SbW-MRFA

Steer-by-wire with magnetorheological feedback actuator

Prof. Dr. Peter Pfeffer

The main objective of the project is to increase the innovative capacity and sustainability in the program area through the use of the developed MR technology. The focus is on the technological qualification of SMEs. In this technology project, a magnetorheological (MR) brake is connected in parallel with the electric motor, allowing the electric motor to be significantly smaller. This improves control quality, saves energy, weight and costs and reduces resource requirements. The megatrend of automated driving requires new steering technology. Steer-by-wire (SbW) steering systems are therefore set to replace conventional steering systems in new vehicles. These SbW require a feedback actuator to provide the driver with haptic feedback.
