する車両用オートワイパ。 a mode selection means for selecting between an auto mode and a plurality of manual modes; and a mode selection means for determining whether or not a detection signal of a rain sensor is equal to or greater than a determination threshold when the auto mode is selected by the mode selection means, and determining a determination result. an automatic wiper drive control means for controlling the wiper wiping speed based on the above, and a one-way switching of the mode selection means to change the detection signal value of the rain sensor at the time of the switching as a threshold value for determining when the amount of rain increases. By switching the possible rainfall increase threshold setting means and the mode selection means in the other direction, the rain sensor detection signal value at the time of switching can be changed as a threshold for determining when the rainfall decreases. The threshold for determining when the amount of rainfall increases is set not to be lower than the threshold for determining when the amount of rainfall decreases, and the threshold for determining when the amount of rainfall decreases is set to be equal to the threshold for determining when the amount of rainfall increases. An automatic wiper for a vehicle, characterized in that a threshold value for determining when the amount of rainfall increases or decreases has a hysteresis characteristic so that the threshold value is not exceeded.
