초록 ▼

The idling speed of an internal combustion engine is adjusted in accordance with the required performance of an evaporator of similar air cooler in a vehicular air conditioning system. Sensors monitor engine conditions pertinent to idling speed, including the air temperature at the output of the evaporator. If the evaporator is required to work at peak output, the idling peak is also increases to a maximum. As the load on the evaporator drops, so does the idling speed.

대표청구항 ▼

An idling speed control system for an automotive internal combustion engine associated with an air conditioning system, comprising: a cool air source in said air conditioning system, said cool air source being driven by said internal combustion engine for producing cool output air; an engine idling control means including an electrically operated actuator for adjusting an idling speed of the engine; a first sensor monitoring a basic engine idling control parameter and producing a first sensor signal indicative of the basic engine idling control parameter; a second sensor associated with said cool air source in said air conditioning system for monitoring the output air temperature of said cool air source and producing a second sensor signal indicative of the air cool source output temperature; and a controller deriving a basic engine idling speed based on said first sensor signal and deriving a basic control signal indicative of the basic engine idling speed, and said controller being responsive to an air conditioning mode selector for deriving a correction value for said basic engine idling speed based on said second sensor signal when air conditioning is selected on said air conditioning mode selector so as to adjust said output air temperature to a given value, which correction value varies with said second sensor signal value from a maximum value when air conditioning is initially selected on said mode selector through a decreasing range to a lower final value as said output air temperature of said cool air source decreases, and modifying said basic control signal by said correction value to derive a modified control signal for controlling said actuator so as to adjust the engine idling speed to a speed corresponding to the basic idling speed modified by said correction value.
