    • The invention relates to a method and apparatus for controlling operating characteristic quantities of an internal combustion engine. For issuing an uncorrected anticipatory control value, a characteristic field is addressed by directing pregiven operating characteristic quantities as addresses and, with a simultaneously superposed control, an averaged value of the control factor is applied to the anticipatory control region for effecting an adaptive learning procedure. From the averaged control factor, a global factor is defined which works multiplicatively on the entire basic characteristic field. This considers especially multiplicative disturbance influences. Also, by means of a dividing of the self-adaptive characteristic field into a non-changeable basic characteristic field and into at least one further changeable factor characteristic field corresponding thereto, each basic value is multiplied within a pregiven influence region by means of the associated factor of the factor characteristic field whereby mostly additive disturbing influences are considered. Global factor and the particular factor from the factor characteristic field can conjointly work upon the control value issued by the basic characteristic field.
    • 本发明涉及一种用于控制内燃机的工作特性量的方法和装置。 为了发出未校正的预期控制值,通过将预先设定的工作特征量指定为地址来寻址特征字段,并且通过同时叠加的控制将控制因子的平均值应用于预期控制区域以实现自适应学习过程。 根据平均控制因子,定义了一个在整个基本特征领域中乘法运算的全局因子。 这特别考虑到乘法扰动的影响。 此外,通过将自适应特征场划分成不可改变的基本特征场,并将其与至少一个与之对应的其它可变因子特征场分开,通过相关联的每个基本值在预先设定的影响区域内相乘 考虑因素特征场因子,主要是加性扰动影响。 全局因子和因子特征领域的特殊因素可以结合基本特征领域发布的控制值。

    • The invention is directed to an apparatus and a method for controlling the operating characteristic quantities of an internal combustion engine, with a characteristic set up with operating quantities of the internal combustion engine for pre-control of engine variables influencing the operating characteristic quantities, and with a control arrangement, responsive to at least one engine variable, for correctively influencing the characteristic values. The values stored in the characteristic field and selected in dependence on operating characteristic quantities of the internal combustion engine are modified via the control arrangement to correctively influence the characteristic values. In addition, the characteristic values lying within the defined region of the characteristic value modified are also changed in dependence on the modification of this particular characteristic value. The fact that the modification of a characteristic region in dependence on the modification of its respective characteristic value is weighted, permits a rapid and accurate adaptation of the characteristic to the actual operating conditions of the internal combustion engine. The invention is advantageously suitable for use in various control systems contolling air-fuel metering, ignition point, charge-air pressure, exhaust-gas recirculation of idle speed, for example.

    • In a method and an apparatus for open-loop and closed-loop control of operating characteristic quantities of an internal combustion engine, it is proposed that the anticipatory or pilot control area, which is variable by means of learning, be embodied such that in a factor characteristic field associated with a basic characteristic field, not only the particular support point but with decreasing influence outward the area surrounding it as well are changed by the carry-over of an averaged regulating factor value. Alternatively, or preferably combined therewith, the factor characteristic field is replaced by at least two correcting characteristic fields, which have larger inclusion areas, overlapping one another, for each support point, so that even in the event of fluctuations of input quantities about a border of an area, at least one of the correcting characteristic fields will be addressed.

    • A method for training a neural network in order to optimize the structure of the neural network includes identifying and eliminating synapses that have no significant influence on the curve of the risk function. First and second sending neurons are selected that are connected to the same receiving neuron by respective first and second synapses. It is assumed that there is a correlation of response signals from the first and second sending neurons to the same receiving neuron. The first synapse is interrupted and a weight of the second synapse is adapted in its place. The output signals of the changed neural network are compared with the output signals of the unchanged neural network. If the comparison result does not exceed a predetermined level, the first synapse is eliminated, thereby simplifying the structure of the neural network.
