EPSiL
Our HiL steering test bench allows the real-time testing of complete steering systems indoors.
It is designed to test the interaction between the wheel forces, steering functions and human beings in a controlled environment.
It enables human-driven tests into driving simulators or fully robotized tests as a stand-alone unit.
EPSiL applies the steering links forces respecting the vehicle kinematics and dynamics, while the driver handles the steering wheel and the EPS interacts with the virtual vehicle.
Our steering test bench is suitable to develop, tune and validate steering functions in:
- Vehicle dynamics
- Assistance torque
- Steering feel
- ADAS/AD
- FUSA/SOTIF
