Abstract
A series hydraulic hybrid system for a vehicle is described. The hydraulic hybrid system has a hydraulic circuit and a high pressure accumulator. The hydraulic circuit has a first hydraulic displacement unit in fluid communication with a second hydraulic displacement unit. The high pressure hydraulic accumulator is in fluid communication with the hydraulic circuit and a low pressure hydraulic accumulator in fluid communication with the hydraulic circuit. The high pressure hydraulic accumulator is in fluid communication with the hydraulic circuit through a proportional flow control valve. The proportional flow control valve is adapted to continuously vary a flow of hydraulic fluid between the high pressure hydraulic accumulator and the hydraulic circuit.
