摘要： In a dc electric fuel pump control apparatus for controlling the quantity of fuel supplied to a vehicle engine in accordance with an engine operating parameter condition such as an intake air flow condition or engine speed condition, when controlling a voltage applied to a fuel pump operating motor by closing or opening a fixed-resistor short-circuiting switch circuit in accordance with the magnitude of the operating parameter relative to a predetermined value, an increase or decrease of a battery power source voltage from a predetermined value is detected to increase or decrease the predetermined value of the engine operating parameter. Where a variable resistor is used in place of the fixed resistor, its resistance value in a low battery power source voltage condition is controlled lower than that in a high battery power source voltage condition.

摘要： A quantity of fuel supplied to an engine so as to allow the air-fuel ratio of a gas mixture to be a target air-fuel ratio is subjected to a feedback correction based on an air-fuel ratio sensor. At the time of the feedback correction, a learning correction is also conducted on the basis of a learning value that is calculated in accordance with a feedback correction value. When the learning value to be used for the learning correction is altered, the feedback correction value is initialized. An initialized feedback correction value is an addition of the feedback correction value before the alteration to a deviation of the respective learning values before and after the alteration of the learning values.

摘要： The control of a quantity of supply fuel to allow the air-fuel ratio of a gas mixture to be a target air-fuel ratio is conducted by switching between an open loop control and a feedback control using an air-fuel ratio sensor, in response to an operating state of the engine. At the time of the feedback control, a learning correction is carried out using a learning value calculated on the basis of the feedback correction value. At the time of the open loop control, the quantity of the supply fuel is corrected in accordance with the feedback correction value and the learning value immediately before shifting from the feedback control to the open loop control.
