Abstract: The invention provides a method for checking a semiconductor switch for a fault, wherein the semiconductor switch is driven with a PWM signal with a variable duty cycle. To the benefit of determining faults on the semiconductor switch reliably and cost-effectively, it is provided that if the semiconductor switch is operated with a duty cycle of 100% or 0%, the current measurement of the overall system is evaluated, while if the semiconductor switch is operated with a duty cycle of between 0% and 100%, the generated voltage pulses across the semiconductor switch are evaluated.

Abstract: A vehicle shell assembly, having a plate-like plastic body having an outside and an inside. A lighting unit is provided which is disposed on the inside and is configured to be switched between an active state and a passive state; the inside of the plastic body is provided with an opaque light-impermeable coating which has at least one gap; and the plastic body may have of a translucent material so that the gap is covered by the plastic body to the outside when the lighting unit is in the passive state and defines a light pattern which is visible from the outside when the lighting unit is in the active state.

Abstract: A method for producing a vehicle composite component with a layer structure having a core layer in a molding tool, the core layer being formed with regions of different thickness is provided. Steps for this method may include placing a cover layer, in particular a preformed cover layer, which in particular forms an outer skin of the vehicle composite component, onto a mold base plate of the open molding tool; introducing a first fiber layer, which is impregnated with PU resin and has not been subjected to forming, between the cover layer and a first mold counterplate of the open molding tool; closing the molding tool and compression molding the first fiber layer, which is impregnated with PU resin, against the cover layer, as a result of which a preform with a first support layer containing the first fiber layer is formed and hardened while supplying heat.

Abstract: A drive device for a roof component of a vehicle, such as, for instance, a sliding roof and a solar protection roller blind, may have an electric motor which for activating the roof component interacts with a gearbox. The electric motor here is an external rotor electric motor of a flat construction mode which is aligned so as to be parallel to the installation height of the drive device in a vehicle roof and which has a wheel-shaped external rotor which by way of a toothing provided on the external circumference of the latter engages with the gearbox.
