Control device and method for raising at least one braking pressure of at least one wheel brake cylinder of a vehicle brake system

摘要

The present invention relates to a control device (10) for a vehicle brake system having an electronic device (12), which operates a motor-driven piston-cylinder device (14) in a pressure- Cylinder motor 30 and one or more first isolation valves 26 connecting the brake master cylinder 30 and one or more wheel brake cylinders 28 to its closed state and to control the motorized piston- Is designed to control or maintain the at least one second isolation valve (32) connecting the wheel brake cylinder (28) in its open state; The sniffing mode is designed to operate the motor-driven piston-cylinder device 14 and at the same time control at least one second isolation valve 32 to its closed state; In this case, the electronic device 12 is further designed to control the at least one first isolation valve 26 at least temporarily in its open state during the sniffering mode. The present invention also relates to a method for raising at least one braking pressure of one or more wheel brake cylinders (28) of a vehicle brake system.
