Brake system for a vehicle and method for operating a brake system of a vehicle

A method for operating a brake system of a vehicle, the brake system including a master brake cylinder, a brake medium reservoir, a first wheel brake cylinder hydraulically connected to the master brake cylinder, a second wheel brake cylinder hydraulically connected to the master brake cylinder and a pump hydraulically connected to the brake medium reservoir, the first wheel brake cylinder being hydraulically connected to a delivery output of the pump via a first non-return valve and the second wheel brake cylinder being hydraulically connected to the same delivery output of the pump via a second non-return valve, the method comprising:

• providing active buildup/increase of at least one of a first hydraulic braking torque, which is exerted by the first wheel brake cylinder on a first wheel of the vehicle, and a second hydraulic braking torque, which is exerted by the second wheel brake cylinder on a second wheel of the vehicle, by operating the pump so that at least one of a first brake medium volume is pumped from the brake medium reservoir through the first non-return valve into the first wheel brake cylinder and a second brake medium volume is pumped from the brake medium reservoir through the second non-return valve into the second wheel brake cylinder;
• wherein:
• a first continuously adjustable valve is coupled to the brake medium reservoir and hydraulically connected to the first wheel brake cylinder so that a fifth brake medium volume is transferable through the first continuously adjustable valve from the first wheel brake cylinder into the brake medium reservoir when the first continuously adjustable valve is at least partially open;
• and
• a block valve is directly connected on one side to the master brake cylinder via a supply line and directly connected on an opposite side to a junction point where the delivery output of the pump meets the first continuously adjustable valve.

A brake system for a vehicle, comprising:

• a master brake cylinder;
• a brake medium reservoir;
• a first wheel brake cylinder, which is hydraulically connected to the master brake cylinder so that a first brake medium volume is displaceable from the master brake cylinder into the first wheel brake cylinder;
• a second wheel brake cylinder, which is hydraulically connected to the master brake cylinder so that a second brake medium volume is displaceable from the master brake cylinder into the second wheel brake cylinder;
• a pump, which is hydraulically connected to the brake medium reservoir, wherein:
• the first wheel brake cylinder is hydraulically connected to a delivery output of the pump via a first non-return valve so that by using the pump, a third brake medium volume may be pumped from the brake medium reservoir through the first non-return valve into the first wheel-brake cylinder;
• and
• the second wheel brake cylinder is hydraulically connected to the same delivery output of the pump via a second non-return valve so that by using the pump, a fourth brake medium volume is pumpable from the brake medium reservoir through the second non-return valve into the second wheel-brake cylinder;
• and
• a first continuously adjustable valve, which is coupled to the brake medium reservoir and hydraulically connected to the first wheel brake cylinder so that a fifth brake medium volume is transferable through the first continuously adjustable valve from the first wheel brake cylinder into the brake medium reservoir when the first continuously adjustable valve is at least partially open, wherein a downstream side of the first continuously adjustable valve is connected to a wheel brake and to a delivery side of the pump, and an upstream side of the first continuously adjustable valve is connected to a suction side of the pump.
