Abstract: A braking control device for a vehicle includes an upper braking unit configured to pressurize a supply pressure by throttling, with a pressure adjustment valve, a circulation flow discharged by a fluid pump driven by an electric motor, and a lower braking unit disposed between the upper braking unit and a wheel cylinder and configured to pressurize the supply pressure to output a wheel pressure to the wheel cylinder. In a case where the lower braking unit pressurizes the wheel pressure, the upper braking unit reduces a rotation number of the electric motor as compared with a case where the lower braking unit does not pressurize the wheel pressure.

Abstract: A vehicle braking control device includes supply and servo chambers sealed by a seal member, a pressure adjustment unit that adjusts front wheel pressure by supplying a first servo pressure to the servo chamber and outputs front wheel supply pressure from the supply chamber to a front wheel cylinder, and adjusts rear wheel pressure by outputting a second servo pressure to a rear wheel cylinder as rear wheel supply pressure, front/rear wheel supply pressure sensors that detect the front/rear wheel supply pressures respectively, and a controller that selects any one of a two-system pressure adjustment for individually adjusting the first and second servo pressures, and a one-system pressure adjustment for adjusting the first and second servo pressures to be the same. The controller individually calculates front/rear wheel target pressures and causes the front/rear wheel supply pressures to coincide with the front/rear wheel target pressures in the two-system pressure adjustment
