The steering wheel is one of the most important control elements in a vehicle. The most common steering concept today is front-axle electric power steering (EPS), which involves an electric motor to support the driver during steering. In addition, innovative concepts such as rear-axle steering or complete steer-by-wire applications are increasingly being developed. Steer-by-wire systems no longer require a mechanical steering column. All system components are connected by electrical means. To meet your individual requirements, we offer scalable solutions for developing and testing your steering systems and related components. Benefit from our scalable prototyping solutions or our wide range of high-performance test systems.

When it comes to EPS, the assisting motor can be installed on the steering column (column EPS) or on the steering rack (rack EPS).

Challenges

Challenges

Today’s steering systems require electronic control units (ECUs) to manage the interaction between their mechanical, electrical, and electronic components and to ensure safe operation.

In early development stages, SIL testing helps to test new functions, such as lane keeping or automatic parking, and the control algorithms of the electric motor itself. To bring first ideas to life, prototyping platforms are required which provide the interfaces to control the electric motor and the vehicle communication. During HIL testing at the signal level, the ECU can be put to the test in every conceivable situation without real power components. Testing real power electronics requires power HIL systems, which supply real currents and real voltages to emulate the real motor. To achieve full test coverage, all real parts, including the motor or the complete steering mechanics, must be added to the test setup. Dynamic mechatronic test benches are used to apply mechanical load torques or forces.

Our Solutions for Steering Systems

For steering ECUs and steering systems, dSPACE offers a wide portfolio of systems that can be applied throughout the entire development process, from SIL testing and rapid prototyping to testing at the signal level and the power level. Our test systems range from small desktop real-time systems and low-voltage power HIL systems to compact rotary test benches and large, high-performance steering test benches using linear actuators for applications that require maximum dynamics and precision.

Optimized Production Software Development

The central challenges in production software development include the optimization of RAM resources, run time, and integration into the overall system. Furthermore, it must be possible to split the software in such a way that regular software updates are possible. And before the final software release, special validation and often a release process are required.
