Continentals New Driving Simulator

Test tyres without building them first

Testing tyres without building them? Sounds like a dream of the future? Not at Continental Tyres. At our Contidrom test site. situated in Jeversen near Hanover, we have a driving simulator in operation that can do just that.

One-Year test phase successful

After an intensive test phase of around a year, Continental has now put the so-called driver-in-the-loop simulator into operation. Development times and raw materials in production, as well as the associated logistics can be reduced significantly with the help of the simulator.

The experts Julian Kröber (from left), Kai-Uwe Köhne and Carsten Schröder can view and evaluate driving data in real time.

Powerful servers are required so that the simulator can simulate a test drive.

From the outside, the building does not reveal what is hidden behind the walls: the high-tech driver-in-the-loop simulator.

Virtual development methods enable us to offer solutions even more efficiently and more precisely tailored to the needs and requirements of our customers. Virtual test kilometers also play a major part in conserving valuable resources.

Three advantages in one fell swoop

The driving simulator allows a tyre to be tested and optimised before it is even physically built. This has several advantages:

Saves Time

The virtual tests in the simulator can save several months in the development process. This also saves our customers a lot of time.

Tests Materials

New materials that are used in a tyre for the first time can be extensively tested in the simulator. During the process, properties and interactions with other materials in the tyre are thoroughly investigated.

Saves Ressources

Each test cycle in the driving simulator means fewer physical test patches. In this way, the use of raw materials in the context of production and logistics are minimised. This new test technology also contributes to our extensive sustainability activities.

This is what our driving simulator looks like in action...

... and this is how it works:

The simulator calculates the exact driving dynamics parameters for the tyres and the corresponding test vehicle. Continental loads the relevant tyre model for the customer’s specific vehicle into the simulator. The tyre model contains precise information on the tyre design, tread and rubber compound. The test driver thus drives a dedicated tyre model for a specific vehicle model variant, as was previously the case on the physical test track. Tyres for all vehicle and drive variants, for passenger cars and commercial vehicles, for electric, hybrid and combustion-engine vehicles can be evaluated in the simulator. The crucial advantage is that the tyre parameters can be adjusted digitally at any time. This means that test drives can be repeated at short intervals and subjective impressions can be compared directly with each other.

Thanks to its motion platform that measures four meters in length and five meters in width and features a maximum acceleration of twelve meters per second, the test drivers feel all six degrees of freedom of the vehicle dynamics. Just like in a vehicle on the test track. These include the longitudinal and lateral movements, the stroke movement, the yaw, pitch and roll of a vehicle. Professional test drivers are trained to incorporate these subjective driving impressions into the development process. This experience is essential for achieving the exact tyre set-up required by the vehicle manufacturers for the particular vehicle model.
