Problems solved by technology

[0002] With the rise of electronic rearview mirrors, more and more car rearview mirrors will use electronic rearview mirrors. There are two main modes of existing electronic rearview mirrors. One is the display mode. Extensive and unobstructed rearview images, the other is the common reflection mode, but at this stage, these two modes are manually switched by the driver. In this case, the safety performance is low, not smart enough, and dangerous accidents are likely to occur
[0003] For example, in the following situations: (1. The reversing distance is too close, and the camera shooting is blurred, which causes the display screen of the electronic rearview mirror to be blurred; 2. In the cold winter, the surface of the camera is frosted, and the camera shooting is blurred, resulting in The display screen is blurred; 3. The surface of the car body and the camera are dirty and dusty, which makes the display screen of the electronic rearview mirror blurred; The shooting is not clear, which leads to the blurred display of the electronic rearview mirror. If the driver does not switch to the normal reflection mode in time, dangerous accidents are likely to occur

Embodiment 1

[0033] Such as figure 1 As shown, a vehicle rear-view assist system includes a rear-view unit, a camera unit, and a processing unit, and the processing unit is electrically connected to the rear-view unit and the camera unit respectively; wherein:

[0034] The rear view unit has a reflection mode and a display mode, the reflection mode is to provide a peripheral picture in the form of reflected light, and the display mode is to provide a peripheral picture in the form of playing images;

[0035] The camera unit is used to acquire peripheral images;

[0036] The processing unit is used to receive the peripheral image acquired by the camera unit, and play the peripheral image on the rear view unit; and is used to judge whether the peripheral image is clear, and if the peripheral image is blurred, control the rear The viewing unit is switched to the reflective mode, and if the peripheral image is clear, the rear viewing unit is controlled to switch to the display mode.

[0037]...

Embodiment 2

[0058] Such as Figure 4 As shown, a control method of the vehicle rear-view assist system described in Embodiment 1 includes the following steps:

[0059] Step 1: the camera unit acquires peripheral images;

[0060] Step 2: the processing unit judges whether the peripheral image is clear;

[0061] Step 3: If the peripheral image is blurred, the processing unit controls the rear view unit to switch to a reflection mode; if the peripheral image is clear, the processing unit controls the rear view unit to switch to a display mode.

[0062] Wherein, after the processing unit receives the peripheral image acquired by the camera unit, it can first display the peripheral image on the rear view unit, and then judge whether the peripheral image is clear, or directly judge whether the peripheral image is clear, And in the display mode of the rear view unit, the peripheral images are displayed on the rear view unit.

[0063] Such as Figure 5 As shown, in step 2, the process of the ...

Abstract

The invention discloses a vehicle rear-view auxiliary system and a control method thereof. The vehicle rear-view auxiliary system comprises a rear-view unit, an image capturing unit and a processing unit, wherein the processing unit is electrically connected to the rear-view unit and the image capturing unit respectively; the processing unit is used for receiving a surrounding image acquired by the image capturing unit and displaying the surrounding image on the rear-view unit; the processing unit is also used for determining whether the surrounding image is clear; the processing unit controls the rear-view unit to switch to a reflection mode if the surrounding image is fuzzy; and the processing unit controls the rear-view unit to switch to a display mode if the surrounding image is clear. The vehicle rear-view auxiliary system and the control method thereof automatically switch the reflection mode and the display mode of a rear-view mirror according to the clarity of captured images, and are safe and reliable.

Description

technical field [0001] The invention relates to a display and camera system, in particular to a vehicle rear view auxiliary system and a control method thereof. Background technique [0002] With the rise of electronic rearview mirrors, more and more car rearview mirrors will use electronic rearview mirrors. There are two main modes of existing electronic rearview mirrors. One is the display mode. Wide, unobstructed rearview images, the other is the common reflection mode, but at this stage the two modes are manually switched by the driver, in this case the safety performance is low, not smart enough, and dangerous accidents are likely to occur. [0003] For example, in the following situations: (1. The reversing distance is too close, and the camera shooting is blurred, which causes the display screen of the electronic rearview mirror to be blurred; 2. In the cold winter, the surface of the camera is frosted, and the camera shooting is blurred, resulting in The display scr...
