  • Transmission Device for a Motor Vehicle
    Publication number: 20100044183
    Abstract: A motor vehicle transmission device is described. The transmission has an actuating unit, used for canceling a tooth-on-tooth position of coupling elements, wherein the actuating unit actuates a transmission brake when the tooth-on-tooth position is detected. The transmission also has a second actuating unit for actuating a disconnect clutch, the second actuating unit actuating the disconnect clutch when the tooth-on-tooth position is detected. The actuating unit for actuating the transmission brake and the second actuating unit for actuating the disconnect clutch are actuated in coordination with one another, in order to cancel the tooth-on-tooth position.

  • Device and Method for Influencing the Spring Force Characteristic of an Active Chassis of a Motor Vehicle
    Publication number: 20100042292
    Abstract: A device and a method for influencing the spring force characteristic of an active chassis of a motor vehicle are provided. A wheel spring device is arranged between a vehicle body and a wheel carrier of the motor vehicle. The spring force characteristic of the wheel spring device can be modified by controlling an actuating device. A sensor detects a prediction variable representing the vertical profile of a route ahead in the direction of travel of the motor vehicle. A control device controls the actuating device as a function of the detected prediction variable in such a way that the spring force characteristic of the wheel spring device is adapted in a predictive fashion to the course of the sensed vertical profile of the route ahead in the direction of travel of the motor vehicle.

  • Method for the analysis of correspondences in image data sets
    Patent number: 7664314
    Abstract: Processing of image data relating to moving scenarios, especially for recognizing and tracking objects located therein, requires identifying corresponding pixels or image areas in the individual successive image data sets. Likewise, processing of stereo images requires identifying the data areas which correspond to each other in two images that are recorded substantially at the same time from different angles of vision. According to the novel method of analyzing correspondences in image data sets, the image data sets that are to be compared are transformed using a signature operator such that a signature string is calculated for each pixel and is stored in a signature table allocated to the individual image data sets along with the pixel coordinates in a first step.

  • Method and Apparatus for Supplying Input Gases to a Fuel Cell Stack
    Publication number: 20100035100
    Abstract: A fuel supply system for a fuel cell stack includes a cathode gas supply line for supplying an oxidant to the cathode input of the fuel cell stack and an anode gas supply line for supplying fuel to the anode input of the fuel cell stack. An anode gas recirculation line recirculates partially used anode gas from the anode output to the anode input while a purge line may be connected for conducting away the partially used anode gas, as a purge gas from the anode gas recirculation line into the cathode gas supply line. The supply system also includes a conditioning arrangement disposed upstream of the cathode input. The conditioning arrangement is designed to a) mix a partial flow of the oxidant with the purge gas in a mixing station, b) compress accelerate, and/or heat the partial flow or the mixed flow, and c) conduct the mixed flow into the cathode gas supply line.
