Abstract
A method for comprehensive integrated control of an internal combustion engine, such as a compression-ignition engine, utilizing an electronic control module (20) is disclosed. The control strategy integrates various functions of engine control including an acceleration balance test for the engine cylinders, a fuel economy vehicle speed limit adder, a fueling limit for high altitude vehicle operation, throttle logic, a data-hub for operation trending and vehicle component lifing analyses, a gear ratio torque limit, an air temperature based torque limit, enhanced cooling fan control, and an idle shutdown strategy based on ambient air temperature.
