The present invention relates to a vehicular brake driving device for receiving a speed-reducing control signal from a traveling control unit of an autonomous vehicle, receiving a status signal that follows the vehicle's operating status, and pressurizing the brake pedal or releasing the pressurization, thereby reducing the speed of the autonomous vehicle. According to the present invention, a control module rotates/drives a driving module with reference to a driving reference rotation angle of the driving module such that the degree of pressurizing the brake pedal can be accurately adjusted according to a speed-reducing control signal received from the traveling control unit, regardless of the installation height of the brake pedal of the vehicle and the angle and shape of a pressurizing surface, thereby enabling precise speed-reducing control of the autonomous vehicle; the contact point of a driving arm, which contacts the pressurizing surface of the brake pedal by means of rotation/driving of the driving module, is provided in the shape of a convex arc toward the brake pedal such that the driving arm slides along the pressurizing surface of the brake pedal and accordingly pressurizes the brake pedal or releases the pressurization; accordingly, the degree of increase/decrease of the speed-reducing force of the autonomous vehicle, resulting from rotation/driving of the driving module, can become constant, thereby improving the speed-reducing stability of the autonomous vehicle; and the control module sets the driving reference rotation angle of the driving module so as to correspond to the position in which the driving arm does not contact the brake pedal, thereby preventing unnecessary speed reduction that would otherwise occur as the driving arm, which has contacted the brake pedal, slightly pressurizes the brake pedal when no speed-reducing control is required. La présente invention concerne un dispositif d'activation de frein de véhicule qui permet de recevoir un signal de commande de réduction de vitesse d'une unité de commande de déplacement d'un véhicule autonome, de recevoir un signal d'état qui suit l'état de fonctionnement du véhicule et de mettre sous pression la pédale de frein ou de libérer la mise sous pression, ce qui permet de réduire la vitesse du véhicule autonome. Selon la présente invention, un module de commande fait tourner/active un module d'activation par rapport à un angle de rotation de référence d'activation du module d'activation de sorte que le degré de mise sous pression de la pédale de frein peut être réglé avec précision en fonction d'un signal de commande de réduction de vitesse reçu de l'unité de commande de déplacement, indépendamment de la hauteur d'installation de la pédale de frein du véhicule et de l'angle et de la forme d'une surface de mise sous pression, permettant ainsi d'obtenir une commande précise de réduction de vitesse du véhicule autonome ; le point de contact d'un bras d'activation, qui entre en contact avec la surface de mise sous pression de la pédale de frein au moyen de la rotation/de l'activation du module d'activation, présente la forme d'un arc convexe en direction de la pédale de frein de sorte que le bras d'activation coulisse le long de la surface de mise sous pression de la pédale de frein et met par conséquent sous pression la pédale de frein ou libère la mise sous pression ; par conséquent, le degré d'augmentation/de réduction de la force de réduction de vitesse du véhicule autonome, résultant de la rotation/de l'activation du module d'activation, peut devenir constante, ce qui permet d'améliorer la stabilité de réduction de vitesse du véhicule autonome ; le module de commande règle l'angle de rotation de référence d'activation du module d'activation de manière à correspondre à la position dans laquelle le bras d'activation n'entre pas en contact avec la pédale de frein, ce qui permet d'éviter la réduction de vitesse non nécessaire qui se produirait autrement lorsque le bras d'activation, qui est entré en contact avec la pédale de frein, met légèrement sous pression la pédale de frein lorsque aucune commande de réduction de vitesse n'est requise. 본 발명은, 자율주행차량의 주행제어유닛으로부터 수신된 감속 제어신호와 차량의 작동상태에 따른 상태신호를 수신하여, 브레이크 페달을 가압하거나 가압을 해제하여 자율주행차량의 감속을 수행하는 차량용 브레이크 구동장치에 관한 것이다. 본 발명에 의하면, 제어모듈이 구동모듈의 구동기준 회전각을 기준으로 구동모듈을 회전 구동시킴으로써, 차량의 브레이크 페달의 설치 높이, 가압면의 각도 및 형태와 상관없이, 주행제어유닛으로부터 수신한 감속 제어신호에 따라, 브레이크 페달의 가압정도를 정확하게 조절할 수 있어, 자율주행차량의 정밀한 감속제어가 가능하고, 구동모듈의 회전구동에 의해, 브레이크 페달의 가압면과 접촉하는 구동 암의 접촉지점이 브레이크 페달 방향으로 볼록한 호 형상으로 마련되어, 구동 암이 브레이크 페달의 가압면을 따라 슬라이딩되면서 브레이크 페달을 가압하거나 가압을 해제시키기 때문에, 구동모듈의 회전 구동에 의한 자율주행차량의 감속력 증감폭이 일정해질 수 있어, 자율주행차량의 감속 안정성이 증대될 수 있으며, 제어모듈이 구동 암이 브레이크 페달과 접촉되지 않은 위치에 대응되도록 구동모듈의 구동기준 회전각을 설정함으로써, 감속 제어가 요구되지 않을 때, 브레이크 페달에 접촉된 구동 암이 브레이크 페달을 미세하게 가압함으로 인해 발생하는, 불필요한 감속을 방지할 수 있는 효과가 있다.
