Abstract
An actuator apparatus includes a booster creating an infinite boost ratio while a plunger valve does not contact with a reaction disc, and an oil reservoir and a pedal simulator unit forming a hydraulic circuit to follow hydraulic hysteresis characteristics. Therefore, it is possible to achieve insensibility of pedal changes transmitted from a master cylinder, minimize changes in pedal feel according to changes of pedal effort correspondingly generated, while blocking vibration transmitted to the pedal when achieving regenerative braking, and provide pedal feel following or simulating the hydraulic hysteresis characteristics.
