Test bench for testing a drive component with a shaft using a model to calculate a future value of a state variable of the shaft

摘要

The invention relates to a test bench (1) for testing a drive component (2) for a vehicle (3), the test bench (1) has a shaft (4), an electric motor (5) which is connected to the drive component (2) via the shaft (4) can be coupled mechanically, and a control device (6) with a kinematic model (7) for modeling a kinematic system (8) which has at least the drive component (2), the electric motor (5) and the shaft (4), The control device (6) is set up and designed to use the kinematic model (7) to calculate at least one future value of a state variable of the shaft (4) for a future period of time and, depending on the future value of the state variable of the shaft (4), the state variable to regulate the shaft (4).
