Abstract
A wiper control device that properly detects restriction of a wiper blade according to a travel distance of the wiper blade. When a state in which a rotation speed of an output shaft calculated from a rotation angle of the output shaft detected by a rotation angle sensor is equal to or slower than a speed threshold defined according to a travel distance of the wiper blade and in which a current detected by a current detector is equal to or larger than a current threshold continues for a predetermined determination period, a microcomputer stops a wiper motor or reverses a direction of a wiping action of the wiper blade.
