Title:
WIPER CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018135097
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To restore rapidly a motion speed of a wiper blade after an overheat state is eliminated.SOLUTION: When a thermistor temperature which is a temperature of a substrate detected by a thermistor 102 is equal to a second threshold or more, a micro computer 58 controls a driving circuit 56 so that a rotation speed of a wiper motor 18 is gradually decreased until the thermistor temperature becomes equal to or less than a first threshold lower than the second threshold. Further, when the thermistor temperature is equal to or less than the first threshold, the micro computer 58 controls the driving circuit 56 so that the rotation speed of the wiper motor 18 is restored at once to a rotation speed according to a switch position of a wiper switch 50.SELECTED DRAWING: Figure 1
