AB - The rapid development of autonomous driving has emphasized the role of swivel seats in maximizing spatial utility and passenger convenience, significantly raising the importance of developing advanced actuation systems. Conventional trapezoidal velocity profiles induce infinite jerk and mechanical shocks due to discontinuities in acceleration. Meanwhile, complex polynomial-based S-curve techniques impose a high computational burden on embedded systems. To overcome these limitations, this paper proposes a single cosine function-based velocity trajectory utilizing a time normalization technique that maps the physical time domain to a phase variable within the interval 0≤t≤π/2. The proposed method ensures the mathematical continuity of both velocity and acceleration, thereby constraining jerk to a finite value. Furthermore, by ensuring that acceleration starts from zero, it fundamentally eliminates initial operational impulses. In particular, because it is formulated as a single mathematical equation, we demonstrate that precise real-time control is achievable even in low-specification Micro Controller Unit (MCU) environments. By suppressing abrupt inertial changes, the proposed method is expected not only to provide passengers with superior ride comfort and psychological stability but also to yield industrial benefits, such as enhanced durability through the reduction of mechanical vibrations.
