Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braking device used for decelerating or stopping a vehicle and maintaining a parking state. In general, a brake system installed in a vehicle currently operates a brake of a wheel through a hydraulic circuit by a mechanical connection. When the pedal and brake pedal are pressed at the same time, they are transmitted to the brakes as they cause accidents. Also, the electronics that control the operation of the brakes use the additional actuators to control these hydraulic circuits, which leads to a huge increase in the unit cost. In the present invention, the present invention detects the force and speed applied to the brake pedal through a sensor, converts the signal into an electrical signal, and configures a system for driving the brake actuator mounted on the wheel, thereby providing an electric signal. To control the brake It is possible to compensate for the brake operation, it will be one to the brake control without the need for connection of an additional hydraulic circuit.
