Abstract

An improved monitoring of a measurement chain with a sensor is achieved by using a broadband test signal. Thereby, the entire frequency range of a sensor can be covered with one test signal. There is no need to switch between different test signals and the available time for a diagnostic run can be used optimally. The broadband test signal allows better separation of the test signal and the useful signal. The integrity of an AC current measurement is increased by this approach. This can simplify the monitoring of a DC current sensor or even eliminate the need for an additional DC current sensor. In both cases, cost savings can be achieved.

Abstract

The operation of a mechatronic system with a power converter is advantageously and flexibly improved with regard to electromagnetic interference emission and acoustics. A regulation of the instantaneous switching frequency is proposed, with the natural variation of the switching frequency of the delta-sigma PWM in the cycle of the fundamental voltage being taken into account, which can achieve advantages in terms of EMC, acoustics and switching losses. The regulation of the instantaneous switching frequency in particular creates a possibility of generating a specific, calibratable noise with the underlying drive. It can be used to generate a brand-specific, recognizable noise of a vehicle and also to meet normative requirements for the acoustic perceptibility of purely electric vehicles (BEV).

Abstract

The problem addressed by the present invention is that of providing an electrical conductor in which, with the smallest and most flexible cross-sectional area/shape possible, so that, for example, when using an AC machine, a high filling degree of the slots can be achieved, there is neither an increase in the resistance caused by the flow displacement effect, nor an increase in the resistance caused by the proximity effect. In addition, it is possible to connect this electrical conductor to at least one further electrical conductor easily and economically. This problem is solved in accordance with the invention in that an electrical conductor is formed, which comprises a plurality of individual electrical conductors made of a first metallic material, the individual conductors running along the longitudinal axis of the electrical conductor and being distributed over the cross-section of the electrical conductor such that the individual conductors are distanced from one another, with gaps being formed between the individual conductors and the individual conductors being surrounded by a second metallic material which fills the gaps between the individual conductors, the electrical conductivity of the first metallic material being greater than the electrical conductivity of the second metallic material so that, when an electrical current flows in the electrical conductor, the electrical current flows predominantly into the individual conductors made of the first metallic material and, by contrast, only a smaller part flows through the second metallic material.

Abstract

The invention relates to a computer-implemented method for the probabilistic prediction of sensor data. Starting from existing time curves of a target variable and optionally from further auxiliary variables, an RCGAN according to the invention is able to calculate the probability distribution of future values of the target variable and to predict the future values of the target variable therefrom. The predicted future values of the target variable can be fed back to the technical system in which the method according to the invention is used so that the latter can adjust parameters on the basis of the obtained findings. The prediction of the filling amount of cylinders of an internal combustion engine is used here as a specific technical application.

Abstract

A method for cooling an engine includes increasing the pressure of a liquid coolant from a first pressure to a second pressure. Thereafter, components of the engine to be cooled are contacted with the liquid coolant so that the liquid coolant at least partially evaporates and forms a vapor with a particular state. Thereafter, the vapor is fed to a throttle to reduce the pressure of the liquid coolant to a third pressure. The particular state of the vapor is determined based on the temperature and the third pressure of the liquid coolant downstream of the throttle, and based on the second pressure of the liquid coolant under an assumption that the throttle is an adiabatic throttle such that enthalpy of the liquid coolant remains constant as the liquid coolant passes the throttle. A desired vapor state adjustment is made based on the determined particular state of the vapor.

Abstract

A method for testing software of an electronic control unit of a vehicle includes, in a first step, executing a driving cycle, whereby input quantities and output quantities of the electronic control unit are recorded. In an additional step, the driving cycle in accordance with the first step is repeated without once again executing the driving cycle with the vehicle on the testing device so that additional output quantities are made available. It is ascertained that the software comprises a function that recognizes whether a driving cycle is being executed with the vehicle, based on there being a deviation between at least one output quantity that had been recorded in the first step and the corresponding output quantity provided in accordance with the additional step. Based thereon, a function of the electronic control unit is excluded from being further developed or processed during a subsequent development step.

