Abstract: Detecting manipulation of an SCR catalytic converter system of a motor vehicle. A control command (61) for the SCR catalytic converter system, transmitted from a control unit outside the motor vehicle, is received by the motor vehicle. Manipulation is detected (57) if a response (55) of the SCR catalytic converter system to the execution (54) of the control command (61) does not correspond to expectation. Embodiments also relate to monitoring manipulation of the SCR catalytic converter system. Here, a control command (61) for the SCR catalytic converter system is transmitted (41) to the motor vehicle (10) from a control unit (20) outside the motor vehicle.

Abstract: The invention concerns a method (200) of detecting an emulator for an SCR catalytic converter system (10) with the following steps: operating the SCR catalytic converter system (10) in a test state; and measuring a test variable of the SCR catalytic converter system (10); and deciding whether the test variable is behaving as for an SCR catalytic converter system (10) with or without an emulator.

Abstract: A method for supporting a driver of a motor vehicle during a driving maneuver, including the following: (a) determining a driving path in which the motor vehicle moves when the driving maneuver is carried out and automatically or semi-automatically carrying out the driving maneuver; (b) detecting the surroundings of the motor vehicle during the driving maneuver; (c) stopping the motor vehicle if an object is detected in the driving path and resuming the driving maneuver as soon as the object has left the driving path and/or decelerating the motor vehicle and slowly resuming the driving maneuver if an object is detected outside the driving path. Also described is a device for carrying out the method.

Abstract: Procedures for diagnosing an exhaust gas treatment device, which is dosing a reagent into the exhaust gas area of a combustion process, whereby the reagent is brought up to a dosing pressure and subsequently dosed, at which the diagnosis is undertaken with the aid of an evaluation of a pressure drop of the reagent, and a device for implementing the procedure are suggested. After turning off the pump a pressure drop that occurs afterwards is evaluated. The evaluation of the pressure drop considers a leakage loss of the pump.

Abstract: Suggested are a procedure for diagnosing a metering valve (14) of an exhaust gas treatment device (22), which doses a reagent (16) into the exhaust gas area (11) of a combustion process, whereby the reagent (16) is brought to a metering pressure (p_Ds) by a pump (17) and which is dosed by the metering valve (14), at which the diagnosis is undertaken by evaluating a pressure drop (50, 51, 60, 61) of the reagent (16), and a device for implementing the procedure. At first the pump (17) is switched off. Subsequently the metering is continued during a diagnosis metering operation. The reagent quantity (m) that has been dosed is determined during the diagnosis metering operation. Not until reaching a dosing quantity threshold (m_Lim) the evaluation of the pressure drop (50, 51, 60, 61) is terminated.

Abstract: A personal care article (20) has a longitudinal-direction (22); a relatively shorter, lateral cross-direction (24); a first end-edge (74); a longitudinally-opposed second end-edge (78); a first side-edge (62); and a laterally-opposed second side-edge (64). The article includes a liquid-permeable topsheet layer (26), and a backsheet layer (28) operatively connected in facing relation with the topsheet layer. A first end-notch (80) is formed to extend inward from the first end-edge (74), and a second end-notch (82) is formed to extend inward from the second end-edge (78). In a particular aspect, at least a first, end-line of bending weakness (88) extends from an inboard, apex end region of the first end-notch (80). In other aspects, a first side-notch (66) can be formed to extend inward from the first side-edge (62), and a second side-notch (70) can be formed to extend inward from the second side-edge (64).

Abstract: The present invention relates to a method and an apparatus for producing a reinforced socket on an extruded plastic tube made of thermoplastic material, preferably a corrugated tube, in which the tube is provided with end sockets at predetermined segment lengths. One end of the plastic tube or of a segment thereof is placed on a support mandrel and together with this support mandrel is rotated about its longitudinal axis. During the rotation, a layer of plastic is extruded onto a pre-formed socket region of the tube and/or onto the support mandrel, forming a reinforced socket formed on the tube.

Abstract: A magnet valve with low noise upon shutoff from the pressure limiting function. The magnet valve has a two-part valve tappet, whose inner valve tappet part has the closing member of a seat valve. The closing member is circumferentially engaged in spaced-apart fashion, forming a gap space, by a tubular portion of the outer valve tappet part. From the gap space, a pressure fluid conduit leads to a control chamber, which is located between the face end, remote from the seat valve, of a magnet armature that cooperates with the valve tappet, and a valve dome. Upon shutoff of the magnet valve, the seat valve changes from its closing position to a partly open position, in which dynamic pressure in the gap space becomes operative and is transmitted through the pressure fluid conduit into the control chamber. The hydraulic force that is operative there on the magnet armature acts counter to the opening forces of the magnet valve and slows down its opening motion.

Abstract: An electromagnetically operated valve which attains an automatic establishment of a reduced flow cross section that is effective after a closing position of the valve. The valve has a magnet armature, longitudinally movable in a valve dome, with a valve tappet for actuation of a seat valve. The seat valve is located in a valve chamber from which pressure fluid conduits, leads to upper and lower face ends of the circumferentially sealed off magnet armature. When the valve is opening from the closing position, an additional force acting in the closing direction upon the magnet armature is generated because of the shaping of the seat valve, and as a result of this additional force the seat valve assumes a partly closed position that is different from its position of repose. The valve is applicable particularly to traction-controlled hydraulic brake systems of motor vehicles.
