<P>PROBLEM TO BE SOLVED: To provide a method for operating a drive train. <P>SOLUTION: In the method wherein an actual charge state of an electrical energy storage means is detected by measurement and compared with the established setpoint charge state of the electrical energy storage means to determine one of a plurality of operating modes for the drive train as a function of the actual charge state and the setpoint charge state, the setpoint charge state of the electrical energy storage means is determined as a function of the instantaneous drive state of the motor vehicle. Conclusions are drawn about imminent deceleration, imminent acceleration or imminent cruise control of the motor vehicle as a function of at least one of an instantaneous speed, instantaneous transmission data, and instantaneous hybrid drive data, and the setpoint charge state of the electrical energy storage means is determined as a function of the conclusions. Furthermore, either or both range boundaries of operating modes and range extents defined by the range boundaries are selectively shifted as a function of the setpoint charge state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
