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: This braking control device comprises a first unit that outputs supply pressure in accordance with the amount of operation of a braking operation member, a second unit that is provided between the first unit and a wheel cylinder and that increases the supply pressure and outputs a wheel pressure to the wheel cylinder, a communication bus that transfers signals between the first unit and the second unit, an operation amount sensor that detects the amount of operation, and a supply pressure sensor that detects the supply pressure. In the braking control device, the first unit controls the supply pressure so as to bring the supply pressure close to a target pressure calculated on the basis of the amount of operation. When the first unit is abnormal, the second unit increases the wheel pressure on the basis of the deviation between the target pressure and the supply pressure.
