Abstract
A method and a device for steering and regulating components of a hybrid driveline (1, 2). For the mode of operation sparing in fuel and poor in emission of a motor vehicle having one such driveline, it is provided that the input torque desired by the driver be distributed among the drive torques of one internal combustion machine (VM) and of at least one electric machine (EM1, EM2) and such a driving mode be selected so that the state of charge of an electric energy accumulator (28) is optimally adapted to the actual rather dynamic or rather economic mode of operation of the driver.

34. A device for steering and regulating components of a hybrid driveline (1, 2) of a motor vehicle with at least two prime movers (VM, EM1, EM2), at least one clutch (K1, K2) and one transmission (7) comprising:
-
one device (22) for determining a nominal input torque (fahr_soll_m) from one variable signalizing one of an actual torque desired by a driver or from a nominal torque standard of an automatic nominal-torque defining device;
one device (23) for determining a sporting characteristic value (kSport);
one device for establishing a nominal state of charge of an electric energy accumulator (28) of the vehicle depending on the determined nominal input torque (fahr_soll_m) and the sporting characteristic value (kSport);
one device (24) for establishing an input distribution between the at least two prime movers (VM, EM1, EM2) depending on an established nominal state of charge so that a required input torque can be implemented and the nominal state of charge of the energy accumulator be kept and to determine for a preset nominal input torque and a best suited nominal driveline configuration for a preset sporting characteristic value; and
one device (27) for generating and relaying steering and regulating signals for at least both the at least two prime movers (VM, EM1, EM2), the at least one clutch (K1, K2), and the transmission (7). - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

- 49. A method for steering and regulating components of a hybrid driveline of a motor vehicle having at least two prime movers (VM, EM1, EM2), at least one clutch (K1, K2) and one transmission (7), comprising the steps of the input torque desired by a driver is divided up into nominal input torques for an internal combustion machine (VM) and at least one electric machine (EM1, EM2), the same as a driving mode being selected such that a state of charge of an electric energy accumulator (28) is adapted optimally to an actual rather dynamic or rather economic driving mode of the driver.
