  • Pem Fuel Cell with Charging Chamber
    Publication number: 20080220311
    Abstract: Proposed is a PEM fuel cell that comprises a separator plate assembly with a charging chamber, which is partitioned off by a partition wall and via charging spots has a fluid connection to an adjoining cathode chamber. The partition wall is designed so that the depths of the charging channels in the charging chamber and the depths of the distribution channels in the adjoining cathode chambers change in such a way that the quantity of oxidant that is charged at a charging spot from the charging chamber into the cathode chamber can be fixed in advance. As a result, the charging of oxidant, which has not been humidified or only slightly, into the cathode chamber can be improved with regard to the curve of the relative humidity along the cathode. Also proposed is a method for manufacturing a separator plate assembly suitable for a PEM fuel cell.

  • Method and Device for Actuating a Vehicle Occupant Protection Means
    Publication number: 20080221758
    Abstract: A method and apparatus for preventatively actuating a vehicle occupant protection system in a vehicle having a sensor system which acquires driving state data, and a reversible vehicle occupant protection means which can be triggered before the collision time and thus moved into an operative position. A control signal for triggering the vehicle occupant protection means is activated if at least one critical driving state is present, and is deactivated if the respective critical driving state ends and as a function of at least one further condition which represents at least one sensed controllable driving behavior. As a result, the vehicle occupant protection system is reset to its initial state.

  • Method and device for warning a driver of lane departure
    Patent number: 7424364
    Abstract: A method and device for warning a driver of lane departure, wherein a first analyzer is used to detect the vehicle's lane departure based on image data and/or vehicle data and/or driver activity. The driver then receives a warning as a function of the detection by the first analyzer. In addition, a second analyzer for evaluating the driving situation is provided, which either performs the evaluation of the driving situation after the detection and via which the warning is suppressed as a function of the evaluation, or which alternatively performs an evaluation of the driving situation before the detection and via which a detection of lane departure is suppressed as a function of the evaluation.

  • Switching arrangement for actuating lighting systems on a motor vehicle
    Patent number: 7417201
    Abstract: Future motor vehicles will require additional lighting means. Additional lighting means are required, above all, in conjunction with environmental sensors, especially sensors which are used in night vision systems. As a result of the generally increasing number of electric and electronic systems in motor vehicles, such systems must be easy to operate for the driver. The invention thus relates to a switching arrangement which enables a plurality of lighting systems to be ergonomically operated on one motor vehicle. Said switching arrangement comprises a single switch having a plurality of switching stages. In this way, all switching stages pertaining to different lighting systems are located in the same switching region, enabling the lighting systems to be operated in a simple and intuitive manner.

  • Method for operating an internal combustion engine comprising an exhaust gas purification system
    Patent number: 7418334
    Abstract: A method for operating an internal combustion engine having an exhaust gas purification system. Intake air throttling is carried out in order to raise an exhaust gas temperature in a low-load mode and in a traction mode. The amount of intake air throttling is determined as function of an expected load demand so that, with an expected unchanged or decreasing load demand, an increased or maximum possible intake air throttling is set. With an expected rising load demand, however, no or reduced intake air throttling is set, and the expected load demand is estimated based on operating and ambient parameters of the internal combustion engine.
