Abstract
An accelerator control system having an analog pedal position sensor and an idle switch capable of generating complementary output signals indicative of pedal position. The system includes a control circuit which commands the engine to an idle speed if the analog sensor indicates an idle state or if the complementary output signals together indicate an idle state. The system overrides the idle switch in the absence of complementary output signals therefrom and allows operation in response to the pedal position sensor as long as its output signal is within a predetermined range. Provision is made for operation at a reduced performance level in the event of an out-of-range failure of the analog sensor if the complementary output signals together indicate a non-idle condition.
