  • Method for operating a drive train of a vehicle
    Publication number: 20070167284
    Abstract: A method for operating a drive train of a vehicle with a hydrodynamic torque converter, one transmission device and one prime mover during a gearshift starting from an actual ratio to a target ratio. A nominal standard of the control pressure of the shifting element to be disengaged is adjusted according to a nominal standard of the control pressure of the shifting element to be engaged. The rotational speed of a turbine of the torque converter is passed during the gearshift, starting from a synchronous rotational speed of the turbine of the actual ratio, in direction of a synchronous rotational speed of the turbine of the target ratio, the nominal standard of the control pressure of the shifting element to be disengaged.
