    Abstract: A method for controlling engine revolutions of an automatic transmission in a vehicle is provided to improve the stability of engine idle by minimizing rapid fluctuation of the engine revolutions. It is determined whether a signal of an inhibitor switch is a swift shift state which is a fast shift manipulating state of D->N->R or D->N->R or not. If it is determined as the swift shift state, it is determined whether air-mass compensation control is started or not based on current RPM of a turbine. If the air-mass compensation control is required, a compensation amount is calculated based on the current RPM, and then a throttle position is controlled during a certain time according to the calculated compensation amount.

    Abstract: PURPOSE: A method for determining a start of an air/fuel ratio feedback control is provided to improve an idle stability and to prevent a fuel consumption ratio from being deteriorated by injecting fuel based on a reference map. CONSTITUTION: Output voltage data of an oxygen sensor and a throttle position sensor are checked(110,120). After 15 minutes lapses, it is determined whether or not output voltage of the oxygen sensor crosscuts 0.45V(130). If output voltage of the oxygen sensor crosscuts 0.45V, it is determined that the oxygen sensor is activated(140). Then, it is determined whether or not output voltage of the oxygen sensor exceeds 0.45V(150). If output voltage of the oxygen sensor exceeds 0.45V, it is determined that an amount of fuel is rich(160). After reducing the amount of fuel through a feedback control, it is determined whether or not an engine is in an ignition-off state(180).

    Abstract: PURPOSE: A method for correcting for an air flow is provided to reduce an exhaust gas flow and to improve stability of an idle state of a vehicle by correcting the air flow. CONSTITUTION: An idle state is maintained and a temperature of cooling water in an engine is checked(S210). Then, an air flow required for P and R ranges of an automatic transmission is checked in real time(S220). After that, it is determined whether or not a gear-shift is carried out from P to R ranges(S230). Then, an R.P.M of a turbine is checked(S240). It is determined whether or not an R.P.M variation of the turbine is larger than a predetermined value(S250). If the R.P.M variation of the turbine is larger than the predetermined value, a correcting value of air according to a temperature of cooling water is corrected to a gain according to a temperature of cooling water. Then, the air flow is reduced until the compensating value of air reaches zero(S260).

    Abstract: PURPOSE: A target angular control method for an electronic throttle system of an engine is provided to improve fuel consumption ratio and to prevent exhaust from being generated by preventing dual acceleration and acceleration delay when a vehicle is traveled. CONSTITUTION: When power is applied to a vehicle, all parameters are initialized(S100). Then, it is determined whether the vehicle is in an acceleration mode. If the vehicle is in the acceleration mode, a variation of an angular degree of an accelerator pedal is corrected by applying first and second tailing coefficient. A final target angular degree of an engine throttle is calculated based on the variation of the angular degree of the accelerator pedal and a variation of an idle speed actuator(S140). After that, an electronic throttle driving control signal is generated based on the calculated final target angular degree of the engine throttle.
