Claims

[Scope of claim for utility model registration] Accelerator operation amount detection means for detecting the operation amount of the accelerator operation means operated by the driver, and throttle valve opening detection means for detecting the opening degree of a throttle valve provided in the intake system of the engine. a throttle valve opening target value setting means for setting a throttle valve opening target value according to a detected value of an accelerator operation amount; and a throttle valve for calculating a target value, a detected value, and a deviation of the throttle valve opening. The opening deviation is calculated in 1,000 steps, and the feedback control amount of the throttle valve opening according to the deviation is set as a non-linear characteristic with respect to the deviation so that the throttle valve opening gradually follows the change in the accelerator operation amount. Throttle valve opening control amount setting means and a control amount signal from the throttle valve opening control amount setting means! 1. An accelerator control device for an internal combustion engine for a vehicle, comprising a throttle valve driving means for driving a throttle valve to open and close based on the number of seconds.・
