Title: BRAKE SYSTEM FOR A VEHICLE AND METHOD FOR OPERATING A BRAKE SYSTEM OF A VEHICLE
Abstract:
The invention relates to a brake system for a vehicle having a master brake cylinder (10), a brake medium reservoir (12), a first brake circuit with a first wheel brake cylinder (20a) which is hydraulically connected to the brake medium reservoir (12), and a second brake circuit with a second wheel brake cylinder (20b) which, at least in a first operating mode of the brake system, is hydraulically connected to the master brake cylinder (10), wherein the second brake circuit is connected via a first cut-off valve (18) to the first brake circuit and via a second cut-off valve (24) to the master brake cylinder (10), in such a way that the brake system can be switched, by virtue of the first cut-off valve (18) being opened and the second cut-off valve (24) being closed, into a second operating mode in which the second wheel brake cylinder (20b) is hydraulically connected to the brake medium reservoir (12) and the hydraulic connection between the master brake cylinder (10) and the second wheel brake cylinder (20b) is shut off. The invention also relates to a method for operating a brake system of a vehicle.
