Abstract

When a vehicle power demand P* is less than a threshold value Pref, which is set to or around a lower limit of a relatively efficient drive range of an engine (step S120) and when an engine drive demand EG* is set ON because of requirement for heating by an air conditioning system (step S150), the drive control of the invention sets the threshold value Pref to an engine power demand Pe* (step S160) and sets a higher level S2 than a standard level S1 to a maximum SOC (state of charge) of a battery (step S170). This drive control starts load operation of the engine with charge of the battery. The load operation of the engine desirably improves the fuel consumption of the vehicle, compared with independent operation of the engine.

Description

technical field [0001] The invention relates to a vehicle and a control method of the vehicle. Background technique [0002] There has been proposed a vehicle in which permission and prohibition of idling stop of the engine is set according to the outside air temperature and the air blowing temperature at an air outlet for heating arranged in the passenger compartment of the vehicle (see, for example, Japanese Patent Laid-Open Gazette No.2001-341515). This proposed vehicle prohibits idling stop of the engine when the outside air temperature is lower than a preset first temperature or when the air blown out temperature at the air outlet is lower than a preset second temperature. This prohibition ensures the exertion of sufficient heating performance of the air conditioning system installed on the vehicle. [0003] Prior art vehicles prohibit idle stop of the engine by the requirement to heat the passenger compartment with the air conditioning system to ensure sufficient hea...
