Abstract
A brake apparatus includes: a master cylinder generating a master cylinder fluid pressure; a wheel brake device applying a braking force to the wheels; a control fluid pressure generation device including a fluid pressure control valve and a fluid pressure pump; an electric motor driving the fluid pressure pump; a control fluid pressure setting unit setting a control fluid pressure; wherein the control fluid pressure generation device rotates the electric motor to circulate a brake fluid and applies a control current to the fluid pressure control valve to thus generate the control fluid pressure in the fluid pressure control valve, and a target rotation number setting unit configured to calculate a pump-necessary discharge flow rate and a brake fluid amount, and set a target rotation number of the electric motor based on the pump-necessary discharge flow rate.
