Abstract: 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.

The composite 5 comprises a transparent polymer 4 and a liquid crystal droplet 3. The liquid crystal droplet 3 is configured in a substantially hemispherical shape such that a bottom surface of the droplet is in contact with the alignment layer and the remaining surface excluding the bottom surface bulges towards an upper surface of the composite 5. The polymer 4 constitutes the other surface of the composite 5 such that the polymer 4 covers the hemispherical liquid crystal droplets 3. Thus, the invention achieves a liquid crystal display device in which one of the pair of substrates is eliminated and thereby the weight of the device is significantly reduced.

Abstract: 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.

Abstract: 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.

Abstract: 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.
