The invention relates to a vacuum power-boosted braking device which comprises a vacuum pump (1), a brake booster (2) and a power input shaft (3) connected with an engine. The vacuum pump (1) is connected with the brake booster (2). A pressure sensor (4) for detecting the vacuum degree in the brake booster (2) is arranged in the brake booster (2). A clutch is arranged between the power input shaft (3) and a rotor coupling (1.1) of the vacuum pump. The pressure sensor (4) is connected with an automobile engine electronic control unit (5). The clutch is further connected with a drive device used for driving the clutch to be disengaged or engaged. The drive device is connected with the automobile engine electronic control unit (5). The vacuum power-boosted braking device can save energy.
