Abstract
There are provided a wiper control method and a wiper control device in which unnecessary wiping operation is not performed. When a fixed amount of water passing through a detection area 4, the water being carried by the wiping operation of a wiper 5b, is detected, the presence of impact of a raindrop on the detection area 4 is judged. When there is no impact of a raindrop on the detection area 4, it is judged that water that is carried by the wiper 5b and passes through the detection area 4 is caused by a factor other than rainfall, and control is carried out to decrease the frequency of wiping operation of the wiper.
