With a view to promote mobility electrification, improved comfort and handling with lower cost are crucial factors in next generation of EV and HEV design. In contrast to ICE platform, electrified counterparts displays distinct NVH characteristics that present challenges in terms of weight transfer, steering, motor vibrations, etc. From a holistic perspective, this paper proposes a compounded suspension system serving dual purpose of dynamic damping and power rejuvenation utilizing electric motor as part of the tuned mass damper inertia system. A variable inertance mechanism is developed in form of geartrain while motor vibration itself receives calculated harness through tuned mass damping. Furthermore, suspension deformation undergoes desirable mitigation as a result of effective simulated annealing optimization focused on shifting objective value according to input tradeoff prediction. Nonlinear system dynamics are considered as a means to broaden the damping bandwidth. Besides power regeneration through storage medium, this paper proposes an alternative method of direct energy transition from collection port to shaft, which provides robust torque assist and response. Utilizing tuned motor suspension, vehicle body movements are counteracted by collaborative motor damping and adjustable in-situ shock absorbers, in return improving maneuver stability. The suspension system is validated through numerical simulation in a full car model. The simulation results indicate that the studied model is capable of vertical acceleration attenuation of 27% and harvesting efficiency of 58% in regeneration mode while producing lower wheel chassis oscillation by 31%. The results show that, owing to the presence of coupled motor activation, the proposed suspension outperforms the existing control methods in terms of both passenger comfort and tire grip.
