In this study, the suspension system used the hydraulic-harvester technique with a controllable valve to maintain good dynamics performance of passenger vehicles and harvest the energy of the road vibrations. The full vehicle model with nonlinear behaviour for springs and dampers is used as a case study when subjected to random excitations. The dynamic performance of the hydraulic-harvester suspension was compared with the passive, full-active hydraulic and full-active electric suspensions system using MATLAB/Simulink software. The PID control strategy is used to control the spool valves of the hydraulic-harvester suspensions for maintaining the dynamic performance of hydraulic-active suspensions systems to harvest the kinetic energy of road ripples. The results showed that dynamic responses of the hydraulic-harvester suspension system achieve good performance and harvest the energy of vibrations comparative to full-active suspension systems.
