The researchers and engineers are in constant seek for the improvement of the vehicle ride performance to meet the customers' needs. One of the ideas was the introduction of inerter, as a two-terminal device, that has a potential to improve the ride comfort of the vehicles. However, with the increased use of automobiles one more challenge has occurred which is the energy consumption that has led to a lot of energy wasted in the form of heat, noise, or undesired vibrational motions. As a result, engineers came up with the idea of energy harvesting from vehicle's suspension system. In this study, energy harvesting of active suspension vehicles is examined. The novel aim is to show the energy harvesting potential of the inerter by using two different inerter-based quarter car suspension systems. Additionally, fuzzy logic controller (FLC) is designed for the quarter car suspension model with and without inerter in order to increase the ride comfort of the vehicle. In order to verify performance characteristics, inerter-based passive and FLC active suspension systems were compared with classical passive suspension and FLC-based active suspension systems without inerter. The time and frequency responses demonstrated that the ride comfort was increased at most by the inerter-based FLC case. For the active suspensions involving an inerter, the proposed FLC decreased the vehicle body acceleration up to 69% and 85% for chirp and bump road inputs, respectively. Additionally, it revealed that the use of FLC has increased the amount of energy harvested. Finally, with the use of the FLC the ride comfort improvement was achieved while providing the quarter car model a potential to harvest energy from the inerter-based suspension.
