Abstract: A method for determining an ego-motion of a vehicle is described, which is carried out in driver assistance systems, particularly in parking assistance systems. The method involves: taking a sequence of images, successive in time of a vehicle surroundings by a vehicle camera; determining, based on the image sequence, at least one motion flow with regard to an object in the vehicle surroundings; and determining the ego-motion of the vehicle based on the at least one motion flow.

Abstract: A method for setting the fill level when filling a cavity system, in particular a cavity system in vehicle seat that exhibits one or more pressure chambers or bubbles for lumbar adjustments. With the method, a fill level set by the user is measured and a value representative thereof is stored. The value representative for the fill level is determined from a curve line that is characteristic for the respective cavity system.

Abstract: Methods in a driver assistance system of a vehicle for detecting wetness on a road surface as well as a corresponding driver assistance system having a rearview camera are described. The method may include the following: recording an image of an area located behind the rear end of the vehicle, using the rearview camera; evaluating the recorded image for the presence of a spray trail caused by the vehicle; and selectively outputting, based on the evaluation, a wetness signal for triggering an automatic response by the driver assistance system to the wet road surface.

Abstract: An adjusting device (10) is provided for a vehicle subassembly to be adjusted. The adjusting device has an adjusting motor which, via an adjusting mechanism, drives a toothed rocker (12) assigned to the vehicle subassembly to be adjusted. The adjusting mechanism structurally reinforces the vehicle subassembly to be adjusted, and an adjusting worm (20) of the structurally reinforcing adjusting mechanism acts directly on the toothed rocker (12).

Abstract: Methods for distance determination, as are used, for example, in parking assistance systems are described. In a vehicle at standstill, the method involves detecting a first predefined event that occurs in connection with a pitching motion of the vehicle, and based on the detection of the first event, activating the camera in order to record a first and a second image of the vehicular environment and include a time reference to the pitching motion. The method also includes processing the first and the second image in order to determine a distance to the object from a displacement of the object in the field of view of the camera that has taken place between the points in time of the recording of the first and second image in response to the pitching motion.

Abstract: A method for determining the position of another road user includes the following steps: determining the position of a road user with the aid of a position detection unit; estimating a distance of the road user to the other road user with the aid of a distance sensor; and determining the position of the other road user on the basis of the determined position of the road user, the estimated distance, and a road map, the other road user being assumed to be located in a road area predefined by the road map.

Abstract: A backrest of a motor vehicle seat (1) has a head restraint (4) that can be adjusted in height with the aid of a guide. To reduce the production costs of the backrest, the guide for the height adjustment of the head restraint (4) is integrated in the head restraint (4).

Abstract: A circuit arrangement for supplying power to control devices in motor vehicles, having a first power supply line, a first ground line, a second power supply line and a second ground line, characterized in that the first ground line and the second ground line can be connected by a controllable switch, and in that a logic circuit closes the switch when the first ground line is faulty or interrupted.

Abstract: An adjustable vehicle seat (1) has an inclinable seat part (2). Front and rear bearings (7, 5) have upper ends pivotably connected to front and rear areas of the seat part (2) and having lower ends mounted pivotably in bearings (7, 5) in floor rails (10). The front bearings (7) have an adjustable length for changing an inclination of the seat part (2). First additional links (11) are mounted pivotably about a first axis (G2) in the seat part (2). Second additional links (12) have lower ends mounted pivotably in the rails (10) and upper parts connected pivotably to the first additional link (11) at a second axis (G6) spaced from the first axis (G2). An inclinable backrest (3) is mounted pivotably in the first additional link (11).
