Abstract
A vehicle having an internal combustion engine with a throttle control is disclosed. The throttle control is responsive to a vehicle operator to generate a throttle setting signal to adjust vehicle speed. An operator-controlled input device is also provided to generate a selected signal corresponding to a selected one of a number of predetermined engine control relationships. A controller responds to the selection signal to govern engine operation in accordance with the selected one of the relationships and the throttle setting signal. The throttle control has a different performance characteristic for each of the relationships and is adjustable by the operator to increase or decrease speed for each of the relationships. The relationships may each correspond to a different type of engine governing technique and include different droop characteristics.
