摘要： PROBLEM TO BE SOLVED: To suppress the deterioration of braking performance while suppressing the drive restriction of an auxiliary machine in the case of the shortage of brake negative pressure.
SOLUTION: A surplus amount B in consideration of the responsiveness of brake negative pressure recovery is added to a requirement value A for the brake negative pressure, and the shortage of brake negative pressure is determined by comparing the added value with the actual value of the brake negative pressure (S1). In the case of the shortage of the brake negative pressure, an ISC correction amount is calculated so as to reduce a suction air amount according to the shortage amount of the brake negative pressure which is the difference between the actual value of the brake negative pressure and the requirement value A for the brake negative pressure (S3), and the load of an air conditioner is limited to a limit value E of an air-conditioner duty value as an upper limit value which is calculated based on the shortage amount of the brake negative pressure (S4). In addition, the recovery of the brake negative pressure is determined by comparing the requirement value A for the brake negative pressure with the actual value of the brake negative pressure (S5), and the air conditioner is released from its load limitation when the brake negative pressure recovers from the shortage(S6).

摘要： PROBLEM TO BE SOLVED: To achieve quick sulfur poisoning recovery while reducing the increment of a fuel injection amount for an air-fuel ratio of a whole engine to be a theoretical air-fuel ratio or a rich air-fuel ratio during temperature rise control for the sulfur poisoning recovery of a catalyst. SOLUTION: In the temperature rise control for sulfur poisoning recovery of the NOx storing/reducing catalyst 9, part of cylinders is made into a rich air-fuel ratio and the other cylinders are made into a lean air-fuel ratio, and the air-fuel ratio A/F of the whole engine is the theoretical air-fuel ratio. The temperature rise control is executed on condition that a high engine load is predicted to be continued, in accordance with an automobile climbing a hill or its acceleration being a preset value or higher. In such a high engine load condition, homogeneous combustion at the theoretical air-fuel ratio is executed and the amount of fuel required for engine operation becomes a value sufficient for quick temperature rise of the NOx storing/reducing catalyst 9 during the temperature rise control.

摘要： PROBLEM TO BE SOLVED: To provide a trouble-diagnostic device for an intake air flow control valve to perform high-precise diagnosis of the trouble of the intake air flow control valve. SOLUTION: Since, when indication of a valve position based on a SCV 48 is different from an actual valve position, a fuel injection amount comes to a value improper to an actual valve position, a feedback correct factor FAF to correct a fuel injection amount so as to control an air-fuel ratio to a theoretical air-fuel ratio is regulated and comes to a value separate away from a reference value '1.0'. An average value FAFAV of a feedback correction factor FAF when an engine operation state is a stable state and indication to one valve position is made on the SCV 48 is stored. Thereafter, forced switch of the SCV 48 to other valve position is indicated and an average value FAFAV when an engine operation state is a stable state and the indication after switch is effected is stored. The presence of the occurrence of abnormality at the SCV 48 is decided based on the average value FAFAV.

摘要： PROBLEM TO BE SOLVED: To maintain output torque of an engine to reference torque to be a target regardless of an air-fuel ratio. SOLUTION: A reference air-fuel ratio is computed, and the target torque fluctuation quantity is computed. The torque fluctuation quantity of an engine is detected, and the reference air-fuel ratio is corrected with a feedback correction factor so that the detected torque fluctuation quantity becomes the target torque fluctuation quantity. Basic throttle opening for making the output torque of the engine reference torque at the time of an air-fuel ratio being the reference air-fuel ratio, is computed, and the basic throttle opening is corrected on the basis of the feedback correction factor to compute target throttle opening. A throttle valve is then controlled so that throttle opening becomes the target throttle opening. Reference torque is set to output torque of the engine obtained when the air-fuel ratio is a stoichiometric air-fuel ratio.
