Claims

[Scope of Claim for Utility Model Registration] Rainfall detection means that detects rainfall and generates an electrical signal; Integration means that calculates the amount of rainfall by integrating the electrical signals from the rain detection means; and an integrated value of the integration means that is determined in advance. determined first
wiper operating means that operates the wiper for a certain period when the rainfall is higher than the standard value; reset means that resets the integrated value in the integrating means when the wiper is activated; , as well as the reset means, a timer that resets the integrated value in the integration means, and a timer that clears the time measured by the timer when the electrical signal from the rain detection means is on the heavy rainfall side than a predetermined second reference value. A wiper control device for a vehicle, comprising: a clearing means;
