  • Publication number: 20100274423
    Abstract: A regulating method for hybrid vehicles having an electric motor and an internal combustion engine, for rotational speed regulation of the electric motor, including detecting the driving speed of the vehicle, detecting a desired torque, and comparing the driving speed with a driving speed minimum value, in which, when a desired torque below a torque minimum value is detected and the comparison yields the result that the driving speed is not above the driving speed minimum value, the electric motor is regulated to a setpoint idle speed which is below the minimum idle speed of the internal combustion engine.

  • Publication number: 20100173744
    Abstract: A method and an apparatus are provided for operating a drive unit having at least one combustion engine and at least one electrical machine mechanically coupled to the at least one combustion engine. The method and apparatus enable improved boost operation. In an embodiment, a target value for an output variable of the drive unit is implemented by the at least one combustion engine and the at least one electrical machine. The contribution of the at least one electrical machine to the implementation of the target value for the output variable is made available at most for a predefined time.

  • Publication number: 20100151990
    Abstract: A method and a device for compensating a transmitted torque of a clutch between a regulated drive motor, in particular an electric motor, and an internal combustion engine of a hybrid drive when transitioning from an exclusive operation using the drive motor to a hybrid operation, a total torque from the drive motor and the internal combustion engine being jointly provided in hybrid operation, the rotational speed of the drive motor being controlled or regulated with the aid of a manipulated variable; the internal combustion engine being entrained at a controllable transmitted torque by coupling to the drive motor via a proportional clutch for performing the transition. The rotational speed of the drive motor is controlled or regulated as a function of a setpoint transmitted torque using which the drive motor is to be coupled to the internal combustion engine.

  • Publication number: 20100042276
    Abstract: A method for controlling a vehicle drive unit, which comprises at least two individual drives, at least one of which is able to provide a negative torque. A vehicle control unit is provided, within which a continuous torque comparison is performed within a monitoring level. A permissible torque is ascertained therein. Using a torque range checker it is established whether ascertained setpoint torques lie within torque ranges of the at least two individual drives.

  • Publication number: 20090308673
    Abstract: A method is described for starting an internal combustion engine of a hybrid drive having at least one electric drive. This drive can be coupled to the internal combustion engine via a first clutch for the pulse start of the engine. A speed change of the at least one electric drive occurring during the pulse start of the internal combustion engine is compensated for by continuously occurring changes of the transmission ratio in a vehicle transmission.

  • Publication number: 20090305842
    Abstract: In a method for controlling a vehicle drive unit having at least two individual drives and a vehicle control unit, a continuous torque comparison between a permissible torque MZul and a further torque is performed by the control unit. The permissible torque MZul is continuously compared to setpoint torques Msetpoint,V and Msetpoint,E for the least two individual drives.

  • Publication number: 20090132108
    Abstract: A method for controlling a motor vehicle drive, in particular a hybrid drive, is provided, the motor vehicle drive having at least two individual motors. In a first method step, at least one total setpoint torque is calculated. In a second step, the at least one total setpoint torque is split into at least two individual setpoint torques of the at least two individual motors. Subsequently, in a first individual torque comparison step, the sum of the at least two individual setpoint torques is compared with the total setpoint torque. In the event of a difference by more than a predefined tolerance value, a limitation step is initiated. In this limitation step, the at least two individual setpoint torques are each multiplied by a limiting factor to generate at least two limited individual setpoint torques.

  • Publication number: 20090124453
    Abstract: A method for operating a hybrid drive system, in particular of a motor vehicle, having at least one electric machine and one internal combustion engine, a disconnecting clutch being provided between the electric machine and the internal combustion engine and a torque converter having a turbine wheel being provided between the electric machine and a hybrid drive output, the disconnecting clutch being engaged for starting the internal combustion engine. It is provided that, as a function of the rotational speed of the turbine wheel of the torque converter, a rotational speed is predefined for the electric machine such that no sudden torque change occurs at the hybrid drive output when the internal combustion engine is started.

  • Publication number: 20080274856
    Abstract: A method for compensating a transmitted torque of a clutch between a regulated drive motor, in particular an electromotor, and a combustion engine in the transition to an operation using only the drive motor, to hybrid operation in which an overall torque is supplied jointly by the drive motor and the combustion engine, and the engine speed of the drive motor is controlled with the aid of a manipulated variable; to implement the transition, the combustion engine is dragged by coupling it with the drive motor with the aid of a proportional clutch having a controllable transmitted torque, and the control of the engine speed of the drive motor is implemented as a function of the transmitted torque using which the drive motor is coupled with the combustion engine.

  • Publication number: 20080249696
    Abstract: A method and a device for operating a drive unit which enable better torque coordination for a speed controller. A load-reversal damping component is provided, which filters a first setpoint value for an output variable of the drive unit to damp a load reversal. A speed controller is provided, which specifies a second setpoint value for the output variable of the drive unit in order to adjust an actual value for an engine speed of the drive unit to a setpoint value for the engine speed. A first component of the second setpoint value for the output variable specified by the speed controller is taken into account in the formation of the first setpoint value.
