페달 시뮬레이터 다물체동역학 해석

Abstract

Pedal simulator is a device for the human-machine interface. So to speak, the braking intention of driver transfers to the electro mechanical brakes through pedal simulators. On the other hands, if the pedal simulator’s response is different from traditional hydraulic brake’s response such as the relation of strokes and reaction forces, then the driver feels inconvenient and anxiety. Therefore, it is important for the pedal simulator to get the similar response of hydraulic brake pedal. There are some approaches such as active type and passive type to implement pedal feel of pedal simulator. Passive type consists of mechanical springs and dampers. Therefore, the passive type is more cost-effective than the active type. In this paper, we describe a mechanism concept of passive type with multi-body dynamics simulation.
