Abstract: A computer-aided method for training an artificial neuronal network for the simulation of an environment sensor of a driver assistance system includes the following work steps: reading in traffic scenarios of a test journey; deriving test journey data and the sensor data to be output by the environment sensor from the traffic scenarios; generating a data stream which depicts the traffic scenarios from the perspective of the environment sensor; outputting the data stream such that the environment sensor can generate sensor data on the basis of the data stream and can provide same to a data interface at which the test journey data and the sensor data to be output are also provided; and reading the provided data into the artificial neuronal network.

Abstract: Systems and methods for recording an inventory of monitoring objects (1) of a plant (4) having a multiplicity of fixed or non-fixed areas (5) where monitoring objects (1) can be located. The plant (4) is suitable for carrying out sequences of operations using the monitoring objects (1) and has a multiplicity of detection devices (6) which are each assigned to an area (5) of the plant (4). The monitoring objects (1) are in each case provided with preferably contactlessly readable identification elements (3), which have a unique identifier. The detection devices (6) have a data connection to an arithmetic unit (7), which manages an inventory database (8).

Abstract: So as to make the co-simulation of subsystems of an overall system (1), which are reciprocally coupled by way of coupling variables (y1, y2), real-time capable, a mathematical model (M) of the subsystems (TS1, TS2) which is valid at the current operating point of the overall system (1) is ascertained from input variables (x1, x2) and/or measured variables (w1, w2) of the subsystems (TS1, TS2) based on a method of data-based model identification and, from this model (M), the coupling variables (y1, y2) are extrapolated for a subsequent coupling time step and made available to the subsystems (TS1, TS2).

By implementing a control system, which consists of an open-loop feed-forward controller and a closed-loop feedback controller, in the control device, a machine of this kind can also be used in dynamic test benches.

Abstract: Sensors in a test bench environment have to be parameterized in advance. This is a complex task that up to now has been performed mostly manually by a test bench engineer. In order to make the parameterization of a sensor (54) easier, it is proposed that the position of the sensor on the object under test (1) be ascertained through suitable localization methods and the ascertained position be compared with geometric data of the object under test (1), from which the position of the sensor (54) on the object under test (1) can be derived, and from this position on the object under test (1), the variable physically measured by the sensor (54) can be assigned to the sensor (54).

Abstract: A test rig for dynamic test assignments on internal combustion engines is equipped with a preferably electrical drive and/or loading device which is coupled to a control device for adapting and controlling setpoint values for a speed and a torque characteristic. For a test rig of this kind, in order to enable the setpoint values determined by a speed and a torque characteristic to be optimally adapted and controlled for the respective test assignment and so that they can be reproduced on the test rig in the best possible manner, the control device can be adapted in terms of adjusting the weighting of speed control to torque control.

Abstract: The course of torque transmitted though a driving shaft (3) between torque generating device (1) to be tested and a driving or loading mechanism (2) is determined during an identification phase in the completely constructed test bench with the use of a rotating driving or loading mechanism (2) at pseudo-stochastic rotational speeds. Determined are thereby parameters describing in a real and current manner the dynamic behavior of the driving shaft (3) whereby the parameters are used as an influence in further testing.

Abstract: In order to make it possible to also mount an original exhaust system (10) substantially leading away from the internal combustion engine (2) below the output axle (7) parallel to the extension thereof in a test rig for internal combustion engines (2), the driving engine or load generator (4) is mounted in a suspended manner at a certain vertical distance from the pedestal (1) on a support arrangement (6) mounted thereon, with the input axle (8) being substantially aligned with the output axle (7) of the internal combustion engine (2) that is to be tested, whereby the space from below the interference contour (9) of the driving engine or load generator (4) to the pedestal remains free for the passage of the exhaust system (10).
