A vehicle display device comprising: an image display means; and a control means for displaying an image on the image display means,
The control means includes
In switching from the first screen having the first title image and the first content image to the second screen having the second title image and the second content image,
A first procedure for attenuating the brightness of the first screen;
A second procedure of hiding the first content image and displaying a part of the second screen at a predetermined position in a region where the first content image is hidden;
A third procedure for hiding the first title image and displaying the entire second screen;
It is characterized by performing.

  ADVANTAGE OF THE INVENTION According to this invention, the display apparatus for vehicles which can perform the screen switching display with a high display quality by an inexpensive structure can be provided.

1 is an external front view of a vehicle display device according to an embodiment of the present invention. The electrical block diagram of the display apparatus for vehicles which concerns on the same embodiment. The figure which shows the screen switching procedure of the display apparatus for vehicles which concerns on the embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a display device 1 for a vehicle according to an embodiment of the present invention uses a pointer-type meter 2 and an image display means 3 in combination to drive the vehicle speed, engine speed, current time, and audio. Information such as information is displayed.

  As shown in FIG. 2, the vehicle display device 1 mainly includes a pointer-type instrument 2, an image display unit 3, a control unit 4, a vehicle information input unit 5, and an operation unit 6.

  The pointer-type meter 2 is a meter that displays a predetermined measurement value by instructing to rotate a predetermined portion on the dial on which an index composed of figures and numbers is printed with the pointer. As shown in FIG. 1, the pointer-type meter 2 includes a speedometer that displays the traveling speed of the vehicle and an engine speedometer that displays the engine speed of the vehicle.

  The image display means 3 is, for example, a liquid crystal display or an organic EL display. The image display means 3 displays a predetermined image in response to a control signal from the control means 4.

  The control means 4 is composed of a circuit board on which a microcontroller having a CPU, a memory for storing various programs to be displayed on the image display means 3 and a program operated by the CPU, and a timer for measuring time is mounted. The The control means 4 performs overall control of the vehicle display device 1, and the vehicle information obtained from the vehicle information input means 5, the time measured by the timer, etc. are displayed on the pointer-type instrument 2 and the image display means 3. Display various information.

  The vehicle information input unit 5 is an in-vehicle network such as a CAN (Controller Area Network), for example, and inputs vehicle information such as a traveling speed of the vehicle, an engine speed, and trend information of various vehicle devices to the control unit 4.

  The operation means 6 is operated by a vehicle passenger such as a switch or a touch panel, and inputs a request for switching the screen displayed by the image display means 3 to the control means 4.

  Next, the procedure for switching the screen displayed on the image display means 3 which is a feature of the present invention will be described with reference to FIG. The control means 4 switches the display of steps S1 to S6 in FIG. 3 every 50 ms (milliseconds) from the first screen 30 displaying the current time to the second screen 31 displaying the fuel consumption of the vehicle. It is displayed on the image display means 3.

(Step S1)
The control means 4 displays, as the first screen 30 displaying the current time, a first title image 30a indicating the subject of the first screen 30 and a first content image 30b indicating the contents of the first screen 30. It is displayed on the means 3. When the screen switching request is input from the operation unit 6, the control unit 4 starts displaying step S <b> 2 to switch the screen from the first screen 30 to the second screen 31 that displays the fuel consumption of the vehicle.

(Step S2)
The control unit 4 attenuates the display brightness of the first screen 30. That is, the first title image 30a and the first content image 30b are displayed darkly. It is preferable that the display luminance is gradually attenuated step by step.

(Step S3)
When the display of step S2 is finished, the control means 4 hides the display of the first content image 30b, and displays the second title indicating the title of the second screen at the lower end of the area where the first content image 30b was displayed. The image 31a is displayed, and the first content image 30b is displayed in the area where the second title image 31a is not displayed in the area where the second content image 31b whose display brightness is attenuated in step S2 is displayed. One blank image 30c is displayed.

(Step S4)
When the display of step S3 is completed, the control means 4 moves the second title image 31a toward the upper end of the area where the first content image 30b was displayed at the time of step S2, and at the time of step S2, the second title image 31a is moved. A second blank image 31c, which is the background of the second content image 31b indicating the content of the second screen, is displayed below the second title image 31a in the area where the one content image 30b was displayed. The first blank image 30c is displayed above the second title image 31a in the area where the one content image 30b was displayed.

(Step S5)
When the control unit 4 finishes displaying the second title image 31a reaching the upper end of the area where the first content image 30b was displayed at the time of step S2 in step S4, the first title image 30a is displayed at the time of step S2. The second title image 31a is displayed in the displayed area, and the second blank image 31c is displayed in the entire area where the first content image 30b was displayed at the time of step S2.

(Step S6)
When the display of step S5 is completed, the control means 4 displays the second content image 31b in the area where the second blank image 31c was displayed at the time of step S5.

As described above, the vehicle display device 1 according to the present embodiment is a vehicle display device 1 including the image display unit 3 and the control unit 4 that causes the image display unit 3 to display an image. The means 4 switches the first screen 30 from the first screen 30 having the first title image 30a and the first content image 30b to the second screen 31 having the second title image 31a and the second content image 31b. A first procedure S2 for attenuating the brightness of the second screen, and a second procedure for hiding the first content image 30b and displaying a part of the second screen 31 at a predetermined position in the area where the first content image 30b is not displayed. Steps S3, S4, and S5 and a third procedure S6 that hides the first title image 30a and displays the entire second screen are executed.
According to this, it is possible to implement a high-quality display that switches so that the second screen 31 overlaps the first screen 30 with an inexpensive microcomputer that cannot define a plurality of layers that can be overlapped on the screen.

  The embodiment of the present invention has been described above. The present invention is not limited to the above embodiments (including the contents of the drawings). Modifications (including deletion of constituent elements) can be added to the above-described embodiment within the scope of the gist of the present invention.

  For example, in one embodiment of the present invention, when the display is switched from the first screen 30 that displays the current time to the second screen 31 that displays the fuel consumption of the vehicle, the first screen 30 that is the switching source in step S2. However, the present invention is not limited to this, and the display of both the first screen 30 and the second screen 31 is not limited to this, but during the steps S2 to S5 until the screen is switched from the first screen 30 to the second screen 31. The brightness may be attenuated.
