Multi-mode Design and Constant Current Control of Hydraulically Interconnected Energy-Regenerative Suspension
This work develops a half-car model based on hydraulically interconnected energy-regenerative suspension(HIERS)to analyze the vehicle dynamic performances and energy-regenerative characteristics under three working modes of comfort,security and energy-feedback.Also,a multi-mode control system is proposed based on the constant current control method.Taking the road excitation frequency as the multi-mode system switching threshold,a comprehensive investigation on the vehicle dynamic performances is performed.According to the simulation results,it can be found that a 10.77%decrement of body acceleration can be reached under the comfort mode compared with comprehensiveness mode.Apart from that,tire dynamic load under security mode drops by 17.43%and theoretical energy-regenerative power under energyfeedback mode increases by 19.48%.The conclusion proves that the coordinated control of HIERS dynamic performance and energy-regenerative characteristics is achieved.
