Abstract
A fuel economy display control method for a hybrid vehicle includes driving electric power supplied to a travel motor from a battery is generated by an electric power generation device that generates electric power by consuming fuel. The fuel economy display control method includes an electric power economy computation step in which instantaneous electric power economy according to an output of the travel motor is computed, a fuel economy computation step in which instantaneous fuel economy corresponding to the above instantaneous electric power economy is computed in accordance with an operating state set for the electric power generation device, and a display step in which the instantaneous fuel economy is displayed on a display device arranged inside a vehicle cabin.
