Abstract
A controller of a vacuum brake power booster which amplifies an input force of a brake pedal and outputs the amplified force to a brake device, is characterized by comprising a control signal generating means generating a plurality of kinds of signals for controlling the vacuum brake power booster, and a means for switching or selecting the plurality of signals on the basis of an input different from one of the brake pedal.
