## Abstract

Provided are a method and apparatus for displaying energy flow in a hybrid vehicle. The present invention adds a function, which displays breakdown and abnormal state information on modules and is not provided by an energy flow displaying function of the existing hybrid vehicle, to the energy flow displaying function, thus removing inconvenience of the existing energy flow displaying function that cannot check information on breakdown and abnormal states of a vehicle.

## Claims

### Claim 1

An apparatus for displaying energy flow in a hybrid vehicle including an engine module, a motor module, a battery module, and a vehicle driving wheel module, in which power shift between the modules is displayed in the form of graphics, the apparatus comprising:
a graphics controller graphics-processing the respective modules into icons, receiving power shift information and breakdown state information from the respective modules, processing the power shift information into a line type of graphics indicating power shift between corresponding icons, and processing the breakdown state information into a text type of graphics indicating the breakdown state of each of the modules; and
a display unit simultaneously displaying the icons, the line type of graphics, and the text type of graphics on one screen according to control by the graphics controller.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the graphics controller processes the breakdown state information into graphics of a specific color.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the display unit changes a color of the screen to the specific color and displays the text type of graphics according to control by the graphics controller.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the graphics controller receives the breakdown state information through CAN communication.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the received breakdown state information comprises information, indicating a broken-down module, and information indicating a kind of breakdown of the broken-down module.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the kind of breakdown is a state in which power from the broken-down module is abnormally supplied.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein the display unit displays the abnormal supply state as letters.

### Claim 8

A method of displaying energy flow in a hybrid vehicle that includes an engine module, a motor module, a battery module, and a vehicle driving wheel module, and includes a head unit including a graphics controller processing power shift between the modules in the form of graphics and a display unit displaying the power shift as graphics according to control by the graphics controller, the method comprising:
graphics-processing, by the graphics controller, the respective modules into predetermined icons;
processing, by the graphics controller, power shift between corresponding icons into a line type of graphics on the basis of power shift information between the modules;
receiving, by the graphics controller, breakdown state information from the respective modules, and processing a breakdown state of each of the modules into a text type of graphics on the basis of the received breakdown state information; and
simultaneously displaying, by the display unit, the icons, the line type of graphics, and the text type of graphics on one screen according to control by the graphics controller.

### Claim 9 (depends on 8)

The method of claim 8, wherein the processing of a breakdown state into a text type of graphics comprises processing the breakdown state information into graphics of a specific color.
