| 20090005925 | Method For Controlling A Drivetrain For A Hybrid Vehicle - A method for controlling a drivetrain for a hybrid vehicle is provided. The drivetrain has at least one internal combustion engine, a torque converter and an operational link to at least one drivable axle, an electrical energy store, and an electrical machine, which is usable as a generator for charging the electrical energy store during a recuperation operation. The electrical machine is provided on the pump wheel and the operational link being provided on the turbine wheel of the torque converter. A torque is introduced from the drivable axle via the operational link and through the turbine wheel into the liquid of the torque converter in recuperation operation in order to be dissipated as heat. | 01-01-2009 |
| 20090015023 | Method for Controlling a Drivetrain and Drivetrain - A method for controlling a drivetrain for a road vehicle, in particular for a hybrid vehicle, is provided. The drivetrain includes at least an electric motor, an electric energy accumulator, and an active connection to at least one drivable axle. In the recuperation mode, thus, when an electric motor is operating as a generator for generating electric energy for charging an electric energy accumulator, the generated electric energy is transmitted at least partly to at least one electric heating resistor in order to convert the energy into heat. | 01-15-2009 |
| 20090124452 | Method for Starting a Piston Engine and Hybrid Drive for Performing the Method - A method is provided for starting a piston engine of a hybrid drive in an electric travel state. The hybrid drive includes at least the piston engine, an electric motor, a transmission, and a clutch situated between the piston engine and the electric motor. A converter lockup clutch, which is switchable into a slip state, is also provided. A slip is set at the converter lockup clutch, and a speed of the electric motor is then increased. The speed and the torque either do not change or only change in a predefined range at the output side of the converter lockup clutch. The clutch is closed to transmit a torque pulse, so that a first top dead center of the piston of the piston engine may be overcome. A predefined slip is then set at the clutch. | 05-14-2009 |
| 20090188459 | PROCESS AND SYSTEM FOR STARTING A DIRECT-INJECTING INTERNAL-COMBUSTION ENGINE AS WELL AS MOTOR VEHICLE - A process for starting a direct-injecting internal-combustion engine is disclosed. The process includes triggering a separate drive for adjusting the camshaft for causing an angular position change between the crankshaft and the camshaft until the separate drive rotates the crankshaft such that a working medium is compressed by a piston in a cylinder of the internal-combustion engine. The position of the pistons of the internal-combustion engine is determined by using position determining devices to identify the cylinder of the internal-combustion engine in which the working medium is compressed. Fuel is injected into the cylinder in which the working medium is compressed when the cylinder is in a proximity of an upper dead center to start the internal-combustion engine. | 07-30-2009 |
| 20100073156 | DISPLAY DEVICE - A display device for a motor vehicle having an internal combustion engine for at least temporarily driving the motor vehicle, and for displaying operating-time-related data of the internal combustion engine. The display device is characterized in that the operating-time-related data are provided as portions of the operation of the motor vehicle with a switched-off internal combustion engine at entities (E, E′, E″, . . . ) occurring earlier on the route of the motor vehicle. The display device is configured to display these data in the manner of a histogram. | 03-25-2010 |
| 20100087978 | METHOD FOR OPERATING A DRIVE TRAIN - A method is provided for operating a motor vehicle drive train having an internal combustion engine, an electric motor and an electrical energy storage. An actual charge state of the electrical energy storage is detected and compared with an established setpoint charge state to determine one of several operating modes for the drive train. The setpoint charge state is determined as a function of an instantaneous driving state of the motor vehicle so that conclusions can be drawn about imminent deceleration, imminent acceleration or imminent cruise control, instantaneous transmission data and/or instantaneous hybrid drive data. Range boundaries and/or range extents of operating modes are shifted as a function of the setpoint charge state. | 04-08-2010 |
| 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 |