Abstract

It is an object of the present invention for a determination of the pressure in the exhaust system of an internal combustion engine to be realized with the least possible complexity. Said object is achieved according to the invention in that the pressure in the exhaust system of an internal combustion engine is determined in a manner dependent on the signal of a first lambda probe (3) and the signal of a second lambda probe (4). Here, in particular, a signal value of the first lambda probe and a signal value of the second lambda probe are assigned a value which represents the pressure in the exhaust system of an internal combustion engine. That is to say, the present invention is based on the realization that there is a relationship or a correlation between the signal values of the first lambda probe and the signal values of the second lambda probe and the pressure in the exhaust system. The pressure in the exhaust system is thus a function of the signal of a first lambda probe and the signal of a second lambda probe. According to the invention, use is advantageously made only of existing probes, and an intervention into the control/regulation of the probes is not necessary. Here, the first lambda probe (3) is a broad-band lambda probe, and the second lambda probe (4) is a voltage transient lambda probe.

Abstract

The invention relates to a method and a corresponding device for adapting a knock control for an externally-ignited internal combustion engine for determining a knock level reference value for controlling knock, which value is individual to an internal combustion engine and operating point. When operating the internal combustion engine, an ignition angle is varied for at least one cylinder of the internal combustion engine, in order to determine a position of a knock limit depending on a knock level. Structure-borne sound waves of the internal combustion engine are detected by at least one knock sensor and emitted as the knock level. The measurement values for knock levels depending on the ignition angle, ascertained when varying the ignition angle, are used to determine the knock level gradients depending on the ignition angle. A knock level reference value individual to an internal combustion engine is equated to the knock level of a specific ignition angle, at which the knock level gradient corresponds to a limit knock level gradient.

Abstract

The invention relates to a method which allows a reliable detection of the operating state independent of the state and position of the compressor blades and thus an optimal compressor operation. In an advantageous manner according to the invention, the deviations from the ideal state of each individual compressor blade are ascertained when starting up the compressor after reaching the minimum rotational speed in order to align the compressor blades. The passing times of each compressor blade, said passing times being measured during operation, can be corrected on the basis of the deviation determined for the individual compressor blades. Said correction allows a precise determination of the operating state and an efficiency-optimal operation of the compressor below the pump threshold. During each start of the compressor, the deviations of the compressor blades are re-ascertained with respect to the ideal state, adapted, and incorporated into the analysis. The thus corrected measured passing times are used to ascertain the deflection due to the sag of the compressor blade, wherein only the sag due to the flow mechanics is ascertained advantageously according to the invention. An ascertainment of the operating point is achieved independent of the state and the position of the compressor blades.

Abstract

For complex systems for exhaust gas recirculation, it is difficult to set a certain exhaust gas recirculation rate accurately and quickly. According to the invention, a cascade controller having an inner and an outer control loop is proposed, wherein the outer loop controls the oxygen concentration in the intake system and the inner loop controls the exhaust gas recirculation rate. According to the invention, the exhaust gas recirculation rate, which can be set relatively quickly, is advantageously used as an auxiliary control variable, which is a measure of the oxygen concentration in the intake system, wherein the oxygen concentration in the intake system reaches a new specified value only with a relatively large time delay.

Abstract

The invention relates to a dual-clutch gearbox for motor vehicles. The problem addressed by the invention consists in providing a sequentially power-shiftable dual-clutch gearbox that comprises at least nine forward gears for motor vehicles with a transversely installed engine. Said gearbox has a compact construction, both axially and radially, and allows a harmonic ratio series to be implemented for the highest possible degree of comfort and traction. This problem is solved by means of a special gearbox structure which uses just four gear-wheel planes (ZRE1, ZRE2, ZRE3, ZRE4) for the forward gears, as well as four shifting element units (B, C, D, E, F, G, H, I) which act on both sides, and one single shifting element. In addition, the diameters of the eight gear-wheels (8, 9, 10, 11, 12, 13, 14, 15) of the four gear-wheel planes are very small due to multiple tooth engagements in gears one and two, and, in proportion to the number of forward gears, the number of components is kept low by virtue of multiple usage for the implementation of the forward gears. Furthermore, a comfortable gear ratio progression can be achieved in the gearbox for the nine power-shiftable forward gears by using the combination of the gear ratios.

