Abstract: PURPOSE: A control method for the fuel injection amount is provided to prevent a vehicle from abnormally traveling by controlling fuel injection amount while the trouble of an acceleration pedal cable occurs. CONSTITUTION: To control the fuel injection amount of an electronic control fuel injection system based on intake air amount, first, a control system detects the increase rate of an engine RPM for a specific time. When the increase rate is more than a specific value, fuel amount injected to an intake manifold is reduced. Then, the control system detects the opening degree change rate of a throttle valve and the opening degree change rate is kept in 'zero' for a specific time. In case that the opening degree of the throttle valve is not a maximum value or a minimal value, fuel amount injected to the intake manifold is reduced. With the increase rate of the engine RPM and the opening degree change rate of the throttle valve, the trouble of the throttle valve is detected and the fuel injection amount is adjusted. Therefore, the control system prevents the abnormal travel of a vehicle such as a sudden start or a non-returnable acceleration pedal without an additional device.
