This paper proposes a rotary electric actuator for an active suspension system that controls movement in the roll, pitch, and bounce directions of the vehicle. The efect of sky-hook and inertia control on vehicle performance was then clarified. This paper also describes the effects of the actuator from standpoints of responsiveness and consumption energy of the active suspension system. Targets were set for the typical performance indicators of an active suspension system: (1) displacement ratio for ride comfort, and (2) roll rate for vehicle stability. In addition, clarifying the evaluation conditions for these targets enabled performance requirements for the electric stabilizer and logic for ride comfort control to be proposed based on the results of verification tests performed in an actual vehicle and by simulation. As a result, the amount of power required by the system was substantially reduced over that of a conventional hydraulic active suspension system by lowering energy consumption and by using current generation. For the future, there is a need to promote further reduce energy consumption by technical development of software and hardware, leading to the creation of an electromagnetic suspension system that will more effectively utilize generated current.
