Problems solved by technology

[0003] First, the virtual digital instrument is an instrument based on the UI interface display. The brightness of the display is relatively large and is always on. Since the position of the display is below the driver's field of vision, it is easy to interfere with the driver's sight.
[0004] Second, the driver spends most of his time observing the information on the road ahead, and usually only pays attention to the instrument information when the instrument fails, so the display screen will always be on and a lot of energy will be wasted

Embodiment Construction

[0045] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0046] Embodiments of the present invention provide an instrument backlight control method on the one hand, including:

[0047] Step 1. Check whether the parameters displayed by the meter are normal, and judge whether the backlight of the meter is on.

[0048] The parameters displayed on the car instrument mainly include numerical values ​​and prompt warnings. Numerical values ​​include speed, rotational speed, engine water temperature, oil level, etc. Prompt warnings include door open alarms, engine failure alarms, ABS failure alarms, etc. During specific implementation, it is determined whether each parameter displayed by the instrument is normal by setting the normal threshold range of each par...

Abstract

The invention provides an instrument backlight control method and device. On-off of backlight is determined by judging various parameters displayed by an instrument and the backlight state of the instrument; when the parameters displayed by the instrument are normal, the backlight of the instrument is switched off after preset time; when the parameters displayed by the instrument are abnormal, the backlight state is determined according to the abnormality level; when the backlight is switched on, the luminance of the backlight is adjusted to be proper according to the luminance of ambient light. Automatic control over the backlight state of the instrument is achieved, driving safety is improved, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to an instrument backlight control method and device. Background technique [0002] Virtual digital instrument is a popular car instrument at present, with low hardware cost, more vivid display effect and strong sense of technology, it is the development trend of future car instrument. However, virtual digital instruments have the following disadvantages: [0003] First, the virtual digital instrument is an instrument based on the UI interface display. The brightness of the display screen is relatively large and is always on. Since the position of the display screen is below the driver's field of vision, it is easy to interfere with the driver's sight. [0004] Second, the driver spends most of his time observing the information on the road ahead, and generally only pays attention to the instrument information when the instrument fails, so a large amount of energy wi...
