Electro-hydraulic brake system and method for controlling the same

The present invention relates to an electronic hydraulic brake unit and a control method, a problem, that is, the weight and the braking force mihwakbo of titration improve the problem of manufacturing costs, and generates pump failure the conventional electromagnetic hydraulic brake device that uses a single pump having to provide the result to address the problems of braking stability and decrease the braking distance increase electromagnetic hydraulic brake unit and a control method which is the main objective. In order to achieve the above objects, a braking input means by which a driver's operation for braking the vehicle; Brake input detecting sensor for detecting a driver's brake input through the brake input device; The pressure generating unit for generating a brake hydraulic pressure; Wheel cylinders of the brake hydraulic pressure generated in the pressure generating portion is transmitted to the braking force generated to constrain the rotation of the wheels; The pressure generating unit and the hydraulic supply line to transfer the connection between the wheel cylinder to the brake hydraulic pressure generated in the pressure generating portion to the respective wheel cylinders; And a brake according to the control signal of the brake to the hydraulic pressure generated and a controller for outputting a control signal for controlling the driving parts of the pressure occurs, and the pressure generating portion, respectively, a controller for a target based on a signal from the brake input detecting sensor the electronic hydraulic brake unit to the brake hydraulic pressure of the hydraulic pressure generated generate characterized in that it comprises an individual main pump and the auxiliary pump is connected to the hydraulic supply line to be passed through the hydraulic pressure supply line, and a control method thereof are disclosed.
