Hybrid vehicle display device
View Patent ↗A display device is provided with a fuel gauge ( 40 ) that displays the amount of fuel remaining in a fuel tank ( 24 ) (remaining amount) of a hybrid vehicle ( 10 ) provided with an engine ( 13 ) that consumes fuel supplied from the fuel tank ( 24 ) and generates power by driving wheels ( 15 ) or rotating a motor ( 11 ). The hybrid vehicle is provided with a non-traveling/non-power generating mode, or in other words, a fuel consumption mode or an engine maintenance mode in which the engine ( 13 ) is forced to run and consume fuel for purposes other than traveling or generating power. Of the fuel ( 41 a ) displayed in the fuel gauge ( 40 ), the region ( 41 aa ) corresponding to the amount of fuel consumed in the non-traveling/non-power generating mode is displayed so as to be distinguishable by color from another region ( 41 ab ).
1. A display device for a hybrid vehicle including
a motor that drives a wheel with electric power supplied from a battery,
an engine that consumes fuel supplied from a fuel tank, and drives the wheel or generates electricity for the motor, and a controller that controls the motor and the engine in
a non-traveling non-power generating mode in which the engine is forced to run to consume the fuel for preventing deterioration and change in quality of the fuel remaining in the fuel tank, the display device comprising:
a fuel gauge having a remaining amount display portion that displays the amount of the fuel remaining in the fuel tank;
the remaining amount display portion including a first region that displays an amount of fuel to be consumed in the non-traveling non-power generating mode, and a second region that displays an amount of fuel corresponding to a value obtained by subtracting the amount of fuel to be consumed in the non-traveling non-power generating mode from the amount of fuel remaining in the fuel tank,
wherein when the hybrid vehicle performs in the non-traveling non-power generating mode, a display in the non-traveling non-power generating mode, a display in the remaining amount display portion is switched from displaying only the amount of the fuel remaining in the fuel tank to displaying the first region and the second region.
2. The display device for a hybrid vehicle according to claim 1 , wherein
an area of the first region decreases while the non-traveling⋅non-power generating mode is performed.
3. The display device for a hybrid vehicle according to claim 1 , wherein
the battery is rechargeable using an external commercial power source.
4. The display device for a hybrid vehicle according to claim 1 , wherein
the non-traveling⋅non-power generating mode is a fuel consumption mode for preventing deterioration and change in quality of the fuel remaining in the fuel tank.
5. The display device for a hybrid vehicle according to claim 1 , wherein
the non-traveling⋅non-power generating mode is an engine maintenance mode for maintaining an appropriate functioning of the engine.
6. The display device for a hybrid vehicle according to claim 1 , wherein
a color of the second region is different from a color of the first region.
7. The display device for a hybrid vehicle according to claim 1 , further comprising:
a display portion that prompts a driver of the hybrid vehicle to refuel when a specified amount of fuel has been consumed in the non-traveling non-power generating mode.
8. A hybrid vehicle, comprising:
a motor that drives a wheel with electric power supplied from a battery;
an engine that consumes fuel supplied from a fuel tank, and drives the wheel or generates electricity for the motor;
a controller that controls the motor and the engine in a non-traveling⋅non-power generating mode in which the engine is forced to run to consume the fuel for a purpose other than travelling and power generation;
a fuel gauge having a remaining amount display portion that displays the amount of fuel remaining in the fuel tank;
the remaining amount display portion including a first region that displays an amount of fuel to be consumed in the non-traveling⋅non-power generating mode, and a second region that displays an amount corresponding to a value obtained by subtracting the amount of fuel to be consumed in the non-traveling⋅non-power generating mode from the amount of fuel remaining in the fuel tank.
