Device and method for steering and regulating components of a hybrid driveline of a vehicle

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...

Benefits of technology

[0053] Also considered advantageous in this connection is the other method feature according to which the sporting characteristic can be generated within limits such that therewith can be adjusted a nominal state of charge of the electric energy accumulator such that allows a complete emptying or a complete filling of the energy accumulator in electrically driven, combustion driven and combined driving phases only as long as this energy accumulator is not damaged in the process.

Problems solved by technology

In the steering device, according to WO 02 / 26520 A1, it is disadvantageous that at least two prime movers in the combustion driven, electrically driven and / or one clutch, the same as one transmission in the hybrid driveline, are controlled and regulated only on the basis of values that identify the driver-type the same as the current driving situation.
