Abstract:

To provide a hydraulic brake device capable of obtaining sufficient braking force even during engine stop.

The hydraulic brake device to be used for a vehicle including a regenerative braking device includes: a pressurization section which pressurizes a brake liquid flowing out of a master cylinder by using a first pump in response to the brake operation of a driver; a hydraulic brake control section including a second pump and capable of controlling a hydraulic pressure per wheel cylinder provided in a wheel by using the pressurized brake liquid; and a hydraulic pressure collecting section which collects the hydraulic pressure corresponding to a braking torque by the regenerative braking device from the wheel cylinder by using the first pump when the regenerative braking device works during the hydraulic braking by the hydraulic brake control section.
