摘要： A shift control system which can reduce a shift shock is provided. A target torque determiner set a target torque of an engine based on an accelerator position. An actual torque determiner calculates an actual torque of the engine in the inertia phase. A controller calculates an integrated value of a difference between the target torque and the actual torque from a commencement of the inertia phase to a predetermined time point before a termination of the inertia phase, and corrects the target torque in a remaining period between the predetermined time point and the termination of the inertia phase.

摘要： A control system for a vehicle that executes a feedback control properly to adjust a speed of a predetermined rotary member to a target speed. A controller is configured to: calculate an amount of change in a torque applied to the rotary member by one of the torque devices, in accordance with operating conditions of the torque devices; and calculate an amount of change in the torque applied to the rotary member by another one of the torque devices, based on a target amount of change in a synthesized torque of the torques of the torque devices and the amount of change in the torque applied to the rotary member by one of the torque devices.

摘要： To improve accuracy in misfire determination, a control apparatus for an internal combustion engine that controls an internal combustion engine having a variable compression ratio mechanism capable of changing the compression ratio of the internal combustion engine includes a controller configured to: determine that a misfire occurs if the magnitude of rotational fluctuation of the internal combustion engine is equal to or larger than a misfire criterion value and to make the misfire criterion value larger during the time in which changing of the compression ratio of the internal combustion engine is in progress than during the time in which the compression ratio is not being changed.

摘要： In a multiple cylinder supercharged engine, when reduced cylinder operation is executed, a throttle, which is located downstream of a compressor driven by a turbine provided in an exhaust passage, through which exhaust gas of a cylinder group flows, is operated to a fully closed state, wherein the reduced cylinder operation is applied to the cylinder group. A fuel injection amount of at least one cylinder included in the cylinder group is made smaller than a fuel injection amount of a cylinder included in another cylinder group, and this at least one cylinder is operated, in order to increase rotational speed of the compressor, so that a value of pressure of an upstream side of the throttle is controlled to a value, which is equal to or larger than a value of pressure of a downstream side of the throttle.

摘要： A control system is applied to an internal combustion engine having a plurality of cylinders, a variable compression ratio changer configured to change the compression ratio of each of the cylinders of the internal combustion engine individually, in-cylinder injection valves that inject fuel into the respective cylinders, and in-passage injection valves each of which injects fuel into an intake passage corresponding to each of the cylinders. To reduce differences in the air-fuel ratio among the cylinders during changing the compression ratio, the control system makes the proportion of the quantity of fuel injected through the in-passage injection valves to the total quantity of fuel injected through the in-cylinder injection valves and the in-passage injection valves larger during the time in which the compression ratios of all the cylinders are being changed than during the time in which the compression ratios of all the cylinders are fixed.
