Abstract
A fuel economy (FE) indicator lamp regulation system for a hybrid electric vehicle having an internal combustion engine includes an FE indicator lamp, a first module that calculates an instantaneous FE of the hybrid electric vehicle and a second module that determines a velocity of the hybrid electric vehicle. A third module switches the FE indicator lamp between an on state and an off state based on the instantaneous FE and the vehicle speed.
