    摘要: In the case of a card cage for an electronic control unit having signal-processing analog and/or digital components, high-speed digital components, as well as components having both signal-processing functional parts, as well as high-speed digital functional parts and power components, which are arranged on a multilayer printed-circuit board and are electroconductively connected to a shared ground plane, the signal-processing components of each module having a shared connection to the common ground plane, the radiated interference from the control unit produced by high-frequency interference currents can be reduced, and high current densities in the ground plane and resultant potential shifts can be prevented from adversely affecting the signal processing, in that the signal-processing components are combined into signal-processing modules having at least one shared function, and the ground connections of all components of such a functional module are routed in each case via conductor connections to a common point of connection conductively connected over the shortest path to the shared ground plane, and the high-speed digital and power components are directly linked to the shared ground plane. By introducing an additional voltage-supply plane, the radiated interference from the control unit is able to be further reduced.

    摘要: In order to reduce the amount of ignition energy supplied to an ignition coil during low speed operation of the engine, an electronic circuit is provided to regulate the open time of the ignition circuit to be constant in an upper engine speed domain and to then obey a predetermined characteristic in the mid-range. The mid-range control is gradually made ineffective at lower engine speeds where the open ignition interval is determined by speed as measured by the duty cycle of the engine ignition transducer. The change of characteristics is obtained with the aid of a control voltage source which generates a speed dependent control voltage causing the discharge time of a capacitor to be extended at low engine speeds and causing the termination of the open time of the ignition to be determined by the transducer output signal.

    摘要: A transistor switch connected in series with the primary winding of the ignition coil permits and blocks current flow through the coil when in a conductive and non-conductive state respectively. Normally, the switch is "on" and "off" respectively in the presence and absence of an ignition current pulse furnished in synchronism with the rotation of the crankshaft of the engine. For increasing speeds, the time the switch is "on" prior to the ignition time is increased by switching it to the conductive state when the charge on a control capacitor reaches a predetermined charge. The charge on the control capacitor is changed in a first direction following receipt of each ignition signal. The rate of change of charge depends upon the resistance of the emitter-collector circuit of a first control transistor. The latter is, in turn, determined by the charge on an integrator capacitor which varies with changes in engine speed. When the charge on the control capacitor reaches a predetermined charge, the output transistor switch to the conductive state allowing current flow in the ignition coil.

    摘要: To reliably distinguish between knocking signals derived from an internal combustion engine knock sensor from all the other signals likewise derived from the knock sensor, which includes background noise signals, statistically distributed disturbance signals and the like, a correlation signal is generated, and the received signal is correlated with the correlation signal, which is cyclically varying at an average frequency which is of the frequency of the expected knocking signal, or a whole number multiple thereof. An output recognition is provided upon correlation between the correlation signal and the signal from the knocking sensor. The system can be implemented by a signal generator (6, 61, 62; 63) which provides the correlation signal, correlation being effected by an AND-gate (7, 71, 72; 73), or by software in a microprocessor in which an incoming knocking signal is interrogated in cadence with cyclical variation at the frequency which is the expected knocking frequency of the engine.

    摘要: The AC signal generator furnishing the basic control signal for ignition timing is a Hall generator the flux through which is gradually increased while the crankshaft of the engine rotates through a predetermined angle of rotation. The Hall generator is part of a magnetic circuit which also includes an air gap. The change in flux is accomplished by rotating a tapered magnetically conductive member through the air gap. The output of the Hall generator is applied through a linear amplifier to a threshold circuit whose output controls an electronic interrupter switch connected in series with the ignition coil.

    摘要: The safety device, especially in an electronic motor vehicle control system, protects external circuit branches supplied with current from an engine/motor vehicle control unit so that a single short circuit results in failure of only that circuit branch in which the short circuit is located, so that an emergency operation of the electronic motor vehicle control system is possible. The respective reference grounds of the external circuit branches are connected to a common ground conductor (11) via an interface (3) including respective reference ground connectors (d, k, m). Each reference ground connector includes a safety device in the form of thin wire plug bonds, whose maximum current load sets the maximum current load of the respective external circuit branches. Then, if there is a short circuit to the reference ground of the concerned external circuit branch to a main supply voltage, the remaining circuit branches remain unaffected and operational.

    摘要: The closure angle of an interrupter switch connected in series with the primary winding of an ignition coil is varied as a predetermined function of engine speed by charging and discharging of an integrator circuit which in turn changes the cut-in threshold of a threshold circuit controlling the operation of the interrupter switch. When the spark repetition rate becomes sufficiently high for residual energy to be stored in the coil when the interrupter switch closes, this type of control results in an undesired decrease of closure angle. Therefore, in the present system, the operation of the charging circuit for the integrator circuit is always delayed until the current through the primary winding reaches a predetermined minimum value exceeding the maximum possible residual current in the primary winding when the interrupter switch first closes. The charging circuit thus always operates from the same initial condition, preventing undesired changes in the closure angle at high speeds.

    摘要: A magnetically conducting flux-by-pass member shunts the main magnetic circuit, so that it no longer affects a Hall generator therein, while at the same time it completes an auxiliary magnetic circuit containing an auxiliary permanent magnet that causes magnetic flux to pass through the Hall generator in the opposite direction. The reversal of the magnetic flux in the Hall generator upon insertion and again upon removal of the flux-by-pass member increases the amplitude of the Hall generator signal and steepens the rise and fall of the signal.

    摘要: To operate an ignition control transistor, connected into the primary ignition coil under minimum saturation condition regardless of voltage level of the supply voltage, delivered, for example, from the battery of an automotive vehicle, at least one timing circuit is connected to the voltage supply to have a timing interval which varies as a function of supply voltage, the timing interval controlling the duration of current flow through the transistor as a function of supply voltage so that the transistor will be conductive for the required time to store magnetic energy in the coil, though not for an excessively long period of time regardless of the level of supply voltage within the limits normally experienced in automotive ignition systems.
