  1. 1. Control of a Hydraulic Hybrid System for Wheel Loaders

    University essay from Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Fluida och mekatroniska system

    Author : Christopher Reichenwallner; Daniel Wasborg; [2019]
    Keywords : EMS; Energy management strategy; Rule-based; Hydraulic hybrid; Wheel loader; Construction machinery; SLC; Short loading cycle; Torque converter; Energy recuperation; Energy efficiency; Backward simulation;

    Abstract : In recent years many companies have investigated the use of hybrid technology due to the potential of increasing the driveline’s efficiency and thus reducing fuel consumption. Previous studies show that hydraulic hybrid technology can be favourable to use in construction machinery such as wheel loaders, which often operate in repetitive drive cycles and have high transient power demands.
