A wiper control technique is provided that can prevent a windshield from being damaged by a falling wiper blade during a wiper parking operation, even when a wiper arm is in a retreat position where the blade is raised and held away from the windshield. In one embodiment, the wiper arm is stopped for a predetermined time interval at a predetermined pause position when the wiper arm is positioned above a parked position and at the retreat position during the wiper parking operation, while the wiper arm is being swung downward toward a lower reversal position. The pause position is a position at which the wiper arm is able to fall toward the windshield to return to a base position. After a lapse of the predetermined time interval, the wiper arm is swung to the parked position.
A wiper control method for a wiper apparatus which includes a wiper having a wiper blade that wipes a windshield of a vehicle and a wiper arm that has the wiper blade attached thereto and is capable of swinging about a predetermined pivot shaft along a surface of the windshield together with the wiper blade, and a drive part that causes the wiper to swing along the surface of the windshield to and from between a predetermined upper reversal position and a predetermined lower reversal position, wherein the wiper apparatus has a configuration capable of enabling lock back whereby the wiper arm is moved from a base position at which the wiper blade is made to contact the windshield to a retreat position at which the wiper blade is raised and held away from the windshield, and capable of parking the wiper at a predetermined parked position located below the lower reversal position and between a back end of an engine hood and the windshield, the method comprising:
