• a hydraulic brake system;
• and
• a brake assistance device operably connected to the hydraulic brake system, the brake assistance device including:
• a sensor including a first piston;
• a compensation volume including a second piston and a pretensioning element;
• a 2/2-way valve;
• a brake piston;
• and
• an actuator,
• wherein the pretensioning element is configured to exert a pressure onto the second piston and thus onto a hydraulic fluid of the hydraulic brake system, and
• wherein the actuator is configured to move the second piston selectively in a first direction or in a second direction oriented opposite the first direction.
