Abstract: A method for operating a particle filter that filters particles contained in the exhaust of motor vehicle combustion engines. A conditioning step is performed such that the separation efficiency of the particle filter for particles is increased relative to the value existing in the new condition.
Abstract: A method for controlling an electromechanical transmission includes monitoring a current hydraulic circuit oil temperature, monitoring a current state of flow management valves, monitoring a command for cooling of electric machines, monitoring a desired transmission operating range state, utilizing a state machine to determine a sequence for controlling positions of the flow management valves to achieve the desired transmission operating range state based upon the monitored properties.

Abstract: A method for improving drivability of the powertrain system having an accelerator control includes determining a first transmission input speed having an associated first power loss and operating said transmission using said first transmission input speed. An operational parameter relating to said accelerator control is determined and a second transmission input speed responsive to said operational parameter and having an associated second power loss is determined. The value of at least one of said first and second power loss is biased based on said operational parameter. The first power loss is compared to said second power loss subsequent to the biasing. A third transmission input speed is determined and the transmission is operated using the third transmission input speed.

Abstract: A restraint system having support elements can be transferred from a storage position to a restraint position. Flexible casing elements are disposed between the support elements and have air flow openings, such that the support elements having the flexible casing elements enclose a restraint volume in the restraint position. A resistance element is disposed at each of the air flow openings in order to impede or prevent the escape of air from the restraint volume compared to the inflow at the respective air flow opening. Such resistance elements may be formed by a second layer, displaced fabric threads, flexible fabric web sections and other elements such that a check valve function is provided.

Abstract: A method for operating a fuel cell system for the provision of electrical power is provided. The fuel cell system is disconnected when control electronics detect a fault. The fault that led to the disconnection is evaluated by the control electronics. An automatic restart of the fuel cell system through the control unit occurs if the evaluation of the fault permits this.
Abstract: A radiator grill arrangement for a motor vehicle front end of a motor vehicle with a number of air passage openings, which can be closed at least substantially by at least one flap element is provided. The at least one flap element is supported so as to be able to swivel about an associated flap axis. In driving states of the motor vehicle in which little cooling air is needed for the engine or engine compartment, the entire flap arrangement or a part of the flaps can thus be closed in order to improve the drag coefficient cw of the motor vehicle and to save fuel. Also in the parked state of the motor vehicle with the engine switched off, it is possible to close the flap arrangement in order to ensure a more aesthetically pleasing appearance of the motor vehicle.

Abstract: In a roof structure for the body of a motor vehicle with front roof pillars which are interconnected via a roof frame element, the roof frame element is arranged in a center section of the roof structure in relation to the connecting section thereof to the respective roof pillar so as to be set back in the longitudinal vehicle direction.
Abstract: A method for operating a fuel cell system for supplying at least one electrical consumer with electric energy is provided. The fuel cell system includes a fuel cell and an accessory for supplying the fuel cell. The efficiency of the fuel cell system is determined and the fuel cell is switched off temporarily when the efficiency of the fuel cell system falls below a switch-limit efficiency.
Abstract: A powertrain system includes an engine mechanically coupled to an electro-mechanical transmission selectively operative in one of a plurality of transmission operating range states and one of a plurality of engine states. A method for controlling the powertrain system includes determining a current transmission operating range state and engine state, determining at least one potential transmission operating range state and engine state, providing an operator torque request, determining preferability factors associated with the current transmission operating range state and engine state, and potential transmission operating range states and engine states, preferentially weighting the preferability factors for the current transmission operating range state and engine state, and selectively commanding changing the current transmission operating range state and engine state based upon the preferability factors and the operator torque request.

Abstract: A device for inflating an at least two-layered air bag folded to form an inflatable belt for a safety system of a motor vehicle equipped with a gas generator is provided. The gas stream generated by the gas generator is directed onto the air bag from the outside and the gas stream produces an opening in at least one of the layers of the air bag in a physical process.
Abstract: A door for a motor car includes a door support with at least one metal carrier element at least partially provided with plastic. The at least one metal carrier element is formed as an internal high pressure formed part. At least one metal reinforcement part and/or support part is/are attached to the metal carrier element.
Abstract: A pair of external vehicle mirrors with a driver-side external vehicle mirror and a passenger-side external vehicle mirror are provided. Each have a mirror foot and a mirror housing pivotably attached, in which an adjustable mirror glass is arranged. The mirror housings of the two external vehicle mirrors are constructed symmetrically, so that an identical oncoming wind flow situation is achieved, and that on a rear side of the two mirror housings there is arranged a mask encompassing the mirror glass, the mask of the driver-side external vehicle mirror being formed asymmetrically to the mask of the passenger-side external vehicle mirror.
