Parameter estimation for a vehicle brake system equipped with a motorized piston-cylinder device. The estimation includes controlling an electric motor of the motorized piston-cylinder device so that at least one piston, displaceable by the operated electric motor, of the motorized piston-cylinder device is displaced from its initial position; ascertaining/estimating a brake fluid volume displaced by the at least one displaceable piston of the motorized piston-cylinder device between the motorized piston-cylinder device and at least a part of the brake system adjoining the motorized piston-cylinder device; ascertaining/estimating a change in pressure occurring due to the displaced brake fluid volume at least in the part of the brake system adjoining the motorized piston-cylinder device; and determining an elasticity of the brake system and/or a rigidity of the brake system at least taking into account the ascertained or estimated displaced brake fluid volume and the ascertained or estimated change in pressure.
