Hydraulic architecture strategies

Researchers compare two different rule-based power-management strategies, in terms of their resultant fuel consumptions, through a simulation study as applied to a hybrid hydraulic multi-actuator displacement controlled system.

In recent years there has been a thrust toward improving the fuel and energy efficiencies of both passenger vehicles and off-highway equipment, driven by rising fuel costs and stricter emissions laws.

Research into these systems has involved operation of the energy source (engine) at more efficient operation points through power management, as well as transmission mechanisms for recovery and capture of energy. Electric hybrids that use batteries and capacitors for energy capture and storage, as well as hydraulic hybrid mobile machines that use accumulators for energy storage, have been studied toward this end.
