摘要： An evaporative fuel control system for an internal combustion engine having a throttle valve includes a canister for adsorbing evaporative fuel generated in the fuel tank, a purging passage for purging evaporative fuel into the intake system of the engine, and a purge control valve for controlling a flow rate of the evaporative fuel to be purged into the intake system through the purging passage. An ECU sets an air-fuel ratio correction coefficient applied in air-fuel ratio feedback control, based on the concentration of a specific component in exhaust gases emitted from the engine, calculates a first learned value of the air-fuel ratio correction coefficient during execution of the air-fuel ratio feedback control, and controls the purge control valve such that the flow rate of the evaporative fuel is changed according to the calculated first learned value. A second learned value of the air-fuel ratio correction coefficient suitable for the transient operating condition of the engine is calculated. When the engine is in a transient operating condition, the first learned value is set to the second learned value.

摘要： There is provided a control system for a vehicle, which enables the vehicle to smoothly travel only to find a place to park when an electric throttle control device is in a condition incapable of controlling a throttle valve, thereby improving drivability. An ECU determines whether or not the electric throttle control device is in the condition incapable of controlling the throttle valve, and interrupts energization of the electric throttle control device when it is determined that the electric throttle control device is in the condition incapable of controlling the throttle valve. The throttle valve is held at a default opening position by a spring when the electric throttle control device is determined to be in the condition incapable of controlling the throttle valve. A throttle valve opening sensor detects a degree of opening of the throttle valve. The speed position of an automatic transmission is controlled to a highest speed position if the detected degree of opening of the throttle valve is equal to or smaller than a predetermined reference value when the electric throttle control device is determined to be in the condition incapable of controlling the throttle valve.

摘要： A fuel supply control system for an internal combustion engine installed in a vehicle controls fuel supply to the engine such that supply of fuel to the engine is interrupted when the rotational speed of the engine exceeds a first predetermined value, and the supply of fuel to the engine is resumed when the rotational speed of the engine decreases a second predetermined value which is lower than the first predetermined value. The first predetermined value is decreased when the temperature of the engine exceeds a predetermined value over a predetermined time period. The operation of at least one of accessories of the vehicle is interrupted when the first predetermined value is decreased.

摘要： Failure of a valve timing changeover control system of an internal combustion engine is detected by comparing a present value of an air-fuel ratio feedback control correction coefficient which is varied in response to output from an O.sub.2 sensor with a predetermined value of the correction coefficient obtained based on values of same obtained during the feedback control of the air-fuel ratio. Alternatively, or in combination, failure of the valve timing changeover control system is detected by determining whether a present value of the correction coefficient obtained with respect to each of a plurality of cylinders of the engine in response to output from each of O.sub.2 sensors corresponding to the each cylinder is outside a predetermined range of deviation of values of the correction coefficient from a reference value, the deviation resulting from differences in characteristics between the cylinders.

摘要： Failure of a valve timing changeover control system of an internal combustion engine is detected by the steps of: (1) setting a predetermined state of intake air to be supplied to the engine depending on a control signal for controlling changeover of valve timing, (2) detecting a state of intake air being supplied to the engine, (3) comparing the detected state of intake air with the set predetermined state of intake air, and (4) detecting from the result of the combustion whether or not there is failure in the valve timing changeover control system.
