    摘要: A control system for an automatic transmission, which can easily achieve a variety of shift patterns according to the taste of a driver and the situations of a running road. The control system comprises: a neural network; and a mode switch means for switching a teaching mode and an automatic mode. The neural network learns in the teaching mode and neuro-computes to output a gear ratio in the automatic mode. Further comprised are: tolerance error compute means for computing a tolerance error on the basis of at least one of th propriety of a teaching gear ratio, the ambiguity of an input value and the ambiguity of the teaching gear ratio; pattern produce means for producing a learning pattern; and combined load correct means for correcting the coupled loads of the neural network on the basis of the pattern produce means.

    摘要: A control device for an automobile has at least one sensor (8) for detecting an operational state of the automobile. An output from the sensor is applied to a sample and hold circuit (11) which is adapted to provide a time displaced output to a hierarchical group of neural elements (13). The neural elements operate upon said time displaced signals by varying the weighting of the signals and/or threshold values of the neural elements in accordance with a desired output parameter. The output of the neural computer is applied to a control circuit (2) which is adapted to control an automobile actuator. The hierarchical group of neural elements are provided with numerous forms of different learning functions so that the desired output parameter is achieved. In one such embodiment (Figure 32) desired parameters are applied to said neural computer and to a comparator, signals derived from sensors associated with automobile actuators are also applied to said comparator whereby difference signals are outputted from said comparator to control the weighting and/or threshold levels of the neural elements. The invention may be applied to different functions such as controlling air/fuel ratio, ignition timing, knock control, O₂ sensing, suspension adjustment, and road surface detection.
