Abstract
A throttle control system for a vehicle includes a driver input that generates a control signal and a control module that generates a throttle control signal based on the control signal. The control module determines whether the throttle control signal is within one of a first and a second region, determines a compensation factor from a first look-up table when the throttle control signal is within the first region and determines the compensation factor from a second look-up table when the throttle control signal is within the second region. The control module calculates a compensated throttle control signal based on the compensation factor.
