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 part42determines 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 part32detects adhesion of raindrops and determines the rainfall level. A wiper driving signal generation part48determines wiper operation based on the rainfall level determined by the rainfall level generation part32and the wiping level set by the wiping state control part42.
