Abstract: In a method and apparatus for measuring and displaying the engine oil filling level in a vehicle having a filling level switch or sensor, measured values of the switch or sensor, in the form of determined time components, are summed to determine a state duration of a particular state of the engine oil filling level. The state duration is compared with predefined time limiting values of the respective state of the engine oil filling level. According to the invention, the length of the individual time components is determined as a function of driving-state-dependent parameters.

Abstract: A crankcase of an internal combustion engine with at least one main lubricant channel for supplying the internal combustion engine with lubricant and with at least one oil return flow channel (10) for return guidance of the excess lubricant into a reservoir container (11), wherein the oil return flow channel (10) exhibits a peg-shaped widening (12), which is formed by the attachment a bearing support of an oil channel core (18). The invention further concerns an oil channel core.

Abstract: A refrigerant compressor has a control valve for controlling the degree of conveyance of the refrigerant compressor by setting a drive housing pressure pC of the refrigerant compressor. A control body controls a conveying-side control line between a discharge chamber, acted upon by high pressure of the compressor, and the drive housing of the compressor, and also controls a suction-side control line between the drive housing and a suction chamber, acted upon by suction pressure of the compressor variably in a throttling and/or shutting-off manner. The control body is driven electromagnetically. To improve the refrigerating capacity and the control behavior of the refrigerating system, the control body, which can shut off both the conveying-side and the suction-side control line, is also driven by means of a pressure cell.

Abstract: A method and an apparatus for automated application of paint film to bodywork parts (1) and to a paint film composite (5) which is suitable for automation. A paint film composite (5) which is suitable for automation is created and adhesively bonded onto the bodywork part (1) in an accurate position and without any bubbles or creases by means of a robot-controlled application tool that is appropriate for this purpose. To securely hold the film composite (5), which has been picked up from a substrate, the suction grippers (30, 31) which grip the ends are angled in mirror-image form, in order in this way to prevent the ends from becoming detached from the suction grippers. The lower protective strip (9) is then at least partially pulled off, thus exposing the adhesive face of the useful part (6) of the paint film. The film composite (5) is aligned in the correct orientation at a short distance from the bodywork part (1) and the useful part (6) of the paint film is wiped onto the bodywork surface (1).

Abstract: A receiving unit for a controller for reception of input data is disclosed. The input data is transmitted as optical signals in an optical bus system in a vehicle. The receiving unit is coupled to an optical bus system and has a means for conversion of optical signals to electrical signals. A measurement arrangement is provided which measures a characteristic variable for the optical received power. The receiving unit optimizes the dynamic control of the optical level. The measurement arrangement is in the form of a digital circuit. Furthermore, an output port is provided for passing on the digitized measurement data.

Abstract: A passenger vehicle restraint system that is capable of being placed in different positions, consisting of an interior defined by a housing and at least one airbag, at least one gas generator for delivering gas to the interior in order to inflate the airbag, at least one controllable outlet provided on the housing which may be closed by a closing element, such that an internal pressure in the interior may be adjusted according to parameters relevant to passenger load during an accident. A restraint system, which is easy to construct and can be manufactured cost-effectively, is provided by an adjustable stop element limiting the opening movement of the closing element, which is coupled to the vehicle seat such that the stop element is displaced according to parameters relevant to passenger load, in order to adjust the outlet cross section defined by the closing element located in its closed position.

Abstract: The invention relates to a cooling system in which the fan output is determined by an output control from the characteristic curves of the fan motor, the operating parameters of the cooling system and the reference input variables predetermined in the form of temperature levels. Different characteristic curves for the activation of the fan motor are here assigned to the different set temperature levels. If the reference input variable for the control changes, this also results in a change of the characteristic curves for activation of the fan motor. In order to prevent the fan motor starting to howl, in the event of a change in the reference input variable for the fan control the operation of the fan motor is kept constant for an adjustable minimum waiting time.

Abstract: An apparatus for humidifying a gas stream includes a humidifier device having at least one membrane permeable to water vapor. The gas stream and a humid gas stream flow through a humidifier device, being separated from one another by the at least one membrane. The apparatus includes at least one bypass line configured to route at least part of one of the gas stream and the humid gas stream so that it does not come into contact with the membrane. In addition a method for humidifying a gas stream, includes flowing the gas stream through a humidifier having a membrane permeable to water vapor, flowing a humid gas stream through the humidifier separated by the membrane, and routing at least a portion of one of the gas stream and the humid gas stream using a bypass line so that it does not come into contact with the membrane, and varying a quantity of the portion so as to set a predetermined dew point in the gas stream.

Abstract: A front frame structure of a truck with upper longitudinal members and with lower longitudinal member elements which are connected to one another via vertical frame struts is provided. The lower longitudinal member elements are designed at least in some regions as collision-force-absorbing deformation bodies and are completely integrated into the frame structure.

Abstract: The present invention relates to a device for determining the roll angle and a system and a method for roll stabilization of a motor vehicle with a yaw rate sensor arrangement (1) of an existing driving dynamics control system which, for detecting a combined signal consisting of yaw rate and roll rate, is with its measuring axis inclined at a predetermined inclination angle (?) in relation to the vertical axis in the plane passing through the longitudinal axis and the vertical axis of the motor vehicle; and with at least one observer (3), preferably designed as a Kalman filter, which, for determining the roll angle (?), splits the combined signal detected by the yaw rate sensor arrangement (1) into the two signal components yaw rate and roll rate.

Abstract: In a camshaft adjusting device for adjusting a phase position of a camshaft relative to a crankshaft of an internal combustion engine with a gear mechanism including at least three drive connections, a locking element is provided, with which at least two of the at least three drive connections, can be locked to one another in a rotationally fixed manner depending on operating conditions for retaining a particular phase position of the camshaft relative to the crankshaft of the internal combustion engine.

Abstract: A drive system for an electrical machine is provided. The system includes a control unit and a monitoring unit, which is independent of the control unit. The control unit includes a device that converts one or more incoming operating parameters of the electrical machine to an output value. The monitoring unit includes a device that converts the operating parameters to a comparison value, with the conversion being carried out more quickly in the control unit than in the monitoring unit. A comparator compares the output value or an intermediate value of the output value with the comparison value of the output value or of the intermediate value.
