1. A brake system for a vehicle, comprising:
a first hydraulic circuit including a first wheel brake,
a second hydraulic circuit including a second wheel brake,
a first hydraulic pressure supplier including an actuator configured to pressurize the first hydraulic circuit in a normal operating mode,
a second hydraulic pressure supplier including an actuator configured to pressurize the second hydraulic circuit in the normal operating mode,
a cut-off valve hydraulically connecting the first and second hydraulic circuits,
a first controller configured to control the cut-off valve and activate the first hydraulic pressure supplier and the second hydraulic pressure supplier depending on a brake request, and
a second controller configured to control the cut-off valve and activate the first hydraulic pressure supplier and the second hydraulic pressure supplier depending on a brake request,
wherein the first controller and/or second controller are configured to keep the cut-off valve closed in the normal operation mode and to open the cut-off valve in an emergency mode or in a pressure balancing mode,
wherein the first hydraulic pressure supplier is hydraulically connected to both the first hydraulic circuit and the second hydraulic circuit for pressurizing said hydraulic circuits in the emergency mode or
wherein the second hydraulic pressure supplier is hydraulically connected to both the first hydraulic circuit and the second hydraulic circuit for pressurizing said hydraulic circuits in the emergency mode,
wherein:
the first controller is directly electrically connected to the first hydraulic pressure supplier and the second hydraulic pressure supplier to directly control the first hydraulic pressure supplier and the second hydraulic pressure supplier, and
the second controller is directly electrically connected to the first hydraulic pressure supplier and the second hydraulic pressure supplier to directly control the first hydraulic pressure supplier and the second hydraulic pressure supplier.
