摘要： A method for feedback controlling air-fuel ratio of the mixture supplied to an internal combustion engine having a plurality of cylinders comprises the steps of, detecting respective air-fuel ratios of the exhaust gas from the respective cylinders with an air-fuel ratio sensor having a substantially linear output characteristic; calculating an average air-fuel ratio by using the latest detected air-fuel ratios of the respective cylinders; determining a fundamental feedback correction coefficient .beta..sub.0 for a cylinder of which air fuel ratio is feedback controlled next; retrieving a learning correction coefficient .beta..sub.1 for the cylinder of which air-fuel ratio is feedback controlled next from a learning map prepared by learning for the corresponding cylinder; and determining new learning correction coefficients .beta..sub.1 for the respective cylinders using respective deviations of the respective detected current air-fuel ratios from the latest average air-fuel ratio calculated in the previous step, whereby air-fuel ratio control at any desired air-fuel ratio is carried out with a high accuracy and with a uniform air-fuel ratio throughout the whole cylinders.

摘要： A torque detection mechanism can be provided for a power train and its control unit without newly adding a sensor and its signal processing module. As a gear pair for the torque detection mechanism of a phase difference type, existing gears in a transmission are used, or a gear pair for this mechanism are provided adjacent to these existing gears. From phase signals sent from pickups, a phase difference signal is obtained by use of one part of existing devices in the control unit. The torque detection mechanism can be realized with the minimum number of component parts by utilizing the existing members and spaces instead of newly adding a sensor and its module. The invention can be applied to either of FF and FR cars, and has a practical structure in respect of the performance, costs and reliability.

摘要： An engine control apparatus for shifting an ignition timing signal to an ignition coil (48) so that the engine produces optimum torque generates a pseudo random signal (26) which is preferably an M series signal and applies the pseudo random signal to a parameter of the engine having a noise frequency component such as the engine rotational speed y(t). The M series signal is a signal having a impulse type self correlation function. A mutual correlation function of the number of revolutions of the internal combustion engine and of the M series signal is computed (30-44) and an optimum ignition advance angle is supplied to an adder (46). The adder (46) combines the optimized signal ignition advance angle with a basic ignition timing signal (.theta..sub.advB) to provide an ignition timing signal (.theta.ig) to the ignition coil (48).

摘要： A total control system for an automotive vehicle assures vehicular behavior precisely following to a driver's demand for variation of driving environment and provide smooth transition in variation of the driving environment. The system includes a driving environment index predicting section predicting vehicular driving environment on the basis of a driving operation indicative amount, such as an accelerator depression magnitude, a brake depression magnitude, a steering angular position and so forth and a vehicular condition indicative amount, such as an engine speed, a vehicle speed, a longitudinal acceleration and so forth. Based on the driving environment index derived by the predicting section, local control channels of the automotive vehicle are controlled. The driving environment index predicting section predicts the driving environment index by neural network or so forth to transfer to the local control channels though a vehicular local area network or a common memory. Accordingly, variable control corresponding to the driving environment in the local control channels can be realized.

摘要： In order to prevent a catalyst for an internal combustion engine from decreasing efficiency by deterioration after long time use of the catalyst, the decreased efficiency of the catalyst is determined, and the internal engine is controlled based on results of the determination so as to maintain high efficiency of the catalyst. The catalyst is installed in an exhaust pipe of the engine. Sensors for detecting conditions of exhaust gas both at upstream side and downstream side of the catalyst are provided, respectively. As for the sensor, for example, an oxygen sensor of which output varies stepwise at λ=1, or a sensor of which output varies in proportion to air-fuel ratio can be used. Detected values of the sensors are taken into a control unit, eliminating efficiency and deteriorating degree of the catalyst are estimated by comparison of the detected values, and the engine is controlled so that the eliminating efficiency becomes maximum. In accordance with the present invention, a preferable exhaust gas cleaning characteristics of the catalyst can be maintained because the decreased efficiency of the catalyst is determined exactly and the engine is controlled so as to prevent the catalyst from decreasing efficiency.
