  • Patent number: 9523627
    Abstract: A method for determining segment times of a sensor wheel of an internal combustion engine, the sensor wheel being non-rotatably connected to a crankshaft of the internal combustion engine, marks being situated along the circumference of the sensor wheel, and the crankshaft of the internal combustion engine covering predetermined angle ranges during the segment times. Tooth times are determined as time intervals between two marks of the sensor wheel; a low-pass filtering is applied to the determined tooth times, and filtered tooth times are determined as a result of the low-pass filtering. Segment times of the sensor wheel are determined as a sum of filtered tooth times of a certain number of successive marks of the sensor wheel.

  • Patent number: 8327694
    Abstract: Disclosed is a method for adapting mechanical tolerances of a timing wheel of a sensor unit of an internal combustion engine of a hybrid drive of a vehicle, the hybrid drive having at least one second motor, in particular an electric motor, in addition to the internal combustion engine, and the internal combustion engine being operated in a desired operating mode during adaptation operation. It is provided that the desired operating mode is performed in such a way that the internal combustion engine is driven using the second motor, in particular an electric motor, and no fuel is supplied to the internal combustion engine. A corresponding device is also disclosed.

  • Publication number: 20120041667
    Abstract: In a method for operating an internal combustion engine having a first injection valve for a first combustion chamber and a second injection valve for a second combustion chamber, the engine is operated in a first operating mode in which the fuel is injected by the first and by the second injection valve, and a first operating characteristic of the engine is determined during the first operating mode. The engine is further operated in a second operating mode in which injection of fuel by the first injection valve is suppressed, and a second operating characteristic of the engine is determined during the second operating mode. The first and second operating characteristics are compared, and, as a function of the comparison, the engine is operated in the second operating mode or in a third operating mode in which injection of fuel by the second injection valve is suppressed.

  • Patent number: 7436186
    Abstract: A method for generating a simulated sensor signal pattern for a marking gap of a signal-generating disk which is coupled with a crankshaft of an internal combustion engine, the signal-generating disk having a marking by the alternating positioning of teeth and tooth interstices, and the marking gap being formed by an enlarged tooth interstice or an enlarged tooth, and at least one sensor being assigned to the signal-generating disk, the sensor in each case being able to generate an electrical signal that is able to assume at least two signal levels (high, low), one of the signal levels (high, low) being assigned to a tooth and the other to a tooth interstice, and a simulated sensor signal pattern being approximated for the marking gap from the signal pattern of the signal generated by the sensor, wherein the signal pattern lying before the marking gap in time is used for the approximation.

  • Publication number: 20080212668
    Abstract: A method for serial data transmission from a transmitter to a receiver has the following steps: a) establishing at least one digital data word which is representative of a data value to be transmitted; b) establishing a pulse duration which is proportional to a non-negative integer represented by the data word plus a constant positive allowance; c) transmitting a pulse (IH, IM, IL) having the established pulse duration from the transmitter to the receiver; and d) detecting the pulse duration at the receiver and reconstructing the data word.

  • Publication number: 20020178209
    Abstract: A method and a device for determining the load of a computing element. A computer program is executed on the computing element. The computer program is subdivided into several tasks, and each task includes at least one process. To be able to determine, on the one hand, the load of the computing element as precisely and reliably as possible and with a high dynamic performance and, on the other hand, the processing time of processes or tasks of the computer program independently of interruptions by processes of higher priority tasks, it is proposed that a time interval be selected such that at least one task is started and ended during the time interval; the running time of the task be determined during the time interval after completion of the task or every task; and the running time of the task or of every task be subtracted from the determined running time in the event that the completed task was interrupted by at least one additional task.
