<p>PURPOSE: A display method of the instantaneous fuel efficiency of a vehicle is provided to display the instantaneous fuel efficiency of a vehicle to a preset valve according to the speed of a vehicle in low speed with classifying to 3 states according to the speed of a vehicle. CONSTITUTION: A display method of the instantaneous fuel efficiency of a vehicle comprises the following steps. Instantaneous fuel efficiency is calculated based on the injecting amount of fuel and the velocity of a vehicle. The instantaneous fuel efficiency is indicated by a display bar. The vehicle speed is classified to multiple states and the instantaneous fuel efficiency is indicated by turning on the display bar. The state is classified into a first state, a second state, and a third state. The first state is the speed from 0 to 5km/h. The second state is the speed from 5km/h to 10km/h. The third state is the speed over 10km/h. If the speed is within the third state, the display bar corresponding to the calculated instantaneous fuel efficiency is turned on(S22). If the speed is within the first state, the display bar corresponding to fixed lowest instantaneous fuel efficiency is turned on(S32).</p> |
