  • Patent number: 10303177
    Abstract: A method for operating a control device for the autonomous guidance of a motor vehicle, wherein a nominal speed is predetermined as a driving speed to be set by the control device and another vehicle driving in front more slowly than the nominal speed is detected by a detection device of the control device, wherein a speed difference of a driving speed of the other vehicle with respect to the nominal speed is greater than zero but smaller than a predetermined maximum value. In this case, an accumulator value is set to a starting value and a current speed value of the speed difference is detected and depending on the speed value, an advantage value is formed and the advantage value is added to the accumulator value. If the accumulator value meets a predetermined overtaking criterion, an overtaking signal is generated for allowing an overtaking maneuver.

  • Publication number: 20190131636
    Abstract: The invention relates to a bipolar plate for a fuel cell, comprising an anode plate with anode gas channels and a cathode plate with cathode gas channels, said plates having an active region and supply regions and being arranged one over the other such that the gas channels form coolant channels. The aim of the invention is to improve such a bipolar plate such that the flow conditions of reactants and coolant in the bipolar plate are optimized. This is achieved in that the height and/or the width of the cathode gas channels increase(s) from a first side of the active region to a second side of the active region, and the height and/or the width of the anode gas channels decrease(s) from the first side of the active region to the second side of the active region, wherein the cross-sectional area and/or the hydraulic diameter of the cathode gas channels increases, and the cross-sectional area and/or the hydraulic diameter of the anode gas channels decreases.
