Hydraulic steering system

A hydraulic steering system (1) is described, the system (1) comprising a steering command device (2) with a steering sensor (3), a steering motor (6), a wheel sensor (9), a pressure source (P) and a control device (12) that controls the supply of fluid from the pressure source (P) to the steering motor (6), where the control device (12) comprises an open loop controller (19). Such a steering system should have a good relationship between the steering input from the operator and the steering behavior of the vehicle to be steered. To this end, in addition to the open-loop controller (19), the control device (12) further comprises a closed-loop controller (20), in which a cross-conversion device (21) is provided, which is connected to the open-loop controller (19) and the closed-loop controller (20) and controls the conversion between the open-loop controller (19) and the closed-loop controller (20). 描述了一种液压转向系统(1)，该系统(1)包括：具有转向传感器(3)的转向命令装置(2)、转向马达(6)、车轮传感器(9)、压力源(P)和控制装置(12)，该控制装置控制从压力源(P)到转向马达(6)的流体供应，其中，控制装
