Publication number: 20080201559Abstract: A cost-effective safety concept for safety-relevant applications in motor vehicles accordingly activates a load not directly from a central unit, but instead indirectly via a switching device. The latter has a first and a second register for the acquisition of the same control data from the central unit, and a third register for outputting data to the load. A transmission device transmits data from the second register to the third register. A first comparison logic compares a content of the second register with that of the third register and sends an interrupt to the central unit, when the two contents are not identical. A second comparison logic compares the content of the first and second registers and enables the transmission device, when the contents of the two registers are identical and otherwise blocks the transmission device. The last held state is thus maintained in the event of an error.Type: ApplicationFiled: February 19, 2008Publication date: August 21, 2008Applicant: VDO AUTOMOTIVE AGInventor: Bernhard Forstl

Publication number: 20080183929Abstract: A method of transmitting data on a data line between a central control device and a decentralized data processing device. During a normal operation of the system, the central control device periodically sends synchronization pulses to the at least one data processing device via the data line in order to request data packets, and the decentralized data processing device sends the data thereof to be transmitted, as data packets, to the central control device, following the synchronization pulse. The data line is embodied as a data bus. Each of the decentralized data processing devices is configured by the central control device before the first transmission of data packets to the central control device. In order to configure the system, a bi-directional communication is carried out between the central control device and the at least one decentralized data processing device.Type: ApplicationFiled: March 28, 2006Publication date: July 31, 2008Applicant: SIEMENS VDO AUTOMOTIVE AGInventor: Wolfgang Gottswinter

Publication number: 20080154560Abstract: A method for stimulating wheel electronics systems of single tires of at least one tire group in a motor vehicle. The wheel electronics systems are stimulated with a low frequency trigger signal, as follows: a trigger signal is emitted from an LF trigger to the wheel electronics systems of the relevant tire group at a variably adjustable first transmission field strength. Radio frequency signals are transmitted from those wheel-side wheel electronics systems, at which a sufficiently high transmission field strength of the trigger signal has arrived containing an item of trigger information, to a vehicle-side receiving unit. A determination is made of the number of RF signals received by the vehicle-side receiving unit, each containing one item of trigger information.Type: ApplicationFiled: December 19, 2007Publication date: June 26, 2008Applicant: SIEMENS VDO AUTOMOTIVE AGInventors: Alexander Fink, Frank Fischer, Gregor Kuchler

Publication number: 20080137319Abstract: A motherboard is shielded by way of a shielding metal sheet. A shielding metal sheet according to the invention is embodied such that the dimensions thereof in the longitudinal and transverse direction do not exceed the dimensions of the motherboard, thus advantageously allowing the shielding metal plate to be mounted directly on the motherboard. By directly mounting the shielding metal plate on the motherboard, the motherboard can also be transported or mounted on a main board as a unit along with the protecting shielding metal plate. The novel device is particularly suitable for decentralized parts production processes and finishing processes of entire shielded electronic systems requiring a lot of components, especially for applications in motor vehicles.Type: ApplicationFiled: November 22, 2005Publication date: June 12, 2008Applicant: SIEMENS VDO AUTOMOTIVE AGInventors: Werner Bobrowski, Claus Peter, Dietmar Schlegel, Johann Schneeberger

Patent number: 7376402Abstract: A radio receiver having an FM band tuner, an AM band tuner, a controller coupled to both said tuners, and a radio data (RD) decoder for providing radio data. The RD decoder is coupled for receiving radio data from at least one of the tuners which is tuned to a radio program. The RD decoder is coupled to the controller for switching the radio receiver from FM band to AM band or vice versa based on radio program frequency correspondence data included in the radio data. The radio receiver is advantageous since it allows for automated cross switching between different frequencies whereon a same radio program is broadcast. This is particularly advantageous if the radio receiver, such as placed in a car, leaves the broadcast coverage area. User intervention is thus obviated.Type: GrantFiled: June 11, 2003Date of Patent: May 20, 2008Assignee: VDO Automotive AGInventors: Jean-Pierre Lecomte, Frits De Jong

Publication number: 20080033608Abstract: The present invention relates to a method and a device for assigning an electronic wheel unit, which is assigned to a wheel of a vehicle and is for ascertaining at least one characteristic parameter of the wheel, to a side of the vehicle. In this case, a direction of rotation of the wheel is determined by means of the wheel unit. The direction of rotation of the wheel which is determined by means of the wheel unit is compared with a direction of rotation of another wheel which is determined by means of another wheel unit assigned to the other wheel, wherein the wheel and the other wheel are arranged on different sides of the vehicle on a shared axle. Depending on the comparison of the determined directions of rotation of the wheel and of the other wheel, the wheel unit is assigned on the basis of a first procedure for assigning the wheel unit to the side of the vehicle or on the basis of a second procedure for assigning the wheel unit to the side of the vehicle.Type: ApplicationFiled: August 7, 2007Publication date: February 7, 2008Applicant: SIEMENS VDO AUTOMOTIVE AGInventors: Water Baumgartner, Frank Fischer

Patent number: 6611888Abstract: In a data memory (2) which is arranged in a vehicle, an interface (6), which is equipped with a plug connection (5), is used to connect a receiver unit (1). The individual software modules which, depending on the design, are necessary for decoding the signals of the receiver unit (1) may be called up by means of a memory unit (7) for the data memory (2). The memory unit (7) is arranged at the interface (6). A precautionary storage of all the relevant software modules in the data memory (2), and the associated laborious manual configuration can thus be eliminated and incorrect assignment of the software module to the existing receiver unit (1) may be avoided. At the same time, new developments in the field of software modules may be incorporated into already existing data storage systems without difficulty.Type: GrantFiled: September 1, 1999Date of Patent: August 26, 2003Assignee: Siemens VDO Automotive AGInventor: Lutz-Wolfgang Tiede
