Abstract: Various embodiments of the present disclosure are directed to a method for carrying out a test run on a test stand. The method in some embodiments reduces a deviation between a comparison simulation value and a comparison reference value when carrying out a test run on a test stand with a test object by simulating via a simulation unit a number of simulation values using a number of specified reference values starting from a selected reference value, determining a corrected reference value which is specified to the simulation unit for simulating a corrected simulation value and determining at least one setpoint variable using the corrected simulation value.

Abstract: Various embodiments of the present disclosure are directed to test stands for generating test runs on the basis of a test drive using a vehicle along a driving route. In some embodiments, a test stand determines at least one idle operating time of an internal combustion engine and/or at least one overrun operating time of the internal combustion engine from a time curve of a vehicle speed and a time curve of a gas pedal position. The test stand may further set a specified idle control mode instead of the operating control mode during an idle operating time and/or a specified overrun control mode is set instead of the operating control mode during an overrun operating time in the test stand automation unit in order to carry out the test run.

Abstract: Aspects of the present disclosure are directed to estimating a gearbox gear for a test run from available measured values of a test drive. In some embodiments, a chronological sequence of a vehicle speed and an engine speed may be used as measured values, a number of areas with a linear relationship between the vehicle speed and the engine speed being identified by means of a clustering algorithm from data points from related vehicle speeds and engine speeds. The clustering algorithm, in accordance with some specific embodiments, assigns the data points to the number of areas and calculates a cluster center for each area, which is interpreted as a gear. The gear linked to the cluster center of the area is assigned to the data points of an area in order to obtain a chronological sequence of gears, and used as a target value of the test run.

Abstract: The invention relates to a method the assessing the controllability of a vehicle by a driver in a risky or problematic situation. In order to carry out assessment of the controllability of a vehicle early, the following steps are provided: a. modelling the drive train and the movement dynamics of the vehicle, b. modelling situation conditions and environmental conditions, c. selecting a risky or problematic situation, d. selecting a driver capability type, e. modelling the driver's reaction as a function of the selected driver capability type. f. simulating the dynamic vehicle behaviour in the longitudinal and transverse directions of a planned trajectory on the basis of the drive train model and movement dynamics model for the predefined situation and environmental conditions when the selected risky or problematic situation occurs, g.
