Example

[0077] As can be understood from the Figures, the inventive steering and regulating device, the same as the steering and regulating method, can advantageously be used in parallel hybrid drivelines of different construction for motor vehicles. FIG. 1 shows one such driveline 1 with one internal combustion machine VM, one electric machine EM2 and one automatic transmission 7, the last one being designed, for example, as the continuously variable transmission 6HP26 known per se from the Applicant's production program. Therefore, it is not necessary to discuss, in detail, the construction thereof. Moreover, an automated mechanical transmission, a double-clutch transmission or other types of multi-step transmission or continuously variable transmissions can be used instead of a continuously variable automatic transmission.

[0078] In this embodiment, a torque generated by the internal combustion machine VM is relayed via a crankshaft 3 thereof to a torsional vibration damper 4 which, as k...

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.

Description

[0001] This application claims priority from German Application Serial No. 10 2004 043 587.1 filed Sep. 9, 2004. FIELD OF THE INVENTION [0002] The invention relates to a device and a method for steering and regulating components of a hybrid driveline of a motor vehicle. BACKGROUND OF THE INVENTION [0003] To further reduce the fuel consumption and emission of motor vehicles, the motor vehicle industry has sought further to develop hybrid driveline drafts known per se and, therefore, introduce suitable steering and regulating devices. For operating those steering and regulating devices, new steering and regulating methods are, in turn, needed which, due to their complexity, are designed as computer programs and work with the aid of computers, sensors and actuators related thereto. [0004] From GB 2 340 463 A1, a vehicle is known, having a parallel hybrid driveline in which the driveline gears of the vehicle can be optionally driven by an internal combustion machine, an electric motor o...
