Schaeffler Road Wheel Actuator

Schaeffler is developing key components for steer-by-wire systems, such as road wheel actuators.

Advantages

• Ready for automated driving
• Improved safety through decoupling of driver and coordination with other vehicle systems
• Realization of new vehicle dynamic functions by software, e.g. variable gear ratio
• Decoupling and rejection of disturbance from the road
• Packaging and standardization (e.g. left- and right-hand drive) benefits leading to cost saving by the OEM
