PROBLEM TO BE SOLVED: To obtain a control device for an ETV capable of executing stable control while enhancing the responsiveness. SOLUTION: The ETV control device includes a motor for controlling the opening/closing of a throttle valve, a spring means for always urging the throttle valve to be closed, a PID command value computing means for computing a PID control command value by utilizing a throttle valve opening degree command value calculated based on an output signal of an accelerator opening degree sensor and a throttle valve opening degree calculated based on an output signal of a throttle valve opening degree sensor, and a spring force correction value computing means for computing a spring force correction value based on data of specifications of the spring means and a value of preload acting on the throttle valve. The motor is controlled based on a motor control command value generated based on the PID control command value and the spring force correction value. COPYRIGHT: (C)2009,JPO&INPIT
