Abstract
A method for filing a retarder with an operating fluid through a valve connected to a fluid reservoir having air pressure P and conveying an operating fluid with an actuating pressure P in the retarder. The method comprises: after starting the retarder during a first time interval T , an overshoot actuating pressure P (U) lying above nominal pressure P NENN for the nominal braking torque to be regulated is adjusted. In a second time interval T , overshoot actuating pressure P (U) is reduced to a nominal pressure P NENN. The overshoot actuating pressure P (U) and timer intervals T and T are determined or regulated depending on at least one of the following parameters: reservoir air pressure P , retarder oil temperature, retarder or vehicle speed, vehicle acceleration, vehicle transversal acceleration, ABS signal, axle load, brake-pause interval, operating fluid level, outside temperature, speed of the actuating element, acceleration with respect to nominal value settings (speed variation without nominal value dynamics).
