Driving Simulators Symposium: The Idea Behind DSC 2015 Conference - Driving Simulators Symposium 16-18 SEPTEMBER 2015, TÜBINGEN (GERMANY) - 17 SEPTEMBER 2015 The development of simulators market and technology has produced a variety of solutions, ranging from highly customized and tuned machines to multi-purpose platforms. Yet, do we really know which solution is best for the intended simulator usage? [...] What are the trends in simulator use, design and architecture? [...]First of its kind, this symposium is the ideal settings for a fair comparison of the variety of solutions available today.

INTRO to Human in the Loop Simulation EXAMPLE 1: LIMITATIONS OF DESKTOP SIMULATORS FOR VEHICLE DYNAMICS In Desktop Simulators for Vehicle Dynamics, a Driver Model is employed for generation of realistic driver controls in relation to the task requested (i.e. maneuver) Motorsport Application: Perfect race car setup for desktop simulation!!! Too sharp and unstable for the real driver Poor modeling of the driver-race car combination mainly due to: 1. Poor modeling of driver interaction with the vehicle i.e. drive model 2. Poor modeling of tyre behavior in actual operating conditions i.e. tyre model DSC 2015 EUROPE Driving Simulation Conference & Exhibition Giuseppe Callea 6
INTRO to Human in the Loop Simulation EXAMPLE 2: LIMITATIONS OF TRADITIONAL DEVELOPMENT PATH FOR HUMAN-MACHINE INTERFACE (HMI) Due to the rising amount of information made available by the vehicle, the road and other infrastructures, a significant effort is made by car manufacturers in order to deliver to the driver the largest part of this information Perfect HMI Design!!! The system delivers constantly all available information to the driver When above HMI design is then tested with a real driver, the system is judged as annoying and disturbing the driver while executing his/her tasks DSC 2015 EUROPE Driving Simulation Conference & Exhibition Giuseppe Callea 7
Added Value of Human In The Loop Simulation ADDED VALUE OF HUMAN IN THE LOOP SIMULATION Added Value of HIL Simulation Possibility to verify how the system is perceived by the real driver Driver perception is only useful if the driver is immersed in a realistic simulation (i.e. enough realistic to deliver useful information with respect to the correspondent interaction experience in the real word) Problem of managing available visual/audio/motion resources in order to achieve realistic simulation for the desired interaction experience DSC 2015 EUROPE Driving Simulation Conference & Exhibition Giuseppe Callea 8

Simulator - Strenghts BHAITECH SIMULATOR - STRENGHTS Motion Control Flexibility In-house development of the entire control chain for simulator motion: vehicle model/cueing algorithm/low level hardware control possibility to use/bias non-uniformly simulator motion resources according to the job required Interfacing Capabilities Machine hardware/software architecture developed for easy and quick interface with any external vehicle component in the form of both software or hardware in the loop Projection System and Simulator Screen not installed on the Stewart Platform possibility to switch quickly from one vehicle cockpit to another DSC 2015 EUROPE Driving Simulation Conference & Exhibition Giuseppe Callea 12
Simulator Strenghts & Weaknesses BHAITECH SIMULATOR STRENGHTS Limited Machine Dimensions The simulator suits well investigations in the medium/high frequency range e.g. vehicle ride studies BHAITECH SIMULATOR - WEAKNESSES Limited motion amplitude due to limited travel of platform actuators careful use of machine motion resources in order to achieve a realistic interaction experience for the analysis under development DSC 2015 EUROPE Driving Simulation Conference & Exhibition Giuseppe Callea 13
Simulator - Challenges and Future Development BHAITECH SIMULATOR CHALLENGES AND FUTURE DEVELOPMENT Appropriate use of simulator motion resources to achieve a satisfactory trade-off between the primary and secondary interaction aspects still one of the main objects of research and development. partially achieved as a result of a significant development effort but still on-going. Not only a matter of motion control! simulator architecture inevitably suits better some applications/investigations and worse some other.
