Steering control system for hydraulic steering system with a torque sensor for sensing torque applied to a steering input device and hydraulic steering system

Abstract

The disclosure relates to a steering control system (3) for a hydraulic steering system (1) with a steering cylinder (2), wherein the steering control system (3) includes a steering input device (10) operable by an operator for inputting steering commands and a flow adjustment assembly (20) for controlling hydraulic fluid (HFS) supply to the steering cylinder (2) based on the steering commands. In order to provide more precise and comfortable steering, the steering control system (3) includes a torque sensor (13, 15) for sensing torque applied to the steering input device (10), wherein the steering control system (3) is configured to control the flow adjustment assembly (20) based on a torque sensor output (TSO) of the torque sensor (13, 15). The disclosure further relates to a hydraulic steering system (1).
