ABSTRACT:
Multiple control-request switches are operatively coupled by an electronic interlock circuit with an electronic engine control that controls an engine that powers a heavy duty automotive vehicle. The vehicle is also equipped with one or more devices, such as an air-compressor or hydraulic pump, that are powered from the engine via a power take-off. The control-request switches request control of this equipment from various stations via control of an operational function of the engine, such as control of engine speed. The interlock circuit functions to allow only a first-to-be-actuated of the control-request switches to acquire control so that subsequent actuation of any other switch causes the control to go to a default mode to avoid conflicting control of the engine and equipment powered through a power take-off.
