摘要： A knock determination unit is configured to determine whether the internal combustion engine causes knocking. A knock control unit is configured to perform a knock control to correct an ignition timing on the basis of the determination. A water pump is configured to circulate cooling fluid of the internal combustion engine. A pump control unit is configured to perform a cooling control to control the water pump so as to further cool the internal combustion engine in a detection state, where the knock determination unit detects knocking, than in a non-detection state where the knock determination unit does not detect knocking.

摘要： When detecting the data showing an output characteristics of an air-fuel ratio sensor, the air-fuel ratio (feed air-fuel ratio) supplied to each cylinder is alternately changed to rich or lean by a predetermined ratio (X %). And then, the average value of the detected air-fuel ratio λ in the rich side and the lean side is respectively computed. A ratio between the variation width of the air-fuel ratio and the detection variation of the air-fuel ratio sensor 20 is computed as an output-characteristics correction value for correcting the dispersion in the output characteristics of the air-fuel ratio sensor. By correcting the air-fuel ratio detection of the air-fuel ratio sensor with this output-characteristics correction value, the dispersion in the output characteristics due to manufacturing tolerances, aged deterioration, etc. of the air-fuel ratio sensor is corrected.

摘要： An exhaust gas sensor for detecting oxygen concentration in exhaust gas is disposed in an exhaust pipe of an internal combustion engine. The sensor including a heater is controlled by a system that includes an electronic control unit. Water vapor contained in the exhaust gas is condensed on the sensor when the exhaust gas temperature is low. If the water condensation occurs while the sensor is heated by the heater, a sensor element may be cracked due to local cooling by the condensed water. To avoid the water condensation, the exhaust gas temperature is raised by retarding ignition timing of the engine for a certain period after the engine is started. After the exhaust gas is heated to a certain level, the sensor is heated. Alternatively, heating of the sensor is prohibited until the exhaust gas temperature becomes to a level at which no water condensation occurs. Thus, the cracking of the sensor element is avoided while making a delay of sensor activation minimal.

摘要： After an engine automatic stop processing is started, a diagnosis of a starter is started at a time of t1 when an engine speed drops to a diagnosis starting speed. Before the engine speed drops to the lower limit speed at which an engine can be restarted without being cranked by the starter, the diagnosis of the starter is conducted. In the diagnosis of the starter, it is determined whether the starter is faulty based on a current passing through the starter when a relay is turned off to stop energization of the starter before the starter actually rotates after the relay is turned on. Thereby, a malfunction of the starter can be detected before the engine is automatically stopped. It is avoided to automatically stop the engine which is incapable of being automatically restarted due to the malfunction of the starter.
