Automotive: Driving Simulator

The research driving simulator of C.v.O. University of Oldenburg and OFFIS is a fixed-based simulator platform. The basic simulator software is SILAB which is used to create the road geometry, landscape and traffic scenario. It includes modules for the simulation of vehicle dynamics, sensor models, data recording and also most of the scripting for empirical studies is done within the software or its extensions. To investigate cooperative traffic scenarios, the software can be distributed across a network of computers which allows the integration of multiple simulators. For testing purposes, we have currently connected a second workstation equipped with a game controller input device. Theoretically up to 20 such additional workstations could be integrated for very complex platooning scenarios. It is work in progress to extend car2car and car2infrastructure modules.


In 2019, we upgraded the center console with two full HD touch screens that can be used for secondary tasks, as navigational displays or further HMI’s of future driving automation systems.



The main visualization uses a 3-beamer setup (since 2018: Sony VPL-VW260ES 4K Ultra-HD) and offers a maximum field of view of 160 degree (previously 150). Two displays with a resolution of 1024*768 are used for the simulation of left and right exterior mirror. The cockpit instrument uses a DVI display with a resolution of 1280*800. Within the driving simulator, software settings can be adjusted to simulate planar, convex and aspheric mirror types.

Audio Simulation

A Teufel 5.1 speaker system is integrated into the platform for audio feedback. The sound system uses 3D OpenAL sound simulation for the ego vehicle and surrounding traffic participants, but also allows to easily integrate experiment specific sound files.


Three Lexium Schneider CAN bus servo drives (LXM05A) apply force feedback and vibration signals with adjustable amplitude and frequency on the steering wheel as well as accelerator and brake pedal. To integrate additional hardware devices (e.g. indicator lever or switches) a WAGO CANopen fieldbus controller (750-337) is connected which can control up to 64 different D/A converter modules. Finally, an Ergoneers Dikablis Professional eye-tracker system (Full HD resolution, 60Hz tracking) is used to feed gaze data into the simulator in real-time.

Driver Assistance System Development

Within most of our projects advanced driver assistance systems (ADAS) are an integral part of our investigations. We already incorporated several systems from external partners in past projects, but in parallel also worked on developing our own systems using a fully model-based system design approach, based on Ansys SCADE Suite / Display and Matlab Simulink. The generated c-code (KCG / Targetlink) is embedded into a small wrapper code which is compiled as .dll for the SILAB driving simulator software. Currently available systems for “Autobahn” driving ( freeway / highway) are Adaptive Cruise Control (ACC), Lane Keeping Assistence System (LKAS), Lane Change Decision Aid Systems (LCDAS, e.g. blindspot warning, vehicle closing function) and finally a fully autonomous lane change assistant (LCA).

Since 2020, we are also able to drive first intersection scenarios (Y and X intersection layouts, T intersection not used yet) with new driving automation functions (turn right, turn left with traffic in one opposing lane).


Since its installation in 2009, the driving simulator has been used in a number of national projects (IMoST 1 and 2, CSE 1 and 2, PIRE 1, PIRE 2, AutoAkzept, SituWare) and EU research projects (e.g. HoliDes, Companion, AutoMate) and it is an important demonstrator platform which will be used in upcoming projects in the automotive domain.
