A brake booster for a vehicle brake system includes a brake force transmitting element configured to be moveable in an axial direction for transmitting a pedal brake force from a brake pedal to a primary brake cylinder of the vehicle, a booster force transmitting element configured to be moveable in the axial direction for transmitting a booster brake force to the primary brake cylinder, a first rotation sensor kinematically coupled with the brake force transmitting element via a motion converting mechanism, which is configured for converting a translational motion into a rotational motion, for measuring the axial position of the brake force transmitting element, and a second rotation sensor kinematically coupled with the booster force transmitting element for measuring the axial position of the booster force transmitting element; wherein the measurements of the first and second rotation sensors are used for controlling the generation of the booster brake force. According to the disclosure, the motions of the brake force transmitting element and the booster force transmitting element can be measured precisely so that the actions of the brake booster can be controlled with high accuracy. |
