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.

Behavior model of an environment sensor

A hydrodynamic torque generator for test benches includes at least one inlet valve and at least one outlet valve, and a control device for valve positioning, the control device including an open-loop feed-forward controller and a closed-loop feedback controller.

Hydrodynamic torque generator for test benches and control method therefor

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.

Test rig for dynamic test assignments on internal combustion engines, and method for operating a test rig of this kind

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

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