摘要： An output limiting control is carried out for limiting an output of a driving source when an acceleration pedal as well as a brake pedal is operated at the same time. An acceleration opening degree for a malfunction diagnosis is set based on a detected acceleration opening degree. A required output value for the malfunction diagnosis is calculated based on the acceleration opening degree for the malfunction diagnosis. A malfunction determining threshold is set in accordance with the required output value. An estimated output value of the driving source is compared with the malfunction determining threshold in order to determine whether there is a malfunction in a control system for the driving source. The acceleration opening degree for the malfunction diagnosis is limited to a predetermined limiting value, when the acceleration and brake pedal are operated at the same time.

摘要： Erroneous malfunction determination of an oxygen sensor is avoided by consideration of combustible substance penetrating to an air electrode side of the oxygen sensor. The combustible substance is determined whether it has penetrated to the air electrode of the oxygen sensor. If it is determined so, then it is determined whether the oxygen deficiency has disappeared, and the sensor malfunction determination operation is disabled until the oxygen deficiency at the air electrode is eliminated. At the same time, malfunction determination is also disabled.

摘要： When a specified learning execute condition is established, the high-pressure pump is stopped so that the fuel pressure in the high pressure fuel passage is made equal to the fuel pressure in the low pressure fuel passage. A low pressure fuel control is executed to control a driving voltage of the low-pressure pump based on the operational characteristic of the low-pressure pump. A driving voltage of the low-pressure pump is gradually corrected so that the difference between the detected high fuel pressure and a target low fuel pressure becomes small. A driving voltage correcting amount is learned as the control error of the low pressure fuel control. The driving voltage correction amount is stored as the learning correction amount, and the driving voltage of the low-pressure pump is corrected by means of the learning correction amount.

摘要： A variable valve timing adjusting mechanism includes one-way valves in a hydraulic supply passage in an advance hydraulic chamber and in a retard hydraulic chamber respectively and a drain oil passage bypassing each of the one-way valves disposed in parallel in the hydraulic supply passage of each hydraulic chamber. Drain switching valves are disposed in the respective drain oil passages. A controller opens the drain switching valve in a side of the hydraulic chamber where oil is discharged when a deviation between a target displacement angle and an actual displacement angle is more than a predetermined value to perform the maximum speed control for driving the adjusting mechanism in a direction of the target displacement angle at the maximum speed. The controller closes the drain switching valve in a side of the hydraulic chamber where oil is discharged when the deviation between the target displacement angle and the actual displacement angle is small to perform the holding control for stopping/slowing the variable operation of the adjusting mechanism.

摘要： One-way valves are provided in a hydraulic pressure supply passage in an advance hydraulic chamber and a hydraulic pressure supply passage in a retard hydraulic chamber respectively. A drain oil passage bypassing each of the one-way valves is provided in the hydraulic pressure supply passage in the each hydraulic chamber to be in parallel therewith. A drain switching valve is provided in the each drain oil passage. A drain switching control function for switching the hydraulic pressure driving the each drain switching valve is integral with a function of the hydraulic control valve for controlling the hydraulic pressure supplied to the advance hydraulic chamber and the retard hydraulic chamber. It is determined whether the responsiveness of an advance/retard operation is in a normal range based upon a changing rate of the VTC displacement angle during advance/retard operating, thereby determining presence/absence of abnormality in the advance/retard operation.

摘要： A system for exactly detecting any unstable state in which disturbance is caused on the output value of a thermal air flowmeter for measuring intake air flow rate, thereby preventing or promptly suppressing the generation of undesirable states such as a variation in the air-fuel ratio or rough idling.The system has an upstream intake air temperature sensor for detecting the temperature of the intake air before entering an air cleaner element, the above-mentioned thermal air flowmeter, and a downstream air temperature sensor for detecting the temperature of the intake air after passing the thermal air flowmeter. The system determines that the air flow rate output of the thermal air flowmeter is unstable, when the difference between the air temperature values detected by the upstream and downstream intake air temperature sensors exceeds a predetermined value, and executes a control process which has been determined to cope with such an unstable state. Whether an unstable state exists or not may be determined from the amount of variation of the output value from the thermal air flowmeter.

摘要： A fuel vapor purging control system is provided. This system includes a fuel vapor collection canister, a purge control valve for controlling a purge flow rate of fuel vapors purged from the canister, a purge air induction passage communicating between the canister and an air inlet port which is exposed to atmospheric pressure, an air pump for supplying pressurized air to the canister through the purge air induction passage, a pressure sensor for detecting negative pressure in an induction system of the engine, and a purge air control unit. When the engine falls to a relatively high load level and the negative pressure becomes smaller than a preselected threshold value, the purge air control unit directs the pressurized air from the air pump to the canister for assuring a desired purge flow rate during each engine operation.

摘要： In a cooling system of an internal combustion engine, coolant flowing through a radiator and bypassing the radiator are mixed in a flow control valve controlled by ECU on the basis of signals provided by sensors such as a coolant temperature sensor, so that the coolant is circulated by an electric pump to control the coolant temperature for the internal combustion engine. A desired coolant temperature is changed according to the operating condition of the internal combustion engine, the traveling condition of a vehicle and the ambient condition. A fluid control valve controls the flow rate of cooling water through the bypass passage. The flow control valve is diagnosed for abnormalities. If it is determined that the flow control valve is in an abnormal condition, a heat generation rate reducing control operation is executed to reduce the heat generation rate of the internal combustion engine.
