This paper proposes a new haptic cue device for vehicle accelerator pedal utilizing magnetorheological (MR) fluids. As a first step, an MR fluid-based haptic device is devised to be capable of rotary motion of accelerator pedal. Under consideration of spatial limitation, design parameters are optimally determined to maximize control torque using finite element analysis. The proposed haptic cue device is then manufactured and integrated with accelerator pedal. Its fielddependant torque is experimentally evaluated. Vehicle system emulating gear shifting is constructed in virtual environment and communicated with the haptic cue device. The time responses of the manufactured haptic device are then experimental evaluated. Haptic cue algorithm using the feed-forward control algorithm is formulated to achieve optimal gear shifting in driving. Control performances are experimentally evaluated via feed-forward strategy and presented in time domain.
