    摘要: A pulse shaper for inductive transmitters, in particular inductive crankshaft angle transmitters on internal combustion engines is suggested, wherein a Schmitt-trigger is connected with the output of the transmitter. A peak value detector (D1,C) is connected with the output of the transmitter and means are provided which set the trigger threshold of the Schmitt-trigger in dependency on the output of the peak value detector.

    摘要: A pulse shaper for inductive pickups, in particular for inductive speed pickups or angle of rotation pickups on internal-combustion engines, is proposed, which has a voltage controlled voltage divider (14, 17, 19) at its input. A level adaptation takes place of the signal delivered by the inductive pickup (10) to a Schmitt trigger stage (44), at the output (57) of which a voltage jump occurs whenever the signal delivered by the pickup (10) rises above a certain value and falls below a certain value. The voltage divider at the input of the pulse shaper is formed by a resistor (14) and a first and second diode (17, 19), the differential resistance of which can be set by controlled voltage sources (24, 28). The special advantage of the circuit is that no higher voltage than the operating voltage of the pulse shaper can occur after the resistor 14 at the input. The pulse shaper is ideally suited for integration, as only easily integratable components are contained in the circuit.

    摘要: A method and a device for driving an electromagnetic consumer (device) which includes a movable element, in particular a solenoid valve for metering fuel into an internal combustion engine. Within a timing window, a switching instant is determined by evaluating the time characteristic of a variable which corresponds to the current flowing through the electromagnetic consumer. A clocked voltage control is provided within the timing window.

    摘要: To increase the versatility of a central processing unit (30) controlling an operating apparatus, such as apparatus including an engine, installed in an automotive vehicle, a main read-only memory (ROM, 40) stores not only operating data of the vehicle and/or the engine, but additionally, the organization program of the central processing unit (CPU, 30) in modular, or block form in the ROM (40). An auxiliary ROM (41) preferably an electronically erasable ROM is connectable, via an interconnection bus (80) to the CPU (30) and an initial program stored in the main ROM (40) provides a determination or recognition step to be carried out by the CPU (30) first, to determine if the auxiliary EPROM (41) is present; and, if so, to then address the auxiliary EPROM (41) for control of the program run of the CPU; if not, to take programming operating data directly from the ROM (40). The programming stored in the auxiliary EPROM (41) may direct the CPU (30) to carry out programming steps stored in the main ROM (40) in the stored sequence, or in changed sequences, as well as to take operating steps directly from the auxiliary EPROM (41). All programming data are stored in the auxiliary EPROM (41) also in modular or block form, and preferably include diagnostic programs relating to monitoring a function of the vehicle or of the engine, under control of data computed by the CPU (30).
