Abstract: PURPOSE: A method for confirming heaps of carbon for vehicles is provided to solve an ignition-off phenomenon due to carbon heaps in a throttle body of an ETS system by utilizing a carbon heap index. CONSTITUTION: A calculated value of an R.P.M is obtained by subtracting a real R.P.M from a target R.P.M(110). Then, it is determined whether the calculated value is larger than a reference value of the calculated value(120). If the calculated value is larger than a reference value of the calculated value, a long time learning value is calculated(210). Then, it is determined whether or not the long time learning value is identical to a total value of the long time learning value and a direction limit value(230). If the long time learning value is different from the total value of the long time learning value and the direction limit value, a time counter is reset to zero(150). If an engine is in an ignition-off state, the checking process is finished.

Abstract: PURPOSE: A method for controlling a throttle valve of a vehicle engine is provided to achieve a constant vehicle acceleration depending an acceleration pedal actuating degree by varying a method of controlling an opening degree of the throttle valve. CONSTITUTION: When an engine is in an ignition-on state(S100), it is determined that a filtering condition is satisfied(S110). If the filtering condition is satisfied, time change is counted and first and second filtering coefficients are calculated(S120). Then, the amount of intake air is calculated. At this time, the first and second filtering coefficients used for calculating the amount of intake air are differently applied depending on the variation of time. After that, a throttle valve opening degree correcting value is calculated, thereby outputting a throttle valve opening control signal.
