Frankfurt am Main / Offenbach – Honda wird als erster Automobilhersteller weltweit eine hochmoderne Fahrsimulator-Technologie – basierend auf einer revolutionären Architektur namens „DiM250“ (Driver-in-Motion) – einsetzen.
Die meisten Fahrsimulatoren greifen auf von Flugsimulatoren abgeleitete Bewegungstechnologie zurück und verwenden üblicherweise sechs Aktoren, damit sechs „Freiheitsgrade“ bereitgestellt werden können. Um Fahrgefühl, Handling sowie Beschleunigung innerhalb eines einzelnen Simulators bestmöglich abbilden zu können, greift das „DiM250“-System jedoch auf neun Aktoren zurück, wodurch zusätzliche Bewegungsbereiche erzeugt werden. Das ist einzigartig in der Branche.
„Wir gehen davon aus, dass wir ‚DiM250‘ hauptsächlich in Bereichen der Fahrzeugdynamik und Fahranwendungen einsetzen werden und dass das System zudem als zentrales Entwicklungs- und Testtool für unsere ADAS-, HMI- und Antriebstechnologien sowie für unsere autonomen Fahrtechnologien in frühen Entwicklungsphasen Anwendung finden wird“, erklärt Yasunori Oku, Executive Vice President, Honda R&D Europe (Deutschland). „Die ‚DiM250‘-Technologie wird uns als einheitliche Entwicklungsplattform für unsere Forschungs- und Entwicklungsaktivitäten dienen, mit deren Hilfe alle beteiligten Teams gemeinsam in einer kollaborativen Umgebung zusammenarbeiten können. “
Konstruiert wurde das „DiM250“-System vom Simulationssoftware-Entwickler „VI-grade“. Für Umsetzung und Fertigung war „Saginomya“, Spezialist für automatische Steuerungssysteme, verantwortlich. Die elektrisch betriebene Neun-Aktor-Plattform des Unternehmens ist ausgereifter als herkömmliche „Hexapod“-Entwürfe und das gesamte System bewegt sich mittels Gleiten auf Luftpolstern, anstatt auf zusätzliche mechanische Schienen zurückzugreifen. Die Luftpolster fungieren als Ausgleich zwischen den hohen Traglasten und den schwingenden Lasten und machen den Simulator extrem steif, geräuscharm sowie zuverlässig.
Die Integration von „Software-in-loop“ (SIL)- sowie „Hardware-in-loop“ (HIL)-Anwendungen innerhalb des Simulators ermöglicht Entwicklern und Ingenieuren die Bewertung von Verbesserungen innerhalb des Fahrzeugentwicklungszyklus noch vor der Entwicklung des eigentlichen Prototypen. Darüber hinaus kann der Simulator Problemszenarien genau nachbilden, um Sicherheits- sowie Steuerungssysteme zu testen.
„Wir blicken der fortlaufenden und erfolgreichen Nutzung unserer Technologie bei Honda R&D mit Freude entgegen, die dabei unterstützt, noch ausgereiftere Fahrzeuge in kürzerer Zeit zu entwickeln, während das Feedback eine kontinuierliche Verbesserung unserer Fahrsimulatoren-Lösungen sicherstellt“, so Jürgen Fett, Managing Director, VI-grade.
Der neue Simulator wird am Standort des Technikzentrums von Honda R&D Europe in Offenbach, Deutschland ab dem zweiten Halbjahr 2018 zum Einsatz kommen.

Marburg, Apr 13th, 2017 – VI-grade today announced that Volvo Car Corporation upgraded the revolutionary motion platform named DiM® (Driver in Motion), already in use at their premises in Torslanda, Sweden, with the newly developed active seat and belts from VI-grade.
“Since its installation back in 2015, we have been using DiM extensively to complement our tool chain, allowing us to physically experience our simulation models using human test drivers” says Carl Sandberg, Vehicle Dynamics Concept Engineer at Volvo Car Corporation. “Through the adoption of the brand new active seats and belts from VI-grade, we expect to further enhance the overall driving experience on our simulator, allowing driving dynamics and active safety systems to be experienced in an even more realistic environment right from the start of the development process.”
“Our active seats are based on cushions inflated by compressed air that apply different levels of pressure on different portions of the body; the effect of the active seat is combined with a proper tensioning of the active belts during braking and helps to better feel steady-state accelerations, which are always limited on driving simulators” said Diego Minen, Technical Director, VI-grade. “We are now fine tuning a new revolutionary Multi-Cueing technique to harmonize platform motions and somato-sensory cues in order to expand the virtual immersion to an unprecedented level of realism. We are looking forward to cooperate with Volvo in order to further improve our driving simulation technology!”
