ABSTRACT:
An automotive vehicle that is powered by an electronically-controlled engine, such as a truck that is powered by an electronically-controlled diesel engine, is equipped with dual sets of controls, one set on each side of the vehicle. The accelerator pedal of each set operates a corresponding accelerator pedal sensor, and the two accelerator pedal sensors are coupled with an electronic controller of the engine by a coupling circuit that includes diodes for blocking current flow from each sensor to the other so that neither sensor can impose a load on the other that would impair the accuracy of the pedal position signal from the one sensor that is actively connected to the controller to the exclusion of the other because that one sensor's pedal is more distant from idle that the other pedal.
