Beschreibung
Zusammenfassung:	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).
