| 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.
