摘要： In a case where an internal combustion engine is executing an all-cylinder operation to operate all cylinders, an air-fuel ratio estimation part of an ECU 1 estimates an air-fuel ratio of each of the cylinders by using a first observer. On the other hand, in a case where the internal combustion engine is executing a cylinder-cut operation to rest a part of the cylinders and to operate other of the cylinders, the air-fuel ratio estimation part does not estimate the air-fuel ratio of each of the cylinders by using the first observer.

摘要： A control value calculation part includes an in-cylinder state estimation part that estimates a state to which the cylinder belongs between a plurality of PM-PN generation states. The plurality of PM-PN generation states are states in which a particulate matter is easily generated as compared with the other state, and are different from each other in a cause to generate the particulate matter. Further, in a case where it is determined that an operation state of an engine is a PM-PN exhaust state, the control value calculation part calculates a control value of an actuator in such a way to eliminate the PM-PN generation state according to the PM-PN generation state to which the state in the cylinder belongs.

摘要： An abnormality diagnosis device introduces a pressure into a reference-pressure detecting portion by utilizing a pressure introducing portion to detect a reference pressure correlative to a reference orifice, detects a purge-valve closed pressure that is a pressure in an evaporation system of when a pressure is introduced into the evaporation system by the pressure introducing portion after the purge valve is controlled to be closed, and detects a purge-valve open pressure that is a pressure in the evaporation system of when a pressure is introduced into the evaporation system by the pressure introducing portion after the purge valve is controlled to be open. The abnormality diagnosis device determines whether a leakage abnormality of the evaporation system and a fixed open abnormality are generated, based on a magnitude relation between the reference pressure, the purge-valve closed pressure, and the purge-valve open pressure.

摘要： A hybrid vehicle having a power-transferable combination of an engine and a motor-generator is controlled to prevent a vehicle vibration while preventing an over-revolution of the engine when the engine is started. In such control, while the engine is determined to be in a starting state, an instruction value correction is performed for correcting a per-unit-time change amount of an actuator instruction value, such as a target air intake amount and/or a target air load amount, according to a target output of the engine so that a steep increase of the engine revolution speed is prevented. With such a correction of the instruction value, an air intake amount of the engine and the engine revolution speed is gradually increased, thereby preventing the over-revolution of the engine and a steep increase of a load torque of the motor-generator, which prevents vehicle vibration when the engine is started.
