Implementation of active steering systems into a multibody vehicle model by co-simulation

摘要

Besides yaw rate control by braking intervention or torque vectoring, vehicle dynamics can also be stabilized by rear wheel steering. Alternatively the front wheel steering angle can be adjusted. This paper demonstrates the simulation process of combining a validated multibody vehicle model with a Matlab/Simulink® controller model by co-simulation. The adjustments of the multi-body model as well as the control algorithms of the active steering systems are described. Simulations of typical driving maneuvers show the improvements of vehicle handling by these systems.
