摘要： An air-fuel ratio control system for an internal combustion engine includes a pair of cylinder banks, a pair of exhaust passages connected to the cylinder banks, respectively, a common exhaust pipe where the exhaust passages join each other at their downstream ends, a pair of catalytic converters provided in the exhaust passages, respectively, a pair of main air-fuel ratio sensors provided in the exhaust passages upstream of the catalytic converters, respectively, a pair of auxiliary air-fuel ratio sensors provided in the exhaust passages downstream of the catalytic converters, respectively, and a catalytic converter provided in the common exhaust pipe. The system derives an air-fuel ratio feedback control correction value for each of the cylinder banks based on outputs of the auxiliary air-fuel ratio sensors. The system derives the air-fuel ratio feedback control correction values in such a manner as to control the outputs of the auxiliary air-fuel ratio sensors to be in antiphase with each other when the outputs of the auxiliary air-fuel ratio sensors are in phase with each other. This arrangement ensures effective purification of exhaust gases at the catalytic converter provided in the common exhaust pipe.

摘要： To inhibit an air pulsating sound resulting from the opening and closing of the air control valve in a cold engine and to improve controllability of ISC functions in an assist air supply apparatus. When an engine is cold based on a cooling water temperature sensor, opening control is performed so as to control the amount of supplied assist air by controlling the opening degree of an air control valve. When the engine is warming-up, injection synchronization control is performed, in which opening and closing of the air control valve are controlled in synchronization with fuel injection from the fuel injection valves. Therefore, it is possible to suppress air pulsating noise resulting from the opening and closing the air control valve when the engine is warming up and to improve controllability of ISC functions in an assist air supply apparatus.

摘要： For stable air-fuel ratio control without hunting, an output condition of an air-fuel ratio sensor is monitored to decide whether or not a modern or advanced control using a dynamic model may be performed. The appropriateness of using the dynamic model may be determined by monitoring whether the output value of an air-fuel ratio sensor exists in a predetermined range or whether the air-fuel ratio sensor is maintained stably in an air-fuel ratio detectable state. When the sensor output condition is out of the predetermined range suitable for the modern control, an optimum feedback gain for performing the modern control is switched over to a lowered gain or the modern control is switched over into normal feedback control by proportional-and-integral control. By this control mode switch-over, most appropriate air-fuel ratio feedback control may be performed.
摘要翻译： 为了在不进行狩猎的情况下进行稳定的空燃比控制，监视空燃比传感器的输出状态，以决定是否可以执行使用动态模型的现代或高级控制。 可以通过监视空燃比传感器的输出值是否存在于预定范围内，或者是否将空燃比传感器稳定地保持在空燃比可检测状态来确定使用动态模型的适当性。 当传感器输出条件超出适用于现代控制的预定范围时，用于执行现代控制的最佳反馈增益被切换到较低的增益，或者通过比例和积分将现代控制切换到正常的反馈控制 控制。 通过该控制模式切换，可以执行最合适的空燃比反馈控制。

摘要： The protection element of the present invention is constructed of a MOS capacitor composed of a semiconductor substrate, an insulating film formed on the semiconductor substrate and a word line formed on the insulating film. A well region having a conductivity type opposite to that of the semiconductor substrate is formed in a portion of the semiconductor substrate constituting the MOS capacitor. If charge exceeding the breakdown voltage of the insulating film constituting the MOS capacitor is induced in the word line, the induced charge is released into either the semiconductor substrate or the well region depending on whether the induced charge is positive or negative.

摘要： In a drive control system for a hybrid vehicle, the electric power generated by an alternator driven by an engine and the electric power regenerated by a motor-generator are stored in a battery. The battery discharges electric energy to drive the motor-generator. An ECU calculates fuel consumption of the engine and fuel consumption of the motor-generator, and determines a distribution of motive power between the engine and the motor-generator from the fuel consumptions. The ECU calculates fuel consumption contributing to the electric energy stored in the battery, and then calculates the fuel consumption of the motor-generator by reflecting the contributing fuel consumption in it.

摘要： A base engine torque generated with an estimated intake air amount is estimated. An engine torque is corrected by correcting an ignition timing based on a difference between a required engine torque and the base engine torque. A torque correction amount is calculated based on a correction amount of the ignition timing. An actual engine torque is estimated based on the calculated torque correction amount and the base engine torque. A permitted component driving torque is a difference between the actual engine torque and the required vehicle driving torque. A component is controlled based on the permitted component driving torque.

摘要： An air-fuel ratio sensor monitor is provided which is designed to monitor reactive characteristics or response rates of an air-fuel ratio sensor when an air-fuel ratio of a mixture to an internal combustion engine is changing to a rich side and to a lean side. The monitored response rates are used in determining whether the sensor is failing or not, in determining the air-fuel ratio of the mixture accurately, or in air-fuel ratio control of the engine.

摘要： An air-fuel ratio control system has an upstream catalyst, a downstream catalyst, a first sensor for detecting a first air-fuel ratio present upstream the upstream catalyst, a second sensor for detecting a second air-fuel ratio present between the catalysts and a third sensor for detecting a third air-fuel ratio present downstream the downstream catalyst. An ECU determines a target second air-fuel ratio based on the detected third air-fuel ratio, and a target first air-fuel ratio based on the target second air-fuel ratio and the detected second air-fuel ratio. The ECU feedback controls an air-fuel ratio of mixture based on the target first air-fuel ratio and the detected first air-fuel ratio. The target first air-fuel ratio is corrected based on the detected third air-fuel ratio so that a change in the target first air-fuel ratio becomes smaller in a predetermined range other than a normal range.

摘要： An air-fuel ratio detected by an air-fuel ratio sensor is periodically varied by executing a PI control. During the PI control, a time period in which the detected air-fuel ratio passes through a predetermined rich-side range is defined as a rich-side time constant, and a time period in which the detected air fuel ratio passes through a predetermined lean-side range is defined as a lean-side time constant. A rich-side time delay represents a time period in which an air-fuel correction amount is increasingly corrected to exceed a rich-side threshold, and a lean-side time delay represents a time period in which the air-fuel correction amount is decreasingly corrected to exceed a lean-side threshold. These time constants and time delays are compared with a determining value to diagnose degradation of an air-fuel ratio sensor.
