<p>A vacuum brake booster which applies a supporting force to a main cylinder, as well as a method for its operation are described. The supporting force of the vacuum brake booster is able to be set via an adjusting device as well as via a main control valve. Consequently, the brake booster is operable in two operating modes, in a first operating mode, the supporting force being set by the adjusting device, and in a second operating mode, by the main control valve. Among other things, the brake booster is able to be used in brake systems in which the braking effect of a hydraulic and an additional brake system are combined, the braking effect of the hydraulic brake system having to be adapted to that of the additional brake system, for instance, in the case of regenerative brake systems of an electric or an hybrid vehicle.</p> |
