Abstract
Disclosed is a control device for internal-combustion engine which is capable of detecting an abnormality in accelerator pedal angle sensors throughout a range of accelerator pedal angles and continuing operation even when an abnormality is detected. It includes a first accelerator pedal angle sensor for detecting an accelerator pedal angle, a second accelerator pedal angle sensor for detecting the accelerator pedal angle, and a minor selection device for selecting, as the accelerator pedal angle, a lower value of one of the outputs of the first accelerator pedal angle sensor and the second accelerator pedal angle sensor.
