Embodiment Construction

[0026] Figure 2a and 2b A partial schematic view of a brake system that interacts with an embodiment of the control device is shown.

[0027]The control device 50 described below can interact with (almost) every braking system of a vehicle / motor vehicle, said braking system comprising at least one master brake cylinder 52 , connected at said master brake cylinder 52 brake actuating element 53 , at least one sensor 54 and 56 , and at least one brake circuit 58 connected to brake master cylinder 52 , by means of which at least one sensor signal 54 a and 56 a can be detected or can be Estimated driver braking force F applied to the brake actuating element 53 driver The decrease in time (dF driver / dt<0), wherein brake circuit 58 has at least one first wheel brake cylinder 60 , a storage chamber 66 and a high-pressure switching valve 68 . The storage chamber 66 of the brake circuit 58 is connected to the master brake cylinder 52 via the high-pressure switching valve 68 . It i...

Abstract

The invention relates to a controller (50) for a brake system of a vehicle. The controller (50) is designed to detect or estimate whether a driver brake force (Fdriver) exerted onto a brake actuation element (53) connected to a master brake cylinder (52) of the brake system is decreasing over time using at least one sensor signal (54a, 56a) of at least one sensor (54, 56), said signal being provided to the controller (50), and the controller (50) is also designed such that at least temporarily during a known or estimated decrease of the driver brake force (Fdriver) over time, a high-pressure switch valve (68) of a brake circuit (58) that is connected to the master brake cylinder (52) and comprises at least one wheel brake cylinder (60), via which a storage chamber (66) of the brake circuit (58) is connected to the master brake cylinder (52), is actuated into the open state and / or is kept in the open state such that a braking fluid can be transferred from the storage chamber (66) into the master brake cylinder (52) via the high-pressure switch valve (68) in the open state. The invention likewise relates to a method for emptying a storage chamber (66) of a brake system of a vehicle.

Description

technical field [0001] The invention relates to a control device for a braking system of a vehicle and to a braking system for a vehicle. Likewise, the invention relates to a method for emptying a storage chamber of a brake system of a vehicle. Furthermore, the invention relates to a method for limiting brake pressure in at least one wheel cylinder of a brake system of a vehicle and a method for braking a vehicle by means of generator operation of an electric motor method. Background technique [0002] Figures 1a to 1d show a partial schematic view of a conventional braking system, which is the prior art of the present application as an internal state of the art, and a coordinate system for explaining the way in which this conventional braking system works known. [0003] The conventional brake system depicted schematically in FIGS. 1 a and 1 b has a master brake cylinder 10 with a brake pedal 12 connected thereto. For greater clarity, only the brake circuit 14 of the br...
