Abstract

In order to be able to test the vehicle component assembly with better dynamics on the test stand, it is provided that in the simulation unit (20) by means of a simulation model (21) for at least one component of the assembly The drive train torque (T P ) and the braking effect (B) of the braking system (11) to calculate the instantaneous drive train speed of the component (n P ) and is used by the vehicle controller (14) using the calculated driveline speed (n P ) to control the at least one component, and the calculated drive train speed (n P ) to control the loader (8).

Description

technical field

[0001] The invention relates to a method and a test stand for testing an assembly of components of a vehicle, the assembly comprising a drive train, at least one vehicle controller handling the rotational speed of the drive train and a brake acting on the drive train on the test stand A system wherein the driveline of the vehicle is driven by a drive unit and a load torque is applied to the driveline by means of a loader coupled to the driveline, and at least one component of the combination is controlled by a vehicle controller based on the speed of the driveline. Background technique

[0002] There are many vehicle controllers in a vehicle, such as hybrid controller, engine controller, transmission controller, driving dynamics control system, etc., to name a few, which may be interconnected with each other via one or more vehicle buses. Many such vehicle controllers process speed either at the wheels such as via ABS speed sensors, or at drivetrain component...
