Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular display device for displaying vehicular information such as remaining fuel amount and traveling distance.

[0002]

2. Description of the Related Art Conventionally, an electronic display device has been used to display vehicle information such as a remaining fuel amount and a mileage in a vehicle. In many of such electronic display devices, in order to suppress the consumption of the vehicle-mounted battery, the ignition key is turned off when the ignition key is in the off state. In recent years, in order to prevent theft of vehicles, the number of vehicles that do not display the remaining fuel amount is increasing when the ignition key is off.

[0003]

However, in the above-mentioned vehicle, the ignition key has to be turned on when the vehicle information is checked while the vehicle is parked or the like, which is inconvenient.

An object of the present invention is to provide a vehicle display device capable of displaying vehicle information as needed even when the ignition key is off.

[0005]

According to a first aspect of the present invention, there is provided a vehicle display device comprising: first detection means for detecting that an ignition key is in an off state; and a vehicle information display switch for displaying vehicle information. A second detection means for detecting that the vehicle is on and a first detection means for detecting whether the ignition key is in the off state are provided with an illumination lamp or an instrument type lamp that does not display vehicle information. The vehicle information display means and the first detection means detect that the ignition key is in the off state, and the second detection means detects that the vehicle information display switch for displaying the vehicle information is in the on state. In this case, the vehicle information display control means for displaying the vehicle information in the vehicle information display means is provided.

According to the vehicle display device of the first aspect, when it is desired to check the vehicle information while the vehicle is parked, the vehicle information display switch is turned on without turning on the ignition key. Only, the vehicle information can be easily confirmed on the vehicle information display device with the illumination lamp or the instrument type.

The display device for a vehicle according to claim 2 is
The vehicle information display switch is a trip switch, and the vehicle information display means is a zero-return type fuel gauge. According to the vehicle display device of the second aspect, even when the zero fuel type fuel gauge is used to display the remaining fuel amount, the fuel remaining amount can be easily maintained by simply turning on the trip switch. You can check the quantity.

DETAILED DESCRIPTION OF THE INVENTION A vehicle display device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block configuration diagram of a vehicle display device 2 according to an embodiment. As shown in this figure, the vehicle display device 2 is provided with a switch input determination unit 10 and a display drive control unit 12.

A battery voltage VB, an ignition key switch 14 and a trip switch 16 are connected to the switch input judging section 10. The switch input determination unit 10 detects the operating states of the ignition key switch 14 and the trip switch 16, and outputs the information to the display drive control unit 12.

Further, the display drive control unit 12 includes a display 18 with a backlight such as an odometer arranged on an instrument panel or the like and a zero-reset type instrument 20 such as a fuel gauge.
Are connected. The display drive control unit 12 uses the ignition key switch 14 in the switch input determination unit 10.
Based on the determination result of the operating state of the trip switch 16, the display device 18 and the zero-reset type instrument 20 are controlled to display or not display the vehicle information.

Next, the display of the vehicle state in the vehicle display device according to the embodiment of the present invention will be described.
First, the switch input determination unit 10 receives the operation state signal of the ignition key switch 14 (step S10) and also receives the operation state signal of the trip switch 16 (step S11). Here, it is determined whether or not the ignition key switch 14 is in the ON state (step S12), and when the ignition key switch 14 is in the ON state, the indicator 18 with a backlight such as an odometer and the like. Vehicle information is displayed on the zero-reset instrument 20.

On the other hand, when the ignition key switch 14 is in the off state (step S12), it is determined whether the trip switch 16 is on (step S13), and the trip switch 16 is in the on state. Is an indicator 1 with a backlight such as an odometer
Vehicle information is displayed on a zero-reset type instrument 20 such as a fuel cell gauge 8 and a fuel gauge. When the trip switch 16 is off, vehicle information is not displayed on the backlit display 18 and the zero-reset instrument 20. Therefore, even if the ignition key switch 14 is in the off state, simply turning on the trip switch 16
Vehicle information can be displayed on the display 18 and the instrument 20.

In this vehicle display device, when it is desired to check the vehicle information while the vehicle is parked, the vehicle information display switch can be easily turned on without turning the ignition key on. You can check the information. Even when the remaining fuel amount is displayed using a zero-reset type fuel gauge, the instrument is driven to display the remaining fuel amount only when the trip switch is turned on, so the battery consumption is reduced. It is possible to easily confirm the remaining fuel amount as necessary while suppressing the fuel amount.

In the above embodiment, when the ignition key switch 14 is in the off state,
When the trip switch 16 is turned on, vehicle information is displayed on all of the indicator 18 with a backlight such as an odometer and the zero-reset type instrument 20 such as a fuel gauge. Based on the number of times of operations of the display 18 and the meter 20, the display 18 or the meter 20 that displays the vehicle information is selected, and the selected display 18
Alternatively, the vehicle information may be displayed on the instrument 20.

[0015]

According to the present invention, when it is desired to check the vehicle information while the vehicle is parked or the like, the vehicle information display switch is turned on without the ignition key being turned on, and the illumination lamp is attached. Alternatively, the vehicle information can be easily confirmed on the instrument-type vehicle information display device. Further, when the vehicle information display switch is a trip switch and the vehicle information display means is a zero-return type fuel meter, the trip switch is simply turned on, and the zero-return type fuel gauge is used for easy fuel consumption. You can check the remaining amount.
