Abstract
An electronic control unit for a brake control apparatus has a pressure-command-signal memorizing portion, which outputs a pressure command signal to a brake force control unit, when a braking operation is not carried out by a vehicle driver, in order to gradually increase brake fluid pressure. The memorizing portion memorizes the pressure command signal as a gap-zero pressure signal sent to the brake force control unit when vehicle deceleration exceeds a predetermined value. A pre-charge control portion outputs the gap-zero pressure signal to carry out a pre-charge control, when the braking operation is not carried out, so that a gap between a friction element and a non-friction element is reduced to a desired amount before an actual braking operation by the vehicle driver.
