  • Wiper control apparatus
    Patent number: 8569985
    Abstract: In a wiper control apparatus, a water drop detector outputs an output signal in accordance with water drops adhering to a windshield of a vehicle. When a traveling determination portion determines that the vehicle is traveling, a first level setting portion sets a sensitivity for detecting the output signal to a first sensitivity. When the traveling determination portion determines the vehicle is not traveling, a second level setting portion sets the sensitivity for detecting the output signal to a second sensitivity that is larger than the first sensitivity. A water drop adhesion determination portion determines that water drops adhere to the windshield when a determination waiting time elapses in a state where detection of the output signal continues. A driving control portion controls a wiper driving portion to drive the wiper when the water drop adhesion determination portion determines that water drops adhere to the windshield.
