Made for the development of a unique steering feel

MXsteerHiL: Experience, evaluate and calibrate steering systems and ADAS/AD in the early phase.

The requirements for testing and validating steering systems are increasing with the future of assisted and automated driving. Above all, steering feel is crucial. A steering-in-the-loop solution provides a uniquely realistic steering feel for vehicle dynamics and automated driving even in the early stages of development.

For the steering test bench, it is irrelevant whether it is a conventional steering system or a steer-by-wire steering system. Difficulties are identified at an early stage in virtual development, not just in the real vehicle, which always involves a great deal of effort and additional costs. Experiencing the real steering feel for engineers and customers is the key to effective development of steering systems and ADAS/AD functions. MXsteerHiL creates the bridge between steering and ADAS/AD systems and functions.

MXsteerHiL – an indispensable tool in agile development

MXsteerHiL is a highly dynamic, real-time HiL test bench for (EPS) steering systems – as a modular construction kit. This is the result of our many years of research and development work in cooperation with the universities of Munich and Kempten. This steering test bench can be used flexibly from the HiL laboratory to the highly dynamic simulator. It can be used to evaluate and calibrate steering systems and ADAS/AD functions at an early stage of development. Such a closed-loop steering test bench ensures the development of a unique steering feel for each steering system. Creative ideas can be implemented more efficiently and show results more quickly.
