Problems solved by technology

However, even with a system equipped with a raindrop sensor, when a large amount of rain falls such as sudden localized rainstorms, storms, or showers, there may be a large amount of rainwater immediately after the wipe operation even if the wiper operation is set to Hi. On the windshield, it is difficult to secure a field of view
Especially in the case of "downpour" in which the rainfall exceeds 50 mm per hour, the forward visibility will be deteriorated, and even if the vehicle is to be evacuated to an appropriate place to ensure safety, it may be difficult to drive

Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. An object of the present embodiment is to provide a wiper system capable of securing a driver's minimum field of vision even in heavy rainfall such as a local heavy rain without complicating the system structure or increasing the cost. figure 1 It is an explanatory diagram showing the overall configuration of a wiper system driven by a wiper control method and a control device according to an embodiment of the present invention. figure 1 The wiper system has a wiper arm 1a on the driver's seat side and a wiper arm 1b on the passenger's seat side. The wiper arms 1a, 1b are swingably provided on the vehicle body. figure 1 The wiper system of the car has a so-called automatic wiper system. If the wiper switch is set to Auto (automatic wiper mode), its operation is automatically controlled according to the amount of rain.

Abstract

A wiper system according to the present invention is provided with wiper blades (2a, 2b) for performing a reciprocal wiping operation on a front glass (3), and a rain drop sensor (9) that senses the current amount of rainfall on the basis of rain drops attached to the front glass (3). When a predetermined amount or more of rainfall is detected by the rain drop sensor (9), heavy rain mode is implemented to narrow the wiping range of the wiper blades (2a, 2b) compared to the wiping range of normal wiping operation. In the heavy rain mode, the wiper blade (2a) located on the driver side is operated at high speed (Hi) in a heavy rain wiping region (X) set around the forward field of view of the driver so as to ensure the driver's field of view.

Description

technical field [0001] The present invention relates to a control method and device for a wiper system mounted on a vehicle such as an automobile, and more particularly to an effective technique applied to a wiper system equipped with a raindrop sensor (rain sensor) for detecting rainfall. Background technique [0002] In recent years, from the viewpoint of safety and convenience, the number of vehicles equipped with an automatic wiper system that detects rainfall and automatically controls the operation of the wiper device is increasing. In such a wiper system, the operation of the wiper is controlled according to the amount of rain, and as the amount of rainfall increases, the speed of the wiper is appropriately changed from INT (intermittent operation state) to Lo (low speed operation state: normal operation state), Hi ( High-speed working state) switching (stepless switching according to the vehicle type). However, even with a system equipped with a raindrop sensor, whe...
