摘要： A central digital memory contains data relating values of operational variables of an installation to values of a stored parameter. The central memory is addressed in parallel via input lines carrying the address of the stored data. The address is generated by selecting one of several discrete input lines leading to an address selector memory which contains preliminary addresses related to the various operational states of the installation. A portion of the preliminary address is delivered directly to the central memory whereas another portion is used to preset a counter. If the particular operational state is dependent on another parameter, for example temperature, a temperature-dependent clocking frequency is admitted to the counter and alters its contents which are then used to supplement the first portion of the address already delivered to the central memory. If no temperature dependency exists, the second portion of the address is passed on without change.

摘要： Fluctuations of engine speed in the frequency range from 2 to 8 Hz, which produce "bucking" behavior of a motor vehicle, are detected by passing engine speed signals through a filter which reduces and delays the oscillations and a difference signal is then produced between the original and the processed speed signal in order to derive an alternating signal in the form of a square wave indicating the sign of a correction to be made to engine ignition timing for counteracting the bucking oscillations of engine speed. The square wave determines the sign of an anti-bucking ignition timing correction factor, of which the absolute value may be constant or may vary according to the sign of the correction and, if desired, also in accordance with engine operation parameters.

摘要： An electronic control system for internal combustion engines which has signal generator circuits for the fuel metering and for the ignition. During starting, especially in the case of cold starting, three different phases are provided for controlling the injected fuel quantity and for regulating the fuel quantity downward; furthermore, the ignition angle is adjusted in accordance with temperature and rpm. In terms of the fuel metering, the boundary between the first and second phase is dependent on the rpm or on a maximum total number of revolution cycles, and the end of the second phase is predetermined by a minimum metering signal which is dependent on temperature. In the ignition system, there is an increasing adjustment toward "early" approximately in the rpm range between 200 and 600 revolutions per minute as well as an increasing adjustment toward "late" as the temperature increases.

摘要： The air flow rate and the speed of an internal combustion engine are sensed and translated into pulse trains of variable frequency. During a time interval defined by the rpm related signal, a digital counter receives and counts the air flow rate frequency. Subsequently, the contents of this counter are counted out by a pulse train whose frequency is adjustable depending on other engine conditions such as start-up, warm-up, idling, full-load and the like. The apparatus also includes circuitry for generating a control pulse of minimun length.

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： An apparatus including a computer for generating a time duration signal is proposed, intended in particular for controlling fuel metering or ignition processes in internal combustion engines, wherein the time duration signal is formed in accordance with the formulati=(R+K.multidot.Z)/fclwhere Z is the counting range of a counter associated with the computer, k is the number of counting processes, fcl is the counting frequency and R is a remainder value. In accordance with the above formula, the counter first counts downward from this remainder value R and then, for a desired number k of counting processes, runs through the total counting range. In the case of an 8-bit counter, for instance, this counting range value is 256.

摘要： To reduce the data processing requirements within operating cycles of an automotive-type microprocessor or computer, the input/output unit has an angle increment counter receiving angle increment signals synchronized with rotation of the crankshaft of the engine, the counter providing output signals to comparators which, when the count state reaches predetermined values as applied from a data bus, derived from the microprocessor, to the comparator, then provides output signals to control the engine, for example by providing ignition control output signals, fuel injection control output signals, or the like. To further simplify computational tasks of the microprocessor, the input/output unit contains a timing element, for example a counter, which can provide variable timing intervals, for example by controlling the clock rate of the counter or a count number, under control of the data bus, and a transfer switch which selectively applies to a further counter either the signals from the timing circuit or from the crankshaft angle increment counter so that, as desired, data then being processed in the microprocessor can be selectively based on or compared with engine speed, or predetermined timing intervals, for consequential control of other operating parameters of the engine and the entire power train system of which it is a part.

摘要： To permit use of integrated circuits in solid-state ignition control systems in which the current through the primary of the ignition is pulsed when a predetermined level is reached, a threshold switch which has switching hysteresis is connected to control conduction of an auxiliary semiconductor connected in parallel with the ignition coil, to control the auxiliary semiconductor to become conductive when the current through the coil rises above a predetermined first threshold level to thereby shunt the primary thereof or to block the auxiliary semiconductor switch when the current through the coil drops below a predetermined second threshold level and thereby removes the shunt from the primary of the ignition coil and permits current flow from a power source thereto to ensure, reliably, alternate opening and closing of the main controlled switch, typically a transistor, in series with the coil and the auxiliary controlled switch.

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： A regulating device is proposed for a fuel metering system of an internal combustion engine having .lambda. regulation. The regulating device includes a P-I regulator, and the individual control variables of the regulator are stored in memory and are capable of being recalled in accordance with operating characteristics. By means of asymmetrical P and I components that is, different values at the transition from a lean to a rich mixture or vice versa, the average value for .lambda. can be shifted in a clearly-defined manner, so that the individual exhaust gas components are substantially adapted to the desired values at all operational points. The individual P and I components or regulator control variables are stored in memory in performance graphs, which preferably permit finely-distinguished regulator control during partial-load operation.
