Abstract
A brake booster pressure control apparatus is provided for controlling the vacuum pressure of a brake booster, the brake booster assisting a braking operation on a brake pedal by using an intake air pressure. The brake booster pressure control apparatus includes a brake-pedal vibration detecting unit that outputs a signal indicative of occurrence of vibrations of the brake pedal. A pressure control unit controls the pressure of the brake booster based on the signal output by the brake-pedal vibration detecting unit.
