Braking pressure-sensor and/or control device for use in e.g. hydraulic brake system of motor car for adjusting braking pressure, has evaluating device determining actual braking pressure variable and/or target-volume change variable

摘要

The device has an evaluating device (28) determining an actual braking pressure variable relative to a braking pressure present in a wheel brake cylinder of a brake system, and/or a target-volume change variable (30) e.g. pumping capacity, relative to a braking fluid volume by considering an actual-pre pressure variable (14) and an actual braking fluid volume variable (20) or evaluating variables with weight factors (32, 34). The braking fluid volume is transferred between a brake circuit and storage volumes for adjusting a preset target-brake pressure within the brake system. An independent claim is also included for a method for operating a brake system.
