Title: Wiper control method and wiper control device

Abstract: A wiper control method and a wiper control device are provided which can smoothly respond to rapid change of a rainfall situation at passage of a rainfall shutoff environment such as a tunnel. A wiping state control part 42 determines entry of a vehicle into the rainfall shutoff environment, sets a wiping level low for the low level of rainfall less than a predetermined rainfall level in response to this determination or sets the wiping level high for the high level rainfall at the predetermined rainfall level or more. A rainfall level generation part 32 detects adhesion of raindrops and determines the rainfall level. A wiper driving signal generation part 48 determines wiper operation based on the rainfall level determined by the rainfall level generation part 32 and the wiping level set by the wiping state control part 42.
