The present invention relates to an electronic hydraulic brake device comprising: a pedal cylinder part; a master cylinder part; a first hydraulic line part; a second hydraulic line part; a hydraulic connection part; and an auxiliary hydraulic part. The pedal cylinder part generates hydraulic pressure by pressurizing a pedal. The master cylinder part senses the pedal and generates hydraulic pressure by the drive of a motor. The first hydraulic line part is connected to one end of the master cylinder part and guides the hydraulic pressure to the first wheel cylinder part mounted on one of two front wheels and one of two rear wheels, respectively. The second hydraulic line part is connected to the other end of the master cylinder part and guides the hydraulic pressure to a second wheel cylinder part mounted on the other one of the two front wheels and the other one of the two rear wheels, respectively. The hydraulic connection part connects the first hydraulic line part and the second hydraulic part. The auxiliary hydraulic part has one end connected to the pedal cylinder part and the other end connected to one of the first hydraulic line part and the second hydraulic line part to guide the hydraulic pressure. When the hydraulic pressure is not smoothly supplied by the master cylinder part, the hydraulic press is supplied through the auxiliary hydraulic part, thereby improving stability in braking. |
