摘要： A control device for an internal combustion engine includes a throttle valve opening degree detector, an air bypass valve controller, and a torque reduction controller. The throttle valve opening degree detector detects an opening degree of a throttle valve which is provided downstream with respect to a compressor of a supercharger. The air bypass valve controller opens an air bypass valve based on a reduction change in the opening degree of the detected throttle valve. The air bypass valve is configured to open and close a bypass path. The torque reduction controller controls the throttle valve to reduce the opening degree of the throttle valve while an automatic transmission connected to the internal combustion engine is in an acceleration shifting in order to execute a torque reduction control. The air bypass valve controller maintains the air bypass valve in a close state during the torque reduction control.

摘要： A control device for a hybrid vehicle includes a push-start mode and a motor start mode. The push-start mode transmits a driving force from driving wheels to the engine via a first transmission route at a speed detected by a speed detection means equal to or more than a predetermined speed to start the engine. The motor start mode starts the engine using a driving force of the motor at a speed equal to or less than the predetermined speed as well as in a stopped state. At a speed outside a speed range that either mode is executable when a start command of the engine occurs in driving only using the electric motor as the driving source, a control means performs the driving force reduction control for reducing a driving force transmitted from the electric motor to the driving wheels of the vehicle.

摘要： A control apparatus for an internal combustion engine includes circuitry configured to control a fuel injector of the internal combustion engine to stop injecting fuel to reduce torque generated by the internal combustion engine during upshift. The circuitry is to acquire a target injection amount parameter corresponding to a target injection amount of the fuel to be injected by the fuel injector to operate the internal combustion engine based on an operation state parameter corresponding to an operation state of the internal combustion engine. The circuitry is to acquire a minimum injectable amount parameter corresponding to a minimum injectable amount of the fuel injectable from the fuel injector. The circuitry is to control the fuel injector to start injecting the fuel when the minimum injectable amount parameter exceeds the target injection amount parameter while the fuel injector is controlled to stop injecting the fuel during the upshift.

摘要： A control device of a vehicle capable of improving acceleration responsiveness and suppressing increase in the NOx emission amount when a required torque is increased during a steady lean operation. A target air-fuel ratio (AFCMD) is set according to an accelerator pedal operation of a driver. When the driver depresses an accelerator pedal to make an acceleration request during the lean operation, in which the AFCMD is set to a predetermined lean air-fuel ratio (AFLN), air-fuel ratio reduction control is executed to reduce the AFCMD according to the acceleration request. In the air-fuel ratio reduction control, when the AFCMD calculated according to a required torque (TRQCMD) is smaller than a limit air-fuel ratio (AFLMT), the AFCMD is set to the AFLMT, and the AFLMT is set to a value smaller than the AFLN set in a steady state of the lean operation and larger than a theoretical air-fuel ratio (AFST).
