  • Method for optimizing a power requirement of a motor vehicle
    Patent number: 9725086
    Abstract: A method for optimizing a power requirement of a motor vehicle that includes a speed control system for a drive unit and a temperature control system for a cooling circuit of the drive unit. A first power requirement of the drive unit to be expected and a second power requirement of the cooling circuit to be expected are determined based on at least one route parameter. A driving strategy corresponding to the route parameter is initially selected, and the first power requirement corresponding to the driving strategy and the second power requirement corresponding to the driving strategy are determined. Based on the determined first and second power requirements, the driving strategy is then adjusted in such a way that an overall power requirement of the motor vehicle is minimized.

  • Method for operating a side wind assistant for a vehicle and side wind assistant for a vehicle
    Patent number: 9694810
    Abstract: A side wind assistant for a vehicle and a method for the operation of the side wind assistant involve detecting a side wind disturbance acting on the vehicle and reacting to the side wind disturbance by carrying out a side wind compensation intervention to at least partially compensate for the influence of the side wind disturbance, at least when an intervention threshold has been exceeded. The side wind assistant thus reacts to the side wind disturbance in a frequency selective manner in which the frequency selectivity is controlled depending on the side wind compensation or a state of the side wind assistant correlating with the side wind compensation intervention. In particular, the frequency selectivity is controlled depending on whether the side wind compensation intervention is carried out or not carried out, and depending on the duration of the side wind compensation intervention.

  • Method for operating a fuel cell stack for a fuel cell system, and fuel cell system
    Patent number: 9698437
    Abstract: A method for operating a fuel cell stack (10) for a fuel cell system, in particular of a vehicle, in which by reversing the flow direction (14, 16) of a coolant during a cooling operation, the coolant in the fuel cell stack (10) is initially conveyed in a first direction (14). The coolant is subsequently conveyed in a second direction (16) which is at least substantially opposite to the first direction (14). A time period, after the elapse of which the flow direction (14, 16) is reversed, is changed during the cooling operation. In addition, a distance at which a coolant volume is situated from a heat source (12) that is present in the fuel cell stack (10) may be changed during the cooling operation. The invention further relates to a fuel cell system.

  • Method for determining a target curve incline of a motor vehicle during traveling of a curved roadway section
    Patent number: 9694812
    Abstract: A method and device for determining a target curve incline of a motor vehicle during traveling of a curved roadway section is disclosed. A momentary transverse acceleration of the motor vehicle is determined depending on a momentary speed of the motor vehicle and a momentary roadway curvature of the curved roadway section determined by an optical detection system. A momentary target curve incline for the motor vehicle is calculated from the determined momentary transverse acceleration. A modified momentary target curve incline is calculated by weighting of the calculated target curve incline with a speed-dependent target curve incline weighting factor. The momentary roadway curvature is determined by additionally using a vehicle navigation system of the motor vehicle.

  • Method for Starting the Normal Operation
    Publication number: 20170187055
    Abstract: A method for starting the normal operation of an electrical system with a fuel cell and a transducer from a stop mode is disclosed. The transducer absorbs the electrical power of the fuel cell, in which at least one reactant supply of the fuel cell was interrupted, where the interrupted reactant supply is resumed from a restart signal, and where a fuel cell voltage is prescribed and then regulated by the transducer. The prescribed fuel cell voltage is prescribed in a way that an electrical unloaded fuel cell supplied with reactants will exceed the prescribed fuel cell voltage in every case, and the current of the transducer necessary for maintaining the prescribed fuel cell voltage is measured, where the normal operation is released as of a prescribed current necessary to that effect.