Abstract

The invention relates to a method of controlling a power-splitting transmission having an internal combustion engine and at least two mechanically coupled electrical machines (El, E2). The transmission ratio of the transmission is determined by the torque and/or the rotational speed of the electrical machines (El, E2 ). The control of the torque and/or rotational speed of the electrical machines (El, E2 ) is based on the definition of a leading electrical machine. An optimum rotational speed of the internal combustion engine (Dz_Vm_opt) is formed using consumption and/or power criteria. A torque (Dm_El/2_set) and/or a setpoint rotational speed value for the leading electrical machine are/is formed from the driver's request and the rotational speed of the internal combustion engine (Dz_Vm_act). The setpoint value for the following electrical machine is then ascertained by means of a power analysis.

Abstract

The invention relates to a method and an associated device for simulating the driving characteristics of a drive concept to be developed for a motor vehicle. The aim of the invention is to provide a method and an associated device for simulating the driving characteristics of a drive concept to be developed for a motor vehicle, using which the longitudinal dynamics and the energy requirements of designed concepts are simulated, compared with one another and validated during an actual driving operation. According to the invention, in order to simulate the driving characteristics of a drive concept to be developed for a motor vehicle during an actual driving operation for a production vehicle, the engine and transmission control are influenced by means of an additional control unit in such a way that the longitudinal dynamics of the production vehicle correspond to that of a designed hybrid drive. To achieve this, the additional control unit for influencing the longitudinal dynamics of the conventional carrier vehicle intervenes in the signal path of the accelerator pedal in the carrier vehicle and can determine the position of said pedal, simulating the position of a 'virtual accelerator pedal' by means of a signal generator, thus regulating the acceleration of the vehicle. The control unit accesses the CAN data bus of the drive train of the carrier vehicle to deliver the current speed, the current gear selected and the position of the brake pedal, which represent important input variables for the simulation.

opt) that can be predetermined. Based on this, a throttle valve position is set. Parallel to this, a desired torque is calculated for the fuel path with a reference lambda value, and an actual charge is calculated to yield a fuel amount to be injected. The reference lambda value results from an optimal lambda value for the mode of operation of homogeneous compression ignition, as long as the lambda value is within the rich and lean limits, respectively, of the combustion method of homogeneous compression ignition. The fuel mass is varied within the rich and lean limits to compensate dynamic processes.

• F02D 41/14 - Introducing closed-loop corrections

Abstract

The invention relates to a valve drive for internal combustion engines, comprising at least one cam assembly which can be axially displaced on a camshaft. Said assembly consists of at least two cams (2, 3) having different profiles and actuating optionally at least one gas exchange valve for adjusting different valve lifts and/or valve timings. For this purpose, one cam is connected to the camshaft so as to rotate with the camshaft and the other cam is mounted so as to be rotated on the camshaft. The cam that is rotationally mounted on the camshaft can be positively connected to and released from the cam that is connected so as to rotate with the camshaft via a controlled pilot and main locking plunger (6). The rotationally fixed cam has a larger profile height than the rotationally mounted cam. The larger profile height is designed for a relatively large lift of the gas exchange valve, while the lower cam profile height is designed for smaller lift heights. By displacing the cam assembly when the cams are coupled, the cam with the larger or the smaller profile height can be engaged with the gas exchange valve. A zero lift of the gas exchange valve can be adjusted, when the cam with the smaller profile height engages, by decoupling the rotational cam from the cam that is arranged on the camshaft so as to rotate therewith.
