One embodiment of a hydraulic regenerative braking system for a vehicle having at least one drive wheel includes first (24) and second (32) hydraulic machines operable as pumps or motors. One of the hydraulic machines operates in conjunction with the vehicle drive wheels, while the other hydraulic machine operates in conjunction with a flywheel arrangement (28) to store and receive energy. The hydraulic machines are connected to each other such that when one is operating as a pump, it provides fluid to the other to operate that machine as a motor. A control system is provided to receive inputs related to the operation of the vehicle, and to control the fluid flow through the hydraulic machines.
