MBS-integrated control of longitudinal and lateral dynamics for riding comfort simulation

Abstract

In modern vehicle development processes simulations of virtual roads are an essential part for the analysis of riding comfort. Especially the combination of multi-body simulations (MBS) and 3D-simulators for the true experience of vibrations creates a big opportunity of improving design results and reducing costs at the same time in an early development stage. However, the requirements and restrictions of MBS and the input of its results into 3D-simulators strongly complicate the development of a virtual, MBS-integrated driving dynamics controller. Since standard approaches can’t be used here, a new control solution including a parameterized anti-windup law for the longitudinal dynamics as well as a special gain-scheduled law for the lateral dynamics is presented. At the end, the control algorithms are applied to realistic car models and different simulation load cases like driving on virtual bumpy roads or braking maneuvers – always with the main goals of good vibrational comfort and a true experience in the 3D-simulator in mind.
