Vehicle display device
View Patent ↗A vehicle display device is arranged in a vehicle having an idling stop function that automatically stops an engine when the vehicle temporarily stops. The device includes a control unit that calculates a deviation of a current instant fuel consumption with respect to an average fuel consumption in a past predetermined period of the vehicle; and a fuelometer that indicates fuel consumption information representing whether a current driving state of the vehicle decreases the average fuel consumption. When the vehicle is in the idling stop state, the fuelometer indicates that the deviation is 0 regardless of the instant fuel consumption and the average fuel consumption.
1. A vehicle display device arranged in a vehicle having an idling stop function that automatically stops an engine when the vehicle temporarily stops, the device comprising:
a control unit that calculates a deviation of a current instant fuel consumption with respect to an average fuel consumption in a past predetermined period of the vehicle; and
a fuelometer that indicates fuel consumption information representing whether a current driving state of the vehicle decreases the average fuel consumption,
wherein when the vehicle is in the idling stop state, the fuelometer indicates that the deviation is 0 regardless of the instant fuel consumption and the average fuel consumption.
2. The vehicle display device according to claim 1 ,
wherein the fuelometer is a meter with a needle arranged on an indication panel in a deflecting manner, the meter indicating the fuel consumption information by deflecting the needle in accordance with the deviation in a plus direction or a minus direction from a 0 position arranged on the indication panel, and
wherein when the vehicle is in the idling stop state, needle indicates the 0 position to indicate that the deviation is 0.
3. The vehicle display device according to claim 2 ,
wherein the fuelometer comprises the needle driven by the stepping motor, and
wherein when the vehicle is in the idling stop state, the control unit controls the stepping motor to be deflected by a predetermined angle at a position at which the needle indicates the 0 position.
4. The vehicle indication device according to claim 1 ,
wherein the fuelometer is a meter with a needle arranged on an indication panel in a deflecting manner, the meter indicating the fuel consumption information by deflecting the needle in accordance with the deviation in a plus direction or a minus direction from a 0 position indicated on the indication panel, and
wherein when the vehicle is in the idling stop state, an indicator lamp arranged near the 0 position of the indication panel is lit or blinked to indicate that the deviation is 0.
