ABSTRACT:
A wiper control device for a vehicle with a wiper includes a day
ight detecting device for detecting whether the vehicle is in day-like or night-like conditions. The device also includes a moisture detection device that detects a quantity of moisture on the vehicle and a controlling device that controls the wiping action of the wiper based on a wiping sensitivity to the quantity of moisture detected. The controlling device adjusts the wiping sensitivity between night-like wiping sensitivity and day-like wiping sensitivity. The controlling device adjusts wiping sensitivity to night-like wiping sensitivity when the day
ight detecting device detects night-like conditions and to day-like wiping sensitivity when the day
ight detecting device detects day-like conditions. Additionally, when the day
ight detecting device detects a change between day-like and night-like conditions, the controlling device delays switching between night-like and day-like wiping sensitivity for a predetermined delay time.
