Brake system and method for operating a brake system

A brake system for a vehicle, comprising:

• a main brake cylinder, which is configured to detect an actuation of a brake input element and to provide a pressure signal corresponding to the actuation of the brake input element;
• and
• a first brake circuit, including:
• at least one first wheel brake cylinder, which is situated on a first wheel and which is coupled to the main brake cylinder so that the pressure signal may be transmitted from the main brake cylinder to the first wheel brake cylinder, and which is configured to exert a force on the first wheel corresponding to the pressure signal;
• a first switchover valve, which is situated between the main brake cylinder and the first wheel brake cylinder and which as an isolating valve is configured to prevent the pressure signal from being transmitted to the first wheel brake cylinder when a provided closing signal is received;
• a first pump;
• a storage chamber, the storage chamber in a neutral state having a storage volume on a side facing the first pump;
• and,
• a first wheel outlet valve which is associated with the first wheel and which is configured to control a flow of braking medium between the first wheel brake cylinder and the storage chamber.

A method for controlling a brake system for a vehicle, the method comprising:

• receiving a provided closing signal and closing a first switchover valve to prevent a pressure signal from being transmitted from a main brake cylinder to a first wheel brake cylinder;
• receiving a provided control signal for a brake pressure to be applied to a first wheel;
• and
• controlling a flow of brake fluid between the first wheel brake cylinder and a storage chamber for adjusting the brake pressure at the first wheel;
• wherein a main brake cylinder is configured to detect an actuation of a brake input element and to provide a pressure signal corresponding to the actuation of the brake input element, and having a first brake circuit having at least one first wheel brake cylinder which is situated on the first wheel and which is coupled to the main brake cylinder so that the pressure signal may be transmitted from the main brake cylinder to the first wheel brake cylinder, and which is configured to exert a force on the first wheel corresponding to the pressure signal, having a first switchover valve which is situated between the main brake cylinder and the first wheel brake cylinder and which is configured as an isolating valve, having a first pump and the storage chamber, the storage chamber in a neutral state having a storage volume on a side facing the first pump, and having a first wheel outlet valve which is associated with the first wheel.

A brake system for a vehicle, comprising:

• a main brake cylinder configured to detect an operation of a brake input element and to provide a pressure signal that corresponds to the operation of the brake input element;
• and
• a first brake circuit, including:
• at least one first wheel brake cylinder situated on a first wheel, which is coupled to the main brake cylinder so that the pressure signal is able to be transmitted on from the main brake cylinder to the first wheel brake cylinder, and which is configured to exert a force corresponding to the pressure signal on the first wheel;
• a first switchover valve situated between the main brake cylinder and the first transmitting on of the pressure signal to the first wheel brake cylinder upon a reception of a provided closing signal;
• a storage chamber;
• a first pump, wherein in a neutral state the storage chamber has a storage volume on a side facing the first pump;
• and
• a wheel outlet valve associated with the first wheel, which is configured to control a braking medium flow between the first wheel brake cylinder and the storage chamber;
• and
• a second brake circuit, including a second wheel brake cylinder situated on a second wheel, which is coupled to the main brake cylinder, wherein a braking torque difference between a total braking torque intended by the driver and the braking torques exerted using a friction brake on the wheels of the second brake circuit and exerted on the wheels of the first braking circuit using a recuperative brake being calculated using an evaluating device and the braking torque difference is set at the wheels of the first braking circuit using the first pump.
