Problems solved by technology

Therefore, although the driver is less likely to feel bothered by the brightness of the display of the instrument device when driving in an urban area where the surrounding environment is bright, the driver may feel disturbed when driving on a suburban road where there are only few street lights. trouble
The full graphic instrumentation as described above has a function to adjust the brightness; however, this reduces the brightness of the entire instrumentation, and thus also reduces the display brightness of the speedometer etc. which the driver always needs to look at, resulting in reduced visibility

Embodiment Construction

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a block diagram showing a hardware configuration of a vehicle display device according to an embodiment of the present invention. Such as figure 1 As shown, the vehicle display device 1 includes a CPU 2, GDC3, a liquid crystal display 4, and an EEPROM 8.

[0032] The CPU 2 includes ROM 21, RAM 22, and Network Unit (CAN) 23. ROM 21 Storage Control Program, etc. RAM 22 is used as a work area.

[0033] The network unit 23 communicates with other devices via communication I / F 7 according to the CAN (controller local area network) standard, and inputs various vehicle information. Further, information on other devices such as speed sensor 11, obstacle sensor 12, lamp switch (SW) 13, and mode switching switch (SW) 14 is connected to the network unit 23.

[0034] The speed sensor 11 detects the speed of the vehicle mounted and the vehicle display device 1 (i.e., th...

Abstract

Provided is a vehicle display device capable of reducing the visual recognition burden of a driver and shortening the viewing time. A display device for a vehicle includes: a liquid crystal display including a first region, a second region, and a third region as display regions; and a CPU configured to switch the liquid crystal display between a normal display mode and a simple display mode. The CPU is configured to: cause the first area, the second area, and the third area to display vehicle information in a normal display mode; and in the simple display mode, the first area and the second area are placed in a non-display state, and only the third area displays at least speed information in the vehicle information in a digitally indicated manner.

Description

Technical field [0001] The present invention relates to a vehicle display device configured to be mounted on a vehicle. Background technique [0002] Recently, as an instrumentation device for vehicles, a full graphic instrument device (also referred to as a full digital instrument device) such as a TFT (thin film transistor) liquid crystal display is increasingly used. In addition, the size of the display itself is increasing, not only the speedometer, and many other content (ie, vehicle information) are also displayed in the instrument device such that the driver is difficult to find the information that the driver wants to check during driving. [0003] In a full graphic instrument device using a large display, in many cases, it is configured such, for example, when the display brightness is lowered during night, or use the night display color. Therefore, although driving when driving in a bright urban area in the surrounding environment, the driver is unlikely to feel the har...