Volvo has announced back in October 2015 the installation of the revolutionary 9 degrees-of-freedom DiM® platform developed by VI-grade and its partners and has since then used it extensively in the development process of new vehicles, such as the S90. The DiM® concept enables the extension of the motion envelope and the separation of low and high frequency contributions, which makes this type of motion platform unique and suitable for both vehicle dynamics and ride studies.
The YouTube video of DiM installed at Volvo is available at this link.
The revolutionary driving simulation turnkey solutions from VI-grade provide automotive engineers with a complete set of innovative, integrated driving simulators for a new generation approach to system-level simulation, allowing companies to bridge the gap between virtual prototyping and testing. VI-DriveSim provides the ability of "feeling" the results of your simulations in a totally immersive environment starting from early phases of the development process. Our driving simulation solutions are available in two different configurations: static and dynamic. The driving simulation solutions from VI-grade are based on VI-DriveSim, the product which provides the core software environment for all driving simulation solutions from VI-grade.
Marburg, January 10th, 2017 – VI-grade today announced that the Würzburg Institute for Traffic Sciences (WIVW), Bayern-based company providing services in the field of human factors, developed an advanced motorcycle riding simulator, relying on VI-grade technology. The development of this dynamic motorcycle riding simulator was part of the ZIM funded project DESMORI, supported by the Federal Ministry for Economic Affairs and Energy (KF 2012453RP3; partners: TU Darmstadt (FZD) and BMW Motorrad). In particular, the simulator is taking advantage of the real-time VI-BikeRealTime motorcycle simulation software from VI-grade and, besides for HMI-design, it will be used for rider training as well as research on rider behavior in a broader sense (e.g. hazard perception or implementation of an autonomous brake assist).
“The first motivation to develop an advanced motorcycle riding simulator at WIVW was the implementation in the human factors research and development process” said Sebastian Will, Project manager focusing on powered two-wheeler research, WIVW. “The simulator as research tool allows assessing human-machine interfaces for powered two wheelers in a safe and controlled environment. This extends WIVW’s long-standing human factors experience from the automotive to the motorcycle sector.”
“In order to draw appropriate conclusions from simulator studies, the riders shall find conditions in the laboratory that support them in showing naturalistic behavior: therefore, a simulator needs to meet the riders’ expectations in terms of riding dynamics” concluded Will. “WIVW has chosen VI-BikeRealTime 2016 with a Co-simulation with Matlab/Simulink to solve this. The VI-grade software made it easy to de-couple the VI-rider model from the simulated motorcycle in order to feed the model with the real riders’ input, whereas the Matlab/Simulink co-simulation offered variability regarding additional controller implementation (e.g. stabilization systems, input determination and motion cueing).”
“We are extremely happy to report this activity at WIVW, because it clearly shows the versatility of our software solutions as well as our competence as a team in supporting the development of real-world simulators, not only for the automotive industry”, said Juergen Fett, Managing Director, VI-grade. “We are looking forward to further supporting WIVW and their partners in their exciting and challenging activity.”
VI-BikeRealTime is a modeling, post processing and real-time analysis environment for motorcycle models which allows designers, analysts and track engineers to take into account effects from the motorcycle itself as well as from the road profile and the rider. VI-BikeRealTime is also the ideal platform to perform software-in-the-loop and hardware-in-the-loop activities on a motorcycle model. This is made possible thanks to the interface with MATLAB Simulink and with most widely used HIL platforms. In this way, engineers can first develop reliable control systems in a safe environment and then test them checking how real ECUs interact with the virtual model. ECUs durability under realistic working conditions can be tested as well. VI-BikeRealTime is interfaced with VI-Motorcycle, the ADAMS-based multibody solution for detailed motorcycle models, and therefore real-time models can be automatically derived from detailed multibody models. This approach, already proven to be successful in the automotive industry, allows users to decrease modelling time, to increase confidence in results and to maintain only one database. VI-BikeRealTime has been proven to deliver reliable results in several different projects with leading motorcycle manufacturers. Despite of the fact that the model is simplified, results match very well experimental measurements.
SILAB is a driving simulation software that allows driver-in-the-loop testing of vehicle components in a realistic virtual environment. It offers tools to design traffic scenarios by modelling complex road networks and traffic behavior. The scenarios can be flexibly combined to form reproducible test tracks. During simulation, high quality image rendering and a realistic sound simulation create an immersive impression for the driver. The software supports simulator setups starting from simple desktop systems up to driving simulators with multiple image channels, motion systems and real vehicles as mockups. User defined software and hardware components can be integrated into the driving simulation via common communication protocols (e.g. TCP/IP, CAN-Bus) or by using a flexible SDK. Thereby, SILAB offers detailed access to information on all aspects of the virtual world, e.g. road data, simulated traffic and surrounding objects. All data that is created or measured by the software can be recorded time synchronously. SILAB is used in the fields of R&D, training, medical diagnostics and rehabilitation.
