Abstract: A battery assembly includes a cell group having at least one battery cell which has a releasable cell degassing opening, a carrier plate having a first carrier side, a second carrier side, and a passage area opposite to the releasable cell degassing opening as part of a degassing area of the carrier plate, a protective plate arranged below the carrier plate and facing toward the second carrier side, and a first degassing chamber between the protective plate and the carrier plate. A sealing layer is arranged on the second carrier side covering the degassing area and separates it from the first degassing chamber. A second degassing chamber is formed between the degassing area and the sealing layer to temporarily fluidically separate from the first degassing chamber in case of degassing.

Abstract: A method for operating a self-driving vehicle is provided. The method includes specifying a lateral dynamics requirement for controlling the lateral dynamics of the self-driving vehicle along a route. The lateral dynamics requirement is communicated to a steering control device for controlling steering kinematics of the self-driving vehicle. The method checks whether the communicated lateral dynamics requirement satisfies a lateral dynamics criterion for the operation of the self-driving vehicle, and communicates a brake command to stop the self-driving vehicle depending on a checking result resulting from the checking step.

Abstract: A road vehicle with a vehicle frame and a rear axle connected to the vehicle frame is provided with an ambient air purification device with filter elements for removing dust, particulate matter, and gases from ambient air. The ambient air purification device is arranged transverse to a longitudinal vehicle axis in an exterior region of the road vehicle at a vehicle rear of the road vehicle in an underfloor region such that at least the filter elements are arranged behind the rear axle of the road vehicle in a travel direction of the road vehicle. The ambient air purification device is received in an installation space of the vehicle frame. The ambient air purification device is flowed through in longitudinal vehicle direction. A free outflow zone of the ambient air purification device is arranged, in travel direction of the road vehicle, behind the ambient air purification device.

Abstract: A brake dust particle filter for a disc brake assembly with brake disc and brake caliper has a filter housing with opposed first and second side walls, a circumferential wall section extending at least partially circumferentially, and an end wall. The first and second side walls are connected to each other by the circumferential wall section and/or by the end wall. A filter housing interior extends from a side of the filter housing facing the brake caliper along the first and second side walls and the circumferential wall section to the end wall. An air-permeable filter wall arranged in the filter housing interior has a filter wall circumferential section that is radially spaced from the circumferential wall section and divides the filter housing interior into a raw air side and a clean air side. The clean air side extends between filter wall circumferential section and first circumferential wall section.

Abstract: An environmental air cleaning device for a road vehicle removes dust, particulate matter, and/or gases from environmental air. The environmental air cleaning device has one or more filter elements. The environmental air cleaning device is provided with a mounting device that rigidly couples to a vehicle-side mounting device for roof loads. A road vehicle with such an environmental air cleaning device is provided.

Abstract: A tray gripper may be attached to a gripper arm of a tray sealing machine. For this purpose, the tray gripper is moved to a pre-assembly position by hooking the tray gripper onto the gripper arm. In addition, an eccentric is operated for exerting a clamping force upon the tray gripper that is disposed in the pre-assembly position, so that an attachment structure of the tray gripper is tensioned against an abutment structure of the gripper arm.
