Abstract
Official abstract text for this publication.
A vehicle wiper device includes: a first blade having an operating range that includes an upper mid region of a vehicle windshield; a second blade having an operating range that includes a lower region of the operating range of the first blade; a cleaning-liquid feeding unit; a blade driving unit that causes each blade to reciprocate; and a controller that controls operation of the cleaning-liquid feeding unit and operation of the blade driving unit. The controller performs the control such that, after a series of normal operation in which the first blade and the second blade reciprocate while ejecting the cleaning liquid has been completed, additional movement operation is performed in a state where feeding of the cleaning liquid from the cleaning-liquid feeding unit is stopped.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle wiper device comprising: a first blade having an operating range that includes an upper mid region of a vehicle windshield; a second blade having an operating range that includes a lower region of the operating range of the first blade; a cleaning-liquid feeding unit that feeds a cleaning liquid to an ejector so as to eject the cleaning liquid onto the windshield; a blade driving unit that causes each blade to reciprocate within the corresponding operating range on the windshield; and a controller that controls operation of the cleaning-liquid feeding unit and operation of the blade driving unit, wherein the controller controls the cleaning-liquid feeding unit and the blade driving unit such that, after a series of normal operation in which the first blade and the second blade reciprocate while ejecting the cleaning liquid has been completed, additional movement operation is performed by either one of the first blade and the second blade or by both the first blade and the second blade at different timings in a state where feeding of the cleaning liquid from the cleaning-liquid feeding unit is stopped, and wherein when the controller causes the first blade to perform the additional movement operation, the controller performs the control such that a moving range of the first blade in the movement operation is set to be larger than a moving range of the first blade in the normal operation. 2. A vehicle wiper device comprising: a first blade having an operating range that includes an upper mid region of a vehicle windshield; a second blade having an operating range that includes a lower region of the operating range of the first blade; a cleaning-liquid feeding unit that feeds a cleaning liquid to an ejector so as to eject the cleaning liquid onto the windshield; a blade driving unit that causes each blade to reciprocate within the corresponding operating range on the windshield; and a controller that controls operation of the cleaning-liquid feeding unit and operation of the blade driving unit, wherein the controller controls the cleaning-liquid feeding unit and the blade driving unit such that, after a series of normal operation in which the first blade and the second blade reciprocate while ejecting the cleaning liquid has been completed, additional movement operation is performed by either one of the first blade and the second blade or by both the first blade and the second blade at different timings in a state where the feeding of the cleaning liquid is stopped only during a returning motion in the additional movement operation, and wherein when the controller causes the first blade to perform the additional movement operation, the controller performs the control such that a moving range of the first blade in the movement operation is set to be larger than a moving range of the first blade in the normal operation.
