20090019772 | Method for Limiting the Excess Force of a Closing Part Which is Actuated by an External Force - In a method for limiting the excess force of a closing part of an adjusting device, the closing part is actuated by external force. An anti-jamming system determines, during an adjusting operation, current adjusting force values at least within a partial area of the adjusting path and respectively, in predetermined positions of the closing part, and compares the values to adjusting force comparative values which are already stored in a storage device. At least one of the stored adjusting force comparative values are adapted to mechanical technical conditions of the adjusting device and the extent of the adaptation is predetermined according to the service life. | 01-22-2009 |

20100097026 | METHOD AND DEVICE FOR TRACKING THE POSITION OF A COMPONENT DRIVEN BY AN ELECTRIC MOTOR - In order to track the position of a component driven by an electric motor, wherein rotational movements of the electric motor are detected and used for a position count, deviations from an anticipated position count are determined and added to the position given by the position count as an uncertainty region. | 04-22-2010 |
20100138046 | METHOD AND UNIT FOR OPERATING AN ELECTROMECHANICAL ADJUSTING DEVICE - In a method for operating an electromechanical adjusting device, having an actuating part driven by a controller controlled motor, and which can be adjusted according to a manual specification for a controller operating element between a first and a second end position, the controller detects the precise position of a blockage of an adjusting movement from fed sensor signals, wherein user action performed on the operating element adjusts the actuating part by a first movement directed toward the end position to a position at which mechanical blockage occurs in order to determine a reference position, and adjusts the actuating part by a second movement into the second end position to examine the validity of the previously determined reference position by a test program which decides whether an automatic operating mode, in which an actuating process runs automatically, is activated, or blocked, as a function of the test result. | 06-03-2010 |
20100179733 | METHOD AND DEVICE FOR DETECTING A JAM - For the purpose of detecting a jam during the adjustment of a component of a motor vehicle using an adjustment drive, wherein measured values related to the adjustment force (F) are compared to a threshold value (FREF) and when the threshold value is reached, the adjusting movement is slowed or stopped, and optionally reversed, it is proposed that the component speed or a parameter correlated therewith is detected and the threshold value (FREF) modified accordingly. | 07-15-2010 |
20100211273 | METHOD AND DEVICE FOR INCREASING THE PRECISION OF THE POSITION DETERMINATION OF A MOTOR-DRIVEN CLOSURE ELEMENT OF A VEHICLE - In a method and a device for increasing the precision of the position determination of a motor-driven closure element of a vehicle, the data corresponding to a force-displacement reference curve and the data corresponding to a force-displacement actual value curve are used, a correlation function is calculated, the maximum thereof is found, and the counter status of a position counter is corrected by using the position offset associated with the determined maximum. | 08-19-2010 |
20100223025 | METHOD AND DEVICE FOR BALANCING PRODUCTION-RELATED INACCURACIES OF THE MAGNETIC WHEEL OF AN ELECTROMOTIVE DRIVE OF A VEHICLE - In a method and a device for balancing production related inaccuracies of the magnetic wheel of an electromotive drive of a vehicle, correction factors are used, the initial value of which is factory preset, and which are modified in the course of an adaption process until the production-related inaccuracies of the magnetic wheel have been balanced as much as possible. | 09-02-2010 |
20100259249 | METHOD AND DEVICE FOR DETERMINING THE POSITION OF A MOBILE CLOSING PART OF A VEHICLE - In a method and a device for determining the position of a closing part of a vehicle, that can be moved by a direct-current motor, a motor current signal is derived from the direct-current motor and converted into a digital signal by an analog-digital converter. The signal is filtered and forwarded to a position counter for counting the current ripple. The scanning frequency of the analog-digital converter is modified according to the rotational speed of the direct-current motor. | 10-14-2010 |
