Steer-by-Wire (SbW) enables advanced features and functionality not possible with traditional steering systems because it replaces the mechanical connection between the steering wheel and the roadwheels with algorithms, electronics and actuators. The resulting system unlocks advanced safety and performance features while opening new possibilities for vehicle light-weighting and packaging flexibility. SbW emulates the “feel of the road,” offers a wide performance range (including sporty, luxury, comfort, etc.) and enhances maneuverability through our dynamic variable steering ratio.
The SbW system is comprised of two main components, the handwheel actuator (HWA) and the roadwheel actuator (RWA), each of which communicates signals to create a next-level connection between the driver and road. The HWA communicates driver inputs to the roadwheels and returns road surface and steering feel feedback to the driver, while the RWA converts the driver’s inputs into roadwheel actuation and communicates roadwheel feedback to the HWA.
