The present invention relates to a haptic device for a steering wheel for a vehicle. The haptic device for a steering wheel for a vehicle according to the present invention, for generating vibration in a steering wheel that changes the direction of travel of a vehicle to inform the driver of a signal in a specific situation, comprises: a steering hub that is coupled to the steering shaft in a form that surrounds a portion exposed to the interior of the vehicle and has a control device built in that applies a control signal to a circuit component; a steering rim that is formed in a ring shape and is arranged around the hub as a portion that is gripped by the driver's hand and is connected to the hub through spokes; and piezoelectric actuators that are installed in the steering rim and are arranged at intervals along the circumference of the steering rim and generate vibration based on an electrical signal by the piezoelectric effect.

    본 발명은 차량용 스티어링휠의 햅틱 장치에 관한 것이다. 본 발명에 의한 차량용 스티어링휠의 햅틱 장치는, 자동차의 진행 방향을 바꿔 주는 스트어링휠에 진동을 발생시켜서 특정 상황에서의 신호를 운전자에게 알려 주기 위한 것으로, 조향축의 차량 내부로 노출된 부분을 감싸는 형태로 그 조향축에 결합되고, 회로 부품에 제어신호를 인가시키는 제어장치가 내장되는 조향허브; 운전자의 손에 의해 파지되는 부분으로, 링 형상으로 이루어져서 상기 허브 둘레에 배치되고, 상기 허브와 스포크를 통해 연결되는 조향림; 및 상기 조향림에 설치되되, 그 조향림의 원주방향을 따라 간격을 두고 배치되고, 압전 효과에 의해 전기적인 신호에 기초하여 진동을 발생시키는 압전 엑추에이터들;을 포함하는 것을 특징으로 한다.
