Key Facts
Up to AD Level 5Enabler for dormant and stowable steering wheelsEasy integrationPackaging freedom: no intermediate shaft, less variantsEnhanced safetyIntegration into Vehicle Motion Control
Steer-by-Wire (SbW) removes the mechanical link between hand wheel and road wheels.
The steering demand is determined by
a) driver input to the steering wheel and/or
b) by an Automated Driving or Vehicle Motion Control system
and is electronically communicated to a Front Axle Actuator (FAA) positioning accordingly.
To measure the driver steering intention and to provide haptic feedback a Hand Wheel Actuator (HWA) can be integrated in the upper steering column.
