ABSTRACT:
A system for controlling fueling of an internal combustion engine based upon vehicle position includes a receiver associated with the vehicle that is capable of receiving position and altitude information. The vehicle includes a control computer that delivers control signals to an engine fueling system, as well as to a turbocharger control system. The control computer includes a module that receives the altitude information and uses that information to evaluate changes in ambient air pressure that might detrimentally affect turbocharger speed. In one embodiment, the control computer reduces the fueling signal to reduce engine speed in relation to a decrease in ambient air pressure accompanying an increase in vehicle elevation. In another embodiment, the control computer uses the highly accurate altitude information together with engine speed information provides signals to the turbocharger control system.
