    摘要: A method and an apparatus for detecting knocking combustion in an internal combustion engine, by evaluating the ionic current signal sensed in the combustion chamber, is especially adapted to correct or compensate the ionic current signal for longterm variations arising therein, for example due to variations in the composition of the fuel as a result of contamination with metallic components or the like. Thereby, erroneous knock recognition is prevented. To achieve this, a frequency-filtered time-sampled knocking component integral of the ionic current signal generated in the present combustion cycle is multiplied by a correction value determined from at least one integral value of the ionic current signal generated during at least one prior combustion cycle. The correction value is preferably a time-weighted combination of plural difference values that are respectively determined by subtracting an average integrated value of the ionic current signal from the knocking component integral of the ionic current signal in plural prior combustion cycles, and that are stored in successive positions of a shift register. If the final corrected knocking component integral falls outside of an allowable range, a knock recognition signal is released.

    摘要: A process for recognizing ignition failures in an internal-combustion engine which has two spark plugs per cylinder, based on a measurement of the ionic current at the spark plugs. In this process, the ionic current signals of the two spark plugs are each integrated using an assigned integrator over an entire combustion cycle and the integrator values are compared with one another. Since, in the case of a defective spark plug, an ionic current signal will occur only some time after the ignition (specifically after the arrival of the flame from the ignited spark plug), its integration value is significantly lower than that of the intact spark plug. From this information, the correct operation of the spark plugs is determined.

    摘要: A safety system for a motor vehicle having an internal-combustion engine. Independent quantities are used for the engine control and for the monitoring of the engine control. Control of the internal-combustion engine is performed, for example, by way of an operating parameter characterizing the engine load. Preferably, monitoring of the engine control is integrated into a traction control system, in which case the desired value for a quantity characterizing the vehicle propulsion, such as the output torque, is transmitted by the engine control to the monitoring system, while the actual output torque is determined in the traction control system from the rotational wheel speed. If a fault is recognized in the traction control system during the continuous comparison of desired values and actual values, a signal is transmitted back to the engine control unit, to influence the engine control.

    摘要: A method for determining the ignition angle for an internal combustion engine with adaptive knocking control, in which the occurrence of knocking is reduced by a controlled adjustment of the ignition angle in the retarded direction. The current values for the adjustment in the retarded direction are stored in a characteristic diagram in an operating parameter-dependent fashion. An average adjustment in the retarded direction is determined from these characteristic diagram values, and both a correction ignition angle and a control range limitation for the knocking control are determined therefrom. The fuel quality and ambient influences are automatically sensed with reference to a learned RON level and are also used to reduce the amount of energy expended to control engine knocking.

    摘要: The invention relates to a safety system for a motor vehicle having an internal-combustion engine. Independent quantities are used for the engine control and for the monitoring of the engine control. The control of the internal-combustion engine takes place by way of an operating parameter indicative of the operating condition of the internal-combustion engine--such as the engine load. In contrast, the monitoring of the engine control takes place by means of a quantity indicative of vehicle propulsion, such as the vehicle output torque, which is determined on the basis of a rotational wheel speed. The desired values for the engine control and for the monitoring are determined from the accelerator pedal position. The detection of the corresponding actual values is based on independent input quantities.
