Patent number: 8766574Abstract: A method and a control device operate a three-phase brushless direct current motor with phase windings that are fed by an inverter connected to a voltage source having a high potential and a low potential. The semiconductor switches of the inverter are arranged in a bridge circuit and are controlled such that current always flows through two phase windings during motor operation. The motor is operated with normal commutation when the rotational speed is greater than or equal to a minimum rotational speed, wherein the angles are shifted by 60°. During start-up operation, up to the minimum rotational speed, a high-potential-side commutation angle of a phase winding is shifted toward a low-potential-side commutation angle of the phase winding by an angle greater than 0° and less than or equal to 60° with respect to the normal commutation.Type: GrantFiled: November 6, 2012Date of Patent: July 1, 2014Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 8670899Abstract: A method for detection of a control event by a sensor arrangement having at least one sensor element and a sensor controller is described. The sensor controller digitizes sensor signals into sensor measured values. An operator control event is produced by a user and a first coarse evaluation for a sign of operator control is performed and a predetermined number of sensor measured values are progressively buffer-stored in a buffer store wherein detection of a sign of operator control initiates a fine evaluation of the sensor measured values to verify the occurrence of an operator control event at an initiation time. The fine evaluation is based on the buffer-stored sensor measured values and on subsequent sensor measured values, so that the fine evaluation includes sensor measured values both before and after the initiation time.Type: GrantFiled: March 11, 2011Date of Patent: March 11, 2014Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 8669726Abstract: The invention in certain embodiments relates to a control circuit for an electric-motor-operated window lifter (10) of a motor vehicle (1), the control circuit having a first switch (11) for opening a vehicle window (7), a second switch (12) for closing the vehicle window (7), and a control device (15), which, when one of the switches (11, 12) is activated, actuates the window lifter (10) to move the vehicle window (7) in the opening direction or closing direction. The control device (15) monitors the lighting current (ILED) which flows across a lighting element (14) for the switches (11, 12), and generates a control signal (I12), if appropriate, for opening the vehicle window (7) if the lighting current (ILED) exceeds an overcurrent threshold value (IRef) thereby detecting inundation of the vehicle.Type: GrantFiled: January 22, 2010Date of Patent: March 11, 2014Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 8661735Abstract: The invention, in certain embodiments, specifies an actuation method for an electric window winder (10) of a front window (1) of a vehicle (3) without a B-pillar and with a moveable rear window (2), which actuation method allows all the windows to be closed in a particularly rapid and reliable manner. According to the method, provision is made for the front window (1) to be closed by the window winder (10), taking into consideration a trapping-prevention means (25). Furthermore, a closing condition is checked during the actuation method. If, on account of this closing condition, it can be assumed that trapping prevention-related reversing of the front window (1) has been caused by a collision with the rear window (2), the front window (1) is closed again after the trapping prevention-related reversing operation.Type: GrantFiled: November 4, 2009Date of Patent: March 4, 2014Assignee: Brose Fahrzeugteile GmbH & Co., KG., HallstadtInventor: René Zellmer

Publication number: 20130321006Abstract: A method measures a capacitance. According to the method, a first detection measurement for the capacitance which is to be measured is detected by a first measurement method during a first measurement phase. In this case, a second measurement phase is started when the first detection measurement satisfies a transition criterion. A second detection measurement for the capacitance which is to be measured is detected during the second measurement phase by a second measurement method which differs from the first measurement method. The second measurement method has higher measurement accuracy than the first measurement method but also greater energy expenditure.Type: ApplicationFiled: August 8, 2013Publication date: December 5, 2013Applicant: BROSE FAHRZEUGTEILE GMBH & CO.

Publication number: 20130271058Abstract: A method is specified for ascertaining an actuating position of a vehicle part that can be moved by an electric actuating motor. The speed of an actuating motor correlated therewith is acquired in a time-resolved manner during an actuation process. An initial no-load phase of the actuation process is identified, during which the actuating motor rotates while overcoming the system tolerance of the actuating mechanism without motion of the vehicle part. An actuating position measure for the actuating position of the vehicle part is ascertained from the motor rotation, with this measure being corrected during the no-load phase. By averaging over time, a test quantity is ascertained from the second derivative or the measured quantity correlating herewith. The end of the initial no-load phase is identified in this process when the test quantity exceeds a predetermined limit.Type: ApplicationFiled: April 12, 2013Publication date: October 17, 2013Applicant: BROSE FAHRZEUGTEILE GMBH & CO.
