A integrated steering and braking system for autonomous vehicles

The present invention relates to an integrated steering and braking system for an autonomous vehicle, in which a steering system and a braking system are configured in one assembly. More specifically, the integrated steering and braking system for an autonomous vehicle comprises: a main base member which has a first mounting portion and a second mounting portion formed in the center and on one side so that a steering force transmission portion of the steering system is inserted and fixed, wherein the main base member is fixed to and installed on a vehicle body; a driving pulley which is inserted into and installed on the inside of the first mounting portion such that rotation is made by receiving a rotational force from a steering force generating portion which generates a steering force using a control signal transmitted from a sub-controller or an autonomous driving controller by being fixed to and installed on an upper surface of the first mounting portion; a driven pulley which is installed on the second mounting portion while maintaining a horizontal state with the driving pulley and spaced apart from the driving pulley at a predetermined interval, and through which a steering column is installed in a vertical direction at the center of the driven pulley; a drive belt which is installed horizontally through the inside of the base member between the first mounting portion and the second mounting portion so as to transmit the rotational force of the driving pulley to the driven pulley; a braking system fixing base which is fixed to and installed on one side of the base member and is formed with a fixing piece having a braking force generation portion fixed and installed at an upper end portion to protrude therefrom; and a brake link which presses or releases a brake pedal according to the rotation of the braking force generation portion which is rotated by the control signal transmitted from the autonomous driving controller or the sub-controller, by having one end coupled to an output shaft of the braking force generation unit protruding from one side of the fixed piece of the brake system fixing base, and the other end located on an upper surface of the brake pedal. According to the present invention, precise control of the autonomous vehicle is possible. 본 발명은 조향장치와 제동장치가 하나의 어셈블리로 구성되는 자율주행차량의 일체형 조향 및 제동장치에 관한 것으로, 더욱 상세하게는 조향장치의 조향력전달부가 삽입 고정되도록 중심부 및 일측면부에 제1장착부와 제2장착부가 형성되어 차체에 고정 설치되는 메인 베이스부재; 상기 제1장착부의 상면에 고정 설치되어 자율주행제어기 또는 하위제어기에서 전달된 제어신호로
