Abstract
A method for displaying a distance to empty (DTE) of a vehicle include calculating an indicated distance to empty based on a learned fuel efficiency which is learned before starting. A target distance to empty is calculated based on an updated learned fuel efficiency which is updated until a present time. A driving mode is determined according to a difference between the indicated distance to empty and the target distance to empty. A final distance to empty is calculated according to the driving mode, and the final distance to empty is displayed.
Claims19
A method for displaying a distance to empty of a vehicle, comprising steps of:
- calculating an indicated distance to empty based on a learned fuel efficiency which is obtained before starting;
- calculating a target distance to empty based on an updated learned fuel efficiency which is updated until a present time;
- determining a driving mode according to a difference between the indicated distance to empty and the target distance to empty;
- calculating a final distance to empty according to the driving mode;
- and
- displaying the final distance to empty.
An apparatus for displaying a distance to empty of a vehicle, comprising:
- a fuel amount detector configured to detect a residual fuel quantity of a fuel tank;
- a vehicle information detector configured to detect a running state of the vehicle;
- a driving pattern map storage configured to check an accumulated driving pattern of a driver;
- a distance to empty calculator configured to calculate a final distance to empty by calculating an indicated distance to empty and a target distance to empty by receiving a signal from the fuel amount detector, the vehicle information detector, and the driving pattern map storage and determining a driving mode according to a difference between the indicated distance to empty and the target distance to empty;
- and
- a display configured to display the signal of the final distance to empty output from the distance to empty calculator.
