Dynamic driving simulator

Platform for the investigation of user acceptance of different assistance systems and human-technology interaction (MTI or HMI)

-Realization of vehicle dynamics with arbitrary software tools (IPG CarMaker / PreScan)
-CAN communication enables the influence of steering wheel characteristics in the form of stiffness, damping and friction
-Coupling with communication hardware (dSpace / National Instruments): real-time transmission of moments and angles to the simulation environment / vice versa active adjustment of the steering wheel

Extension of the platform:

-Extension by a hexapod to a dynamic driving simulator
-Opening of new investigation areas: Higher speeds, sideslip angles and a better haptic feeling for the dynamic processes in the virtual vehicle

Dynamischer Fahrsimulator TU Ilmenau

Hardware-in-the-Loop test complex

The test bench is intended for testing in algorithms of antilock braking systems (ABS), electronic stability programmes (ESP) and other driving safety systems.

The hardware includes a master brake cylinder, four wheel brakes and hydraulic control. A hydraulic control unit (HCU) can follow the control strategies implemented in MATLAB / Simulink using the dSpace interface.
