Abstract

The principle of energy-saving in hydraulic hybrid vehicles was introduced. The characteristics of hybrid vehicles with electric or hydraulic were compared. Because of its higher power density and higher efficiency, hydraulic hybrid vehicle is more advantageous when working under the condition changed frequently such as city bus. Different arrangement forms of the hydraulic hybrid system were analyzed to explore their own characteristics and applications. Based on the batteries with high energy density and hydraulic accumulators with high power density, a kind of combination that include their respective advantage were proposed.
