20090020354 | Drivetrain, Hybrid Vehicle, and Operating Methods Therefor - A drivetrain for a hybrid vehicle includes an internal combustion engine, a transmission and electric machine, and an electrical energy store. The electric machine is usable as a generator for charging the electrical energy store and/or as a motor while discharging the electrical energy store. The electrical energy store is implemented as a flywheel mass accumulator having an assigned second electric machine. The flywheel mass accumulator is able to be mechanically coupled to the internal combustion engine via a separate clutch, and thus also is mechanically chargeable and dischargeable. | 01-22-2009 |
20110094809 | MIXED HYBRID - A hybrid drive train for a vehicle has an internal combustion engine, first and second electric machines and a transmission that are mechanically connected to one another to drive at least one axle of the vehicle. The internal combustion engine ( | 04-28-2011 |
20110112710 | METHOD FOR ESTIMATING THE RANGE OF A MOTOR VEHICLE - A method is provided for estimating the range of a motor vehicle based on a quantity of energy carried in the motor vehicle. The method enables a driver to limit a maximum permissible velocity and/or a maximum permissible acceleration and/or a maximum performance level for a comfort system. The method also detects the route profiles surrounding the motor vehicle, in particular an altitude profile and/or a road category. A computer device calculates and displays a still possible range at least on the basis of the limitation which has been carried out, the detected route profiles and the still available quantity of energy. | 05-12-2011 |

20110251763 | METHOD FOR IDENTIFYING A DRIVING RESISTANCE OF A MOTOR VEHICLE - A method for identifying a driving resistance of a motor vehicle includes the steps of recording values of control and/or state variables of the vehicle during a driving state of the vehicle when a control route is covered, adapting parameters of a vehicle model and/or a model of the area surrounding the vehicle on the basis of the values of the recorded control and state variables, identifying the driving resistance on the basis of the adapted vehicle model and/or the surrounding area model, wherein the parameters of the vehicle model and/or the surrounding area model are adapted on the basis of a distinction between driving states, wherein these driving states include a driving state of a closed drive train with a positive driver demand torque, a driving state of a closed drive train without a positive driver demand torque, and/or and a driving state with an open drive train. | 10-13-2011 |
20110282531 | METHOD AND DEVICE FOR CONTROLLING A BATTERY PULSE HEATING MODE OF A TRACTION BATTERY OF A HYBRID VEHICLE - A method and a device are provided for controlling a battery pulse heating mode of a traction battery of a hybrid vehicle. The method includes detecting a traction battery temperature (T) upon start-up of the hybrid vehicle. The method then includes determining a dependency of fuel consumption (V) during a battery pulse heating mode on the distance (W) travelled for at least one predefined road type at the detected traction battery temperature (T). The method continues by displaying the determined dependency on a display device ( | 11-17-2011 |

20140299395 | METHOD FOR OPERATING A HYBRID VEHICLE - A method is provided for operating a hybrid vehicle. The hybrid vehicle has an internal combustion engine and a first electric machine, to which a common input shaft of a transmission is assigned, for driving a first axle of the hybrid vehicle. The hybrid vehicle also has a second electric machine for driving a second axle of the hybrid vehicle, and a traction battery is provided for the two electric machines. The electric machines have a total power greater than the power of the internal combustion engine. The method includes operating the first electric machine in a generator mode for charging the traction battery when the hybrid vehicle is driven exclusively by internal combustion engine. The method ensures, with a high level of electrification, a long electromotive travelling range of the vehicle. | 10-09-2014 |
