20110181056 | CIRCUIT AND METHOD FOR PREVENTING INADVERTENT OPENING OF A VEHICLE DOOR - Described herein is a circuit arrangement for a motor vehicle door having a detent mechanism which keeps the motor vehicle door in the closed position and opens it and at least one operating element, for example, an outer door handle and/or inner door handle, wherein an electric drive, for example, an electric motor, drives the detent mechanism, and the motor can be connected by means of a control module. In one embodiment, at least one electrical switching element is arranged in the circuit of the motor. In another embodiment, when the operating element is operated, the electrical circuit of the motor can be completed by means of the electrical switching element. Also described is a method for actuating a detent mechanism in a motor vehicle door and a controller for a detent mechanism which keeps a motor vehicle door in the closed position or opens it. | 07-28-2011 |
20110271595 | DRIVE ARRANGEMENT FOR MOTOR-OPERATED ADJUSTMENT OF A CLOSURE ELEMENT IN A MOTOR VEHICLE - Disclosed herein is a drive arrangement for motor-operated adjustment of a closure element in a motor vehicle having at least one drive with a drive motor, and a drive controller. The closure element can be driven in the motor-operated adjustment mode by the drive motor in the closing direction and in the opening direction between a closed and an open position. The drive is non-self-locking and has a sensor, in particular a Hall sensor, for sensing the drive movement. The drive controller monitors the sensor signals for a fault state, and when a fault state is sensed initiates an emergency braking and/or stop mode. The drive arrangement comprises two drives each with a sensor for determining the respective drive movement. To detect fault-induced slamming shut of the closure element, the drive controller correlates the sensor signals of the two sensors, in particular compares said sensor signals. | 11-10-2011 |
20120146556 | DRIVE ARRANGEMENT FOR THE MOTOR-DRIVEN ADJUSTMENT OF AN ADJUSTABLE ELEMENT IN A MOTOR VEHICLE - Described herein is a drive arrangement for the motor-driven adjustment of an adjustable element in a motor vehicle, the drive arrangement having two electrical drives and a control device, the drives, in the fitted state, acting in the same way on the adjustable element and having a substantially identical configuration, apart from tolerance-related discrepancies. The control device has a power controller which, in the fitted state, during the motor-driven adjustment of the adjustable element, subjects the electrical power that is output respectively to the two drives to closed-loop control, for the purpose of compensating for the tolerance-related discrepancies, in such a way that an identical electrical power consumption is established for both drives. | 06-14-2012 |
