High Efficiency Rear Wheel Steering System | 2025 PACE Award Finalist

High efficiency, high precision, compact design

Advantages:

High active force up to 15.5 kN
Low and high st rokes available (up to 58 mm)
Low system weight <9 kg
Low motor torque required because of high efficiency during active operation due to use of PRG
Self locking in safe state (disabled sytem)
Modular platform design
Improved design in terms of acoustics
High accuracy regarding positioning

Steering in opposite direction compared to front steering decreases the turning cycle and increases maneuverability
Steering in opposite direction at low speed increases the agility and improves vehicle dynamics
Steering in same direction at higher speed increases the vehicle stability and improves vehicle safety
Enabler for “driving 2.0”: e.g. if the front wheel steering fails, the rear wheel steering serves as a fallback system to ensure the vehicle trajectory
