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.
