Testing big: Vehicle-in-the-loop for trucks

Putting the truck of tomorrow through its paces in terms of safety

Experiencing the functions of a truck’s assistance system during development has never been easier. Whether emergency brake or lane keeping assist systems – real setups and their evaluation are highly complex and their realization involves considerable time and costs. We therefore offer the vehicle-in-the-loop (VIL) method for trucks for you to fuse a real test vehicle with a simulation environment during development and testing.

One package for all requirements

The VIL method, which has long been successfully used for the development of passenger vehicles, has now been adapted to trucks. In order to achieve this, the system was tailored to specific elements from the area of trucks to ensure a convincing representation for a realistic driving experience. Our guiding principle: As everyone has their own specific system, they all need a specific solution. A VIL add-on can therefore be purchased for already existing development simulations which allows the real vehicle to be embedded into the simulation environment in real time. Of course we also offer a realization of the VIL method relating to ADAS functions for you to start testing from scratch. In coordination with you, we will gear the project-specific add-ons (e.g. the realization of the sensor interface) to your requirements.

In the fast lane with virtual test driving

Does the vehicle stay in the lane? Is the emergency brake system working? You or your test driver will sit in a real vehicle, while road markings, oncoming traffic and pedestrians are simulated. This enables you to test in real time how well your system already works, on a proving ground without any risk of personal injury or material damage. The time-consuming and cost-intensive setup of real mock-ups with dummies is also no longer required. At the same time, the simulation not only allows for testing of camera and ultrasonic sensor specifications but also (and especially) radar-based systems, which can be tried in a variety of scenarios.

Why early tests are essential

A high system maturity level of assistance functions is imperative for trucks as these may prevent or at least mitigate severe accidents. Over the past years, a growing number of new safety and assistance systems have been installed in trucks or their use has become legally regulated. Did you know that in Germany, for instance, emergency brake assist systems for trucks have been mandatory since 2015 for all new vehicles from a weight of 8 tons? In a second stage, which will be in force from November 2018, a speed reduction of 20 kmh is required for the systems. Use our software solutions to be ideally equipped for these and other challenges.
