Abstract:
A vehicular internal combustion engine control apparatus comprising:engine automatic stop-startup means for automatically stopping the internal combustion engine if a state of operation of the internal combustion engine satisfies an automatic stop condition, and for automatically starting the internal combustion engine if the state of operation of the internal combustion engine satisfies an automatic startup condition; and engine automatic stop permission-prohibition means for permitting an automatic stop of the internal combustion engine if a temperature of a cooling medium of the internal combustion engine used as an air-conditioning heat source by a cabin air-conditioner is higher than a threshold value, and for prohibiting the automatic stop if the temperature of the cooling medium is lower than the threshold value, wherein the threshold value related to the engine automatic stop permission-prohibition means is variable in accordance with at least one of an inside-cabin temperature and values related to the inside-cabin temperature, and wherein a hysteresis width of the threshold value is set greater than a hysteresis width that is needed to prevent hunting in control.
