摘要： In a method and a system for engine control an engine control signal is generated on the basis of a signal produced at each moment from at least one sensor for detecting the operating condition of the engine, the control signal being used for engine control. In order to attain the proper engine operating condition, data representative of the detection signal from the sensor is adjusted in advance, and data for correcting the sensor output is calculated from said adjustment value, the correction data being stored in a memory. While the engine is running, the data representative of the detection signal from the sensor is corrected by the correction data stored in the memory, and this corrected detection signal representative data is used to produce the control signal.

摘要： A control apparatus for an internal combustion engine is arranged such that, for each of the operating condition sections (A, B, C) of an internal combustion engine (1), a deviation (K.sub.l) of a feedback control value in the section from a reference value is detected and written in a region in a memory corresponding to the section in the form of a map, and the deviation (K.sub.l) is read out such as to be used as a correction value when control is effected in relation to the corresponding operating condition section. In such control apparatus, whether or not the number of regions in the memory into which deviation values for operating condition sections (T.sub.p, N) have already been written has reached a predetermined value is examined. When the number has reached the predetermined value, a deviation value is written into each of the regions in the memory into which no deviation values have yet been written, this deviation value already being stored in the adjacent region in the memory in which writing of deviation data has already been completed, whereby the feedback control delay can be eliminated.

摘要： The object of this invention is to reduce shift shocks by controlling the driving torque during gear shift changing so that the driving torque is represented by a smooth, ideal waveform.The driving torque calculating means estimates the output shaft torque of the automatic transmission from the engine torque characteristic or torque converter characteristic and, based on the estimated driving torque, generate a targeted torque pattern during gear shift changing. The engine torque control value calculating means calculates the control value for controlling the engine output torque, i.e., an ignition timing correction value .DELTA..theta.ig, so as to eliminate the deviation between the targeted torque and the driving torque estimated by the driving torque calculating means. This ignition timing correction approximates the driving torque to the smooth targeted torque. This configuration realizes the object mentioned above.

摘要： An estimating execution for an inner surface portion adhesion fuel amount is practiced distinctlly and independently to an execution processing for a basic fuel injection amount. A correction coefficient to be multiplied by the basic fuel injection amount is calculated in accordance with the estimation execution for the inner wall surface portion adhesion fuel amount. The correction coefficient is multiplied by the basic fuel injection amount. Since the fuel injection amount is corrected in accordance with the estimated inner surface portion adhesion fuel amount, an air-fuel ratio during a transitional period of an engine can be maintained at a desirable value.
