ABSTRACT:
A throttle valve control system for an internal combustion engine electrically controls throttle valve angular position in order to control intake air flow rate through an air induction passage of an engine. The system employs an accelerator to produce a signal representative of a required or demanded output speed. Actual output speed is monitored by means of a speed sensor. The actual speed is compared with the output speed demand derived from the accelerator signal to obtain the difference therebetween. Feedback control is performed on the basis of the calculated difference so as to control the throttle valve angular position to increase or decrease the actual output speed toward the speed demand value.
