Claims (1)

[Scope of utility model registration request] In a vehicle wiper control device that automatically determines the wiper operating mode and performs wiper control based on the amount of rainfall detected by a rainfall amount detection means, the detected amount of rainfall and preset upper and lower limit reference values are used. and a second comparison means that measures the elapsed time since the last time the wiper wiped when the wiper is intermittently operated, and compares this elapsed time with the average value of the latest past intermittent times. a comparison means; when the amount of rainfall is equal to or higher than a preset lower limit reference value and the elapsed time since the previous wiper wiping exceeds the average value of the intermittent time; wiper control means that wipes the wiper when the detected amount of rainfall exceeds a preset upper limit reference value even when there is no rain, and stops the wiper operation when the amount of rainfall is less than the lower limit reference value; A wiper control device for a vehicle, comprising: mode switching means for switching wiper operation to a continuous mode when the average value of the intermittent times is shorter than a predetermined value.
