Abstract
First and second temperature check portions 7 and 8 determine whether an ambient temperature T1 is lower than 20° C. or not, whether an external surface temperature T2 of a windshield S is lower than 25° C. or not and whether a temperature difference (T2−T1) is lower than 20° C. or not, and a weather condition check portion 9 determines whether a condition that condensation occurs over the windshield S is met or not based on results of the checks. A wiper control portion 10 controls a driving operation of a wiper W based on a rainfall state checked by a low sensitivity rainfall check portion 5 when the condition that the condensation occurs is met, and controls the driving operation of the wiper W based on a rainfall state checked by a high sensitivity rainfall check portion 4 when a condition that the condensation does not occur is met.
