Abstract
Disclosed is a vehicle wiper control device which includes: wiper blades that can be disposed on a surface to be wiped and that perform a reciprocating wiping motion between a lower reversal position and an upper reversal position which are set on the surface to be wiped; an electric motor that reciprocates the wiper blades on the surface to be wiped; a drive portion that drives the electric motor; and a load calculation portion that calculates a load on the electric motor while the wiper blades wipe from the upper reversal position to the lower reversal position. If the calculated load value exceeds a predetermined threshold, the drive portion performs wiper stop processing for stopping the wiper blades at the lower reversal position or at a storage position which is set below the lower reversal position.
