Abstract: PURPOSE: A delay time control method for regulating the air amount of an automatic transmission is provided to prevent shift shock, and to stabilize engine RPM(Revolution Per Minute) by extending shift delay time with counting remaining time at P or N-range and R or D-range after starting. CONSTITUTION: Coolant temperature of an engine is detected according to information from a water temperature sensor by an ECU(Electronic Control Unit) in starting, and the target RPM and the target air amount are set based on coolant temperature. Stabilizing time of RPM fluctuation is checked according to each temperature. Shift delay time is compensated by counting remaining time at R or D and P or N-range after starting. The delay time for regulating the air amount is adjusted during stabilizing RPM fluctuation according to each temperature in shifting P into D or N into R-range.

Abstract: PURPOSE: A method for learning the fuel feedback gain for a vehicle is provided to prevent the sensibility of the exhaust gas from being degraded by learning and adjusting the fuel feedback gain even though an oxygen sensor is aged. CONSTITUTION: A method checks the rich condition or the lean condition by whether the present output of an oxygen sensor is more than a reference value when the RPM and load are in the aged determining region. If the run condition is checked, the previous output is checked whether it is the rich condition or run condition. If the lean condition is checked, the fuel feedback gain is adjusted with the conversion to the rich condition of the previous oxygen output by increasing the number of the rich/lean inversion in the oxygen sensor by one. If the rich condition is checked, the previous output is checked whether it is the rich condition or lean condition. If the lean condition is checked, the fuel feedback gain is adjusted with the conversion to the rich condition of the previous oxygen output by increasing the number of the rich/lean inversion in the oxygen sensor by one.

Abstract: PURPOSE: A measuring method of a moment of a rotating inertia for an engine is provided to contribute to studies about the moving characteristic, the power efficiency and the vibrating direction of the engine by measuring the moment of the rotating inertia. CONSTITUTION: An IMEP(Indicated Mean Effective Pressure) and a sum are detected through a piezoelectric sensor in a plug. A BMEP(Brake Mean Effective Pressure) is detected through a dynamometer. A correlation between the IMEP and the BMEP is set by calculating an inclination and a coefficient between the IMEP and the BMEP. A braking torque is calculated by calculating the sum of the IMEP in an idle status of an engine(10). A moment of a rotating inertia of the engine is calculated based on the calculated value and the inertia of the engine. The moments of the rotating inertia are compared and analyzed by accelerating the engine in the idle status based on the calculated moment and measuring the moment per RPM. Thereby, errors are reduced and the characteristic of the engine is found out easily.

Abstract: PURPOSE: A method for controlling idle revolution per minute is provided to prevent an undershoot of revolution per minute by determining whether an idle dash port control is stopped or not in comparison of an engine revolution per minute with a reference revolution per minute. CONSTITUTION: There is checked whether an idle dash port control is performed and then tailing for increasingly reducing an air amount of dash port is performed. Comparing an engine revolution per minute with a reference revolution per minute, if an engine revolution per minute is less than a reference revolution per minute, the tailing for the dash port is stopped. Comparing the dash port air amount with a hysteresis value according to the dash port control, if the hysteresis value is greater than the dash port air amount, the dash port tailing is stopped. On the contrary, if the dash port air amount is greater than the hysteresis value, the dash port tailing is continued. As soon as the dash port tailing is stopped, a feed back control of an idle air amount is started.

Abstract: PURPOSE: A method and an apparatus for compensating for an amount of air are provided to prevent the stall of engine by setting an initial value with an amount of air larger than long-studied value when a compressor of an air conditioner is repeatedly turned on/off. CONSTITUTION: An apparatus for compensating for an amount of air comprises a vehicle state detecting section(10), a control section(20), a memory section(30) and an actuator(40). The vehicle state detecting section(10) detects on/off of an air conditioner switch, on/off of a compressor, an RPM of an engine, and a position of a throttle valve. The control section(20) analyzes the signals detected from the vehicle state detecting section(10) and generates control signals so as to maintain an idle RPM for preventing the stall of the engine. The memory section(30) stores the number of on/off operation of the compressor. Reference data for compensating for an amount of intake air is stored in the memory section(30). The actuator(40) is driven based on the control signal of the control section(20).

Abstract: PURPOSE: An air amount compensation method is provided to satisfy a target idle rpm by starting a vehicle with an air amount compensation value before the complete explosion of fuel in hilly sections and generally supplying air after the complete explosion of fuel. CONSTITUTION: A method for compensating air amount comprises the steps of: starting an engine(20); deciding if a condition for the hilly sections is satisfied(21); deciding complete explosion(22); keeping a predetermined starting air amount compensation value before complete explosion(23); reducing a specific value from the predetermined starting air amount compensation value after complete explosion(24); deciding if a compensation reducing period initializing compensation air amount is lower than zero(25); reducing the compensation air amount to zero and outputting total air amount(26); and driving an engine with the total air amount and returning(27). Therefore, the starting of the engine on the hilly sections becomes smooth and the defective starting or stop of the engine after complete explosion is avoided.

Abstract: PURPOSE: A control method of start RPM(Revolutions Per Minute) and start time is provided to keep start RPM and start time regularly regardless of the engine starting of a vehicle. CONSTITUTION: A water temperature sensor measures the temperature of cooling water and outputs the value to an ECU(Engine Control Unit) when a driver starts an engine(S100,S110). The ECU decides whether the current maximum start RPM is higher than the maximum target start RPM corresponding to the temperature of cooling water or not. If the maximum start RPM is higher than the target value, the ECU receives decreasing start RPM through an engine RPM sensor. The ECU compares the start RPM with the sum of the target start RPM read out of a memory and an error range(S120). The ECU calculates the amount of air for starting by adding the learning amount of air to the former amount of air for starting if the start RPM is lower than the sum(S130). Otherwise, the ECU sets the amount of air by reducing the learning amount of air(S140). Finally, the calculated amount of air is saved in the memory of the ECU(S150). The amount of air for starting and a changing cycle of air are controlled whenever the driver starts the engine.
