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.

Disclosed is a fuel supply control device which can properly control fuel supply at any time by recovering within a short time in the event of out of phase in the drive of the step motor. In a fuel supply mechanism of an internal-combustion engine having a fuel supply control means for controlling the quantity of intake air or fuel supplied into the engine, a step motor for driving the fuel supply control means, and a control value output means for outputting control values to the step motor, the fuel supply control device comprises a position sensor for detecting the control position of the fuel supply control means, a out of phase detecting means for detecting the out of phase of the step motor from the control values supplied from the control value output means and the control position detected by the position sensor, a out of phase step value computing means for converting, into the number of steps of the step motor, a deviation between the control value and control positions at the time of detection of the out of phase condition of the step motor by the out of phase detecting means, and a control value correcting means for correcting the control values of the step motor by using the number of steps determined by the out of phase step value computing means.

Disclosed is a control device for internal-combustion engine which is capable of detecting an abnormality in accelerator pedal angle sensors throughout a range of accelerator pedal angles and continuing operation even when an abnormality is detected. It includes a first accelerator pedal angle sensor for detecting an accelerator pedal angle, a second accelerator pedal angle sensor for detecting the accelerator pedal angle, and a minor selection device for selecting, as the accelerator pedal angle, a lower value of one of the outputs of the first accelerator pedal angle sensor and the second accelerator pedal angle sensor.
摘要:
An apparatus of controlling an intake air throttle valve capable of obtaining the certain drive for the change in the load applied to the throttle valve due to the change in the intake air amount in the transient period, without any increase in current consumption and reduction in responsiveness. The apparatus includes a throttle valve for controlling an intake air amount in the internal combustion engine; a motor for electrically controlling the throttle valve; and a drive circuit for controlling the drive torque of the motor. It further includes a throttle valve opening defining device for defining a parameter indicating the opening of the throttle valve; a comparing device for comparing the value of the parameter defined by the throttle valve opening defining device; and a torque increasing device for increasing the output torque by the drive circuit when the comparing device judges that the value of the parameter is larger than the specified 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:
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.

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.

The content of operations is identified and an alert is generated to an operation having a high risk of information leakage.An agent monitors, for example, operations performed with respect to a dialogue displayed on a client PC. If a file is selected by an operation performed with respect to the displayed dialogue, the agent assigns an identifier indicating a source for the file to the file. If the file is sent as an attached file, the agent identifies an output destination for the attached file as well as the source for the attached file; and if the output destination for the attached file is an external Web server and the source for the attached file is a mail server, the agent generates an alert by determining that an unauthorized operation has been executed; and then sends the generated alert to a management server.
