The invention relates to a device and a method for controlling an extracorporeal blood treatment device, in particular a haemodialysis device which has a dialyzer (1), divided by a semipermeable membrane (2) into a blood chamber (3) and a dialysis liquid chamber (4), and has a blood pump (6) for conveying blood through the blood chamber at a defined blood flow rate Qb and a dialysis liquid pump (12) for conveying dialysis liquid through the dialysis liquid chamber at a defined dialysis liquid flow rate Qd. The control device according to the invention, for a haemodialysis device, and the control method according to the invention are based on the fact that, for different blood flow rates in each case predefined during the blood treatment, the dialysis liquid flow rates are determined at which a predefined clearance or dialysance is maintained with the predefined blood flow rates and/or that, for different dialysis liquid flow rates in each case predefined during the blood treatment, the blood flow rates are de
