An upper bound is imposed on the final desired torque output by the control unit with a limiting torque dependent on the measured/manipulated variables of the accelerator pedal value sensor, when the detected vehicle speed lies below a starting limiting speed. | 12-24-2009 |
| 20090317690 | APPARATUS FOR HUMIDIFYING A GAS FLOW - In a device for humidifying a gas flow, an atomized liquid is combined with a gas flow in a spray chamber, and passed through a generally U-shaped gas flow passage having a first generally vertical part | 12-24-2009 |
| 20090306849 | SYSTEM FOR DIAGNOSIS OF MOTOR VEHICLES, AND FOR RECEPTION OF VEHICLES AT A REPAIR FACILITY - In a diagnostic system, messages which have occurred are collected and buffered with a short diagnostic test which is implemented in a control unit onboard the vehicle. The collected data are then transmitted into a memory area of the portable electronic driving authorization record, which therefore always contains the result of a short diagnostic test which has been carried out onboard. The result of this short diagnostic test is read out from the memory of the driving authorization record with a computer system in the customer reception of a servicing workshop, and is processed with a more wide-ranging diagnostic algorithm which builds on the result of the short diagnostic test. | 12-10-2009 |
| 20090302636 | Rear Window Arrangement for a Motor Vehicle - A rear window arrangement for a motor vehicle has an intrinsically rigid rear window which can be moved by means of a guide device between an upper position and a lowered position. A receiving space behind the passenger compartment is provided for the rear window within the motor vehicle. The rear window has a curvature in the vertical direction of the vehicle and can be moved along a curved movement track by means of the guide device. | 12-10-2009 |
| 20090301809 | Device for absorbing and reducing noise in the inside of a vehicle - A device for absorbing and reducing low-frequency airborne sound in the inside of a vehicle. At locations at which disturbing low-frequency airborne sound occurs, at least one orifice at which low-frequency airborne sound waves are braked, is formed in an adjacent boundary edge surface ( | 12-10-2009 |
| 20090301700 | Heat Exchanger Comprising Deep-Drawn Heat Exchanger Plates - In a method for producing a heat exchanger tube bundle for a heat exchanger of an electrochemical energy accumulators, heat exchanger channels and an intended profile are incorporated into material strips by deep drawing. A forward-flow distribution aperture is incorporated into a first such material strip from step b) (first heat exchanger plate), and return collecting apertures are incorporated into a second such material strip, forming first and the second heat exchanger plates. The latter are aligned in such a manner that webs of the two heat exchanger plates border each other, and the heat exchanger channels form heat exchanger tubes. The heat exchanger plates arranged in this manner are joined together to form a heat exchanger tube bundle. A corresponding pressure welding apparatus, a heat exchanger tube bundle, a heat exchanger module, a heat exchanger with two or more heat exchanger modules, and an electrochemical energy accumulator with a heat exchanger of this type are also disclosed. | 12-10-2009 |
| 20090301069 | Exhaust Gas Cleaning Component for Cleaning an Internal Combustion Engine Exhaust Gas - A component for cleaning the exhaust gas in an internal combustion engine has a carrier body with a plurality of flow ducts for the exhaust gas. At least some of the walls ( | 12-10-2009 |
| 20090298413 | Air Filter for a Ventilation System of a Motor Vehicle - An air filter for a ventilation system of a motor vehicle has a filter frame and a filter medium fastened in and surrounded by the filter frame. The air filter can be inserted along its two-dimensional extent into a receiving slot and is sealed, at least along the inserted regions of the filter frame, between the filter frame and walls of the insertion slot. To allow the filter to be installed in the ventilation system in as force-free and simple a manner as possible, the filter frame has, in the end side facing the insertion direction, at least one guide slot which is oriented in the insertion direction. | 12-03-2009 |
| 20090297036 | OBJECT DETECTION ON A PIXEL PLANE IN A DIGITAL IMAGE SEQUENCE - The invention relates to a method for detecting objects on a pixel plane. Said movable object detection is frequently possible only by tracking the pre-segmented objects or the parts thereof. in this relation, the spatially adjacent objects often provoke problems, in particular in the case when a camera system or more precisely an observer is movable. The inventive method consists in determining a two-dimensional position of the relevant pixels inside a first image and in determining an associated remote value for each relevant pixel. Said pixels are tracked and localized on two ore more successive images, wherein the two-dimensional position or the pixel offset and the associated remote value are again determined for each pixel. The position and movement of the relevant pixels are also determined with the aid of a suitable filter. Finally, the relevant pixels are combined into objects under predefined conditions with respect to the position, moving direction and motion ratio thereof. | 12-03-2009 |
| 20090295191 | Drive for Moving a Wind Deflector on a Cabriolet - A drive for moving a lamella of a wind deflector is provided. The drive includes at least one coupling mechanism by which the lamella can be adjusted from a non-use position into a use position and vice versa. The mechanism is articulatedly connected at one end to the lamella and at the other end to the roof frame. The coupling mechanism is designed as a crank-rocker mechanism which raises the lamella away from the roof frame into the use position, and lowers the lamella onto the roof frame into the non-use position, in a substantially parallel fashion. | 12-03-2009 |
