METHOD, CONTROL DEVICE, AND COMPUTER PROGRAM PRODUCT FOR DIAGNOSING THE FUNCTION OF AN EXHAUST GAS AFTERTREATMENT DEVICE OF AN INTERNAL COMBUSTION ENGINE
The invention relates to a method, a control device (7), and a computer program product (11) for diagnosing the function of an exhaust gas aftertreatment device (2) of an internal combustion engine (1) that has two catalytic converters (3, 4) which are arranged one behind the other in the exhaust gas mass flow (10a) and which are capable of storing oxygen. The method is carried out by means of an electronic control device (7), wherein the internal combustion engine (1) is first operated in a conditioning mode (KBM) in order to pre-condition the two catalytic converters (3, 4), a first and second sensor signal (Sig1, Sig2) being received. The sensor signals (Sig1, Sig2) represent the oxygen content (O2_1, O2_1) in the exhaust gas mass flow (10a) directly after the first catalytic converter (3) and directly after the second catalytic converter (4). When the pre-conditioning process of the catalytic converters (3, 4) is completed, the internal combustion engine (1) is operated in a diagnostic mode (DBM), and an integration over the oxygen mass flow between the catalytic converters (3, 4) or after the second catalytic converter (4) is started in order to ascertain an oxygen mass flow integral (SMI_UFC). The integration over the oxygen mass flow and the diagnostic mode (DBM) are stopped on the basis of different thresholds, and the value of the oxygen mass flow integral (SMI_UFC) is ascertained, said value forming the basis for whether the second catalytic converter (4) is diagnosed as being "fully functional", "still fully functional but in an aged state," or "no longer functional". The aim of the invention is to advantageously allow a selective maintenance operation to be carried out in the event of a failure of the exhaust gas aftertreatment device.
The invention relates to an electrical connection device and to an electric drive machine comprising at least one electrical connection device. The electrical connection device (1) is used to electrically connect at least one winding of a phase of an electric drive machine and comprises at least one bus bar (21, 22, 23) and, connected to the bus bar (21, 22, 23), at least two line elements (31, 32) designed for electrical connection to a winding of a phase of an electric rotating machine, the line elements (31, 32) being fixed to one another by means of a clamping element (50). Using the electrical connection device proposed here and the electric drive machine equipped therewith, devices are provided which ensure, in a simple and economical way, a long service life despite oscillations that occur.

The invention relates to a vibration damper (16) with a fixing means (18) which fixes a damper mass (10) if a first limit frequency is reached or undershot and if a second limit frequency is reached or overshot. Here, the damper mass (10) is preferably fixed solely by the rotational-frequency-dependent centrifugal force which displaces, for example, one control mass (20) per damper mass (10) in the radial direction R counter to the force of a control spring (22). Resonances which lie outside the limit frequencies can be avoided by the vibration damper (16) being switched on and off. When used in the drive train of a motor vehicle, with the vibration damper (16) preferably being connected in the drive train here to a crankshaft of an internal combustion engine, the vibration behaviour of the crankshaft can be influenced in such a way that the amplitude of the vibrations of the crankshaft lies below a predefinable limit amplitude.

The output-side assembly is mounted in the first assembly by means of a rolling bearing, the rolling bearing being sealed towards both sides in each case by a seal that is effective between the first assembly and the output-side assembly, and one of these two seals delimiting, on its side facing away from the rolling bearing, a lubricant chamber which extends as far as the toothing of the flexible gearing element and of the output-side assembly.
The hydraulic system (1) presented here advantageously makes it possible for the sump to be designed merely in the form of a dry sump (5) which does not contain a separate pump module with a dedicated drive motor for delivering the hydraulic medium. Rather, hydraulic medium is delivered from the dry sump (5) via the dry sump pump flow (7) into a high sump (3), which is located above the dry sump (5). It is thus possible for the dry sump (5) to be made much smaller than a conventional gearbox sump or an oil pan. At the same time, it is possible to avoid the situation where the presence of a pump module in the gearbox sump means that, rather than the level of hydraulic medium being able to be kept beneath all the rotating components, components rotate in the hydraulic medium. In comparison with known systems, the design of the hydraulic system (1) proposed here therefore avoids churning losses. At the same time, having a common drive shaft (11) enables the drive of the pump flows (7, 9) to allow the corresponding pump module (6) to be easily controlled and to be of a simple construction.
