Abstract To enhance the performance of the hydraulic electric energy harvesting suspension, several steps were taken. Firstly, a resistance feedback control strategy was proposed in this paper based on the controllable damping characteristics. Subsequently, a model of the suspension was established based on its structure and working principle. And a simulation model was created, the tracking effect of current as well as the enhancement of suspension performance, were investigated to preliminarily validate the effectiveness of the control strategy. Finally, a bench test was conducted to verify the proposed strategy. Experimental results demonstrated that the peak harvesting can reach about300 W, and the average is 190.3 W. The vertical acceleration of the body in the hydraulic electric energy harvesting suspension decreased by 18.01% when employing the control strategy compared to the passive suspension.
