Abstract

A method of displaying autonomous driving mode distance to empty (DTE) of a vehicle capable of autonomous driving includes: determining whether a destination is set; reading a preset gas mileage table; calculating in real time an autonomous driving condition factor to the destination; calculating the autonomous driving mode DTE based on the preset gas mileage table and the autonomous driving condition factor; and displaying the calculated autonomous driving mode DTE.

Claims

1. A method of displaying driver driving mode distance to empty (DTE) and an autonomous driving mode DTE of a vehicle capable of autonomous driving, the method comprising steps of:

displaying the driver driving mode DTE when the vehicle starts;

determining whether a destination is set;

calculating the autonomous driving mode DTE when the destination is set; and

additionally displaying the calculated autonomous driving mode DTE,

wherein a driving mode of the vehicle is allowed to be selected based on the DTEs separately displayed by the driving modes.

2. The method of claim 1, wherein the step of calculating the autonomous driving mode DTE comprises:

reading a preset gas mileage table;

calculating, in real time, an autonomous driving condition factor to the destination; and

calculating the autonomous driving mode DTE based on the preset gas mileage table and the autonomous driving condition factor.

3. The method of claim 2, further comprising:

compensating for the calculated DTE using an accumulated driving learning compensation factor obtained by learning after each autonomous driving.

4. The method of claim 1, further comprising:

renewing an accumulated driving learning compensation factor by learning after driving in an autonomous driving mode is completed.

5. The method of claim 1, wherein the driver driving mode DTE is calculated based both on a fixed gas mileage according to a vehicle type and on an accumulated driver-driving-mode learning gas mileage.

6. The method of claim 1, further comprising, after driving in an autonomous driving mode is completed:

additionally displaying a graph comparing variations of DTEs by the respective driving modes.

7. The method of claim 1, wherein the autonomous driving mode DTE is displayed only when the destination is set.

8. An apparatus for dually displaying distance to empty (DTE) by driving modes of a vehicle capable of autonomous driving, the apparatus comprising:

an output configured to always display driver driving mode DTE when the vehicle starts;

an input configured to input information about a destination; and

a calculator configured to calculate the dual DTE to be displayed on the output by the respective driving modes,

wherein the output additionally displays autonomous driving mode DTE calculated by the calculator.

9. The apparatus of claim 8, wherein the calculator calculates, when the information about the destination is inputted to the input, the autonomous driving mode DTE based on a preset gas mileage table and an autonomous driving condition factor to the destination which is calculated in real time, and compensates for the calculated autonomous driving mode DTE using an accumulated driving learning compensation factor obtained by learning after autonomous driving.

10. The apparatus of claim 8, wherein the calculator calculates, when the vehicle starts, the driver driving mode DTE based on a fixed gas mileage according to a vehicle type and an accumulated driver-driving-mode learning gas mileage.

11. The apparatus of claim 8, wherein, when the information about the destination is inputted, the dual DTE by the respective driving modes are simultaneously displayed to select a driving mode.

12. The apparatus of claim 8, wherein the output additionally displays a graph comparing variations of the dual DTE by the respective driving modes after the autonomous driving is completed.
