Patent number: 9075455Abstract: A method for determining the relative position of an object in an area in six spatial degrees of freedom is provided. A marker pattern with at least three markers is applied on the object, and an optical detecting device is provided with a two-dimensional sensor surface. The object is moved in the detection region of the optical detecting device such that the marker pattern can be detected by the detecting device, images of the markers are projected onto image positions on the sensor surface, and the image coordinates of the markers are ascertained. The relative position of the marker pattern is determined by analyzing the image coordinates. The position of an invariant point is ascertained on a reference circle on a reference plane, and describes a unique relationship between a coordinate system assigned to the marker pattern and a coordinate system assigned to the detecting device.Type: GrantFiled: April 24, 2012Date of Patent: July 7, 2015Assignee: Eberhard Karls Universitaet TuebingenInventors: Andreas Masselli, Karl Engelbert Wenzel, Andreas Zell

Publication number: 20150143944Abstract: An accelerator pedal unit (1) for a motor vehicle includes an accelerator pedal (11) for controlling a propelling force of a motor of the motor vehicle, and a return spring. A position change of the accelerator pedal (11) from its starting position caused by an actuating force against a restoring force exerted by the return spring results in an increase of the propelling force of the motor, and the restoring force of the return spring returns the accelerator pedal (11) toward its starting position when the actuating force subsides. A friction device (100, 200, 300, 400, 500, 600) generates a friction force that acts in addition to the restoring force. Alternatively, an electromechanical main actuator (18) produces an additional restoring force (FZusatz) that can be variably controlled using a control unit (12).Type: ApplicationFiled: May 22, 2013Publication date: May 28, 2015Inventors: Andreas Zell, Carmelo Leone, Mihaly Szasz, Norbert Silberleitner, Johannes Heydenreich, Nobuaki Okumoto

Patent number: 8914210Abstract: A device for generating an additional reset force on the gas pedal for motor vehicles, wherein a position change of the gas pedal relative to the initial position thereof, induced by a corresponding actuating force, against a reset force leads to an increase in the motive power of the engine and, when there is a decrease in the actuating force, a reset force moves the gas pedal back in the direction of the initial position thereof, and wherein an actuator is provided, which applies an additional reset force that acts in the reset direction of the gas pedal, and wherein the motor vehicle has a unit for determining the shifting point of a manually shifted transmission. Moreover, the invention relates to a method for operating the device according to the invention.Type: GrantFiled: November 3, 2010Date of Patent: December 16, 2014Assignees: Continental Engineering Services GmbH, Conti Temic Microelectronic GmbHInventors: Gregor Schmitt, Frank Drews, Andreas Zell, Thorsten Gerbig

Publication number: 20130047776Abstract: A drive pedal unit for motor vehicles, wherein a position change of the pedal plate brought about by a corresponding actuating force, with respect to the starting position thereof against a restoring force of a restoring spring, leads to an increase of the drive force of the engine and, when the actuating force decreases, the restoring force of the restoring spring returns the pedal plate in the direction of the starting position thereof. An externally controllable electro-mechanical actuator is arranged such that an additional restoring force may be set on the pedal plate. A hysteresis of the pedal characteristic curve is produced and is independent of the additional restoring force of the electromechanical actuator. A friction surface cooperates with a friction element, wherein the friction surface is connected to the pedal plate, whilst the friction element is decoupled from the power flow between the pedal plate and the electromechanical actuator.Type: ApplicationFiled: May 10, 2011Publication date: February 28, 2013Inventors: Carmelo Leone, Andreas Zell, Mihaly Szasz, Mihai Duca, Ciprian Dragoi

Patent number: 8364348Abstract: A method for determining a steering angle offset (LWO) in a vehicle having a steering unit and a steering angle sensor. A first frequency distribution (HV1) of the steering angle (LW) is determined over a number of steering angles according to at least one dynamic vehicle parameter (Q, G, V), and the average value (MW1) of the steering angle (LW) is determined from the first frequency distribution (HV1). The next step tests whether the steering angle (LW) in the first frequency distribution (HV1) is distributed symmetrically around the average value (MW1) and, when there is symmetry of the first frequency distribution (HV1) around the average value (MW1), the first frequency distribution (HV1) is carried over into a second frequency distribution (HV2). When the overall number of steering angles (LW1) in the second frequency distribution (HV2) exceeds a prespecified threshold value (S), the steering angle offset (LWO) is determined from the average value (MW2) of the second frequency distribution (HV2).Type: GrantFiled: December 20, 2007Date of Patent: January 29, 2013Assignee: Continental Teves AG & Co. oHGInventors: Andreas Zell, Jörg Grotendorst

Publication number: 20120167708Abstract: A device and method for generating an additional restoring force at the gas pedal for motor vehicles, wherein a change in position of the gas pedal relative to its initial position, brought about by a corresponding activation force counter to a restoring force, leads to an increase in the driving force of the drive engine, and when the activation force diminishes a restoring force returns the gas pedal in the direction of its initial position. An actuator element is provided which applies an additional restoring force which acts in the restoring direction of the gas pedal. For energy efficiency, the invention provides that the magnitude of the additional restoring force (F) acting on the gas pedal is configured such that the gas pedal assumes a position which moves the operating point of the drive engine into a region with a relatively high efficiency level.Type: ApplicationFiled: July 7, 2010Publication date: July 5, 2012Applicant: Conti Temic Microelectronic GmbHInventors: Thomas Brandt, Frank Drews, Tobias Düser, Jens Schröter, Christian Zingel, Alexander Schwarz, Sascha Ott, Andreas Zell, Carmelo Leone

Publication number: 20040057543Abstract: A main-remote radio base station system includes plural remote radio units each having a remote digital interface unit and a main unit having a main digital interface unit. Different length links couple different remote radio units to the main unit. The digital interfaces in the main and remote units include a digital data channel and a digital timing channel. A delay associated with each link is determined without interrupting transmission of data over the digital data channel. The delays, reported continuously, periodically, or upon request, are compensated for and equalized by advancing a time when the timing and data signals are sent over their respective digital channels. In a preferred embodiment, the interface is a digital optical interface. A hybrid base station includes synchronized “near” and “remote” radio units.Type: ApplicationFiled: September 24, 2002Publication date: March 25, 2004Inventors: Arie Huijgen, Andreas Zell
