Abstract
A method of supplying driving energy to subassemblies of a vehicle having an engine, a braking system including a brake pedal, a hydraulic machine, a hydraulic accumulator and a clutch having an engaged state for connecting the engine to the hydraulic machine for driving the hydraulic machine from the engine and a disengaged state for disconnecting the engine from the hydraulic machine. The method includes the following steps: supplying the subassemblies with the required driving energy at least indirectly from the hydraulic accumulator in a disengaged state of the clutch as long as a predetermined sufficient hydraulic pressure prevails in the hydraulic accumulator; driving the hydraulic machine by the engine in an engaged state of the clutch as long as a pressure prevailing in the hydraulic accumulator is less than the predetermined sufficient hydraulic pressure for supplying the subassemblies with the required driving energy at least indirectly from the engine and for simultaneously charging the hydraulic accumulator by the hydraulic machine with hydraulic fluid until the predetermined sufficient hydraulic pressure in the hydraulic accumulator is reached; and for performing the s…
