摘要： In a braking control apparatus, a plurality of pumps are driven by a common first motor. A brake supplies operating fluid to pipelines by operating the first motor, and controls opening/closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the right front wheel approach the right front wheel target pressure, and controls opening closing of a fluid pressure regulating valve so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure. In the case where the right front wheel target pressure is zero when the fluid pressure regulating valve is to be opened so as to make the wheel cylinder pressure in the left rear wheel approach the left rear wheel target pressure, the brake turns off the first motor.
