ADVANCED HIL SOLUTION WITH PRECISE CONTROL FOR AN OUTSTANDING AND REALISTIC STEERING FEEL
MXsteerHiL: Efficient, realistic and modular solution for steering system, ECU and ADAS development in virtual environments
A Steering-in-the-Loop test bench is the foundation for ensuring an outstanding steering feel and precise function validation throughout the entire development cycle. With MXsteerHiL, you set new benchmarks: the system delivers an exceptionally realistic representation of steering feel – for both conventional and steer-by-wire systems – while enabling early detection of faults and weaknesses.
By integrating steering systems directly into the virtual environment, they can be applied in vehicle dynamics development and linked to ADAS/AD applications. This significantly reduces development effort and costs.
From simulation to reality: Fine-tuning steering systems early in the development process
MXsteerHiL combines a compact, agile design with versatile application possibilities – from high-precision laboratory testing to integration into dynamic driving simulators.
At the heart of this forward-looking technology is the MXsteerAct, a compact and high-performance actuator that delivers precise steering feel and comprehensive HiL functionality. This enables engineers to efficiently validate step by step – from fail-safe tests and functional tests through to performance optimisation and ADAS/AD functionality – while ensuring a true-to-life driving experience.
The proven, cross-component test bench architecture
MXsteerHiL is a HiL test solution for a complete steering system, covering virtually all test cases. It is compatible with all steering systems, including both column-assisted and rack-assisted steering systems as well as steer-by-wire systems.
HiL test bench for steering racks
Example setup 1: HiL test bench for the complete steering system
The steering system is integrated into the test bench in a true-to-original configuration, enabling precise validation under real-world conditions.
At the core are the and the steering wheel actuator MXsteerMot, which together generate an authentic steering feel. All components are controlled via MXsteerCon, which consolidates intelligent, model-based control along with all safety, measurement, power management and communication interfaces into a single central unit.
The result: a powerful, integrated solution for efficient testing, well-founded analysis and accelerated development of modern steering systems.
Example setup 2: static driving simulator with HiL systems
This setup enables integration of static driving simulators with HiL test systems. Using the virtual Driver-in-the-Loop / Hardware-in-the-Loop coupling modules MXsteerLink and MXbrakeLink, steering system and braking functions can be realistically interconnected – for precise testing, well-founded analysis and an authentic driving experience.
The virtual coupling enables seamless switching of the steering feel between the real steering system in the HiL configuration and a virtual steering model.
Example Setup 3: MXsteerHiL Force Increase for Commercial Vehicles
Testing and validation capabilities for electrically and hydraulically assisted commercial vehicle steering systems, with a strong focus on steering feel development and ADAS/AD functions in safe virtual environments.
