Description

The present invention relates to a vehicle display device, and more particularly to a vehicle display device that displays the remaining driving energy of the vehicle and the cruising distance.

Conventionally, various display devices for vehicles have been proposed in which information related to the own vehicle is displayed through, for example, a meter or a display provided on an instrument panel.

For example, Patent Document 1 provides a guideline when the institutional information is switched to an indicating state in order to prevent misunderstanding as if the institution is in an operating state even though the institution is in a stopped state. A vehicle display device is disclosed in which the display of vehicle information by the display unit and the liquid crystal display unit is temporarily stopped, and then the display of vehicle information is restarted by controlling the liquid crystal display unit.

Then, it is described in this Patent Document 1 that the image for notifying the cruising range is redisplayed on the liquid crystal display unit together with the fuel gauge (residual fuel) image (see FIG. 10 of Patent Document 1). ing.

Japanese Unexamined Patent Publication No. 2012-58027

By the way, with the spread of electric vehicles and fuel cell vehicles in recent years, the number of vehicle display devices that display the remaining battery power and the remaining hydrogen instead of gasoline is increasing. However, the relationship between the remaining battery power and the cruising distance is different from the relationship between the remaining gasoline and the cruising distance, so for users who are accustomed to the relationship between the remaining gasoline and the cruising distance. There is a problem that it is difficult to predict the cruising distance from the remaining amount of electric power and the remaining amount of hydrogen.

Therefore, it is desirable to always display the cruising distance, especially in a vehicle display device that displays the remaining battery power and the remaining hydrogen, but the cruising distance is, for example, a selected content in the liquid crystal display unit. Therefore, there is a problem that the user cannot see the cruising range unless he / she selects it, and cannot see other contents while selecting the cruising range.

Further, in the conventional vehicle display device, even when the remaining fuel and the cruising range are displayed at the same time, the remaining fuel and the cruising range are not clearly related to each other by simply displaying both side by side. Therefore, it is often unclear what the characters (including numbers) such as "○○○ km" indicating the cruising range represent. Therefore, in order to clarify that the characters such as "○○○ km" represent the cruising distance, as shown in FIG. 10 of Patent Document 1, a name such as "cruising distance" is given in the vicinity of such characters. Needed to be added.

In these respects, there is room for improvement in conventional vehicle display devices.

The present invention has been made in view of the above points, and an object of the present invention is to enable a vehicle display device to easily read the cruising distance without requiring explanation regardless of the type of driving energy. The purpose is to provide the technology.

In order to achieve the above object, in the vehicle display device according to the present invention, the image showing the cruising range is changed in correspondence with the visual change of the display means showing the remaining driving energy.

Specifically, the present invention is intended for a vehicle display device that displays the remaining driving energy of the vehicle and the cruising distance.

The vehicle display device is provided with a display capable of simultaneously displaying a plurality of images related to information related to the vehicle, including at least an image relating to the cruising range, and the remaining driving energy amount as the remaining driving energy amount changes. It is characterized in that at least one of the position and shape of the image with respect to the cruising range is changed on the display in correspondence with the visual change of the display means representing the above.

In the present invention, the "remaining amount of driving energy" is not only the "remaining amount of gasoline" in a conventional vehicle or a hybrid vehicle, but also the "remaining amount of battery power" in a hybrid vehicle or the like, or "hydrogen" in a fuel cell vehicle or the like. It includes "remaining amount" and the like.

Further, the "plurality of images related to vehicle-related information" may include an image relating to the remaining driving energy, and for example, when a meter or the like for displaying the remaining driving energy is combined with a display. , The image regarding the remaining amount of driving energy may not be included.

Based on these assumptions, according to this configuration, a display capable of simultaneously displaying a plurality of images related to vehicle-related information, including at least an image relating to the cruising range (hereinafter, also referred to as a cruising range image) is provided. Therefore, the user can see the cruising range without selecting the content, and can also see other information at the same time.

Further, since at least one of the position and shape of the cruising range image is changed in correspondence with the visual change of the display means representing the remaining driving energy, for example, a vertical bar graph (image) showing the remaining driving energy. If the number decreases, the position of the cruising range image changes (decreases) accordingly, so that the cruising range image (for example, a character image (including a numerical image) such as "○○○ km") can be navigated. The user can easily recognize that the distance is represented. That is, the user can easily recognize that the character image is the cruising distance without adding a name or the like explaining that the character image represents the cruising distance, whereby the user can navigate. The distance can be easily read.

Moreover, while displaying the remaining driving energy and the cruising distance at the same time, the cruising distance image is changed in response to changes in the remaining driving energy, so that you are accustomed to the relationship between the remaining amount of gasoline and the cruising distance. Even a user who has closed the vehicle can easily grasp the cruising distance when the driving energy is battery power, hydrogen, or the like.

As described above, according to the present invention, the cruising range can be easily read without requiring explanation regardless of the type of driving energy.
