  • Patent number: 10965491
    Abstract: System (10) for energy and/or data transmission in a vehicle (15), with at least one node element (120) for the networked connection of at least two electric components (30) of the vehicle (15), so that different connecting paths are provided, and the transmission of energy and/or data occurs in an adaptable manner via at least one of the connecting paths.

  • Publication number: 20190340090
    Abstract: A control system for a motor vehicle having a first control unit for controlling a first function of the motor vehicle, a second control unit for controlling a second function of the motor vehicle and a backup control unit. At least the first or the second control unit is connected in a signal-transmitting manner with the backup control unit. In order to ensure the proper execution of functions of a motor vehicle controlled by the control units with the least possible additional overhead, even with a faulty control unit, the backup control unit is configurable in response to the input of an error signal from the first or the second control unit such that the function of the motor vehicle corresponding to the faulty control unit is be controlled via the backup control unit.

  • Publication number: 20090018767
    Abstract: A method for determining the geometry of a route section, using route points representing information about the route section, wherein route section data between at least three adjacent route point s are calculated, for determining a maximum possible speed for a vehicle traveling along the route section, is characterized in that a check is made to ascertain whether two adjacent route points f all below respectively predeterminable distances from one another and in the affirmative route section data through the se route points are calculated as a) straight line if the route points are arranged in a straight strip of predeterminable width, or b) arc of a circle if the route points are arranged in a constantly curved strip of predeterminable width and the tangent to the, in the direction of travel, first one of the route points is essentially located on a direction vector of the vehicle, or c) clothoid if the route points are arranged in a progressively curved strip of predeterminable width, wherein the geometry

  • Publication number: 20080077295
    Abstract: A system and a method for directionally stabilizing a vehicle with the aid of a steering system used for influencing a steering angle of the vehicle steered wheels and a stabilizing system which controls the steering system for increasing the vehicle directional stability is provided. The stabilizing system is characterized in that the stabilizing system controls the steering system according to the lateral force factor of at least one steered wheel for defining the steering angle stabilizing the vehicle, wherein the stabilizing system adjusts the slip angle of the steered wheels in such a way that the lateral force factor does not substantially exceed the maximum range thereof.

  • Patent number: 7336805
    Abstract: Many day-to-day driving situations require that an operator of a motor vehicle guide the motor vehicle along a specific course and bring the vehicle to a stop at a specific location, for example in a parking bay or at a loading platform. To assist a vehicle operator in such situations, a method and a suitable device for implementing this method, include detecting the potential target objects in the image data of an image sensor and identifying the potential target objects as potential destinations in a multi-stage exclusionary method, whereupon a trajectory describing an optimized travel path is computed at least in relation to the most proximate destination. By using the multi-stage exclusionary method according to the present invention, it is possible to reliably identify potential destinations in complex image scenarios solely on the basis of their geometric form, even when the destinations have not been encoded by specific symbols.

  • Patent number: 7237790
    Abstract: A system for coupling a trailer (2) to a motor vehicle (1), in particular a trailer (2) to a motor tractor (1), is provided with an image sensor (5), which is located in the coupling area. The coupling process involves connecting a trailer coupler (4) of the motor vehicle (1) and a tow bar (3) of the trailer (2), which is detected by an image sensor (5) detecting a movement of a locking element (8) associated with the trailer coupling (4). Thereupon a process of braking of the motor vehicle (1) is initiated.

  • Patent number: 7204504
    Abstract: In the case of a method for hitching a trailer (2) to a motor vehicle (1), in particular a semitrailer to a semitrailer towing machine, an image sensor (5) is provided which is arranged in a hitching region (6) in such a manner that image data of the hitching region (6) are recorded. During the approach of the motor vehicle (1) to the trailer (2), stored model data of the hitching region (6) of the trailer (2) are segmented in the image data recorded by the image sensor (5) and are in each case placed in the correct position in the image data. A target zone (9) for the hitching is determined therefrom. The arrangement of the target zone (9) in the image data is used as a measurement for a steering operation of the motor vehicle (1) during hitching.
