PURPOSE: An electronic hydraulic brake device is provided to lower manufacturing costs and improve the assemblability by minimizing the number of valve parts. CONSTITUTION: An electronic hydraulic brake device (1) comprises a master cylinder part (10), a wheel cylinder part (20), a passage part (30), a valve part (40), an oil pressure control part (50), and a control part (60). The master cylinder part supplies fluid pressure according to the pressurization of a brake pedal (11). The wheel cylinder part is mounted on each wheel of a vehicle and moves a brake pad using fluid pressure. The passage part connects the master cylinder part and the wheel cylinder part and guides fluid pressure from the master cylinder part to the wheel cylinder part. The valve part is arranged in the passage part and controls fluid pressure. The oil pressure control part is connected to the passage part arranged between the valve part and the wheel cylinder part. The control part controls each valve part and the oil pressure control part on the basis of all kinds of vehicle driving information. [Reference numerals] (60) Control part |
