Apparatus for controlling internal combustion engine

Abstract

An apparatus for controlling an internal combustion engine comprises a position sensor for detecting an operational position of an accelerator pedal operated by a driver, a microprocessor for generating a target throttle valve opening in accordance with a predetermined function in response to the operational position of the accelerator pedal, and a servo motor provided with a throttle valve opening sensor and a servo drive circuit for controlling the opening of the throttle valve of the engine to the target throttle valve opening. In the microprocessor, there is provided a compensation circuit for compensating, during the acceleration, for the target throttle valve opening in response to the operational positions of the accelerator pedal immediately before and after the acceleration and an engine operational parameter immediately before the acceleration.

Description

Claims

1. An apparatus for controlling an internal combustion engine comprising an accelerator pedal operational position detector for detecting an operational position of an accelerator pedal that is operated by a driver; a target throttle valve opening generator for generating a target throttle valve opening in accordance with a predetermined function in response to the operational position of the accelerator pedal; and a throttle valve controller for controlling an opening of a throttle valve of an engine to said target throttle valve opening, wherein means is provided for compensating, during acceleration operation, for the target throttle valve opening in response to operational positions of the accelerator pedal immediately before and after the acceleration operation and an operational parameter of the engine immediately before the acceleration.
