Abstract: PURPOSE: A method for reducing the rattle of an automobile is provided to quantitatively measure vibration by installing an acceleration sensor in a transmission case and control engine output based on the measurement. CONSTITUTION: If an engine is started, an automobile operation state detector receives changes in an automobile operation state for calculating an RPM(Revolutions Per Minute) angular velocity(S100,S110,S120). The automobile operation state detector transforms the RPM angular velocity and transmission case acceleration through FFT(Fast Fourier Transform)(S130). It is judged whether engine idle is normal(S140,S150). If so, it is judged whether the rattle of the transmission is generated(S160). If so, a deviation of an RPM is calculated to be compared with a set reference so that an ignition period is controlled(S170,S180).

Abstract: PURPOSE: An off-idle knock is expected beforehand to control fuel amount, thereby stabilizing engine combustion. CONSTITUTION: An engine fuel amount and rpm are detected by a throttle position sensor and a crank position sensor respectively. A voltage value of a throttle position sensing signal of the throttle position sensor is sensed, and rpm of engine is calculated by a crank position sensing signal from the crank position sensor. An off-idle knock is decided if the voltage value of the throttle position sensing signal increases abruptly over a set value and the engine rpm is reduced abruptly compared to an idle rpm. If the off-idle knock is decided, the fuel amount supplied to the engine is increased by a certain value.
