Abstract: A method for indicating the travel direction of a motor vehicle includes: sensing that a travel-direction indicating device of the motor vehicle is actuated, wherein the travel-direction indicating device, when actuated, causes the output of a first acoustic signal at a first volume in order to accordingly inform an occupant of the motor vehicle, such as, in particular, the driver of the motor vehicle. For the user-friendly provision of a less distracting method for indicating the travel direction of a motor vehicle, the method includes: sensing, by way of a vehicle-movement sensing device, that the motor vehicle has come to a standstill from a moving state, more particularly a rolling state, and, during the standstill of the motor vehicle, the travel-direction indicating device causes a second acoustic signal to be output instead of the first acoustic signal, the second acoustic signal differing from the first acoustic signal by virtue of the lower volume.

Abstract: The technology disclosed by the invention relates to a pressure vessel system for a motor vehicle for storing fuel, comprising a plurality of pressure vessels (100) that are combined to a pressure vessel assembly (10), the pressure vessels (100), when mounted, being arranged substantially in parallel relative to each other, and the pressure vessels (100) being fluidically interconnected via a common fuel line (200).

Abstract: A method produces a pressure vessel having at least one fiber-reinforced layer. The reinforcing fibers of the fiber-reinforced layer are formed of at least one endless fiber. The modulus of elasticity of the at least one endless fiber is varied.

Abstract: A pressure vessel for storing fuel is provided. The pressure vessel includes a liner for storing fuel, a fiber-reinforced layer which surrounds the liner at least in regions, and at least one load ring. Connecting pins project from the surface of the load ring, and the connecting pins protrude out of the fiber-reinforced layer. A motor vehicle including such a pressure vessel and a production method for the pressure vessel are also provided.
