Abstract

PURPOSE:To enhance the accelerating performance in an arrangement, in which the throttle valve control characteristic in accordance to the accelerator operating amount is switched to power mode and economy mode, by switching into the power mode when the rate of acceleration change in accelerator operation exceeds a certain specified value. CONSTITUTION:A control unit 6 sets the degree of opening of a throttle valve 5 according to the amount of accelerator pedal stamping from an accelerator position sensor 9, and the throttle valve 5 is controlled through an actuator 7. The control characteristics for the amount of accelerator pedal stamping and the degree of throttle valve opening are so arranged that changeover can be made into either the power mode or economy mode. When the rate of acceleration change in accelerator operation exceeds a certain specified value, automatic switching is made into the power mode even though the selection is the economy mode.

FIG. 4 is a flowchart showing a specific example of the control operation by the control unit 6. As shown in FIG. When this flowchart starts, first, in step S1, the mode selection signal output from the selection switch 8 is input, and in step S2, it is determined whether the power mode has been selected by the selection switch 8. As a result of this judgment,
If it is confirmed that the power mode has been selected,
In step S3, the opening degree of the throttle valve 5 is calculated based on the above-mentioned power characteristics, and in step s4, a control signal corresponding to this control result is output to the actuator 7.

Furthermore, if it is confirmed that the economy mode has been selected as a result of the determination in step S2, then in step S5, the accelerator operation amount θ is read in accordance with the detection signal from the accelerator position sensor→No.9. Then,
In step S6, the value of this accelerator operation amount is compared with the stored value of the previous accelerator operation amount to calculate the rate of change in the accelerator operation amount during acceleration (acceleration change rate), and then in step S7 this change rate is calculated. Determine whether the value is greater than or equal to a predetermined value. As a result of this determination, if it is confirmed that the rate of change is below a predetermined value and there is no rapid acceleration, the opening degree of the throttle valve 5 is calculated based on the economy characteristic in step S8, and the opening degree of the throttle valve 5 is calculated in step S4. A control signal is output according to the result of this calculation. Further, as a result of the determination in step S7, if the rate of change is determined to be equal to or higher than the predetermined value and it is confirmed that the rapid acceleration state is present, the process moves to step S3, and the throttle valve 5 is adjusted based on the power characteristics. Calculate the opening.

In this way, by determining whether the rate of change in the amount of accelerator operation during acceleration is equal to or higher than a predetermined value, it is determined whether or not a sudden acceleration is occurring, and the selection state by the selection switch 8 is changed during sudden acceleration. Since the opening characteristic of the throttle valve 5 is set to the power mode regardless of the situation, the desired output characteristic can be obtained without the driver having to perform the complicated operation of switching the selection switch 8 to the power mode one by one. Can be done.

That is, when the economy mode is selected, under normal conditions, the opening degree T of the throttle valve 5 changes gradually compared to the change state of the accelerator operation amount θ, as shown by the broken line in the time chart of FIG. The opening degree T of the throttle valve 5 is set according to the economy mode to be used in order to improve fuel efficiency. However, when accelerating suddenly, the selection switch 8 is not operated and the accelerator is pressed as shown by the solid line in the above time chart. The opening degree T of the throttle valve 5 is set according to the power characteristic in which the opening degree T of the throttle valve 5 changes rapidly compared to the changing state of the manipulated variable θ, and the desired output torque can be obtained quickly. Responsiveness can be improved.
