Brake system

Brake system (1) for a vehicle, comprising

• a first hydraulic circuit (10) including a first wheel brake (11),
• a second hydraulic circuit (20) including a second wheel brake (21),
• a first hydraulic pressure supplier (12) including an actuator for pressurizing the first hydraulic circuit (10) in a normal operating mode,
• a second hydraulic pressure supplier (22) including an actuator for pressurizing the second hydraulic circuit (20) in the normal operating mode,
• a cut-off valve (30) hydraulically connecting the first and second hydraulic circuits (10, 20),
• a first control unit (14) for controlling the cut-off valve (30) and activating the first hydraulic pressure supplier (12) and the second hydraulic pressure supplier (22) depending on a brake request, and
• a second control unit (24) for controlling the cut-off valve (30) and activating the first hydraulic pressure supplier (12) and the second hydraulic pressure supplier (22) depending on a brake request,
• wherein the first control unit (14) and/or second control unit (24) are configured for keeping the cut-off valve (30) closed in the normal operation mode and to open the cut-off valve (30) in an emergency mode or in a pressure balancing mode,
• wherein the first hydraulic pressure supplier (12) is hydraulically connected to both the first hydraulic circuit (10) and the second hydraulic circuit (20) for pressurizing said hydraulic circuits (10, 20) in the emergency mode or
• wherein the second hydraulic pressure supplier (22) is hydraulically connected to both the first hydraulic circuit (10) and the second hydraulic circuit (20) for pressurizing said hydraulic circuits (10, 20) in the emergency mode.
