Electro-Hydraulic Steering System and Method An electro-hydraulic steering system (1) includes a steering wheel (2) for setting a steering demand and a hydraulic steering actuator (11) for turning the steered wheel in response to the steering demand. An electrically controlled hydraulic valve (26) is arranged to supply pressurised fluid to the hydraulic steering actuator to turn the steered wheel according to a variable steering ratio. An electronic control unit (21) receives an angular position of the steering wheel and an angular position of the steered wheel. The control unit is operative to determine an angular misalignment between the steering wheel and the steered wheel and carry out a realignment procedure. The realignment procedure comprises calculating a compensation angle based on the angular misalignment and controlling the steering ratio based on the compensation angle by controlling the hydraulic valve to adjust the supply of pressurised fluid to the hydraulic steering actuator.
