Abstract:
A brake control device applied to a vehicle including a regenerative generator connected to a front wheel has an electric pump, and first and second pressure adjustment valves. The first pressure adjustment valve is provided in a brake fluid reflux path including the electric pump, adjusts the brake fluid to a first hydraulic pressure, and adjusts a rear wheel hydraulic pressure in a rear wheel cylinder to the first hydraulic pressure. The second pressure adjustment valve is provided in the reflux path, reduces the first hydraulic pressure to a second hydraulic pressure, and adjusts front wheel hydraulic pressure in a front wheel cylinder to the second hydraulic pressure. A front wheel flow rate to increase the front wheel hydraulic pressure is calculated using a brake operation member operation amount and a regeneration amount of the regenerative generator. The first pressure adjustment valve is controlled using the front wheel flow rate.
