Abstract
An apparatus for controlling an opening angle of a throttle valve in an internal combustion engine. When an accelerator pedal is depressed by a vehicular driver, an accelerator drum attached onto an end wall of a main body of a single motor is rotated via an accelerator wire and the main body of the motor, a drive axle of the motor held with respect to the main body of the motor, and a rotation axle of the throttle valve are integrally rotated. When control is transferred from the above-described ordinary opening angle control state into a traction control state, the hold function of the motor is released and the motor is driven so as to reduce the opening angle of the throttle valve. It is possible to drive the motor so as to control the opening angle of the throttle valve, with the accelerator pedal released, to achieve an automatic cruise speed control and to drive the motor according to an accelerator pedal operating variable so that an arbitrary characteristic of the throttle valve opening angle control can be acheived.
