The present invention relates to a haptic control device for touch buttons. More specifically, since a sensor microcomputer, which determines whether a touch surface is touched based on the level of an electric signal outputted from a touch sensor, and then, outputs a PWM-modulated haptic control signal for haptic function control when the touch surface is determined as touched as a result of the determination, is formed, the haptic control device for touch buttons can control vibration patterns of a vibration generator by varying the frequency and pulse width modulation of the haptic control signal, and, through these functions, can output haptic control signals of different patterns in response to each touch sensor installed on the touch surface to enable a user to feel vibrations of different patterns for each touch area of the touch surface. The present invention includes: an air conditioning control panel installed in a vehicle; a touch button bracket having a touch surface; and a touch sensor attached to the inside of the touch surface.
본 발명은 터치 버튼용 햅틱제어장치에 관한 것으로서, 더욱 상세하게는 터치센서에서 출력되는 전기신호의 레벨을 이용하여 터치면 터치여부를 판단하고, 그 판단결과 터치면 터치라고 판단되었을 때 햅틱기능제어를 위한 PWM 변조된 햅틱제어신호를 출력하는 센서마이컴을 구성하므로서, 햅틱제어신호의 주파수와 펄스폭변조량을 가변시켜 진동발생체의 떨림 패턴을 조절할 수 있으며, 이러한 기능을 이용하여 터치면에 설치되는 각각의 터치센서에 대응하여 각기 다른 패턴의 햅틱제어신호를 출력하여 사용자가 터치면 터치 영역별로 각기 다른 패턴의 진동을 느낄 수 있도록 한 터치 버튼용 햅틱제어장치에 관한 것이다.
