1. A method of controlling fueling of an engine during a vehicle launch, comprising the steps of:
- (a) determining whether there is a high throttle demand upon said engine;
(b) calculating a throttle ramp rate offset based on an estimated weight of said vehicle when said high throttle demand is present; and
(c) adjusting a default high throttle ramp rate based upon said calculated throttle ramp rate offset.

Abstract
A system and method for controlling a throttle ramp rate of a vehicle. According to an embodiment of the invention, the controlling of a throttle ramp rate of a vehicle is accomplished by determining the target engine speed for a vehicle during a vehicle launch. If it is determined that there is a high throttle demand upon the engine of the vehicle, a throttle ramp rate offset amount is determined, which is based upon an estimated weight of the vehicle. A default high throttle ramp rate may then be adjusted based upon the determined throttle ramp rate offset.

14. A system of controlling fueling of an engine during a vehicle launch, comprising:
-
(a) an engine;
(b) a transmission system;
(c) a clutch connecting said engine to said transmission system;
(d) a throttle sensor for monitoring one or more throttle operating parameters; and
(f) a control unit, in communication with at least said throttle sensor and said engine, for detecting a high throttle demand and obtaining an estimated weight of said vehicle;
wherein upon detecting said high throttle demand, said control unit adjusts a default high throttle ramp rate based upon said estimated weight of said vehicle. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
