Claims

[Scope of Claim for Utility Model Registration] An accelerator sensor that detects the depression state of the accelerator pedal, a throttle sensor that detects the opening degree of the throttle valve, an actuator that drives the throttle valve, and the actuator. a controller that outputs a drive signal according to the signal from the accelerator sensor; and a correction device provided in the controller that inputs the signals from the accelerator sensor and the throttle sensor to give a dartspot effect to the throttle valve. a throttle valve driving device comprising a circuit, wherein the correction circuit includes an integrating circuit that integrates a signal from an accelerator sensor, and a throttle valve opening degree based on a signal from the throttle sensor that is equal to or less than a predetermined reference value. a detection circuit that detects that the discharge voltage of the integration circuit and the signal from the accelerator sensor are input, and a maximum value discrimination circuit that outputs the higher level of either; a switch provided between the discriminator circuit and the switch that is switched in response to the detection signal of the detection circuit;
When the throttle valve reaches the predetermined value, the switch is turned on by a detection signal from the detection circuit, and the discharge voltage of the integrating circuit is input to the maximum value discrimination circuit, thereby determining the throttle value for the depressed state of the accelerator pedal. A throttle valve driving device characterized in that the driving signal is corrected by a predetermined time constant set by the integrating circuit in order to increase response delay of the valve.
