- an increasing number of vehicles are equipped with an auto wiper system that detects rainfall and automatically controls the operation of the wiper device.
- the wiper operation is controlled in accordance with the rainfall, and from INT (intermittent operation state) to Lo (low speed operation state: normal operation state) and Hi (high speed operation state) as the rainfall increases.
- the wiper speed is switched appropriately (infinitely depending on the vehicle model).
- Patent Document 1 Conventionally, a configuration as disclosed in Patent Document 1 has been proposed as a means for dealing with a large amount of rainfall such as local heavy rain.
- a wiper device two types of wipers are used as a wiper device: a reciprocating swing type wiper and a rotary wiper.
- the reciprocating rocking wiper is stopped and the rotary wiper is operated. In this way, even during heavy rain, the rain is removed from the windshield to increase the degree of transparency and ensure the driver's visibility.
- a wiper system control method includes a wiper blade that performs a reciprocating wiping operation on a wiping surface, and a raindrop sensor that detects a current rainfall amount based on water droplets adhering to the wiping surface.
- the system control method is characterized in that when a rain of a predetermined amount or more is detected by the raindrop sensor, the wiping range of the wiper blade is narrower than a normal wiping operation.

Therefore, the time required for one wiping operation is shortened, and the range is limited even during heavy rain. Frequently wiped out. Therefore, even in heavy rain in which a large amount of rain adheres to the windshield immediately after the wiping operation, the raindrops are quickly wiped off, and the field of view necessary for the driving operation is ensured.
- the wiper system has a low speed operation state (Lo) in which the wiper blade is operated at a low speed and a high speed operation state (Hi) in which the wiper blade is operated at a higher speed than in the low speed operation state. If the raindrop sensor detects a predetermined amount or more of rain, the wiper blade disposed on the driver side is set in the vicinity of the driver's front field of view and is in a heavy rain wiping area narrower than the normal wiping operation range. Then, it may be operated in the high-speed operation state (Hi).
- the wiper system control device of the present invention includes a wiper blade that performs a reciprocating wiping operation on a wiping surface, and a raindrop sensor that detects a current rainfall amount based on water droplets adhering to the wiping surface.

As a result, the time required for one wipe operation of the wiper blade is shortened, and the range is frequently wiped even during heavy rain. Therefore, even in heavy rain in which a large amount of rain adheres to the windshield immediately after the wiping operation, the raindrops are quickly wiped off, and the field of view necessary for the driving operation is ensured.
- the wiper system has a low speed operation state (Lo) in which the wiper blade is operated at a low speed and a high speed operation state (Hi) in which the wiper blade is operated at a higher speed than in the low speed operation state.
- the operation mode change unit in the heavy rain mode, is configured to remove the wiper blade disposed on the driver side in a heavy rain wiping region narrower than a normal wiping operation range set near the driver's front view. Then, it may be operated in the high-speed operation state (Hi).
- the wiper system control method of the present invention in a wiper system having a raindrop sensor, when the raindrop sensor detects a predetermined amount or more of rain, the wiper blade wiping range is narrower than the normal wiping operation. Even at times, the predetermined wiping range is frequently wiped, and the field of view necessary for the driving operation can be secured. Therefore, even in the case of local heavy rain, it is possible to secure a field of view until the vehicle is evacuated to a safe place.
- the present invention can be applied to a conventional wiper system by improving the control software without changing the device configuration. Therefore, the visibility during heavy rain can be ensured without complicating the system structure and increasing the cost. Is possible.
- the operation mode changing unit changes the operation mode of the wiper blade to heavy rain. Since the mode is changed to the mode and the wiping range is narrower than the normal wiping operation, the predetermined wiping range is frequently wiped even during heavy rain, and the field of view necessary for the driving operation can be secured. Therefore, even in the case of local heavy rain, it is possible to secure a field of view until the vehicle is evacuated to a safe place.
- the present invention can be applied to a conventional wiper system by improving the control software without changing the device configuration. Therefore, the visibility during heavy rain can be ensured without complicating the system structure and increasing the cost. Is possible.

That is, the wiper control devices 10a and 10b first perform forward / reverse control of the motors 6a and 6b based on the blade position on its own side. At the same time, the wiper control devices 10a and 10b control the motors 6a and 6b based on the blade position information of both blades 2a and 2b, and control the wiper system so that the blades do not interfere with each other and the angle difference does not increase. .
