Claim Text:
1. A system for adjusting an engine throttle opening amount, the system comprising: a slope-determining unit configured to determine a longitudinal angle of inclination of a vehicle from one of a throttle request determining unit configured to determine a throttle request; and an engine control unit configured to control the engine throttle opening amount based on the determinations of the slope-determining unit and the throttle request determining unit on the condition that predetermined criteria is satisfied, wherein the engine control unit receives as inputs the angle of inclination of the vehicle determined by the slope-determining unit, the throttle request determined by the throttle request determining unit, and a current throttle opening amount, the engine control unit including: a calculating unit configured to calculate a slope gain factor based on the angle of inclination of the vehicle determined by the slope-determining unit; and a comparing unit configured to compare the slope gain factor to a predetermined threshold, wherein on the condition that the slope gain factor is greater than the predetermined threshold, the engine control unit is configured to generate a throttle command to increase the current throttle opening amount according to at least one predetermined setting based on the throttle request and the slope gain factor, wherein on the condition that the slope gain factor is less than or equal to the predetermined threshold, the engine control unit is configured to generate a throttle command that controls the throttle opening amount based on the throttle request and independently of the slope gain factor, and wherein the predetermined threshold is variable and is a function of at least one of an instantaneous speed of the vehicle and the angle of inclination of the vehicle.
