  • Patent number: 11370484
    Abstract: A method for steering a vehicle that comprises a steering system with a steering wheel and a front axle as well as a rear axle with wheels, wherein it is provided that a direction of the vehicle is adjusted manually by a driver of the vehicle by adjustment of a steering wheel angle of the steering wheel, as a result of which, for the wheels of at least one of the axles, a steering angle is adjusted, which is obtained from the steering wheel angle plus a superposition angle, wherein, through an automatically adjustable steering ratio for the wheels of at least one of the axles, a ratio of the steering wheel angle to the steering angle for the wheels is set, wherein the vehicle travels into a curve on a circular path with a radius at a speed with a first value, wherein a steering wheel angle is adjusted by the driver.

  • Patent number: 11059515
    Abstract: A method for control of a rear-axle steering of a motor vehicle. A steering angle of wheels of a rear axle is set. Upon reaching a predetermined lateral acceleration of the motor vehicle, the steering angle and/or the gradient of the steering angle of the wheels of the rear axle is limited as a function of a coefficient of friction of a roadway surface on which the motor vehicle is moving.

  • Patent number: 8876732
    Abstract: Sampling device for obtaining a sample of an analyte, comprising a feed line (30) and a discharge line (40) as well as an analyte feed chamber (13) in fluidic connection between the feed line and the discharge line, the analyte feed chamber having an opening (14) which is provided with an analyte-permeable membrane (15) to allow the analyte to pass through from a region outside the analyte feed chamber into the analyte feed chamber, the surface area of the opening of the analyte feed chamber being at most 400 times the minimum cross-sectional surface area of the discharge line, more preferably at most 100 times and most preferably 50 to 80 times the minimum cross-sectional surface area of the discharge line. This device will reduce the dead time between the passage of the analyte through the membrane and the detection of said analyte at the sensor.
