본 발명은 차량용 직렬 유압 하이브리드 시스템(1)에 관한 것이며, 그 시스템은, 제2 유압 변위 유닛(7)과 유체 연통하는 제1 유압 변위 유닛(6)을 포함하는 유압 회로(2), 유압 엑추에이터(4), 및 유압 어큐뮬레이터 어셈블리(5)를 포함하며, 여기서, 유압 어큐뮬레이터 어셈블리(5)는 적어도 하나의 제어가능한 회로 밸브(12a, 12b, 13a, 13b)에 의해 유압 회로(2)와 선택적으로 유체 연통하고, 그리고 유압 어큐뮬레이터 어셈블리(5)는 적어도 하나의 제어가능한 엑추에이터 밸브(17a, 17b)에 의해 유압 엑추에이터(4)와 선택적으로 유체 연통하여, 유압 어큐뮬레이터 어셈블리(5)가 적어도 하나의 회로 밸브(12a, 12b, 13a, 13b)의 제어 위치와 독립적으로 적어도 하나의 엑추에이터 밸브(17a, 17b)에 의해 유압 엑추에이터(4)와 선택적으로 유체 연결되고 유압 엑추에이터(4)로부터 선택적으로 유체 연결해제되도록 구성된다. 본 발명은 또한 시스템(1)을 동작시키는 방법에 관한 것이다.

    The invention relates to a series hydraulic hybrid system (1) for a vehicle, comprising: a hydraulic circuit (2) comprising a first hydraulic displacement unit (6) in fluid communication with a second hydraulic displacement unit (7), a hydraulic actuator (4), and a hydraulic accumulator assembly (5); wherein the hydraulic accumulator assembly (5) is selectively in fluid communication with the hydraulic circuit (2) by means of at least one controllable circuit valve (12a, 12b, 13a, 13b), and wherein the hydraulic accumulator assembly (5) is selectively in fluid communication with the hydraulic actuator (4) by means of at least one controllable actuator valve (17a, 17b), such that the hydraulic accumulator assembly (5) is configured to be selectively fluidly connected with and to be selectively fluidly disconnected from the hydraulic actuator (4) by means of the at least one actuator valve (17a, 17b) independently of a control position of the at least one circuit valve (12a, 12b, 13a, 13b). The invention further relates to a method of operating the system (1).
