Abstract:
1. A brake control device comprising: a flow control valve, placed between a brake fluid pressure generation unit on an upstream side that generates brake fluid pressure and a braking force generation unit on a downstream side that generates braking force in accordance with the brake fluid pressure to a wheel, that regulates the brake fluid pressure to the braking force generation unit by controlling a flow rate of brake fluid; a differential pressure obtaining unit that obtains, from brake fluid pressure on upstream and downstream sides of the flow control valve, information on a difference of the brake fluid pressure; a hydrodynamic force obtaining unit that obtains information on hydrodynamic force that is a sum of forces in valve closing and opening directions working on a valve element by a flow of brake fluid passing through the flow control valve; and a brake fluid pressure control unit that controls the flow control valve by use of the information on the differential pressure and the information on the hydrodynamic force.
