  • Publication number: 20210009107
    Abstract: A method for operating a driver assistance system of a vehicle involves, for determining a position of the vehicle in a digital environment map, detecting environment data for the vehicle using an on-board sensor system and matched with map data stored in the environment map. A position of the vehicle in a real environment is determined using position data of the vehicle from an on-board satellite receiver. Accuracy of the determined position of the vehicle is determined based on the position data and environment data matched with the environment data. Accuracy is predicted with which the position of the vehicle in the environment map can be determined for a predetermined section of road ahead of the vehicle. Fully automated operation of the vehicle is enabled when the determined accuracy and the predicted accuracy for the predetermined section of road ahead of the vehicle are greater than at least one accuracy threshold.

  • Patent number: 10886549
    Abstract: Simplified methods are disclosed for preparing a catalyst coated membrane that is reinforced with a porous polymer sheet (e.g. an expanded polymer sheet) for use in solid polymer electrolyte fuel cells. The methods involve forming a solid polymer electrolyte membrane by coating membrane ionomer solution onto a first catalyst layer and then applying the porous polymer sheet to the membrane ionomer solution coating, while it is still wet, such that the membrane ionomer solution only partially fills the pores of the porous polymer sheet. A second catalyst ink is then applied which fills the remaining pores of the porous polymer sheet. Not only are such methods simpler than many conventional methods, but surprisingly this can result in a marked improvement in fuel cell performance characteristics.

  • Publication number: 20200391580
    Abstract: A motor vehicle has an interior which is accessible via a door opening which can be closed by a door and which can be enlarged from a driving position into a parking position by displacing a vehicle roof region delimiting the door opening. The vehicle roof region can be moved along as part of the at least substantially entire vehicle roof which can be displaced between the driving position and the parking position relative to a lower vehicle body part. The door is mounted on the displaceable vehicle roof.
