20150039949 | DRIVE TRAIN CONTROL - Various techniques relating to drive train control are disclosed. In an embodiment, in a first mode of operation communication between a controller and a submodule of the drive train takes place via a first communication channel and optionally additionally via a second communication channel. In a second mode of operation, upon failure of the first communication channel, communication with the submodule of the drive train takes place via the second communication channel. | 02-05-2015 |

20140042876 | Remote Rotor Parameter Sensor for Electric Drives - A rotor parameter sensor can be used for electric drives. A rotor of an electric engine or motor is monitored by a sensor sensing one or more physical observables or operation parameters. Furthermore, a method and system can be used for monitoring an electric engine or motor for use in electric or hybrid vehicles. | 02-13-2014 |
20140167654 | CIRCUIT ARRANGEMENTS AND METHODS FOR OPERATING AN ELECTRICAL MACHINE - A circuit arrangement is described comprising a first battery; a second battery; an electrical machine connected between the first battery and the second battery wherein the electrical machine is connected to the first battery via a first switching arrangement and the electrical machine is connected to the second battery via a second switching arrangement and a controller configured to control the first switching arrangement and the second switching arrangement such that a current that has a DC component flows through the electrical machine. | 06-19-2014 |
20150028817 | Battery Control with Block Selection - A battery block is equipped with a plurality of battery blocks. Each of the battery blocks includes at least one battery cell to provide a block voltage of the battery block. A first number of the battery blocks is selected, and the first number of the battery blocks is coupled to voltage terminals of the battery to set a battery voltage which corresponds to the sum of the block voltages of the first number of battery blocks. Further, a second number of the battery blocks is selected, and the second number of battery blocks is coupled to the voltage terminals of the battery to set a battery voltage which corresponds to the sum of the block voltages of the second number of battery blocks. | 01-29-2015 |
20150055258 | DRIVING CIRCUIT FOR AN ELECTRIC MOTOR - In various embodiments a circuit arrangement is provided, having a bridge circuit including at least two switches connected in series; a bridge node which may provide a phase voltage arranged between the at least two switches; an electric motor having at least one phase winding coupled with the bridge node; a decoupling switch; a controller, wherein in an error case the controller may be configured to switch off the at least two switches, to determine whether a predefined condition is satisfied, and to one of delayed switching off the decoupling switch; and switching off the at least two switches and the decoupling switch simultaneously, depending upon whether the predefined condition is satisfied; wherein the controller may determine that the predefined condition is satisfied when the decoupling switch may be switched off without damage from the current applied to it when the at least two switches are switched off. | 02-26-2015 |

20140150641 | AXIAL PISTON MACHINE HAVING A CONICAL PISTON - An axial piston machine includes a housing, a drive shaft, and a cylinder drum. The drive shaft is mounted in the housing so as to be rotatable with respect to a first axis of rotation. The cylinder drum is mounted so as to be rotatable with respect to a second axis of rotation. The cylinder drum has at least one cylinder bore that linearly guides an elongate piston. The piston has a first end connected to the drive shaft by a ball joint and a section in the form of a circular cone which tapers toward the first end. The piston also has a spherical section at the second end that is situated opposite the first end. The cone-shaped section merges without offsets and kinks into the spherical section. The piston has a flat end face at the second end which defines a plane that intersects the spherical section. | 06-05-2014 |
20140150642 | AXIAL PISTON ENGINE WITH AN INCLINED CYLINDER BORE - An axial piston engine, in particular pump or motor, includes a housing, a drive shaft, and a cylinder drum. The drive shaft is mounted in the housing so as to be rotatable with respect to a first axis of rotation. A bearing body is received in the cylinder drum rotatably with respect to a second axis of rotation. The bearing body is connected to the drive shaft via a first ball joint that has a joint center lying on the first axis of rotation. The cylinder drum has at least one circular-cylindrical cylinder bore in which an elongated piston is displaceably received. A first end of the piston is connected to the drive shaft via a second ball joint. The at least one cylinder bore is arranged at an inclination to the second axis of rotation. | 06-05-2014 |
