The present invention relates to a hybrid hydraulic four-wheel steering apparatus. The hybrid hydraulic four-wheel steering apparatus includes: an axle speed measurement part receiving power directly from a motor or engine of a vehicle, and measuring the driving speed of a first driving axle installed on a front wheel of the vehicle; a hydraulic driving module not receiving power directly from the motor or engine of the vehicle, and provided on a second driving axle installed on a rear wheel of the vehicle; and an assist driving controller generating a control signal for the synchronization control of the first and second driving axles based on speed information measured by the axle speed measurement part. According to the present invention, since a large alteration to the structure of an existing vehicle is avoided by applying an assist driving controller and a hydraulic driving module to an engine-operated or motor-operated two-wheel driving vehicle, the hybrid hydraulic four-wheel steering apparatus is capable of creating a four-wheel driving vehicle facilitating vehicle application, having a compact structure and having an excellent degree of design freedom.

    본 발명은 차량의 엔진 또는 모터로부터 직접 동력을 전달받으며, 차량의 전륜에 설치되는 제1 구동 액슬의 구동 속도를 측정하는 액슬 속도 측정부, 상기 차량의 엔진 또는 모터로부터 직접 동력을 전달받지 않으며, 차량의 후륜에 설치되는 제2 구동 액슬에 구비되는 유압식 구동모듈 및 상기 액슬 속도 측정부에서 측정된 속도 정보를 기반으로 상기 제1 구동 액슬과 제2 구동 액슬의 동기화 제어를 위한 제어 신호를 발생시키는 보조 구동 제어기(Assist Driving Controller)를 포함하는 하이브리드 유압식 4륜 조향 장치에 관한 것이다. 본 발명에 따르면, 엔진식 또는 전동식의 2륜 구동 차량에 유압식 구동모듈과 보조 구동 제어기를 적용하여 기존 차량의 구조를 크게 변경하지 않도록 함으로써 차량 적용이 용이하고, 콤팩트한 구조를 가지며, 설계자유도가 우수한 4륜 구동 차량을 구현할 수 있는 효과가 있다.
