Wiper control system and wiper control method

Abstract

The invention provides a wiper control system and a wiper control method and relates to the wiper control system and the wiper control method which can prevent dry brushing. The wiper control system comprises a rain sensor, a controller, a water injector and a wiper; the wiper control system is used for collecting water yield information of the outer surface of a car window; the controller is configured to judge whether water yield is sufficient or not according to the water yield information, a water injection instruction is sent out when the water yield is insufficient, and a wiping instruction is sent out when the water yield is sufficient; the water injector is used for injecting water to the outer surface of the car window according to the water injection instruction of the controller; the wiper is used for wiping out water drops on the outer surface of the car window according to the wiping instruction of the controller. The wiper control method includes: collecting the water yield information of the outer surface of the car window; judging whether the water yield is sufficient or not according to the water yield information, injecting the water to the outer surface of the car window when the water yield required by the outer surface of the car window in insufficient, and wiping out the water drops on the outer surface of the car window when the water yield required by the outer surface of the car window is sufficient. By the arrangement, dry brushing of the wiper can be avoided, and service life of the wiper is prolonged.

Description

technical field [0001] The invention relates to a vehicle wiper system, in particular to a wiper control system and control method capable of preventing dry brushing. Background technique [0002] The wiper is an essential device on the vehicle, especially in harsh environments, such as rain, snow, sand and dust, etc., the use of the wiper can improve the visibility of the driver and increase driving safety. The wiper needs to be used normally in the presence of water, because the rain drops on the wiper and the glass, reducing frictional resistance. If the wiper is used when there is less rainfall or insufficient water spray, it is easy to cause dry brushing and damage the wiper. Contents of the invention [0003] An object of the present invention is to provide a wiper control system and control method, which are used to avoid dry brushing of the wiper when there is little rainfall or insufficient water spray, so as to increase the service life of the wiper. [0004] I...
