  • Patent number: 8297600
    Abstract: A plastic spring having a corrugated tubular body with connection surfaces at its ends for transmitting force between two structural component parts which are movable relative to one another. A connection surface of the plastic spring is constructed as a tubular body which engages in a cup element of one of the supporting structural component parts. The cup element can be filled with a displacement mass, and the tubular body accordingly carries out a displacing movement within the cup element for axially adjusting the preloading of the plastic spring.

  • Publication number: 20120138405
    Abstract: A method for changing a drive unit's mechanical coupling to a motor vehicle power train, which has at least two drive units, in which at least one first drive unit of the two drive units is coupled via various mechanical couplings, including mechanical transmission ratios, during the travel of the motor vehicle, a power or torque influence of the two drive units occurring if there is a change of the mechanical coupling. To ensure a change of the mechanical coupling without the vehicle occupants perceiving it, the change of the mechanical coupling of the first drive unit of the two drive units occurs in at least two operating modes, a first operating mode causing a slower operating point change with respect to time of the two drive units, while a more rapid operating point change as to time of the two drive units is provided in a second operating mode.

  • Patent number: 8186464
    Abstract: In a method for operating a parallel hybrid drive of a vehicle, in particular of a motor vehicle, having an electric machine and an internal combustion engine, the internal combustion engine is started in the driving state of the vehicle with the aid of the electric machine by engaging a disconnecting clutch. It is provided that at least one performance quantity of the parallel hybrid drive is detected and compared with an appropriate model performance quantity of a model of the parallel hybrid drive, the model not including the internal combustion engine, and that a deviation resulting from the comparison is compensated for, at least partially, by the electric machine.

  • Patent number: 8167065
    Abstract: A method and device for dynamic torque coordination of power units of a hybrid drive of a vehicle, in particular a motor vehicle. The method has a plurality of successive coordination stages, each coordination stage being assigned an operating range for at least one of the power units, and each coordination stage making at least one demand on a first power unit and/or a second power unit as a function of an overall setpoint torque requested from the hybrid drive, a subsequent coordination state having an enlarged operating range compared to a preceding coordination stage, and the subsequent coordination stage is used if the demand was unable to be satisfied within the operating range of the assigned coordination stage.

  • Patent number: 8131454
    Abstract: A method is described for starting an internal combustion engine having an E-machine coupled to it in a motor vehicle, after the input of a certain torque command at a drive control of the internal combustion engine, the internal combustion engine being accelerated for the start by the E-machine, and the internal combustion engine being set by the drive control, via actuators, to specified characteristics values for the start. To reduce exhaust gas emissions at the start of the internal combustion engine, the internal combustion engine is accelerated by the E-machine, without the injection of fuel, until the engine torque that is able to be implemented by the internal combustion engine, essentially corresponds to the torque command, and the injection of fuel into the internal combustion engine is only then released.

  • Publication number: 20120035820
    Abstract: A method is described for operating a vehicle, in particular a hybrid vehicle, in which each of the two axles of the vehicle, which are not mechanically coupled, is driven by at least one drive unit, thus transmitting a torque to the wheels of the respective axle. To make optimal use of the different coefficients of friction of the wheels which occur with different roadway conditions, the rotational speeds of the wheels of both drive axles are ascertained and averaged, a difference being formed from the averaged rotational speeds of the two axles, respectively, and the torque on at least one axle being influenced based on this difference so that differences in the averaged rotational speeds of the wheels are counteracted. Instead of the rotational speed difference, the deviation of this rotational speed difference from a setpoint rotational speed difference may be used, for example, within the scope of ESP.

  • Publication number: 20120004832
    Abstract: A method for operating an internal combustion engine includes: providing a desired power specification for triggering the drive unit; providing a specification of operating point-dependent power ranges for the supplied desired power specification, in which steady-state operation of the drive unit is permissible, a power range that is not permissible in the steady state being defined between the operating point-dependent power ranges; when a change in the desired power specification for the drive unit in a transitional operating mode necessitates traversing the power range that is not permissible in the steady state, triggering the drive unit on the basis of a specification of a guided desired power, the guided desired power specification being determined by guiding the desired power specification.

  • Publication number: 20110288702
    Abstract: In a method for operating a hybrid vehicle, an idle first drive unit is started during the driving of the hybrid vehicle by transferring part of a torque from an operating second drive unit to the first drive unit. To minimize effects on the movement characteristics of the hybrid vehicle during starting and/or stopping of the first drive unit, a control unit is provided for influencing the torque of the operating second drive unit by at least one of the variables derived from the longitudinal movement of the hybrid vehicle.

  • Patent number: 8037955
    Abstract: A method for operating a hybrid drive having at least one first and one second drive-connected drive machine, in which an actual torque of at least one of the drive machines is influenced by a reference-forming element in that, from a combined setpoint torque, a first setpoint torque is formed for a slow influencing path and a second setpoint torque is formed for a fast influencing path for the first drive machine and a setpoint torque is generated for a fast influencing path of the second drive machine. A provision is made for the lead setpoint torque for influencing the slow influencing path of the first drive machine to be obtained from the unfiltered combined setpoint torque before the combined setpoint torque is processed in the reference-forming element.
