ReAX Commercial Steering System

TRW introduced its ReAX steering system, which combines hydraulic power steering with electrically powered steering for improved stability and control, at IAA Commercial Vehicles.


TRW Automotive Holdings Corp. has launched the ReAX steering technology which merges two of TRW's proven steering systems – hydraulic power steering (HPS) for commercial vehicles and electrically powered steering (EPS) belt drive for passenger cars – to help improve driver control and stability.

Traditional hydraulic power steering provides the torque required to steer larger commercial vehicles while EPS belt drive offers precision and control

Combining the two technologies reduces steering efforts at low speeds and yields increased stability at higher speeds

Enables semi-automated driving functions and advanced driver assist systems including lane departure warning and lane keeping assist which can further enhance safety and comfort
