摘要： An air conditioning device for vehicle includes a refrigeration cycle including a compressor for sucking, compressing and discharging a refrigerant, a condenser for condensing the high-temperature and high-pressure refrigerant discharged from the compressor, an expansion valve for decompressing the refrigerant condensed in the condenser and an evaporator for evaporating the refrigerant through heat exchange between the refrigerant reduced in pressure by the expansion valve and surrounding air. This air conditioning device for vehicle increases an operation rate of the compressor more than that before a vehicle speed drops below a first permitted vehicle speed higher than a fuel cut recovery vehicle speed when an air conditioner is on, at which the compressor is actuated, when the vehicle speed drops below the first permitted vehicle speed during the deceleration of a vehicle associated with a fuel cut.

摘要： In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. The engine is started in response to a request to restart the engine while an engine speed is decreasing due to an automatic stoppage by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, and by using an electric motor if the engine speed is less than the combustion recoverable rotational speed threshold. When the engine speed of the internal combustion engine falls below the combustion recoverable rotational speed threshold while the engine speed is decreasing due to an automatic stoppage, an amount of air entering cylinders is reduced to be less than before the engine speed fell below the combustion recoverable rotational speed threshold.

摘要： In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, at which restarting is possible only by fuel injection. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started using a starter motor if the engine speed is less than the combustion recoverable rotational speed threshold. When there is a request to restart the engine in a brake ON state, the engine is not started by resuming fuel injection, but rotated and started using the starter motor.
