Breaking ground: enhancing off-highway machinery simulations with 3D environmental interaction
21 Aug 2025
Off-Highway Evolution Summit - day 2
This paper presents innovative methods to enhance system simulation for off-highway machinery by integrating 3D environmental interaction. A specialized surface contacts library enables realistic modeling of machine-ground contact on uneven terrain, allowing for improved testing of driving maneuvers, trajectory planning and drivetrain efficiency. Additionally, a data distribution service (DDS) interface facilitates seamless communication between simulation tools and 3D environments, enabling virtual testing of automation algorithms, obstacle detection and sensor-based control. These advances significantly broaden the scope of system simulation, making it a powerful tool for developing smarter, safer and more efficient construction machinery.
