Develop, test and validate off-highway vehicles of all types

Off-highway vehicles, such as agricultural and construction machines, are designed for rough terrain, heavy loads, and precise work. The requirements in terms of environmental impact, fuel consumption, and comfort are increasing, as is the use of autonomous and self-driving vehicles across various work processes. Testing the necessary functions early on is essential to achieving maximum safety and efficiency. Virtual prototypes allow for the fully automated testing of vehicles and attachments, streamlining development processes and creating reliable results.

Use Cases

Developing a multi-layer laser scanner for the prevention of accidents

Approximately 55% of accidents involving pedestrians occur when a vehicle is backing up. To reduce such accidents and to improve safety when backing up forklifts, industrial truck manufacturer Linde uses a multi-layer laser scanner (lidar) to monitor the surroundings. The functionality of this scanner in various scenarios (based on ISO 22737) was simulated and tested in a virtual test drive using CarMaker, generating reproducible results that will help prevent dangerous situations and develop safer forklifts.

Virtual driving tests in the agricultural sector: VIL integration of tractors in TruckMaker

The DLG PowerMix is designed for tests in the agricultural field, such as plowing, cultivating, mowing or fertilizing. Conducting tests as early as possible in the development process helps improve reproducibility and allows for adjustments to the vehicle. This can be implemented using the vehicle-in-the-loop method. With TruckMaker, a real tractor can be virtually integrated into a test bench to reproducibly test the scenarios in a virtual environment.
