Automatic windscreen wiper control method and system

Abstract

The invention discloses an automatic windscreen wiper control method and system, and relates to the field of automobile control, and the method comprises the steps: obtaining first image data of a front windshield area of a vehicle at a first moment, and detecting the first image definition of the first image data; when detecting that the first image definition is smaller than or equal to a preset image definition threshold value, controlling the windscreen wiper to start wiping; acquiring second image data of the front windshield area of the vehicle at the next moment of the first moment, and detecting the second image definition of the second image data; and according to the first image definition and the second image definition, determining the definition change trend of the vehicle front windshield area, and adjusting the wiping speed of the windscreen wiper according to the definition change trend. According to the invention, the wiping speed of the windscreen wiper can be adjusted according to the change of the real-time rainfall, effective wiping is carried out, the situation that the driving safety is influenced by untimely wiping is avoided, and meanwhile, the situation that the service lives of the windscreen wiper and the windscreen wiper motor are influenced by mistaken wiping or too high wiping frequency is avoided.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to an automatic wiper control method and system. Background technique [0002] Motor vehicles are often equipped with windshield wipers for wiping the windshield in order to ensure a good view of the surroundings for the driver, especially in bad weather conditions. With the improvement of car intelligence, most cars are now equipped with brake-sensitive wipers, which automatically start to wipe when rain is detected. [0003] Most of the automatic wiper control systems currently equipped on vehicles use the rain light sensor arranged on the front windshield to determine the amount of rain through the degree of change in the sensed light to adjust the wiper speed. And because the sensing area of ​​the sensor is limited, there may be situations where raindrops do not fall on the sensing area or other foreign objects fall on the sensing area, resulting in the wiper not wiping or wip...
