CEVT adopts VI-grade DiM250 Dynamic Driving Simulator

Chinese car manufacturer to open European vehicle technology centre with Driver-in-Motion dynamic simulation technology

The Geely owned China Euro Vehicle Technology centre (CEVT) based in Sweden is taking a “Dynamic” Driving Simulator from VI-grade to enhance its research and development capabilities.

The DiM250 (Driver-in-Motion) Dynamic Driving Simulator is equipped with the whole VI-DriveSim software suite and with active technology (belts, seat, brake and shakers) that will be installed in the to-be-built second part of Geely’s campus at Lindholmen, which is planned to be completed in the summer of 2021.

The driving simulator will be used for Vehicle Dynamics, Ride & Comfort as well as ADAS applications in the development of new vehicles.

Owned wholly by Geely, the CEVT is engaged in all the main aspects of passenger car development – from architecture to powertrain and driveline components, to structural engineering and body design. The company created the innovation centre for the development of future cars for Geely.

“For CEVT, this investment is a crucial part of our toolbox to develop future mobility concepts. It shows the importance of CEVT as a company within the Geely Auto Group as well as a company in the automotive capital of the Nordics”, said Mats Fägerhag, CEO at CEVT.

“Our ambition with the simulator is to replicate the real world in as many aspects as possible to provide our engineers with an alternative to real world tests. In many cases we see that we can do the same tests as in the real world and still get a high level of representation of reality. This means that the simulator can be an option to any test that can be done on a prototype vehicle or a test vehicle in general. Examples of such studies can be vehicle dynamics, ride and handling but also research on autonomous cars as well as future transport and mobility. Anything that can be modelled on a computer in an accurate manner can be tested”, he says.

According to Albin Gröndahl, CAE Engineer and Project Manager for the Driving Simulator at CEVT, in the past, any new functions had to be designed then a prototype built and a test vehicle before taking it onto a test tract. The design change, modification and retesting process is very iterative and can often take months and cost a lot of money for each and every part of the process.

“With the simulator, you can do a simple model of the function, take it downstairs to the simulator and try it out directly. You also get direct access to all the data and better control of the test. We can probably test our vehicles half a year before we get the prototypes for them,” he says.

The CEVT order is the 20th installation of the Dynamic Driving Simulators (DiM150 and DiM250) globally and the second in the city of Gothenburg, where Volvo’s DiM150 has been operational since 2014.

To reproduce vehicle movements and accelerations, the DiM system takes a different path to driving simulation and is based on a patented design with nine actuators. The resulting configuration with its 9 degrees of freedom enables designers to go beyond the basic six-actuator design of a simple hexapod or similar, thus providing a larger workspace while maintaining a high stiffness. This leads to a system suitable for low as well as high frequencies, both of which occur in automotive chassis design.
