Abstract
There is provided a vehicle brake device that includes hydraulic brake means for generating a hydraulic brake force and regenerative brake means for generating a regenerative brake force and distributes the hydraulic brake force and the regenerative brake force for a driver-requested brake force. The hydraulic brake means includes a pressure reducing valve that reduces hydraulic pressure of wheel cylinders. The vehicle brake device includes hydraulic brake control means for maintaining the pressure reducing valve open while the driver-requested brake force is covered by only the regenerative brake force. The hydraulic brake control means does not open the pressure reducing valve when hydraulic pressure is present in the wheel cylinders.
