Method for controlling electronically slip-adjustable power-assisted brake system with redundant brake pressure generation

The invention relates to a method for controlling an electronically slip-adjustable power-assisted brake system (10) with redundant brake pressure generation. Depending on the operation, a displacement of the pressure-volume characteristic curve towards a higher pressure may occur in such a booster brake system (10). And if the actual change process of the pressure-volume-characteristic curve deviates from the target change process to reach the degree that the target change process cannot be tolerated any more, correction is needed. For this purpose, a pressure medium volume must be discharged from the brake circuit (18a, 18b) into a reservoir (32) of the booster brake system (10). The invention relates to a method by means of which pressure can be discharged into the reservoir (32) in a controlled manner. The method can be carried out during the braking process without any unwanted noise or unexpected deceleration changes. The method can be implemented in terms of control technology and thereby in a particul
