Wipe control system and method for windshield shading area

Abstract

The invention provides a wipe control system and method for a block region of a windshield. The system comprises an image shooting device, a block region identification module and a windshield wiper controller, wherein the image shooting device is aligned to the windshield and shoots images in real time, so that original images at least containing a windshield wiper region are continually obtained; the block region identification module receives the original images in real time, identifies the block region in the original images and locates the coordinate and the region range of the block region in the original images; a plurality of branch wipe regions used for dividing the windshield wiper region are arranged in the block region identification module in advance, the corresponding branchwipe regions is selected according to the coordinate and the region range so as to generate a first block region characteristic value and generate a first branch wipe instruction; the windshield wipercontroller determines the upper and lower limit range of a windshield wiper according to the first block region characteristic value, adjusts the upper and lower limit range of a windshield wiper according to the change of the first block region characteristic value, and at least responds to the first branch wipe instruction to control the windshield wiper to wipe repeatedly in the upper and lower limit range of the windshield wiper. By means of the wipe control system, it is achieved that obstructions are quickly wiped, so that it is avoided that the obstructions have an impact on driving safety.

Description

technical field [0001] The invention relates to vehicle wiper control technology, in particular to a control system and method for wiping the shielded area of ​​a windshield. Background technique [0002] The wiper wiping system of existing vehicles generally completes glass wiping by reciprocating periodic motion on the entire wiper area, covering all ranges that the wiper of the windshield can run to. However, the windshield is often blocked by the windshield due to mud, insect and bird feces and other dirt falling on it. In response to this phenomenon, the original wiping system has the following technical disadvantages: no distinction is made between the occluded area and the non-occluded area; in this way, the key occluded area cannot be quickly wiped, which affects the line of sight; It is enlarged, resulting in larger occluded areas and affecting the field of vision; in addition, excessive wiping in non-occluded areas will also cause unnecessary wear of the rubber st...

Problems solved by technology

However, the windshield is often blocked by the windshield due to mud, insect and bird feces and other dirt falling on it.

In response to this phenomenon, the original wiping system has the following technical disadvantages: no distinction is made between the occluded area and the non-occluded area; in this way, the key occluded area cannot be quickly wiped, which affects the line of sight; It is enlarged, resulting in larger occluded areas and affecting the field of vision; in addition, excessive wiping in non-occluded areas will also cause unnecessary rubber strip wear

Especially for the application field of autonomous driving, when the area of ​​the windshield that affects video capture is suddenly blocked, it needs to be wiped as quickly as possible, otherwise driving safety will be affected
