Embodiment 1

[0024] figure 1 is a schematic block diagram of a windshield wiper system according to Embodiment 1 of the present invention. like figure 1 As shown, the windshield wiper system 100 includes: at least one wiper blade 10 for wiping the windshield of the vehicle; Provide driving force; water sensor 30 for detecting the amount of water on the windshield, for example, water sensor 30 can be a humidity sensor; and control unit 40, which is connected with wiper drive unit 20 and water sensor 30.

[0025] Specifically, when the user of the vehicle operates the wipe lever of the vehicle, a wipe instruction will be sent to the control unit 40 . When the control unit 40 receives a wiping instruction indicating that the user intends to wipe the windshield for the first time within a predetermined period and the amount of water on the windshield detected by the water sensor 30 is lower than a threshold value, the control unit 40 It is configured to deactivate the wiper drive unit 20 an...

Embodiment 2

[0040] image 3 is a schematic block diagram showing a windshield wiper system according to Embodiment 2 of the present invention. like image 3As shown, the windshield wiper system 200 includes: at least one wiper blade 10 for wiping the windshield of the vehicle; A driving force is provided; a water quantity sensor 30 is used to detect the amount of water on the windshield; a washer fluid drive unit 60 is used to spray washer fluid from the washer fluid tank onto the windshield; and a control unit 40 is connected to the wiper drive unit 20. The water volume sensor 30 is connected to the cleaning fluid drive unit 60 .

[0041] Specifically, when the control unit 40 receives a dust removal command indicating that the user of the vehicle intends to spray the washer fluid to the windshield and scrape the windshield, the control unit 40 first activates the washer fluid drive unit 60, and then receives the signal detected by the water volume sensor 30. If the water quantity on ...

Abstract

The invention discloses a windshield wiper system and a vehicle with the windshield wiper system. The windshield wiper system comprises at least one wiper blade, a wiper driving unit, a water amount sensor and a control unit; the wiper blades are used for wiping a windshield of the vehicle; the wiper driving unit is connected with the wiper blades and used for providing driving force for the wiperblades; the water amount sensor is used for detecting the amount of water on the windshield; the control unit is connected with the wiper driving unit and the water amount sensor, wherein under the conditions that the control unit receives a wiping instruction representing that a vehicle user intends to wipe the windshield for the first time within a predetermined period and the amount, detectedby the water amount sensor, of the water on the windshield is lower than a threshold value, the control unit is configured not to activate the wiper driving unit.

Description

technical field [0001] The invention relates to a windshield wiper system and a vehicle having the windshield wiper system. Background technique [0002] The windshield wiper system is essential to the safe operation of the vehicle. The wiper blades are designed to wipe off the rain automatically when the water level sensor detects that there is more than a certain amount of rain on the windshield that will affect the user's visibility. The windshield wiper system can also be used to clean the windshield of dust, but it should be used with washer, the washer should be sprayed on the windshield first, and then the wiper blades work. Vehicles usually have specific modes of operation for this purpose. [0003] However, current windshield wiper systems cannot avoid operating the wiper blades while the windshield is dry, which increases friction between the wiper blade and the surface of the windshield, and damages the wiper blade. What's worse, when the surface of the windshi...
