    摘要： An object of the invention is to provide a vehicle control apparatus which can achieve a smooth start without generating any engine stall even if general drivers perform a rough starting operation in an MT vehicle, and can execute an engine torque operation having no sense of discomfort with respect to an accelerator operation. A rotating speed drop of an engine generated together with a clutch connection is detected so as to be set to a trigger of a control start, an engine rotating speed at a time of issuing the trigger is set to a target rotating speed, and a rotating speed feedback control having an engine torque as an operation amount is carried out. As an operating means for the engine torque, an ignition retard and a fuel cut are employed in addition to an intake air amount operation by an electronically controlled throttle. It is possible to achieve a just enough torque assist for minimizing a drop of the engine rotating speed at a time of connecting the clutch, by applying the rotating speed feedback control.

    摘要： A basic fuel injection pulse width value indicating an individual performance of an injector and an intake air flow amount value indicating an individual performance of an air flow sensor are prepared so as to memorize in plural memory areas in a store table, respectively. Deviations due to the basic fuel injection pulse width and deviations due to the intake air flow amount are memorized in the memory areas as learning values for controlling an air-fuel ratio, respectively. A corrected fuel injection pulse width is requested under the memorized learning values. An estimation learning is carried out at a first time learning. A first time learning value of the basic fuel injection pulse width is memorized in a whole area of the store table, and a first time learning value of the intake air flow amount is memorized in a corresponding area of the store table. By carrying out the learning on the air-fuel ratio control in accordance the estimation learning, the learning value absorbs the individual performance dispersion of the injector and the air flow sensor.
