摘要： PROBLEM TO BE SOLVED: To provide a technology capable of suppressing the dragging of an unnecessary brake when performing regenerative cooperation control.
SOLUTION: In this brake control device, a regenerative brake unit 10 generates a regenerative braking force by the regenerative control of an electric motor. A hydraulic brake unit 20 generates a hydraulic braking force by the hydraulic control of a working fluid. A control part controls the regenerative brake unit 10 and the hydraulic brake unit 20 to satisfy a target braking force calculated according to a brake operation of a driver, and calculates the hydraulic braking force being a target by subtracting the executed regenerative braking force from the target braking force. An error suppressing part suppresses an error generated by the processing of a figure smaller than a minimum unit to be used in a process for calculating the regenerative braking force.

摘要： PROBLEM TO BE SOLVED: To provide a braking device for a vehicle, suitably setting a warning area related to drop of accumulator pressure and reducing unnecessary warning especially in a low vehicle speed region.
SOLUTION: In this braking device for a vehicle, the braking force is increased by hydraulic fluid pressure (brake fluid pressure) accumulated in a pressure accumulating device such as an accumulator, and according to the pressure in the pressure accumulating device, predetermined disposition such as warning or control inhibition is performed. When the pressure in the pressure accumulating device becomes a threshold pressure or less, which is determined on the basis of the quantity of hydraulic fluid required for generating a desired decelerated speed, the above predetermined disposition is performed. Further, while controlling no brake, or when predetermined wheel cylinder pressure is secured in each wheel even in controlling the brake, the above predetermined disposition is not performed even if the pressure in the pressure accumulating device becomes the above threshold pressure or less.

摘要： PROBLEM TO BE SOLVED: To suppress reduction in an operating fluid supplied to a master cylinder due to reduction in the operating fluid in a reservoir tank. SOLUTION: In the brake control device 10, a reservoir switch 60 detects the reduction in the operating fluid in the reservoir tank 26.
