A method for securing a geographic position of a vehicle includes scanning multiple information sources, which each provide items of information which indicate the position of the vehicle; determining individual positions on the basis of each of items of information of one of the information sources and items of surroundings information in the region of a position hypothesis; validating items of information, the associated individual position of which deviates by not more than a predetermined amount from the position hypothesis; determining the position of the vehicle on the basis of the validated items of information, wherein a change of a quality of the items of surroundings information is determined; and, on the basis of the change, determining a probability at which the determined position deviates by more than the predetermined amount from an actual position.

Abstract: A method is disclosed for identifying an appropriate parking space for a motor and a route leading thereto for a motor vehicle having a navigation system, wherein at least one collision-free route is calculated on the basis of at least one piece of information that is related to a search for a parking space and that is requested from at least one external server, which manages at least one parking lot having at least one parking space, before the motor vehicle reaches the parking lot. A motor vehicle with a navigation system and an external server, for execution of the method, are also disclosed.

Abstract: A method for operating a navigation system including a vehicle and a computing device outside the vehicle is described. A navigation device on-board the vehicle determines, from route network data transmitted by the computing device and describing route segments of a route network, a route segment sequence. The route segment sequence includes at least one route segment and is used to reach a target position from a start position. The navigation device verifies the traversability of the route segment sequence for the vehicle, taking into account route segment information transmitted by the computing device upon a request of the navigation device, and determines a navigation route derived from a route segment sequence which has been verified to be traversable.

Abstract: A motor vehicle has a control device to control automated longitudinal and/or transverse guidance of the motor vehicle within the scope of a specific driving maneuver. The motor vehicle also has an operator control element to communicate with the control device and to transfer control information, relating to the at least partially automated longitudinal and/or transverse guidance, to the control device. The control device is configured in such a way that activation or deactivation of the longitudinal and/or transverse guidance can be controlled by means of an operator-side first operator-control action at the operator-control element, and at least one driving parameter which influences the longitudinal and/or transverse guidance of the motor vehicle, controlled by the control device, can be modified by means of an additional operator-side, second operator-control action at the operator-control element, which second operator-control action is in particular different from the first operator-control action.
