Abstract: A device for controlling an interior lighting system of a vehicle to produce ambient lighting and/or reading lighting involves the interior lighting system having an array of a plurality of light sources. The device includes a control unit, by means of which the light sources of the array can be individually controlled in order to produce the ambient lighting and/or the reading lighting, and an input unit that can be connected to the control unit. The input unit has a touch-sensitive screen for inputting a current set of control information for the control unit. The control unit controls the light sources on the basis of the current set of control information. Furthermore, the input unit, on the basis of the current set of control information, displays associated ambient lighting and/or reading lighting for an illuminable region in the vehicle interior on the screen.

Abstract: An air filter for a ventilation device of a motor vehicle is disclosed. The air filter has a planar extension along which the air filter is able to be inserted into a flow area of the ventilation device transversely relative to a flow direction and has a filter medium arranged along its planar extension. The filter medium is bordered at least in certain regions by at least one frame wall. The frame wall has at least one section which is able to be brought into engagement with guide elements of the ventilation device in order to guide the air filter during insertion into the flow area.

Abstract: Methods and systems are provided for cold-start of fuel cell stack in fuel cell vehicles. In one example, a method may include in response to cold-start of fuel cell vehicle, limiting the load drawn from the fuel cell stack. In addition, a coolant pump may be operated at a higher rate through a bypass loop to get heat quickly to the fuel cell stack to increase the solubility of water in the fuel cell stack to prevent ice formation. The net effect is that the fuel cell stack is then operated within the ice capacity of the membrane, and start-up at lower temperatures is possible without experiencing an intermittent performance drop due to active area freezing. Once the fuel cell stack is sufficiently warmed up, the coolant pump rate and fuel cell stack may be adjusted according to the demand.
