摘要： A method for implementing an operating strategy for (plug-in) hybrid vehicles. According to the method, it is possible to cause in a particularly advantageous manner an alleviation of the load of a starting device and thereby achieve emission advantages. A correspondingly configured system arrangement is provided for implementing the method. A non-transitory computer-readable medium programmed to execute the method is also provided, in which control commands implement the method and/or operate the proposed system arrangement.

摘要： A hybrid drive includes an internal combustion engine, an electrical machine, at least one torsional vibration damper, and an electronic control unit. The torsional vibration damper is designed for optimal vibration damping during operation of the internal combustion engine with the full number of cylinders of the internal combustion engine switched-on in internal-combustion-engine mode. The electronic control unit is further designed such that, in purely electric-motor mode where no cylinders are switched on, the electrical machine simulates the cylinder-ignition-dependent torque excitations of the switched-off internal combustion engine substantially identically until the internal combustion engine is switched back on.

摘要： A control unit is provided for a hybrid drive that includes an internal combustion engine and an electric machine. The control unit is configured to cause one or more drag torque reduction measures of the internal combustion engine to be terminated in preparation for firing the internal combustion engine. In addition, the control unit is configured to cause the electric machine to at least partly compensate for an increase in the drag torque of the internal combustion engine caused by the termination of the one or more drag torque reduction measures.

摘要： A controller and a method for a hybrid drive, which includes an internal combustion engine and an electrical machine are provided. The internal combustion engine includes adjustment devices that deactivate the intake and exhaust valve opening actuation. The controller is designed in such a way that, in the case of at least one specified condition (such as regeneration during unfired overrun or in the case of electric travel, in particular in the case of operation with high activation frequency of the internal combustion engine, e.g., in charge sustaining or HEV operation), the intake and exhaust valves are kept at least approximately (preferably completely) closed at least approximately simultaneously while the internal combustion engine is unfired. The internal combustion engine must be connected to the electrical machine. If there is a disconnect clutch, the disconnect clutch is brought into the closed state or remains closed.

摘要： A hybrid drive device has an internal combustion engine, a clutch transmission which has at least one free partial transmission and a partial transmission connected to an electric machine with in each case a clutch, and at least one electric machine. In order to start the internal combustion engine, pulse energy is provided from an inertia of the clutch associated with the free partial transmission and/or a rotation in the free partial transmission.

摘要： A hybrid drive for a vehicle includes an electric machine, an internal combustion engine, and a transmission with a transmission input shaft. The electric machine and the internal combustion engine are coupled to the transmission input shaft such that the electric machine and the internal combustion engine cannot be decoupled.

摘要： A hybrid drive includes a control unit, an internal combustion engine, an electrical machine and a dual clutch transmission having an output shaft. The dual clutch transmission includes a first sub-transmission and a second sub-transmission, each couplable to the output shaft. A drive shaft of the internal combustion engine is couplable to a first input shaft of the first sub-transmission via a first clutch and to a second input shaft of the second sub-transmission via a second clutch. The control unit is configured to permit the second clutch to be closed even when the hybrid drive is being operated purely electrically so that the driveshaft of the internal combustion engine is driven by the electrical machine. A control unit and a method for operation of a hybrid drive are also provided.

摘要： A method for exiting from a recuperation phase in a parallel hybrid vehicle includes, in a first step, the vehicle is in a recuperation phase, started by means of a trigger, with a predefined recuperation driving demand, and, in a second step, the electric machine is brought to an increased rotational speed during the recuperation phase. In a third step, a phase for departing from the recuperation phase is started by means of a trigger, wherein, in this phase, the internal combustion engine is made available for coupling to the electric machine, such that a target rotational speed determined between the internal combustion engine to be connected and the electric machine for the connection to the transmission input is set, and in parallel, by means of an upshift, a highest possible gear ratio for the connection to the drivetrain is set, in order to satisfy a present driving demand. In a fourth step, the departure from the recuperation phase is completed.
