摘要： A control apparatus for an internal combustion engine is provided that can precisely reflect requirements relating to performance of the internal combustion engine in a control amount of each actuator by compensating for weaknesses in the so-called torque demand control. A requirement value of each of torque, efficiency, and an air-fuel ratio, and engine information are inputted to an engine inverse model.

An actuator direct requirement value directly required of each of actuators is also acquired. Control of the actuators is adapted to be changed between that according to the actuator requirement value and that according to the actuator direct requirement value.

摘要： A fuel injection timing control device for an internal combustion engine. The device comprises a fuel injector for injecting fuel into the intake port of an engine cylinder and an fuel injection end-timing control system for controlling the fuel injection end-timing of the fuel injector so as to advance gradually, from a first crank angle in the intake stroke to a second crank angle before the intake stroke, according to the engine operating condition. Accordingly, when the fuel injection timing is changed, the amount of fuel which sticks or adheres in the intake port is gradually increased by a small amount, at each fuel injection, so that the air-fuel ratio of the mixture does not become so lean the drivability of the vehicle is deteriorated.

摘要： This invention is intended to ensure that a control device for a vehicle drive unit is capable of realizing desired torque by making the main-actuator and sub-actuator collaborate adequately while holding the interposition of the sub-actuator as low as possible. For this end, a future target of torque that is going to be output from the engine and a realization timing of the future target are taken as reservation information for reserving engine torque regulation. Next, the required period, which is required to realize the future target when a main-actuator (a throttle) is operated to regulate the torque, is computed from a current engine operating condition. Then, the operation of the main-actuator is started at the timing preceding the realization timing by the required period for realizing the future target. In parallel with that, a sub-actuator (an ignition system) is operated to cancel out a torque change induced by the operation of the main-actuator during the period from the start timing of the operation of the main-actuator to the realization timing.

摘要： When fuel cut permission conditions are satisfied, a guard provided by an ignition timing retardation limit is relieved. In the resulting state, the ignition timing is retarded to decrease the output torque of an internal combustion engine. After the output torque of the internal combustion engine is decreased to a predetermined minimum torque, the supply of fuel is shut off. When, on the other hand, recovery from a fuel cut is to be achieved, the guard provided by the ignition timing retardation limit is relieved until completion conditions for recovery from the fuel cut are satisfied. In the resulting state, the ignition timing is retarded to decrease the output torque of the internal combustion engine.
