  • Patent number: 7995620
    Abstract: A method for transferring data between a data transmission system and a processor of a participant in the data transmission system. All components of the data transmission system are synchronized to a common global time base. The operating system time base of the participant processor is synchronized to the global time base of the data transmission system at least prior to a data transfer, and, to this end, a synchronization clock pulse that is synchronous to the global time base of the data transmission system is provided for synchronizing the operating system time base. This synchronization clock pulse may be provided by a hardware and/or software arrangement. In a data transmission system for implementing the method, the synchronization clock pulse is provided by suitable arrangement(s) of the communications controller and applied to the host processor via a synchronization line.

  • Patent number: 7864078
    Abstract: A method and a device for decoding a signal transmitted via at least one transmission line of a data transmission system, in a user of the data transmission system receiving the signal. Instead of at discrete instants, as currently done, sampling at a specific sampling instant does not take place. To this end, a potential-edge position (PEP) for an imminent edge is estimated first. Then, given n-fold oversampling, maximally n sampling values before the PEP and maximally n sampling values after the PEP are determined and compared with previously recorded and stored sampling values. The stored sampling values are preferably stored in an edge-acceptance vector (EAV) and correspond to an edge change of the signal to be decoded at a particular point in time. Preferably not all detected 2n sampling values are compared to the content of the EAVs, but the comparison is limited to a portion, combined to a sensitivity range, of the 2n sampling values of each EAV.

  • Publication number: 20100205473
    Abstract: A method for synchronizing two communication networks of an electronic data-processing system. One or a plurality of nodes is connected to the two communication networks in each case. Each of the two communication networks has a schedule, which specifies at least one time slot for a synchronization message. One of the nodes of the first communication network, and one of the nodes of the second communication network are linked to one another by a shared arithmetic unit. A deviation between the time slots for the synchronization messages on the two communication networks is determined as a function of the schedules of the two communication networks. The deviation is used to determine correction values, which are forwarded to at least one other node. The occurrence of the time slots for the synchronization messages is modified by the other node as a function of the correction values.

  • Publication number: 20100195672
    Abstract: A method for diagnosing a synchronization of two communications networks of an electronic data-processing system, each communications network including at least one node and having a respective schedule that specifies at least one respective time slot for a respective synchronization message, may include detecting, by each of the two communications networks, an individual time-based variable, comparing the two detected time-based variables to each other, and determining a quality of the synchronization of the two communications networks based on the comparison.

  • Publication number: 20100195671
    Abstract: A method for synchronizing two communication networks of an electronic data-processing system, each of the networks including one or more respective nodes, may include establishing for each of the networks a respective time schedule that establishes at least one respective time slot for a respective synchronization message. The synchronization message time slots are established to coincide. The synchronization message of the first communication network is generated by one of the nodes of the first communication network. The synchronization message of the second communication network is generated as a function of the synchronization message of the first communication network.

  • Publication number: 20100054282
    Abstract: A method is for transferring data between a data transmission system and a processor of a participant in the data transmission system. All components of the data transmission system are synchronized to a common global time base. The operating-system time base of the participant processor is synchronized to the global time base of the data transmission system. To render possible a synchronization of the operating-system time base to the global time base in complex data transmission systems as well, it is provided that the operating-system time base of the participant processor be synchronized to the global time base of the data transmission system at least prior to a data transfer, and, to this end, that a synchronization clock pulse that is synchronous to the global time base of the data transmission system be provided for synchronizing the operating-system time base. This synchronization clock pulse is provided by a suitable arrangement that is implemented as hardware and/or software.

  • Publication number: 20100046594
    Abstract: In a method and a device for decoding a signal, the signal is transmitted via at least one connecting line of a data transmission system, in a user of the data transmission system receiving the signal. It is provided to measure the interval of a change—provided compulsorily in a transmission protocol used in the data transmission system—of the signal from rising to falling or from falling to rising edge. A tendency for an asymmetrical delay of the signal can be ascertained from the measured interval. The sampling of the bits of the received signal can be improved as a function of the interval or of the asymmetrical delay, for example, by setting the sampling instant in variable fashion. Alternatively, the interval or the asymmetrical delay can be utilized for diagnostic purposes.

  • Publication number: 20100008456
    Abstract: A method and a data-transmission system for transmitting data encoded in a signal between a transmitting user and a receiving user of the data-transmission system via a network structure of the data-transmission system. The data encoded in the signal are serially transmitted bit-by-bit in data frames having a defined structure. Each bit of the data encoded in the signal is sampled in the receiving user. Due to the transmission via the network structure, the signal is delayed asymmetrically. To compensate for the asymmetrical delay on the physical layer in the transmission channel, it is provided that the asymmetrical delay of the signal is determined at at least one point in the network structure, and is at least partially compensated prior to the receiving user sampling the bits of the data encoded in the signal. A measuring and compensating device is provided to measure and compensate for the asymmetrical delay.

  • Patent number: 7016780
    Abstract: In an internal combustion engine, fuel is injected directly into a combustion chamber by an injector that has a piezoactuator. An electrical charge conveyed to and/or removed from the piezoactuator is ascertained by a method that is calibrated at least once during an operating time span of the internal combustion engine. To allow the calibration to be carried out or performed as often as possible, the method for ascertaining the electrical charge transferred to and/or removed from the piezoactuator may be calibrated during at least one triggering off-time (dtK) of the piezoactuator while the internal combustion engine is operating.

  • Patent number: 6983731
    Abstract: A method for operating a fuel injection system for an internal combustion engine is provided, in which monitoring is performed as to whether an overlapping occurs between a time interval in which one piezoelectric element for injecting fuel into a cylinder is to be charged or discharged, and a time interval in which a different piezoelectric element for injecting fuel into a different cylinder is to be charged or discharged. The monitoring is performed as to whether, in the context of a lower-priority injection, the charging or discharging occurs within a predefined time interval around the point in time of a charging or discharging of a higher-priority injection, the spacings of time-related charging and/or discharging edges (edge overlaps) being determined during operation of the fuel injection system, and the magnitude of the shift and/or shortening of the lower-priority injections with respect to the higher-priority injections being determined therefrom.
