    摘要: A device for picking up the position of an angle of a rotating part which is provided with angle markers 11 or teeth being simultaneously distributed over its circumference, whereby at least one angle marker and/or intermediate space between two angle markers is shaped differently serving as a reference marker 12. This can be realized, for example, by a wide or smaller angle marker or gap between two angle markers. The distance between two angle marker flanks is picked up by a counter 17 which counts a cycle frequency, whereby the counter is a free running continously counting counter. The instantaneously present counter level is transmitted into a storage 18 for each angle marker flank (ascending flank or rear flank) to be evaluated. Subtractions of two successive storage values and comparisons of successive corresponding differential values are performed for recognizing a reference marker. A reference marker signal is generated during a deviation of a differential value by a predetermined dimension from the established differential value, preferably before or after.

    摘要: To permit change of data, to be used in a fixed program carried out by a microprocessor (1) in accordance with a stored program (2), upon change in operating characteristics of a controlled apparatus (M), for example an internal combustion engine, an erasable programmable read-only memory (3) is provided, which is external to the microprocessor (1). The external memory (3) forms a combined address and data memory having at least one address field (4), and a vector field (5). A constant data field (7) and a table, or function data field (6) are part of the external memory (3), which data fields contain data to be addressed directly through the address field or via the vector field for not only a single type or series of apparatus, such as ICEs, but also additional engines, or engine characteristics, for example due to aging. In order to run the program by the microprocessor 1, with a changed or aged engine, then, it is only necessary to change the address of the data in the data field and/or the vector field to provide different output data for any given programming step.

    摘要: A transmitter wheel is used for example to detect speed changes of an internal combustion engine with high precision in order to calculate a running imbalance value from them. A transmitter wheel of this kind has for example three segments, which are ideally the same length, but in reality usually have lengths which differ slightly from one another. In order to prevent measurement errors which are caused by this, it is known to determine the actual lengths by means of an adaption process. The device according to the invention is embodied such that for each segment, it has a plurality of adaption filters to detect different adaption values for different speed ranges. It has namely turned out that in different speed ranges, different lengths are measured, which is an error that must be compensated for since the length of a segment is in fact actually constant.
