Abstract
The invention relates to an electronically controllable braking system for motor vehicles with a brake pressure generator unit (2) which can be actuated by a brake pedal (1), which supplies hydraulic fluid via a hydraulic fluid path (3) to at least one wheel brake (4) of the motor vehicle, a first electromagnetic valve arrangement (5a, 5b) which is arranged in the hydraulic fluid path between the brake pressure generator unit (2) and the wheel brake (4) for controlling the pressure build-up, pressure relief and pressure holding phases in the wheel brake, a motor-powered controllable hydraulic pressure source (7) which, in addition to or in lieu of the brake pressure generator unit (2), supplies hydraulic fluid to the wheel brake (4), and a motor-powered controllable auxiliary energy source (15, 30) which boosts an actuation of the brake pressure generator unit (2) by the brake pedal (1) or which effects an actuation of the brake pressure generator unit (2) in lieu of the brake pedal (1), with the controllable auxiliary energy source (15, 30) and the controllable hydraulic pressure source (7) being driven by the same motor (8) and being continuously connected with same via a gear me…
