Abstract: A braking control device for vehicles that comprises: a first unit that outputs a supply pressure in accordance with the amount a braking operation member is operated; a second unit that is provided between the first unit and a wheel cylinder, regulates the supply pressure, and outputs a wheel pressure to the wheel cylinder; a communications bus that transfers signals between the first unit and the second unit; an operation amount sensor that is connected to the first unit and detects the operation amount; and a supply pressure sensor that is connected to the second unit and detects the supply pressure. The first unit calculates a target pressure on the basis of the operation amount, obtains the supply pressure from the second unit via the communications bus, and performs feedback control such that the supply pressure matches the target 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.

Abstract: This braking control device comprises a first unit for outputting a supply pressure in accordance with operation displacement of a braking operation member, a second unit between the first unit and a wheel cylinder to increase the supply pressure and output a wheel pressure to the wheel cylinder, a displacement sensor for detecting the operation displacement, and a supply pressure sensor for detecting the supply pressure. The first unit selects either a first mode in which the operation displacement and the supply pressure are independent or a second mode in which the operation displacement and the supply pressure are linked. When the displacement sensor is normal, the first unit selects the first mode and increases the supply pressure based on the operation displacement. When the displacement sensor is not normal, the first unit selects the second mode, and the second unit increases the wheel pressure based on the supply pressure.

Abstract: This braking control device comprises: a first unit that outputs a 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 adjusts the supply pressure to output a wheel pressure to the wheel cylinder; a communication bus for communicating signals between the first unit and the second unit; an operation amount sensor that detects the operation amount; and a supply pressure sensor that detects the supply pressure. In the braking control device, when there is an abnormality in signal communication, the second unit calculates a target pressure on the basis of the operation amount and adjusts the wheel pressure on the basis of the difference between the target pressure and the supply pressure.
