    摘要: A switching circuit is suggested for controlling the current through an electrical consumer, in particular an electromagnetic consumer (10), whereby a field effect transistor (11) is used as a control and current measuring member being series connected to the consumer. The field effect transistor is brought into the conductive condition with the assistance of a controlling device, such as an operational amplifier which in turn is immediately controlled by switching-on enforcing means when the field effect transistor is short-circuited with respect to a power source. The switching-on enforcing means comprise a capacitor, for example.

    摘要: To provide control of a vehicle engine computer from a segmental disk transducer by indicating a specific marker angular position of the crankshaft, to, characterize a specific cylinder in a multi-cylinder engine, the disk (1) has uniformly spaced segments (10, 20, 30, 40) thereon, the number of segments corresponding to the number of cylinders; one of the segments is foreshortened, so that the passage of the leading flank (11) thereof past a stationary pick-up transducer (2) will occur at a time later than that of the leading edges or flanks (21, 31, 41) of the remaining segments. The trailing flanks (12, 22, 32, 42) of all the segments are identical, and signals derived by processing the trailing flanks can be used to obtain speed signals; by processing the leading flanks, interrupt signals are applied to an interrupt input (3f) of a vehicle computer (3) to initiate a subroutine or subprogram. Additionally, a clock is started which, by counting, stores a representation of the circumferential length of the largest one of the segments. The length representation, as stored, is compared with a subsequent count in a comparator (9) and, if the counts do not match, this indicates that the then-appearing segment before the pick-up is the one which is foreshortened. The counter is reset upon sensing each trailing flank, and the memory, likewise, is reset each time a new count is entered thereinto.

    摘要: A pressure sensor is disposed downstream of a throttle valve in the intake tube of an internal combustion engine. When the throttle valve is closed, a throttle valve switch generates a logic signal. A monitoring of the pressure sensor is effected in that upon the simultaneous occurrence of the logic signal and a pressure signal which corresponds to an abnormal or a physically impossible state when the throttle valve is closed, an alarm is triggered.
