Abstract
Though the perceived shift quality for a manual transmission is very important, a useful design framework of the operation feeling has never established. For the sake of simplicity and clarity as possible, we develop the shift operation system with a lock-ball mechanism. The dynamics of shift operation, which results from the interaction between human's arm and the shifter, is discussed. And, the shift operation simulator including a stretch reflex model is developed. Furthermore, we propose a unique approach that is the basic study including neuroscience for the haptic perception phenomena which are concerned with the shift feeling.
