摘要： An electronic control apparatus for an engine of a vehicle has a first CPU for fuel control which controls the amount of fuel to be supplied to the engine and a second CPU for throttle valve control which outputs a driving signal to an actuator which operates to open or close the throttle valve disposed in an intake pipe to the engine. The apparatus has an opening degree computing member which is provided in the first CPU to compute an opening degree of the throttle valve based at least on an amount of depression of an accelerator and then to output a result thereof as an opening degree signal. The first CPU and the second CPU are connected together by a communication line which transfers the opening degree signal from the opening degree computing member from the first CPU to the second CPU.

摘要： There is provided a power output control system for an internal combustion engine, which enables the vehicle to smoothly perform refuge travel to find a place to park when an electric throttle control device becomes incapable of controlling a throttle valve, while ensuring adequate traveling performance. An ECU determines whether or not the electric throttle control device is 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 incapable of controlling the throttle valve. At this time, the opening of the throttle valve is held at the default opening degree by a spring. Further, basic ignition timing is calculated according to the engine rotational speed and load on the engine, and ignition timing of the engine is determined by correcting the calculated basic ignition timing according to the amount of operation of the accelerator pedal.

摘要： In the event that an abnormality is detected in a throttle valve driving apparatus, an upper limit value for a throttle valve opening is set according to a vehicle speed when a brake switch is not switched on. When the brake switch is on, the upper limit value is set at a predetermined idle opening. When the target opening which is calculated according to an accelerator pedal depression amount is larger than the upper limit value, the target opening is changed to the upper limit 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 secondary air supply control system controls supply of air to a catalyst arranged in the exhaust passage of an internal combustion, for purification of exhaust gases. A temperature difference between a temperature of an engine coolant sensed at a stoppage of the engine and stored and a temperature of the engine coolant sensed at a start of the engine after the stoppage is calculated. It is determined whether or not a stop time period between the stoppage and the start of the engine is short, depending on the temperature difference. When it is determined that the stop time period is short, an operation time period over which the air pump is to be operated to supply air to the catalyst is corrected based on a temperature difference between a temperature of the engine coolant sensed at the start of the engine and a temperature of intake air sensed at the start of the engine.
