Abstract
Method of and apparatus for control of the heating capacity of a hydrodynamic brake which is associated with a liquid-cooled internal combustion engine, in the cooling medium circuit of which heat exchangers, a cooling medium circulating pump and the hydrodynamic brake acting as a heater are arranged. A regulation of the state of charge of the working chamber of the hydrodynamic brake occurs by a pressure regulator valve. In the case of a method and apparatus for controlling the heating capacity taking an available drive power into consideration, the pressure regulator valve which influences the heating capacity is controllable as a function of the load of the internal combustion engine.
