Patent number: 9197125Abstract: Damage to an inverter due to an excessively high start-up current, when using space vector control without a voltage sensor in conjunction with small connection inductances, can be prevented with a method for controlling the inverter, and with a corresponding controller, wherein the controller is configured to transmit in a start-up phase of an inverter circuit a control signal to a control input of the inverter circuit, wherein the control signal simultaneously switches three first semiconductor switches, which are connected to a first DC voltage terminal of the inverter circuit, temporarily into a conducting state.Type: GrantFiled: April 24, 2013Date of Patent: November 24, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Georg Bachmaier, Christian Bachmann, Dominik Bergmann, Matthias Gerlich, Mirjam Mantel, Guillaume Pais

Publication number: 20150224880Abstract: A method for driving a vehicle comprising at least two motors is provided. If a plurality of motors are fed from an intermediate circuit via inverters, the current in the intermediate circuit has a plurality of harmonics (?5th, ?3th, ?1st, +1st, +3rd, +5th). To prevent coupling capacitors of the intermediate circuit becoming over-burdened, the switching frequency of the inverters is shifted in such a manner that the harmonics no longer fall into a resonance range.Type: ApplicationFiled: August 21, 2013Publication date: August 13, 2015Inventors: Georg Bachmaier, Christian Bachmann, Dominik Bergmann, Marco Cyriacks, Matthias Gerlich, Guillaume Pais, Alexandru Popescu

Patent number: 9013126Abstract: In order to store excess kinetic energy, an energy storage device and an operating method are described, in which the kinetic energy can be partially converted into electrical energy by a first electric machine using at least two electric machines arranged on a shaft and can be partially converted into additional kinetic energy, such as rotational energy, by a second electric machine. The method for energy storage of excess kinetic energy provides for converting kinetic energy partially into electric energy and partially into additional kinetic energy, such as rotational energy.Type: GrantFiled: September 10, 2010Date of Patent: April 21, 2015Assignee: Siemens AktiengesellschaftInventors: Georg Bachmaier, Dominik Bergmann, Matthias Gerlich, Guillaume Pais, Christian Tump

Publication number: 20150039166Abstract: In order to achieve a vehicle wheel (10) slip relative to a roadway (12) while braking the vehicle, said slip being as advantageous as possible, the rotational speed (w) of the wheel (10) can be actively reduced by an ABS by means of a braking intervention and passively allowed to accelerate again via the roadway (12) when the brake is released. The slip of the wheel (10) oscillates by an optimal slip value during the ABS regulating process. The aim of the invention is to improve an anti-lock braking system for a vehicle. In the method according to the invention, at least one wheel (10) of the vehicle is supplied with a braking torque (Mb) in order to temporarily reduce a travel speed (v) of the vehicle relative to a rolling surface (12), said braking torque acting against a rotating direction (14) of the wheel (10).Type: ApplicationFiled: August 16, 2012Publication date: February 5, 2015Inventors: Dominik Bergmann, Ludger Fiege, Gunter Freitag, Matthias Gerlich, Stefan Grieser-Schmitz, Eugen Lanze, Ries Robinson

Patent number: 8905334Abstract: A stroke translator or an injector having a solid-state actuator for generating a stroke and a hydraulic system for the hydraulic transmission of the stroke of the solid-state actuator to a control element such as a jet needle of a valve. The hydraulic system has hydraulic volumes hermetically sealed to the outside by metal bellows and constitute a hydraulic bearing with compensation for play. The advantages over known hydraulic levers are such that a complete metal seal is provided, and that a lower-wear design can be realized. Furthermore, a modular structure can be produced.Type: GrantFiled: February 25, 2010Date of Patent: December 9, 2014Assignee: Siemens AktiengesellschaftInventors: Georg Bachmaier, Gerit Ebelsberger, Bernhard Fischer, Matthias Gerlich, Michael Höge, Wolfgang Zöls

Patent number: 8096522Abstract: A pressure regulator can be used particularly in a CNG-operated motor vehicle as an electronically controlled pressure reducer for maintaining the gas pressure constant on the injection valve used for filling the respective cylinder. The pressure regulator is composed of a control unit (1), a pressure reducer (3) that is controlled by the control unit (1), and a throttle (2) which connects the gas outlets (20, 40) of the working chamber (17) of the control unit (1) and the pressure reducer (3). A piezoelectric actuator (11) which affects the valve (21, 22) of an overflow device (14) makes it possible to specifically modify the gas pressure (P2) in the working chamber (17) of the control unit (1) and simultaneously influence the position of the valve (38, 39) of the overflow device (33) of the pressure reducer (3), thus allowing the output pressure (Pout) of the pressure reducer (3) to be adjusted to a predefined desired value.Type: GrantFiled: April 5, 2007Date of Patent: January 17, 2012Assignee: Siemens AktiengesellschaftInventors: Georg Bachmaier, Gerit Ebelsberger, Matthias Gerlich, Michael Höge, Erhard Magori, Randolf Mock, Harry Schüle, Stefan Treinies
