    摘要： In a brake control apparatus, a fluid passage section is hydraulically connected between a hydraulic pressure source and a wheel cylinder. A first pressure sensor measures a first quantity correlated to a hydraulic pressure outputted by the hydraulic pressure source. A second pressure sensor measures a second quantity correlated to an internal pressure of the wheel cylinder. A controller controls a braking force of a wheel by the wheel cylinder. The controller is configured to: allow the first pressure sensor to obtain a value of the first quantity, and allow the second pressure sensor to obtain a value of the second quantity, while allowing a selector to regulate fluid communication between the hydraulic pressure source and the wheel cylinder; and calibrate the first and second pressure sensors with respect to each other in accordance with the obtained values of the first and second quantities.

    摘要： A brake control apparatus has wheel cylinders, hydraulic pressure supply sources pressurizing an inside of the wheel cylinder, control valves performing a pressure-raising/reducing control of the inside of the wheel cylinder, and at least two actuator units grouped according to a diagonal wheel cylinder system or a fore-and-aft wheel cylinder system, one of which has a main control section and the other of which has a sub control section. Both the control sections control the plurality of hydraulic pressure supply sources and the control valves based on a vehicle status amount input to both the control sections via communication lines. When the actuator unit in which the main control section is included becomes abnormal, the sub control section drives the hydraulic pressure supply source and the control valves belonging to the actuator unit of the sub control section and controls the internal pressures of the wheel cylinders.

    摘要： A brake control apparatus includes an actuator configured to generate a braking force of road wheel; a first control unit configured to calculate a target braking controlled variable in accordance with an amount of brake manipulation of a driver; and a second control unit including a backup calculation section configured to calculate a backup target braking controlled variable, by receiving the amount of brake manipulation separately from the first control unit. The second control unit selects one of the target braking controlled variable and the backup target braking controlled variable in accordance with operating conditions of the first control unit and the second control unit. The second control unit outputs a drive signal to the actuator so as to bring the braking force of road wheel closer to the selected one of the target braking controlled variable and the backup target braking controlled variable.
