Real-Time Vehicle Models for Simulations of Ride Comfort

The functional development and test of complex automotive mechatronic devices require detailed and sophisticated vehicle models that have to fulfill real-time requirements if they are to be used in hardware-in-the-loop simulations. There is an increasing demand for more detailed plant models as a basis for the development and test of complex control algorithms in ride-comfort. This paper presents a method to integrate ride-comfort characteristics into well-established real-time vehicle models as regards engine-, drivetrain- and carbody vibrations. Thus it is possible to simulate characteristics that are essential for the development and test of comfort-related automotive mechatronic devices.
