摘要： An engine output for bringing the drive power of a motor vehicle to a requested value is determined as a target output. One of the lean burn and the stoichiometric burn is selected as a combustion form that achieves a best fuel consumption performance in terms of the control of the actual engine output to the target output. That is, an output value that serves as a criterion for determining whether to switch the combustion force is determined based on the minimum fuel consumption rate during the stoichiometric-burn operation and the minimum fuel consumption rate during the lean-burn operation in which the fuel consumption involved in the rich spike control is taken into account. If the target output is less than the output value, the lean-burn operation is performed. If the target output is greater than the output value, the stoichiometric-burn operation is performed.

摘要： A fuel supply amount control apparatus for an internal combustion engine uses an idling control amount QISC obtained by reducing an idling control amount Qa by an idling control amount correction value KQISC, when determining the amount of fuel injected for the lean combustion when the vehicle is running. Therefore, during the lean combustion with the D range is selected, there is substantially no difference between the road load amount of fuel injected during the idling state and the road load amount of fuel injected during a low-speed running of the vehicle. Hence, an increase in the amount of fuel injection during the low-speed running of the vehicle based on the lean combustion achieved upon a fuel increase request does not result in an excessively great output torque of the engine, so that the low-speed running of the vehicle becomes stable and good drivability can be maintained.

摘要： A target driving force is calculated by an ECU on the basis of an accelerator opening and a vehicle speed, and a rounded target driving force value (or a corrected target driving force), as gradually changed from the driving force, is determined in the course to reach the target driving force. On the other hand, a rounded target power value (or a corrected target power) is determined on the basis of the rounded target driving force value. Moreover, the gear ratio of a CVT is controlled according to a target power calculated on the basis of the target driving force, and the load on an engine is controlled on the basis of the rounded target power value, so that the reduction in the power characteristics or the physical discomfort, as might otherwise be caused by the difference in the response between the engine and the CVT, is loosened.

摘要： A vehicle drive power control apparatus and method control the speed ratio of a transmission based on a speed shift line that is set so that, within a practical region, the speed shift line is in a low revolution speed side of an optimal fuel consumption line determined based on the efficiency of the engine and the efficiency of the transmission. Therefore, the width of increase in revolution speed from the speed occurring at the beginning of the practical region is curbed. Hence, the fuel consumption resulting from inertia torques caused by fluctuations in engine revolution speed, that is, fluctuations in the revolution speed of the input shaft of the transmission and a fluidic power transfer mechanism, is reduced, so that the efficiency as a whole increases and the fuel economy improves in comparison with the case where the optimal fuel consumption line is used as a control basis.

摘要： Abrupt deceleration of a vehicle is detected based on a depression amount or a depression speed of a brake pedal. If abrupt deceleration of the vehicle has been detected during fuel-cut control, a command is issued to make forcible restoration of control out of the fuel-cut control. Then a lock-up clutch is disconnected and fuel injection for an engine is resumed so as to restore a rotational speed of the engine. As a result, the engine is prevented from stalling due to the undershooting of the engine rotational speed.

摘要： Based on results of a knock control for adjusting ignition timing in accordance with the occurrence of knocking, an electronic control unit computes deposit required ignition timing akgrg, which is ignition timing determined by taking adhesion of deposits in an internal combustion engine into consideration. Based on the deposit required ignition timing akgrg, the electronic control unit reduces a vvt allowable variable range of a target VVT advancement amount, which is a control target value of a variable valve timing mechanism. The electronic control unit corrects a required ignition timing based on the actual VVT advancement amount vt, which is chanted according to the reduction of the allowable variable range of the target VVT advancement amount. As a result, problems resulting from the adhesion of deposits are effectively avoided.

摘要： An upper limit guard is set for a valve overlap amount according to a KCS learning value used to retard-correct an ignition timing in order to suppress knock, and an engine load. As a result, it is possible to make the upper limit guard value a value able to restrict the valve overlap amount to a value equal to, or less than, a value at which an internal EGR amount does not become excessive during a retard-correction of the ignition timing. By applying the upper limit guard to the valve overlap amount using the upper limit guard value, it is possible to suppress the valve overlap amount from increasing from the optimum value following a retard-correction of the ignition timing, as well as suppress the value of overlap amount from being reduced when it is not deviating from the optimum value and is below the upper limit guard value.
