Procedure for control of brake device in drive train of vehicle has with activated control of hydrodynamic retarder according to basic concept, deactivation of control undertaken on generation of constant braking torque

摘要

A procedure for the control of a brake device in a drive train of a vehicle is described. With activated control of the hydrodynamic retarder according to the first basic concept and the existence of a signal pointing to a possible gear change taking place and/or characterising at least indirectly a shifting process, a deactivation of the control is undertaken on generation of a constant braking torque and the control (open or closed loop) is commissioned on generation of a certain braking torque for the attainment of a constant travel speed.
