Wiper controller for controlling windshield wiper
First Claim
1. A wiper controller comprising:
- a sensor for detecting a waterdrop disposed on a windshield of a vehicle;
a wiper disposed on the windshield for wiping the windshield; and
control means for controlling operation of the wiper on the basis of amount of the waterdrop, wherein the control means monitors a waterdrop reflection caused by the waterdrop when the sensor detects the waterdrop disposed on the windshield, the waterdrop reflection is a diffuse reflection of light entered from an external light source into a compartment of the vehicle through the waterdrop and the windshield, and the control means operates the wiper with an intermittent wiping operation having a time interval in such a manner that the time interval in a case where the control means decides nonexistence of the waterdrop reflection is set to be longer than the time interval in a case where the control means decides existence of the waterdrop reflection.

Abstract
A wiper controller includes: a sensor for detecting a waterdrop on a windshield; a wiper for wiping the windshield; and control means for controlling operation of the wiper. The control means monitors a waterdrop reflection when the sensor detects the waterdrop. The waterdrop reflection is a diffuse reflection of light. The control means operates the wiper with an intermittent wiping operation having a time interval in such a manner that the time interval in a case where the control means decides nonexistence of the waterdrop reflection is set to be longer than the time interval in a case where the control means decides existence of the waterdrop reflection.

14. A wiper controller comprising:
-
a sensor for detecting a waterdrop disposed on a windshield of a vehicle;
a wiper disposed on the windshield for wiping the windshield; and
control means for controlling operation of the wiper on the basis of amount of the waterdrop, wherein the control means monitors a degree of a waterdrop reflection caused by the waterdrop when the sensor detects the waterdrop disposed on the windshield, the waterdrop reflection is a diffuse reflection of light entered from an external light source into a compartment of the vehicle through the waterdrop and the windshield, and the control means operates the wiper with an intermittent wiping operation having a time interval in such a manner that the time interval is set to be longer as the degree of the waterdrop reflection decided by the control means becomes smaller. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
